The Synthetic A Priori

This paper engages with the epistemological foundations of Integrated Information Theory (IIT), which have recently been questioned from different angles. A recurrent motif of the skeptical attacks involves IIT’s central identity, according to which a particular conscious experience is identical with a particular Maximally Irreducible Cause-effect Structure (MICS). This implies that the same existence is described by the axioms from the phenomenological perspective, and by the postulates in causal terms. My argument is meant to strengthen the theory’s foundations by showing (...) that the identity is a constitutive a priori first principle. In virtue of this status, <Experience = MICS> has a number of functions within the theory. In particular, it allows the information-theoretic formalism of the postulates to be applied to the phenomenology captured by the axioms; it imbues phenomenological concepts with empirical meaning, and assures the possibility of assessing the theory’s explanations and predictions in a scientific sense; it constructs IIT’s proper object of study, i.e., consciousness as maximally irreducible, specific, structured, intrinsic cause-effect power; and, as full-fledged transcendental, it deals with the invariant structures of all experience, and makes possible other a priori explanatory principles. Through Michael Friedman’s defense of constitutive a priori principles in spacetime physics, the present paper draws a first parallel between Kant’s transcendental philosophy and IIT’s epistemological foundations. However, my interpretation keeps closer to the Kantian root of apriority, and shows that IIT is a transcendental theory of its own, one that might surpass even Kant’s own expectations of his project.

The concept of a priori plays an important role in Kant’s entiree philosophy. However, Husserl often claimed that a genuine concept of a priori in the phenomenological sense was absent in Kant. Scheler criticized this concept of Kant just as Husserl did. All of Scheler’s ethical critiques of Kant, who is the major opponent to Scheler, are based on his critiques of Kant’s concept of a priori because, for Scheler, it is the largest absurdity of Kant’s theory that a priori (...) is equated to the formal. Scheler thus clearly delineated Kant’s transcendentalism, which seeks a priori in form. It seems that Scheler‘s comprehension and interpretation of a priori reversed Kant’s “Copernican revolution”, in contrast with which, Scheler carried ou a „Ptolemiac counter-revolution“. In fact, Scheler questioned Kant‘s transcendental-rational theory of the function of synthetic categories, which derived from the “Copernican revolution”. Nevertheless, Scheler did not want to defend the pre-Kant position, or Kant’s pre-critique period. He also did not mean simply to stress one side in Kant’s dualism , which was ignored by Kant. In fact, he wanted to question Kant’s metaphysical dualism itself. The eventual goal of his phenomenological philosophy is to reveal the uncritical presuppositions in Kant’s critical philosophy.

There is a divide in epistemology between those who think that, for any hypothesis and set of total evidence, there is a unique rational credence in that hypothesis, and those who think that there can be many rational credences. Schultheis offers a novel and potentially devastating objection to Permissivism, on the grounds that Permissivism permits dominated credences. I will argue that Permissivists can plausibly block Schultheis' argument. The issue turns on getting clear about whether we should be certain whether our (...) credences are rational. (shrink)

On défend ici l'hypothèse selon laquelle les relations d'idées humiennes ont pu servir de matrice à la constitution d'un a priori phénoménologique, en un sens particulier : conçues d'abord comme relations internes, elles ont dû être partiellement arrachées à un modèle représentationnel hérité de Brentano et insérées dans un dispositif ontologique, s'exprimant alors selon une modalité qui est celle du rapport d'essence. One suggests the possibility that Hume's relations of ideas must have constituted the basis of the phenomenological synthetic a (...) priori, in a specific sense : first considered as internal relations, they must have been partially snatched out of the representational context -a legacy of Franz Brentano -, beeing then expressed in terms of ontological structures, relations of essences.

How is moral knowledge possible? This paper defends the anti-Humean thesis that we can acquire moral knowledge by deduction from wholly non-moral premises. According to Hume’s Law, as it has become known, we cannot deduce an ‘ought’ from an ‘is’, since it is “altogether inconceivable how this new relation can be a deduction from others, which are entirely different from it” (Hume, 1739, 3.1.1). This paper explores the prospects for a deductive theory of moral knowledge that rejects Hume’s Law.

One of the central figures of philosophy of language- John Langshaw Austin, attributes principles of causation to the mere pragmatic language. Conversely, Kant tried to construct a “free human act” which is independent from any physical determination except its innate motivations via his well-known the phenomenal / noumenal distinction. That kind of Kantian metaphysical ground which addresses to the noumenal field, he obviously tries to establish this behavioral causation again by denying Austinian style pragmatic propositions or illocutionary acts. I claimed (...) that sort of duality between Austin and Kant, creates an epistemological problem with how propositions and actions relate. From a Kantian position, it (indetermination) is overlooked by Austin's propositional doctrine, without being grounded on any universal principle, but only with propositions that embraced by speech act theory.

Some philosophers, like Kripke, Williamson, Hawthorne, and Turri, have offered examples of claims that are allegedly contingent and a priori justifiable. If any of these examples is genuine, this would upend the traditional epistemological classification on which (a) all and only a priori justifiable claims are necessary and (b) all and only a posteriori ones are contingent. I argue here that these examples are not genuine. This conclusion is not new, but the strategy pursued here is to formalize these muchdiscussed (...) examples in symbolic logics. Once formalized, a perspicuous representation of their logical form will bring into sharp relief that these examples are not both contingent and a priori. Two takeaways are (1) that the traditional epistemological classification remains plausible and (2) that one’s proposed examples of contingent a priori claims should be supported by a formalization in one’s preferred background symbolic logic.

The paper addresses the question of the nature and limits of philosophical thought experiments. On the one hand, experimental philosophers are right to claim that we need much more laboratory work in order to have more reliable thought experiments, but on the other hand a naturalism that is too radical is incapable of clarifying the peculiarity of thought experiments in philosophy. Starting from a historico-critical reconstruction of Kant’s concept of the “experiments of pure reason”, this paper outlines an account of (...) thought experiments in philosophy that tries to reconcile the thesis of a principled difference between scientific and philosophical TEs with the position of a methodological naturalism that does not admit any difference in kind between the methods of science and of philosophy.

Agustín Rayo’s The Construction of Logical Space offers an exciting and ambitious defense of a broadly Carnapian approach to metaphysics. This essay will focus on one of the main differences between Rayo’s and Carnap’s approaches. Carnap distinguished between analytic, a priori “meaning postulates”, and empirical claims, which were both synthetic and knowable only a posteriori. Like meaning postulates, they determine the boundaries of logical space. But Rayo is skeptical that the a priori/a posteriori or analytic/synthetic distinctions can do the work (...) Carnap wanted them to, so unlike meaning postulates, ‘just is’-statements aren’t assumed to be analytic or knowable a priori. This essay will concern the epistemology of ‘just is’-statements in Rayo’s picture. If not by a priori reflection, how can we determine which ones to accept? I’ll distinguish two competing strands in Rayo’s work. The less radical, Lewisian strand holds that the question of whether to accept a ‘just is’-statement can be addressed in a neutral, non-question-begging way, by a kind of cost-benefit analysis. The more radical, Kuhnian strand holds that there can be no ‘just is’-statement-independent, rational choice of which ‘just is’-statements to accept. I argue that Rayo faces strong internal pressure to adopt the Kuhnian picture. While it is possible for Rayo to resist these Kuhnian pressures, natural strategies for doing so leave his view more similar to Carnap’s than the above gloss suggested. (shrink)

Poincaré is well known for his conventionalism and structuralism. However, the relationship between these two theses and their place in Poincaré׳s epistemology of science remain puzzling. In this paper I show the scope of Poincaré׳s conventionalism and its position in Poincaré׳s hierarchical approach to scientific theories. I argue that for Poincaré scientific knowledge is relational and made possible by synthetic a priori, empirical and conventional elements, which, however, are not chosen arbitrarily. By examining his geometric conventionalism, his hierarchical account of (...) science and defence of continuity in theory change, I argue that Poincaré defends a complex structuralist position based on synthetic a priori and conventional elements, the mind-dependence of which precludes epistemic access to mind-independent structures.

Kant's philosophy promises to explain various synthetic a priori claims. Yet, as several of his commentators have noted, it is hard to see how these explanations could work unless they themselves rested on unexplained synthetic a priori claims. Since Kant appears to demand explanations for all synthetic a priori claims, it would seem that his project fails on its own terms. I argue, however, that Kant holds that explanations are required only for synthetic a priori claims about (purportedly) experience-independent entities, (...) and that his project rests on a rationalist method of reflection that justifies certain basic synthetic a priori claims.

We examine the sense in which logic is a priori, and explain how mathematical theories can be dichotomized non-trivially into analytic and synthetic portions. We argue that Core Logic contains exactly the a-priori-because-analytically-valid deductive principles. We introduce the reader to Core Logic by explaining its relationship to other logical systems, and stating its rules of inference. Important metatheorems about Core Logic are reported, and its important features noted. Core Logic can serve as the basis for a foundational program that could (...) be called Natural Logicism, an exposition of which will build on the (meta)logical ideas explained here. (shrink)

English title: The Problem of the Synthetic a priori Judgements According to Hermann Lotze. The present article compares Kant’s and Lotze’s concepts of synthetic judgements. Lotze’s aim is a renewing of the Kant’s solutions, what he achieves thanks to introduction of the distinction between analytic (identical) content and synthetic form of these judgements which Kant recognised as synthetic. This distinction makes possible to lay down the concept of intentional sense which has influence over Frege and Husserl.

This book critically examines some widespread views about the semantic phenomenon of reference and the cognitive phenomenon of singular thought. It begins with a defense of the view that neither is tied to a special relation of causal or epistemic acquaintance. It then challenges the alleged semantic rift between definite and indefinite descriptions on the one hand, and names and demonstratives on the other—a division that has been motivated in part by appeals to considerations of acquaintance. Drawing on recent work (...) in semantics, the book explores a more unified account of all four types of expression, according to which none of them paradigmatically fits the profile of a referential term. On the proposed framework, all four involve existential quantification but admit of uses that exhibit many of the traits associated with reference—a phenomenon that is due to the presence of what we call a ‘singular restriction’ on the existentially quantified domain. The book concludes by drawing out some implications of the proposed semantic picture for the traditional categories of reference and singular thought. (shrink)

In the 19th century, a transition took place from the classical to the modern ideal of science: Science would no longer be regarded as a categorical-deductive system of absolute truths, but instead as a hypothetical-deductive system of problematically conditional propositions. In this process, the synthetic a priori also took on more and more of the status of something problematically conditional, which could be found out and corrected empirically, and was itself even ultimately contingent upon empiricism. Along the way, it lost (...) its original purpose, namely to formulate the conditions for the possibility of objective knowledge. To the extent that one continues to attribute objectivity to scientific knowledge, however, the question of the synthetic a priori remains current. The present volume aims to trace the historical roots and varied interpretations of the synthetic a priori while also seeking new approaches toward a contemporary reinterpretation of this fundamental concept. // -/- Im 19. Jahrhundert vollzieht sich der Übergang vom klassischen zum modernen Wissenschaftsideal: Die Wissenschaft wird nicht mehr als kategorisch-deduktives System absoluter Wahrheiten, sondern als ein hypothetisch-deduktives System problematisch-konditionaler Sätze angesehen. Damit erlangt auch das synthetische Apriori mehr und mehr den Status von etwas Problematisch-Konditionalem, das vermöge der Empirie aufgefunden und nachkorrigiert wird, schlussendlich sogar selbst von der Empirie abhängt. Es büßt dabei seinen ursprünglichen Zweck ein, nämlich die Bedingungen der Möglichkeit objektiver Erkenntnis zu formulieren. Sofern man wissenschaftlicher Erkenntnis Objektivität zugesteht, bleibt jedoch die Frage nach dem synthetischen Apriori aktuell. Das vorliegende Buch will einerseits den historischen Wurzeln sowie verschiedenen Interpretationen des synthetischen Apriori nachspüren und andererseits nach Ansätzen für eine zeitgemäße Reinterpretation dieses fundamentalen Begriffes fragen.

On rationalist infallibilism, a wide range of both (i) analytic and (ii) synthetic a priori propositions can be infallibly justified, i.e., justified in a way that is truth-entailing. In this paper, I examine the second thesis of rationalist infallibilism, what might be called ‘synthetic a priori infallibilism’. Exploring the seemingly only potentially plausible species of synthetic a priori infallibility, I reject the infallible justification of so-called self-justifying propositions.

Peirce did not achieve a final systematization of his work. Beyond the difficulties in explaining so many philosophical tools that he introduced—suffice it to mention semiotic, abductive logic, a heuristic based on continuity, scholastic realism—, there is a theoretical reason for this incompletion. All those new philosophical tools indicated a conception of synthesis very different from the one he received from Kant. Peirce did not realize the profound direction of his enquiry so that he did not directly question neither Kant’s (...) legacy on this issue nor the idea of necessity that presides over it. Starting from Peirce’s conception of continuity and change, this paper will give a new definition of synthetic and analytic judgments and reasoning, completing the picture with a third “vague” judgment and reasoning. In this new definition a synthetic judgment is a judgment that recognizes identity through changes. An analytical judgment is a judgment that loses identity through changes. A vague judgment is a judgment that it is blind to identity through changes. How do we perform synthetic reasoning? Following Peirce’s semiotic study of elements of Gamma Graphs as the sheet of assertion and the line of identity, the paper will first individuate the semiotic characteristics necessary for the recognition of identity. These characteristics lead us to discover “complete gesture” as the tool that we use in our every-day reasoning in order to acquire new knowledge synthetically. “Complete gestures” are actions through which we carry and recognize significant meanings. This new paradigm should provide an improved account of common-sense knowledge as well as of particular creative and hypothetic stages of conception in both scientific and humanistic thought.

Amongst the entities making up social reality, are there necessary relations whose necessity is not a mere reflection of the logical connections between corresponding concepts? We distinguish three main groups of answers to this question, associated with Hume and Adolf Reinach at opposite extremes, and with Searle who occupies a position somewhere in the middle. We first set forth Reinach’s views on what he calls ‘material necessities’ in the realm of social entities. We then attempt to show that Searle has (...) not identified a sustainable position somewhere between the Humean and the Reinachian extremes. This is because Searle’s position is threatened by circularity, and to steer clear of that danger it must incorporate at least some elements of Reinach’s essentialism. (shrink)

This paper considers the question whether the notion of the relative apriori, central to Michael Friedman’s transcendentalist programme for philosophy of science, is available also to philosophers who reject appeals to a synthetic a priori. After tracing the rediscovery of the relative a priori and delineating its potential, the question is considered whether Friedman’s arguments against Quinean naturalism and Carnap’s attenuated logicism tell against a conception of philosophy as scientific metatheory that combines logical and empirical inquiries. Finding an opening here (...) it is argued that this conception can also help itself to the notion of a relative a priori which, it is agreed, is central to historically informed theorising about science.

Subjectivists, taking the “collapse” of the observation-interpretation contrast much too seriously, are led to imagine that even perceptual knowledge is active. And therefore subject dependent. Turning the tables on this popular trend, I argue that even conceptual knowledge is passive. Kant’s epistemology is conceptual. But if also active, then incoherent. If synthetic a priori truths are to follow upon our mental activity, they were neither true nor, far less, a priori before that activity. “A priori” and “active” are contradictory attributes (...) of knowledge. As, indeed, are “a priori” and “subject-dependent” to begin with. Nothing a priori can be dependent on anything except itself, and least of all on the human subject. Kant does consider the active aspect of thought. The difference is that for him the more active it becomes, the less it is to be trusted. For we are no longer in the province of the Understanding, and its necessary truths, but in the realm of Pure Reason and its dialectical antinomies. Cognition activists who take a liking to Kant have simply mistaken Reason for the Understanding. And Reason is to Kant “the seat of all transcendental illusion”. (shrink)

This article sketches out the key features of the debate on the analytic-synthetic distinction between phenomenology and logical empiricism, which took place in the early part of the twentieth century. On the one side, the author reconstructs the debate itself from an historical angle; on the other, he gives a theoretical account of the different positions and arguments. In particular, he has three main aims: a) to clarify how, according to Husserl, the analyticsynthetic opposition is to be understood as the (...) form-matter opposition; b) to show how this position has been misunderstood by neo-empiricist philosophers, in particular by Schlick in his paper against the theory of the factual a priori; c) to point out that Husserlian theory anticipates some relevant features in the matter of analyticity which will be made fully explicit only by Carnap and Quine, philosophers of the following generation.

Abstract: This article contends that the relation of early logical empiricism to Kant was more complex than is often assumed. It argues that Reichenbach's early work on Kant and Einstein, entitled The Theory of Relativity and A Priori Knowledge (1920) aimed to transform rather than to oppose Kant's Critique of Pure Reason. One the one hand, I argue that Reichenbach's conception of coordinating principles, derived from Kant's conception of synthetic a priori principles, offers a valuable way of accounting for the (...) historicity of scientific paradigms. On the other hand, I show that even Reichenbach, in line with Neo-Kantianism, associated Kant's view of synthetic a priori principles too closely with Newtonian physics and, consequently, overestimated the difference between Kant's philosophy and his own. This is even more so, I point out, in the retrospective account logical empiricism presented of its own history. Whereas contemporary reconstructions of this history, including Michael Friedman's, tend to endorse this account, I offer an interpretation of Kant's conception of a priori principles that contrasts with the one put forward by both Neo-Kantianism and logical empiricism. On this basis, I re-examine the early Reichenbach's effort to accommodate these principles to the paradigm forged by Einstein. (shrink)

Hans Reichenbach is well known for his limiting frequency view of probability, with his most thorough account given in The Theory of Probability in 1935/1949. Perhaps less known are Reichenbach's early views on probability and its epistemology. In his doctoral thesis from 1915, Reichenbach espouses a Kantian view of probability, where the convergence limit of an empirical frequency distribution is guaranteed to exist thanks to the synthetic a priori principle of lawful distribution. Reichenbach claims to have given a purely objective (...) account of probability, while integrating the concept into a more general philosophical and epistemological framework. A brief synopsis of Reichenbach's thesis and a critical analysis of the problematic steps of his argument will show that the roots of many of his most influential insights on probability and causality can be found in this early work.

On rationalist infallibilism, a wide range of both (i) analytic and (ii) synthetic a priori propositions can be infallibly justified (or absolutely warranted), i.e., justified to a degree that entails their truth and precludes their falsity. Though rationalist infallibilism is indisputably running its course, adherence to at least one of the two species of infallible a priori justification refuses to disappear from mainstream epistemology. Among others, Putnam (1978) still professes the a priori infallibility of some category (i) propositions, while Burge (...) (1986, 1988, 1996) and Lewis (1996) have recently affirmed the a priori infallibility of some category (ii) propositions. In this paper, I take aim at rationalist infallibilism by calling into question the a priori infallibility of both analytic and synthetic propositions. The upshot will be twofold: first, rationalist infallibilism unsurprisingly emerges as a defective epistemological doctrine, and second, more importantly, the case for the a priori infallibility of one or both categories of propositions turns out to lack cogency.

The article adumbrates the opposition between Aristotelian “metaphysical” meaning of the concept of substance and its critical relational meaning, strongly accentuated by the Marburg Neokantian School. Th is opposition was creatively developed by the aforementioned School. It starts with a critique of Aristotle and his concept of the “substance as being in itself” and proceeds to demonstrate with the reference to the Kantian transcendentalism that concept of the “substance as function” is one of the a priori rules of synthetic cognition. (...) In the Marburg School, the history of the development of these two meanings takes the form of a history of two opposing directions of the thought: dogmatic philosophy – leaning toward the former meaning, and critical – based on the latter.

In this paper I argue that Michael Friedman's conception of the contitutive a priori faces two serious problems. These two problems show that the view collapses into a form of conventionalism.

The distinction between a priori and a posteriori knowledge has been the subject of an enormous amount of discussion, but the literature is biased against recognizing the intimate relationship between these forms of knowledge. For instance, it seems to be almost impossible to find a sample of pure a priori or a posteriori knowledge. In this paper, it will be suggested that distinguishing between a priori and a posteriori is more problematic than is often suggested, and that a priori and (...) a posteriori resources are in fact used in parallel. We will define this relationship between a priori and a posteriori knowledge as the bootstrapping relationship. As we will see, this relationship gives us reasons to seek for an altogether novel definition of a priori and a posteriori knowledge. Specifically, we will have to analyse the relationship between a priori knowledge and a priori reasoning , and it will be suggested that the latter serves as a more promising starting point for the analysis of aprioricity. We will also analyse a number of examples from the natural sciences and consider the role of a priori reasoning in these examples. The focus of this paper is the analysis of the concepts of a priori and a posteriori knowledge rather than the epistemic domain of a posteriori and a priori justification. (shrink)

Intuitively, it seems that some belief-forming practices have the following three properties: 1. They are rational practices, and the beliefs that we form by means of these practices are themselves rational or justified beliefs. 2. Even if in most cases these practices reliably lead to correct beliefs (i.e., beliefs in true propositions), they are not infallible: it is possible for beliefs that are formed by means of these practices to be incorrect (i.e., to be beliefs in false propositions). 3. The (...) rationality of these practices is basic or primitive. That is, the rationality of these practices is not due simply to the availability, by means of some process of reasoning that relies purely on other practices, of a rational or justified belief in the reliability of these practices. -/- How can there be such practices? This paper offers an answer to that question. (shrink)

Kant's original version of transcendental philosophy took both Euclidean geometry and the Newtonian laws of motion to be synthetic a priori constitutive principles—which, from Kant's point of view, function as necessary presuppositions for applying our fundamental concepts of space, time, matter, and motion to our sensible experience of the natural world. Although Kant had very good reasons to view the principles in question as having such a constitutively a priori role, we now know, in the wake of Einstein's work, that (...) they are not in fact a priori in the stronger sense of being fixed necessary conditions for all human experience in general, eternally valid once and for all. And it is for precisely this reason that Kant's original version of transcendental philosophy must now be either rejected entirely or radically reconceived. Most philosophy of science since Einstein has taken the former route: the dominant view in logical empiricism, for example, was that the Kantian synthetic a priori had to be rejected once and for all in the light of the general theory of relativity.

The article approaches Salomon Maimon’s reinterpretation of the notions of the thing in itself and the given within the framework of criticism. For Maimon they do not refer to a transcendence that is directly unattainable by knowledge. In this attempt, he tries to explain the given on the basis of the action of constitutive understanding. With this, he triggers the passage from transcendental Kantian philosophy to the idealism of Fichte. Nonetheless, his position faces the subsequent problem of explaining how the (...) constitution of the given from understanding (infinite) can become compatible with the criticism it takes on. On affirming that an uncognoscible item is the basis of knowledge, namely, infinite understanding, he set aside the explanation of knowledge in terms of what is revealed in it and in doing so would be resorting to external uncognoscible conditions.

The aim of this article is to reconstruct the State law Kantian theory exposed in Rechtslehre , through an analytical-logical reading key, which contains as proof proceeding the analysis and synthesis method. This investigation corroborates with the interpretation that defends the criticality this late juridical text to an extent that the State law is connected to the critical plan of the a priori synthetic judgments in general enunciation.

In the horizon of the Kantian theory of the reasoning problems and his auxiliary theory , can the States law fundamental juridical problem in Rechtslehre be synthesized by the question: how are the States law a priori synthetic judgments possible? On the other hand, in the matter of logical-analytical problems resolution, it is possible to operate through the analysis and synthesis method. The objective of this article is to reconstruct the possibility problem and the applicability of the States law theory (...) according to this procedure of discovery and exposition. In a wide context, the aim is to connect the Kantian Rechtslehre to the solubility theory of reasoning in general to make explicit the critical character of this late juridical work. (shrink)

Abstract: This article explains and motivates an account of one way in which we might have substantive a priori knowledge in one important class of domains: domains in which the central concepts are response-dependent. The central example will be our knowledge of the connection between something's being harmful and the fact that it is irrational for us to fail to be averse to that thing. The idea is that although the relevant responses (basic aversion in the case of harm, and (...) a kind of interpretive failure in the case of irrationality) are produced by independent psychological mechanisms, they have distal causes that turn out to be related in ways that—once language enters the picture—yield epistemically accessible necessary connections between the referents of their corresponding terms.

In twentieth-century Kant scholarship, few have provided an account of the analytic-synthetic distinction and of the problem of the synthetic a priori that takes into consideration the views of Kant's idealist successors such as Maimon, Fichte, Schelling, and Hegel. I first explain how Kant formulates the analytic-synthetic distinction in terms of the determinate-indeterminate distinction, which, in turn, is based on the distinction between general and transcendental logic. Kant's problem of the synthetic a priori , then, is the problem of showing (...) how the logical forms of judgment can be employed determinately (and not merely indeterminately). I then show that Maimon also formulates the distinction and the problem in the same way, and that his interpretation will shape how Fichte, Schelling, and Hegel each construe and address Kant's question, How are synthetic judgments possible a priori ?

Kant famously thought that mathematics contains synthetic a priori truths. In his book, Wille defends a version of the Kantian thesis on not-so-Kantian grounds. Wille calls his account neo-Kantian, because it makes sense of Kantian tenets by using a methodology that takes the linguistic and pragmatic turns seriously.Wille's work forms part of a larger project in which the statuses of mathematics and proof theory are investigated. The official purpose of the present book is to answer the question: what is mathematics. (...) Wille sets himself the task of finding a definition that enables him to distinguish between mathematics and proof theory. His solution reads roughly as follows. Mathematics is about how to generate synthetic a priori knowledge by acting within some calculus. This definition does not seem to be a promising starting point, because in this way a very controversial claim becomes true by definition. However, Wille's strategy is to make sense of his definition during the course of his argument and to show that the definition is appropriate regarding research that is commonly taken to be mathematics.The second part of the book explains what ‘acting within some calculus’ amounts to. In Wille's view, mathematics should be characterized in …. (shrink)

El problema fundamental para que la Teoría de la relatividad pueda ser acorde con la filosofía de Kant es el de la utilización de una geometría no euclídea. Que sus principios sean interpretados como juicios sintéticos a priori es, a nuestro entender, un problema secundario. Si queremos que los principios de una ciencia de la naturaleza sean universales y necesarios sin recurrir a dogmatismos, no queda otra posibilidad que entenderlos trascendentalmente. Como se observa en el principio de relatividad, Einstein también (...) pensaba que las leyes físicas son universales y necesarias. Sin embargo, su perspectiva fue más racionalista que crítica. Sea como fuere, si los principios de la Teoría de la relatividad son a priori y enlazan sintéticamente la experiencia posible, esta teoría nos servirá para entender que las geometrías no euclídeas no son ajenas a los planteamientos de Kant, si bien requieren dar un rodeo epistemológico. La doctrina que nos permite fundamentar las geometrías no euclidianas desde la filosofía de Kant la llamamos “Álgebra de la experiencia”.The main problem for the Theory of the relativity to be in agreement with the Kant´s philosophy is the use of a non-Euclidean geometry. The fact that their principles could be interpreted a priori as synthetic trials is, in our opinion, a secondary problem. If we want that the principles of a science of the nature would be universal and necessary ones without appealing to dogmatisms, then, he have to understand them transcendentally. As in the principle of relativity it is observed, Einstein also thought that the physical laws are universal and necessary ones. However, their perspective was more rationalistic than critic. In any case, if the Theory of Relativity principles are a priori and they synthetically connect the possible experience, then, this theory will allow us to understand that the non-Euclidean geometries are not far away from the Kant´s positions, although they require to made a epistemological turn around. The principle that allows us to base the geometries non Euclidian from the Kant´s philosophy is called “Algebra of the experience”. (shrink)

Kant’s analytic-synthetic distinction is often construed in terms of the question of whether or not the predicate is contained in or can be derived from the concept of the subject. Few have observed that Kant has another formulation of the distinction, a formulation that is based on the determinate-indeterminate distinction. In fact, it is this formulation that will shape the development of one of the main tasks of post-Kantian German idealism. It is my aim to explain how Kant, Maimon, and (...) Fichte each define and address the problem of the synthetic a priori in terms of the determinate-indeterminate distinction. (shrink)

The explanation of the nature and way of construction of these last ones will show that Kant was characterizing a procedure common in the science of the XVIII century, and that today it can still be read in the standard scientific practice.
