It is widely claimed that the second Critique’s argument for the postulate of immortality is relevantly different from the first Critique’s argument for the postulate. It is also widely claimed that after the second Critique, Kant distances himself from its particular version of the argument, and even the postulate altogether. It is the purpose of this article to challenge these claims, arguing instead that (a) there is overwhelming textual evidence showing that Kant did not abandon the postulate; (b) the second (...) Critique does not contain a substantially different argument for the postulate than how it is argued for in the first Critique; and (c) the philosophical objections levied against the second Critique’s argument, including its putative substitution of holiness for virtue, become moot once its argument is better understood.

The qualitative theory of nomic truth approximation, presented in Kuipers in his, in which ‘the truth’ concerns the distinction between nomic, e.g. physical, possibilities and impossibilities, rests on a very restrictive assumption, viz. that theories always claim to characterize the boundary between nomic possibilities and impossibilities. Fully recognizing two different functions of theories, viz. excluding and representing, this paper drops this assumption by conceiving theories in development as tuples of postulates and models, where the postulates claim to exclude (...) nomic impossibilities and the models claim to represent nomic possibilities. Revising theories becomes then a matter of adding or revising models and/or postulates in the light of increasing evidence, captured by a special kind of theories, viz. ‘data-theories’. Under the assumption that the data-theory is true, achieving empirical progress in this way provides good reasons for the abductive conclusion that truth approximation has been achieved as well. Here, the notions of truth approximation and empirical progress are formally direct generalizations of the earlier ones. However, truth approximation is now explicitly defined in terms of increasing truth-content and decreasing falsity-content of theories, whereas empirical progress is defined in terms of lasting increased accepted and decreased rejected content in the light of increasing evidence. These definitions are strongly inspired by a paper of Gustavo Cevolani, Vincenzo Crupi and Roberto Festa, viz., “Verisimilitude and belief change for conjunctive theories” :183–222, 2011). (shrink)

The aim of interpretation is to capture the past in the future: to capture, not to recapture, first, because the iterative prefix suggests that meaning, which was once manifest, must now be found again. But the postulated author dispenses with this assumption. Literary texts are produced by very complicated actions, while the significance of even our simplest acts is often far from clear. Parts of the meaning of a text may become clear only because of developments occurring long after its (...) composition. And though the fact that an author means something may be equivalent to the fact that a writer could have meant it, this is not to say that the writer did, on whatever level, actually mean it.Alexander Nehamas, professor of philosophy at the University of Pittsburgh, has written articles on ancient Greek philosophy, literary theory, Nietzsche and Thomas Mann.

We present a quantum mechanical analysis of Bell’s approach to quantum foundations based on his hidden-variable model. We claim and try to justify that the Bell model contradicts to the Heinsenberg’s uncertainty and Bohr’s complementarity principles. The aim of this note is to point to the physical seed of the aforementioned principles. This is the Bohr’s quantum postulate: the existence of indivisible quantum of action given by the Planck constant h. By contradicting these basic principles of QM, Bell’s model implies (...) rejection of this postulate as well. Thus, this hidden-variable model contradicts not only the QM-formalism, but also the fundamental feature of the quantum world discovered by Planck. (shrink)

The postulates of rational preference suggested by Von Neumann and Morgenstern have been defended as descriptive or empirical generalizations and as normative principles. It is argued that the postulates are inaccurate empirical generalizations and unacceptable normative principles.

This article outlines the work of a group of US mathematicians called the American Postulate Theorists and their influence on Tarski's work in the 1930s that was to be foundational for model theory. The American Postulate Theorists were influenced by the European foundational work of the period around 1900, such as that of Peano and Hilbert. In the period roughly from 1900???1940, they developed an indigenous American approach to foundational investigations. This made use of interpretations of precisely formulated axiomatic theories (...) to prove such metatheoretic properties as independence, consistency, categoricity and, in some cases, completeness of axiom sets. This approach to foundations was in many respects similar to that later taken by Tarski, who frequently cites the work of American Postulate Theorists. Their work served as paradigm examples of the theories and concepts investigated in model theory. The article also examines the possibility of a more specific impetus to Tarski's model theoretic investigation, arising from his having studied in 1927???1929 a paper by C. H. Langford proving completeness for various axiom sets for linear orders. This used the method of elimination of quantifiers. The article concludes with an examination of one example of Langford's methods to indicate how their correct formulation seems to call for model-theoretic concepts. (shrink)

Kant's noncognitive argument based on practical reason claims that moral considerations alone suffice to justify the idea of personal immortality as a postulate. Some recent objections are considered here that have charged him with overstepping his own distinction between phenomenon and noumenon. After examining the arguments, Kant is exonerated of having violated his own principles. More troubling, however, is the peculiarity involved in postulating an infinite progression toward a goal whose attainment, by hypothesis, would undermine the very foundations of morality (...) (which for Kant always requires the agonistic condition of struggling to improve one's lower nature). It is argued that this paradox necessitates a reexamination of some tacit cultural presuppositions underlying Kant's conception of the soul. Finally, an examination is made of the thought of Kitarō Nishida, whose Zen Buddhist–inspired dialectic of the basho (logical "place") provides an alternative perspective from which to reconsider the postulate of immortality. Nishida, like Kant, rigorously maintains the phenomenonnoumenon distinction, yet his examination of ethics leads him to postulate an eventual sublation of the "soul" principle. It is concluded that Kant's postulate of immortality, while plausible enough on its own terms, is limited by a Western cultural bias and therefore fails in the end to be compelling. (shrink)

A detailed list of postulates is formulated in an algebraic setting. These postulates are sufficient to entail the standard time evolution governed by the Schrödinger or Dirac equation. They are also necessary in a strong sense: Dropping any one of the postulates allows for other types of time evolution, as is demonstrated with examples. Some philosophical remarks hint on possible further investigations.

Das Buch enthält die Einführung in die Lektüre sowie den Textkommentar zu den der Analyse der Grundsätze der Modalität gewidmeten "Postulaten des empirischen Denkens überhaupt". Untersucht wird Kants gesamte Theorie der Modalbegriffe (Möglichkeit - Unmöglichkeit, Dasein - Nichtsein, Notwendigkeit - Zufälligkeit) seit Mitte der 1750er Jahre bis zur Kritik der reinen Vernunft. Die Postulate sind nach Kant nicht objektiv, sondern subjektiv-synthetisch: Der Gegenstand der Erfahrung, welcher zunächst anhand der objektiv-synthetischen Funktionen der Quantität, Qualität und Relation bestimmt wird, lässt sich nun (...) in seinem Verhältnis zum setzenden Subjekt betrachten. Die Postulate thematisieren jedoch nicht - hier liegt die konstitutive Charakteristik dieser synthetischen Urteile a priori - das Subjekt selbst, sondern das Objekt als solches und die Objektivität überhaupt. Wie diese Untersuchung zeigt, antwortet Kant erst hier - nicht in den viel diskutierten Deduktionskapiteln oder in den anderen Grundsatzkapiteln - auf die Frage "Was ist ein Objekt?" und bezieht zugleich Stellung gegenüber anderen philosophischen Theorien der Objektivität des 18. Jahrhunderts: Rationalismus, Empirismus, Idealismus, Skeptizismus. (shrink)

The pessimistic induction and the problem of underdetermination in the philosophy of science have a rich history. In their recent incarnation as the problem of unconceived alternatives, most fully articulated by Kyle Stanford (2010) in Exceeding Our Grasp, the induction is more specific and underdetermination is construed more epistemically than is typical…The problem is not that there are empirically equivalent alternatives, that is, alternative between which no empirical evidence could ever distinguish. The problem is that multiple radically different alternative that (...) are empirically inequivalent might be equally well-confirmed by current evidence, and we might fail to even conceive one or more of those alternatives… In “Of German Tanks and Scientific Theories: Estimating the Number of Unconceived Alternatives,” Burkay Ozturk (2016) challenges Stanford on a distinct front. By applying a method of statistical estimation to scientific alternatives, Ozturk argues that the possibility space within which the alternatives are located allows for probable knowledge. The particular frequentist estimation method Ozturk employs requires that we assume the alternative pool is finite, which seems to be both false and wildly implausible. At first glance. I argue in this comment that Ozturk’s postulate of finitude is actually defensible in circumstances that might actually hold for ordinary scientific contexts. (shrink)

In Prior’s [4], Appendix A §4 and §5, and Chapter IV, and more explicitly in Bull’s [2], we find sequences of tense-logical systems which place increasingly more restrictive conditions on the temporal relation “… is before …”. We give here a simple, diagrammatic account of the way in which the successive postulates for temporal order place these conditions on the temporal relation: we do not provide any essentially new semantics for these systems, nor do we prove any rigorous metatheorems. (...) We do, however, quite often assume the completeness results of Lemmon, Bull and others without explicit mention. (shrink)

Sufficient texts show that for aristotle the universal notion expresses the same real thing as the particular, Though in a different way. His grounds for a universal so conceived are twofold. First, In every sensible thing there is a basic formal principle that, Though individual, Brings each instance into formal identity with all the other instances. Secondly, In human intellectual cognition there is an active principle that raises knowledge above the status of photographing or registering or cataloguing, And actualizes what (...) was only potential in the real thing. In knowing sensible things universally, The human intellect is able to grasp the concrete thing as characterized by a formal nature, Thereby knowing it in a way that holds equally for all other instances. Though patently incomplete, This conception of the universal is free from internal contradictions. It provides a framework for fruitful discussion, And remains a challenge. (shrink)

Most philosophers of science nowadays hold a network or postulational view of the meaning of theoretical words. However, there are many nuances to this view, and after explicitly separating them, we show what we take to be wrong with each one. While we reject the postulational view we do not defend its traditional alternatives either; rather we show the pointlessness of insisting on a single source for the meaning of theoretical words. We also point out the shortcomings of Carnap's newest (...) meaning criterion which depends upon a network view. But, again, we suggest not only that this new rendition of the criterion is faulty but also that there is something misguided about any search at all for such a criterion. (shrink)

This paper explores an analogy between two approaches to teleology in nature and two theories of authorship. I argue that Spinoza’s attempt (as Kant criticizes it in the Third Critique) to explain all natural unity, and explain away apparent teleological unity, in terms of inhering in the same subject (God) or proceeding causally from God’s essence mirrors the view Proust lays out in the essay “Gustave Moreau” that the features of a work of art are unified in virtue of occurring (...) together in, and proceeding from the laws of, the artist’s inner soul. Meanwhile, the strategy Kant favors for understanding interdependent natural systems like organisms—provisionally considering them as purposively designed—resembles the one Alexander Nehamas recommends in “The Postulated Author” (1981) for interpreting a work of art: imagining the agent who could have intended all its features. I propose that this analogy sheds light on the unity of the two parts of the Third Critique by pointing to the similarity between interpreting beautiful objects and interpreting nature. (shrink)

A reproducibility principle is formulated and adopted as the guiding criterion for the acceptance of an experimental procedure as a simultaneous measurement of several observables. It is pointed out that this criterion can be applied to classical as well as quantum physics, and that it incorporates compatible as well as incompatible observables. The concept of fuzzy probability measure is presented as a possible mathematical tool for the description of statistical processes involving measurements of incompatible observables.

Erwin Panofsky developed the postulate of clarification to explain the mental habit common to Gothic architecture and Western medieval scholasticism, but the postulate is equally applicable to the commentary tradition of Song-dynasty China. The commentary on the Book of Changes authored by Cheng Yi (1033–1107) provides a good example of how the Confucians of the Song dynasty took their concern for clarity to a recognizably medieval extreme. By looking at how Cheng Yi understands and foregrounds the clarity of the Book (...) of Changes, we can begin to see both what was medieval about Song-dynasty China and why the medieval method continues to be viable for interpreters of the Book of Changes.

In the paper I analyze two features of the genre of the pedagogical. First is a particular usage of “should” statements where one can identify an effect of erasing present normative behavior, while that which is postulated is turned into an unattainable ideal, or a value. Second, I analyze “presumptive tautologies” in the discourse of aims of education. I focus on negative dimensions of these two features and, using theoretical insights from Laclau and Rancière, I connect them to the work (...) of negativity in political ontology so that the relation between the pedagogical and the political can thus be re-articulated.

I consider how procedural postulationism might be combined with the view that postulational possibility should itself be open to expansion.

Although the subjective expected utility (SEU) theory is more than 60 years old, it was recently discovered by Hartmann (Econometrica 88(1):203–205, 2020, https://doi.org/10.3982/ECTA17428) that one of the original seven postulates is redundant, i.e., it is implied by the other six postulates. In this brief communication, we show that this redundant axiom is the only one that is implied by the other axioms, thereby establishing that the remaining six postulates form an independent axiomatic system. This result further streamlines (...) the preference assumptions underlying the SEU theory. (shrink)

We propose to take issue with a neo-behaviorist upon what might seem to be a minor detail, and about which we are sure that, upon reflection, he would not differ from us. It has to do with the use of the word experience in a basic postulate of behaviorism. Even if by a hair's breadth this implies something categorically different from behavior, then, it seems to us, the essential meaning of behaviorism has been missed.

Fodor (1998) argues that most lexical concepts have no internal structure. He rejects what he calls Inferential Role Semantics (IRS), the view that primitive concepts are constituted by their inferential relations, on the grounds that this violates the compositionality constraint and leads to an unacceptable form of holism. In rejecting IRS, Fodor must also reject meaning postulates. I argue, contra Fodor, that meaning postulates must be retained, but that when suitably constrained they are not susceptible to his arguments (...) against IRS. This has important implications for the view that certain of our concepts are deferential. A consequence of the arguments I present is that deference is relegated to a relatively minor role in what Sperber (1997) refers to as reflective concepts; deference has no important role to play in the vast majority of our intuitive concepts.

In the first part of this article we will formulate postulates, which must be satisfied by a reasonable concept of emergence. The postulates will articulate conditions of adequacy for an appropriate explication of the concept of emergence. These conditions of adequacy are based primarily upon the philosophical and scientific history of the concept of emergence, in which the intended role of the concept is expressed. In the second part we will discuss and evaluate some candidates for the concept (...) of emergence in light of these conditions of adequacy. (shrink)

How did life come into existence on Earth? Although many scientific theories and hypotheses have been drawn, we have not yet been able to provide a detailed answer to this fundamental question. What if intelligent computers would someday be in a condition to postulate their own evolution theory which would explain how they came into the world, how would this theory look like? And how would it stand in comparison to the humans’ theory? Let us suppose that a thousand years (...) from now, intelligent and self-aware computers who, for any reason whatsoever, had lost all contacts with humans, and had continued to self-develop and improve by themselves, slowly began to wonder about how they came into the world? These intelligent computers may eventually develop a coherent theory of evolution, which would seemingly explain their existence. How would their theory stand in comparison to our theory of evolution? Would it be less comprehensive or viable? Taking into consideration the inorganic nature of computers, their relative simplicity compared to the human body, and the closeness of their components to the surrounding inorganic environment, it would not be a surprise if their theory would be more plausible than that of the humans. So, what would this signify and mean to our scientific theories in general? (shrink)

This paper presents four theorems that connect continuity postulates in mathematical economics to solvability axioms in mathematical psychology, and ranks them under alternative supplementary assumptions. Theorem 1 connects notions of continuity (full, separate, Wold, weak Wold, Archimedean, mixture) with those of solvability (restricted, unrestricted) under the completeness and transitivity of a binary relation. Theorem 2 uses the primitive notion of a separately continuous function to answer the question when an analogous property on a relation is fully continuous. Theorem 3 (...) provides a portmanteau theorem on the equivalence between restricted solvability and various notions of continuity under weak monotonicity. Finally, Theorem 4 presents a variant of Theorem 3 that follows Theorem 1 in dispensing with the dimensionality requirement and in providing partial equivalences between solvability and continuity notions. These theorems are motivated for their potential use in representation theorems. (shrink)

The device of setting forth an argument in the form of a postulate set, while not unknown to jurisprudence, is nevertheless sufficiently novel to justify a brief account of the process. At one time human thought took axioms and postulates for avowals of unalterable truth, but the nineteenth century made common the practice of speculating with alternative presuppositional systems, so that deeper insight into the nature of this scientific device revealed it as merely a method among many for clarifying (...) and fecundating thought.

It was Heine who cynically suggested that Kant introduced the postulates of practical reason to comfort his manservant Lampe. Kant's view of morality is teleological, in that it sees obedience to the moral law as, at the same time, the fulfilment of human perfection. The legislation of the moral law which man himself creates is the true expression of man's autonomy and superiority over the sensuous bounds nature has set him. It is in such legislation that he begins to (...) realise his transcendentally free nature and fulfil himself as a distinctively human person. The law of duty is thus known, practically, as supremely authoritative. An intelligible ethical theory can certainly be extracted from the Kantian metaphysical context. Indeed, his doctrine is so complex that a number of alternative methods of demythologisation present themselves, depending largely upon the interests of the interpreter. (shrink)

In the Critique of Pure Reason, following his elucidation of the ‘postulates’ of possibility, actuality, and necessity, Kant makes a series of puzzling remarks. He seems to deny the somewhat metaphysically intuitive contention that the extension of possibility is greater than that of actuality, which, in turn, is greater than that of necessity. Further, he states that the actual adds nothing to the possible. This leads to the view, fairly common in the literature, that Kant holds that all modal (...) categories, in their empirical applications, are coextensive. I diverge from the common view. First, Kant is not committed to the coextensiveness thesis, understood as above. Instead, he espouses a weaker, epistemological version of the coextensiveness thesis, namely that what we can assert to be really possible is coextensive with what we cognize to be actual. Second, Kant's remarks are not intended to introduce a positive ontological thesis about the extensions of modal categories. Rather, he means to criticize a certain conception of modalities that was prevalent among his rationalist predecessors, i.e., the conception of modalities as various determinations that enter the intensions of concepts of things.
