It is plausible to think that, in order to actively employ models in their inquiries, scientists should be aware of their existence. The question is especially puzzling for realists in the case of abstract models, since it is not obvious how this is possible. Interestingly, though, this question has drawn little attention in the relevant literature. Perhaps the most obvious choice for a realist is appealing to intuition. In this paper, I argue that if scientific models were (...) class='Hi'>abstract entities, one could not be aware of them intuitively. I deploy my argumentation by building on Chudnoff’s elaboration on intuitive awareness. Furthermore, I shortly discuss some other options to which realists could turn in order to address the question of awareness. (shrink)

Peano's axiomatizations of geometry are abstract and non-intuitive in character, whereas Peano stresses his appeal to concrete spatial intuition in the choice of the axioms. This poses the problem of understanding the interrelationship between abstraction and intuition in his geometrical works. In this article I argue that axiomatization is, for Peano, a methodology to restructure geometry and isolate its organizing principles. The restructuring produces a more abstract presentation of geometry, which does not contradict its intuitive content (...) but only puts it into a particular form. (shrink)

RésuméLa qualité essentielle d'un mathématicien est l'imagination; la logique ne sert qu'à mettre les démonstrations sous une forme irréfutable, elle est incapable de les suggérer. L'imagination se fonde sur une sorte d'« intuition » des objets mathématiques étudiés, mais cela n'a que très peu de contact avec ce qu'on appelle d'ordinaire l'« intuition » sensible, les objets mathématiques considérés étant le plus souvent l'aboutissement d'un long processus d'abstraction qui leur ǒte toute possibilité de représentation concrète. Cette « (...) class='Hi'>intuition » mathématique est avant tout le résultat d'une longue familiarité avec le sujet étudié; mais en outre il peut s'opérer des « transferts » d'intuition d'une théorie dans une autre; on en donne quelques exemples qui font ressortir la fécondité de tels transferts.

Experimental philosophers have disagreed about whether "the folk" are intuitively incompatibilists or compatibilists, and they have disagreed about the role of abstraction in generating such intuitions. New experimental evidence using Construal Level Theory is presented. The experiments support the views that the folk are intuitively both incompatibilists and compatibilists, and that abstract mental representations do shift intuitions, but not in a univocal way.

What are intuitions? According to doxastic views, they are doxastic attitudes or dispositions, such as judgments or inclinations to make judgments. According to perceptualist views, they are—like perceptual experiences—pre-doxastic experiences that—unlike perceptual experiences—represent abstract matters as being a certain way. In this paper I argue against doxasticism and in favor of perceptualism. I describe two features that militate against doxasticist views of perception itself: perception is belief-independent and perception is presentational. Then I argue that intuitions also have both features. (...) The upshot is that intuitions are importantly similar to perceptual experiences, and so should not be identified with doxastic attitudes or dispositions. I consider a popular argument from the introspective absence of sui generis intuition experiences in favor of doxasticism. I develop a conception of intuition experiences that helps to defuse this argument. (shrink)

Elijah Chudnoff elaborates and defends a view of intuition according to which intuition purports to, and reveals, how matters stand in abstract reality by making us aware of that reality through the intellect. He explores the experience of having an intuition; justification for beliefs that derives from intuition; and contact with abstract reality.

How should we understand intuitive cognition? Duns Scotus held that we have intuitive cognition only when objects cause our knowledge without any causal intermediary; if an intelligible species caused our knowledge, it would be abstractive cognition. Compared to abstractive cognition, intuitive cognition is the paradigmatic case of knowledge; by contrast, abstractive cognition is only a "second best.".

This paper sketches an account that explains the elusive subjective quality of 'enduring substantiality' of the phenomenal self. It integrates a recent predictive processing account of the self by Chris Letheby and Philip Gerrans with key ideas of Michael Graziano's attention schema theory of consciousness. Similarly to the attention schema theory, the present account posits an internal model of ongoing attentional processing that supports attentional control. In terms of predictive processing, it is a dynamic model of precision estimates that represents (...) the salience of features, objects, and internal and external processes. The apparent substantiality of the self is then explained by a structural feature of this salience model: it binds different dimensions of salience by representations of higher-order dimensions of salience. The result of this salience binding is a phenomenally transparent 'salience object', which is represented as a cause of widespread changes in precision estimates, and results in a form of epistemic self-control. Phenomenologically, this goes along with the experience of the self as an attentional agent, and in this way creates the origin of our consciously experienced first-person perspective: I attend, I am.

By all accounts one of the most influential philosophical contributions of Duns Scotus is his distinction between intuitive cognition, in which a thing is known as present and existing, and abstractive cognition, which abstracts from actual presence and existence. Recent scholarship has focused almost exclusively on the role given intuitive cognition in the justification of contingent propositions and on the debates over certitude which arose from the critiques of Scotus's distinction by Peter Aureoli and William of Ockham.

In his influential paper “Grasping the Third Realm,” John Bengson raises the question of how we can non-accidentally grasp abstract facts. What distinguishes successful intuition from hallucinatory intuition? Bengson answers his “non-accidental relation question” by arguing for a constitutive relationship: The intuited object is a literal constituent of the respective intuition. Now, the problem my contribution centers around is that Bengson’s answer cannot be the end of the story. This is because, as Bar Luzon and Preston (...) Werner have recently pointed out, this answer leads to the follow-up question of why certain intuitional experiences are constituted by the facts, but others are not. My objective is to answer this question by specifying precisely what is epistemically defective about intellectual hallucinations. My result is that, in stark contrast to perception, intellectual hallucinations are epistemically defective in the sense that something is overlooked. In successful intuition, by contrast, all relevant possibilities/scenarios are considered/imagined. This has crucial epistemological implications. In particular, I argue that intuitions exhibiting a certain phenomenology cannot fail to successfully grasp abstract facts. I call this the non-accidental correctness thesis, which constitutes the main thesis of this paper. (shrink)

In this paper I assume that we have some intuitive knowledge—i.e. beliefs that amount to knowledge because they are based on intuitions. The question I take up is this: given that some intuition makes a belief based on it amount to knowledge, in virtue of what does it do so? We can ask a similar question about perception. That is: given that some perception makes a belief based on it amount to knowledge, in virtue of what does it do (...) so? A natural idea about perception is that a perception makes a belief amount to knowledge in part by making you sensorily aware of the concrete objects it is about. The analogous idea about intuition is that an intuition makes a belief amount to knowledge in part by making you intellectually aware of the abstract objects it is about. I expand both ideas into fuller accounts of perceptual and intuitive knowledge, explain the main challenge to this sort of account of intuitive knowledge (i.e. the challenge of making sense of intellectual awareness), and develop a response to it.

Many philosophers claim that intuitions are evidential. Yet it is hard to see how introspecting one's mental states could provide evidence for such synthetic truths as those concerning, for example, the abstract and the counterfactual. Such considerations have sometimes been taken to lead to mentalism---the view that philosophy must concern itself only with matters of concept application or other mind-dependent topics suited to a contemplative approach---but this provides us with a poor account of what it is that philosophers take (...) themselves to be doing, for many of them are concerned with the extra-mental facts about the universe. Evidentialism therefore gestates a disaster for philosophy, for it ultimately demands an epistemology for the investigation into such matter as the abstract and the modal that simply will not be forthcoming. We make a different suggestion: That intuitions are inclinations to believe. Hence, according to us, a philosophical argument does well, as a socio-rhetorical matter of fact, when it is founded on premises philosophers are generally inclined to believe, whether or not those inclinations to believe connect appropriately to the extra-mental facts. Accordingly, the role of intuitions (inclinations to believe) in philosophical methodology is non-evidential, and the question of how they could be used as evidence falls away. (shrink)

Charles Parsons’ book “Mathematical Thought and Its Objects” of 2008 (Cambridge University Press, New York) is critically discussed by concentrating on one of Parsons’ main themes: the role of intuition in our understanding of arithmetic (“intuition” in the specific sense of Kant and Hilbert). Parsons argues for a version of structuralism which is restricted by the condition that some paradigmatic structure should be presented that makes clear the actual existence of structures of the necessary sort. Parsons’ paradigmatic structure (...) is the so-called ‘intuitive model’ of arithmetic realized by Hilbert’s strings of strokes. This paper argues that Hilbert’s strings, considered as given in intuition, cannot play the role Parsons assigns to them: the criteria of identity of these strings do not have the sharpness that Parsons wants to see in them, and Parsons inadvertently projects abstract structures into his ‘intuitive model’. This diagnosis is exemplified with respect to (a) Parsons’ distinction between addition and multiplication on the one hand and exponentiation on the other and (b) his analysis of arithmetical knowledge in simple cases like “7 + 5 = 12”. All in all, it is claimed that Parsons book contains many important insights with respect to, for example, different versions structuralism, the notion of “natural number” and its uniqueness, induction, predicativity and other things, for which he is rightly famous, but that his way of drawing on the notion of intuition leaves too many questions unanswered.

ABSTRACT ABSTRACT: This paper provides a multifaceted account of intuition. The paper integrates apparently disparate conceptions of intuition, shows how the notion has figured in epistemology as well as in intuitionistic ethics, and clarifies the relation between the intuitive and the self-evident. Ethical intuitionism is characterized in ways that, in phenomenology, epistemology, and ontology, represent an advance over the position of W. D. Ross while preserving its commonsense normative core and intuitionist character. This requires clarifying the (...) sense in which intuitions are non-inferential and explaining how self-evident principles may be maintained without dogmatism, how intuition is significantly analogous to perception, and how rational disagreements can extend even to the self-evident. The paper distinguishes between two orders of normative disagreement, shows how intuition can contribute to resolving normative disagreements, and represents ethical intuitionism as capable of modified forms that depart from its traditional claims in being neutral with respect to both ethical naturalism and metaphysical realism.

"Intuition" has perhaps been the least understood and the most abused term in philosophy. It is often the term used when one has no plausible explanation for the source of a given belief or opinion. According to some sceptics, it is understood only in terms of what it is not, and it is not any of the better understood means for acquiring knowledge. In mathematics the term has also unfortunately been used in this way. Thus, intuition is sometimes (...) portrayed as if it were the Third Eye, something only mathematical "mystics", like Ramanujan, possess. In mathematics the notion has also been used in a host of other senses: by "intuitive" one might mean informal, or non-rigourous, or visual, or holistic, or incomplete, or perhaps even convincing in spite of lack of proof. My aim in this book is to sweep all of this aside, to argue that there is a perfectly coherent, philosophically respectable notion of mathematical intuition according to which intuition is a condition necessary for mathemati cal knowledge. I shall argue that mathematical intuition is not any special or mysterious kind of faculty, and that it is possible to make progress in the philosophical analysis of this notion. This kind of undertaking has a precedent in the philosophy of Kant. While I shall be mostly developing ideas about intuition due to Edmund Husser! there will be a kind of Kantian argument underlying the entire book. (shrink)

Williams (1970) argues that our intuitions about personal identity vary depending on how a given thought experiment is framed. Some frames lead us to think that persistence of self requires persistence of one's psychological characteristics; other frames lead us to think that the self persists even after the loss of one's distinctive psychological characteristics. The current paper takes an empirical approach to these issues. We find that framing does affect whether or not people judge that persistence of psychological characteristics is (...) required for persistence of self. Open-ended, abstract questions about what is required for survival tend to elicit responses that appeal to the importance of psychological characteristics. This emphasis on psychological characteristics is largely preserved even when participants are exposed to a concrete case that yields conflicting intuitions over whether memory must be preserved in order for a person to persist. Insofar as our philosophical theory of personal identity should be based on our intuitions, the results provide some support for the view that psychological characteristics really are critical for persistence of self.

In the recent literature on causal and non-causal scientific explanations, there is an intuitive assumption according to which an explanation is non-causal by virtue of being abstract. In this context, to be ‘abstract’ means that the explanans in question leaves out many or almost all causal microphysical details of the target system. After motivating this assumption, we argue that the abstractness assumption, in placing the abstract and the causal character of an explanation in tension, is misguided in (...) ways that are independent of which view of causation or causal explanation one takes to be most accurate. On major accounts of causation, as well as on major accounts of causal explanation, the abstractness of an explanation is not sufficient for it being non-causal. That is, explanations are not non-causal by dint of being abstract. (shrink)

이 논문의 목적은 둔스 스코투스의 직관적 인식 개념의 역사적 의미를 설명하는 것이다. 스코투스에 따르면 직관적 인식은 다음의 두 조건이 충족될 때 성립한다. 즉 대상이 실존하며, 대상이 인과적 대리물을 통하지 않고 직접적으로 제시되어야 한다는 것이다. 그리고 추상적 인식이란 두 가지 조건 중 어느 하나를 충족시키지 못하는 인식이다. 스코투스 시대까지 일반적인 관점은, 적어도 현세적 삶에서 추상은 지성의 주요할 뿐 아니라 유일한 작용방식이라는 것이었다. 그러나 스코투스는 추상과 직관의 구별을 감각뿐 아니라 지성적 인식에도 적용되는 구별로 본다. 지성적 직관에 대한 스코투스의 통찰은 중세 개별자 인식의 (...) 문제에 새로운 빛을 던져준다.

Abstract Both parties in the active philosophical debate concerning the conceptual character of perception trace their roots back to Kant's account of sensible intuition in the Critique of Pure Reason. This striking fact can be attributed to Kant's tendency both to assert and to deny the involvement of our conceptual capacities in sensible intuition. He appears to waver between these two positions in different passages, and can thus seem thoroughly confused on this issue. But this is not, (...) in fact, the case, for, as I will argue, the appearance of contradiction in his account stems from the failure of some commentators to pay sufficient attention to Kant's developmental approach to philosophy. Although he begins by asserting the independence of intuition, Kant proceeds from this nonconceptualist starting point to reveal a deeper connection between intuitions and concepts. On this reading, Kant's seemingly conflicting claims are actually the result of a careful and deliberate strategy for gradually convincing his readers of the conceptual nature of perception.

ABSTRACT This paper explores some key features of Medieval accounts of intuition, focusing on Thomas Aquinas (1224/5–1274), on the one hand, and on Duns Scotus (c. 1266-1308), Peter Auriol (c. 1280–1322), and William Ockham (c. 1287-1347), on the other hand. The first section is devoted to the type of intuitive cognition which is accepted by all these authors, namely, the immediate and direct grasp of some present material object by the senses. It is from this basic sensory (...) class='Hi'>intuition – they agree – that human cognition starts. The second section turns to intuitive intellectual cognition and to the much greater disagreements which divide these philosophers. Notwithstanding these important differences, the paper’s conclusion draws attention to the similarities in the conception of intuition which cut across the otherwise significantly different accounts of the authors discussed. I end with an invitation to recover their older way of thinking of intuition. (shrink)

Abstract: This essay addresses three specific moments in the history of the role played by intuition in Kant's system. Part one develops Kant's attitude toward intuition in order to understand how ‘sensible intuition’ becomes the first step in his development of transcendental idealism and how this in turn requires him to reject the possibility of an ‘intellectual intuition’ for human cognition. Part two considers the role of Jacobi when it came to interpreting both Kant's epistemic (...) achievement and what were taken to be the outstanding problems of freedom's relation to nature; problems interpreted to be resolvable only via an appeal to ‘intellectual intuition’. Part three begins with Kant's subsequent return to the question of freedom and nature in his Critique of Judgment. With Goethe's contemporaneous Metamorphoses of Plants as a contrast case, it becomes clear that whereas Goethe can embrace the role of an intuitive understanding in his account of nature and within the logic of polarity in particular, Kant could never allow an intuition of nature that in his system would spell the very impossibility of freedom itself.

The debate between compatibilists and incompatibilists depends in large part on what ordinary people mean by ‘free will’, a matter on which previous experimental philosophy studies have yielded conflicting results. In Nahmias, Morris, Nadelhoffer, and Turner (2005, 2006), most participants judged that agents in deterministic scenarios could have free will and be morally responsible. Nichols and Knobe (2007), though, suggest that these apparent compatibilist responses are performance errors produced by using concrete scenarios, and that their abstract scenarios reveal the (...) folk theory of free will for what it actually is—incompatibilist. Here, we argue that the results of two new studies suggest just the opposite. Most participants only give apparent incompatibilist judgments when they mistakenly interpret determinism to imply that agents’ mental states are bypassed in the causal chains that lead to their behavior. Determinism does not entail bypassing, so these responses do not reflect genuine incompatibilist intuitions. When participants understand what determinism does mean, the vast majority take it to be compatible with free will. Further results indicate that most people’s concepts of choice and the ability to do otherwise do not commit them to incompatibilism, either, putting pressure on incompatibilist arguments that rely on transfer principles, such as the Consequence Argument. We discuss the implications of these findings for philosophical debates about free will, and suggest that incompatibilism appears to be either false, or else a thesis about something other than what most people mean by ‘free will’.

This paper looks at the history of the problem of individuation from Plato to Whitehead. Part I takes as its point of departure Reiner Wiehl’s interpretation of the different meanings of “abstract” in the metaphysics of Alfred North Whitehead and arrives at a corresponding taxonomy of different ways things can be called concrete. Part II compares the way philosophers in different periods understand the relation between thought and intuition. The view mostly associated with ancient philosophy is that thought (...) and sense-perception target different kinds of objects. The view mostly associated with modern philosophy (although it was introduced by the Stoics) is that thought and sense-perception are different ways of targeting the same objects. These differences have specific consequences for theories of individuation, which are assessed historically in Part III and then applied to Whitehead’s difficult texts in part IV. (shrink)

According to conciliatory views on the significance of disagreement, it’s rational for you to become less confident in your take on an issue in case your epistemic peer’s take on it is different. These views are intuitively appealing, but they also face a powerful objection: in scenarios that involve disagreements over their own correctness, conciliatory views appear to self-defeat and, thereby, issue inconsistent recommendations. This paper provides a response to this objection. Drawing on the work from defeasible logics paradigm and (...) abstract argumentation, it develops a formal model of conciliatory reasoning and explores its behavior in the troubling scenarios. The model suggests that the recommendations that conciliatory views issue in such scenarios are perfectly reasonable—even if outwardly they may look odd. (shrink)

Awareness is a two-place determinable relation some determinates of which are seeing, hearing, etc. Abstract objects are items such as universals and functions, which contrast with concrete objects such as solids and liquids. It is uncontroversial that we are sometimes aware of concrete objects. In this paper I explore the more controversial topic of awareness of abstract objects. I distinguish two questions. First, the Existence Question: are there any experiences that make their subjects aware of abstract objects? (...) Second, the Grounding Question: if an experience makes its subject aware of an abstract object, in virtue of what does it do so? I defend the view that intuitions, specifically mathematical intuitions, sometimes make their subjects aware of abstract objects. In defending this view, I develop an account of the ground of intuitive awareness. (shrink)

ABSTRACT In what sense is commitment essential to joint action, and do the participants in a joint action themselves perceive commitment as essential? Attempts to answer this question have so far been hampered by clashes of intuition. Perhaps this is because the intuitions in question have mostly been investigated using informal methods only. To explore this possibility, we adopted a more formal approach to testing intuitions about joint action, sampling naïve participants’ intuitions about experimentally controlled scenarios. This approach (...) did reveal patterns in participants’ responses which may hint at potential conceptual links between commitment and joint action. It did not however provide evidence to support the view that commitment is essential to joint action, at least not from the agents’ own perspective. We conclude that intuitions alone, even when drawn systematically from a large sample, may be a poor basis for theorizing about joint action. (shrink)

Adorno’s intensive criticism of phenomenology is well known, his entire early period during the 1920s and 1930s being marked by various polemical engagements with Husserl. This engagement finds its peak during his work at his second dissertation project in Oxford, a dissertation that was supposed to systematicaly expose the antinomies of phenomenological thinking while particularly focusing on Husserl’s concept of “eidetic intuition” or “intuition of essences”. The present paper will take this criticism as its starting point in focusing (...) on two highly specific aspects of Adorno’s interpretation: the opposition between eidetic intuition and the traditional theories of abstraction and its relationship to genetic phenomenology. In light of this criticism I subsequently show: 1. that, in his later work, Adorno’s understanding of eidetic intuition undergoes a significant revaluation; 2. that he reappropriates key elements of the eidetic method in his own procedure of physiognomic analysis, and 3. that his account of physiognomics is relevant for addressing the aforementioned incongruities of phenomenological eidetics itself.
