It's well-known that Kant believed that intuition was central to an account of mathematical knowledge. What that role is and how Kant argues for it are, however, still open to debate. There are, broadly speaking, two tendencies in interpreting Kant's account of intuition in mathematics, each emphasizing different aspects of Kant's general doctrine of intuition. On one view, most recently put forward by Michael Friedman, this central role for intuition is a direct result of the limitations of the syllogistic logic (...) available to Kant. On this view, Kant's reasons for introducing intuition are taken to be logical or mathematical, rather than philosophical. The other tendency, which I shall try to develop here, emphasizes an epistemological or phenomenological role for intuition in mathematics arising out of what may loosely be called Kant's ‘antiformalism.’This paper, which focuses specifically on the case of geometry, falls into two parts. First, I consider Kant's discussion of intuition in the Metaphysical Exposition of the concept of space. (shrink)

In early major works, Cassirer and Schlick differently recast traditional doctrines of the concept and of the relation of concept to intuitive content along the lines of recent epistemological discussions within the exact sciences. In this, they attempted to refashion epistemology by incorporating as its basic principle the notion of functional coordination, the theoretical sciences' own methodological tool for dispensing with the imprecise and unreliable guide of intuitive evidence. Examining their respective reconstructions of the theory of knowledge provides an axis (...) of comparison along which to locate Cassirer's Neo-Kantianism and Schlick's pre-positivist empiricism, and an immediate background of contrast to the subsequent rise of logical empiricism. For in the absence of intuition all our knowledge is without objects and therefore remains entirely empty. (Kant A62/B87) And how awkward is the human mind in diving the nature of things when forsaken by the analogy of what we see and touch directly? (Boltzmann 1895). (shrink)

This paper reconstructs the origins of Gettier-style epistemology, highlighting the philosophical and methodological debates that led to its development in the 1960s. Though present-day epistemologists assume that the search for necessary and sufficient conditions for knowledge began with Gettier’s 1963 argument against the JTB-definition, I show that this research program can be traced back to British discussions about knowledge and analysis in the 1940s and 1950s. I discuss work of, among others, Bertrand Russell, G. E. Moore, A. J. Ayer, Norman (...) Malcom, and A. D. Woozley, showing how exchanges between different schools of analytic philosophy gave rise to new ideas about the nature of knowledge and analysis. Finally, I turn to Gettier's intellectual development and argue that his paper was influenced by some of these debates, suggesting that even his interpretation of Plato’s definition of knowledge can be traced back to discussions in this period.

Fichte assigns ‘intellectual intuition’ a new meaning after Kant. But in 1799, his doctrine of intellectual intuition is publicly deemed indefensible by Kant and nihilistic by Jacobi. I propose to defend Fichte’s doctrine against these charges, leaving aside whether it captures what he calls the ‘spirit’ of transcendental idealism. I do so by articulating three problems that motivate Fichte’s redirection of intellectual intuition from being to acting: (1) the regress problem, which states that reflecting on empirical facts of consciousness leads (...) only to further facts and so cannot yield a first principle; (2) the rhapsody problem, which states that the categories form a haphazard set and so lack necessity unless they derive from a first principle; and (3) the nihilism problem, which states that a first principle cannot lie outside our cognition of it, lest it be the cause of our cognition and, being first, the cause of all our actions, reducing us to machines. Crucially, Fichte’s three motivating problems are in fact aspects of a single problem. Leaving any aspect unsolved spoils putative solutions to the other two. Consequently, Fichte requires a single unified solution to all three, which his doctrine of intellectual intuition provides. (shrink)

Textor reveals the roots of analytic philosophy in a great age of Austro-German philosophy in the late 19th and early 20th centuries. He introduces Brentano, Mach, and other key figures, and traces the development of the landmark ideas that there can be 'psychology without a soul', and that metaphysics lies beyond the limits of knowledge.

In his earliest philosophical work, Moritz Schlick developed a proposal for rendering aesthetics into a field of empirical science. His 1908 book Lebensweisheit developed an evolutionary account of the emergence of both scientific knowledge and aesthetic feelings from play. This constitutes the framework of Schlick’s evolutionary psychological methodology for examining the origins of the aesthetic feeling of the beautiful he proposed in 1909. He defends his methodology by objecting to both experimental psychological and Darwinian reductionist accounts of aesthetics. Having countered (...) these approaches, Schlick applies Külpe’s psychological distinction between stimulus-feelings and idea-feelings to collapse the traditional philosophical opposition between the agreeable and the beautiful. Both types of feeling, Schlick argues, result from humans’ adaptation to their environment. Because of this adaptation, feelings that were once only stimuli for action can come to be enjoyed for their own sake. This thesis underlies Schlick’s 1908 argument that art, qua mimesis, is necessarily inferior to aesthetic feelings directed towards the environment. Part of Schlick’s justification for this view is that humans are, through a long evolutionary process, better adapted to their environment than to artworks. Schlick nevertheless concedes that mimetic art can involve ways of abstracting from the objects it copies to produce idealised regularities that are not found in the original. Schlick thus concludes that art teaches its audience how to perceive the world in this abstract and idealised manner. This type of environmental aesthetics constitutes a means for reaching Schlick’s utopian ecological vision of a future in which culture will become harmonised with nature. (shrink)

It is well known that Husserl considered phenomenology to be First Philosophy—the ultimate science. For Husserl, this means that phenomenology must clarify the ultimate phenomenological-epistemological principle that leads to ultimate elucidation. But what is this ultimate principle and what does ultimate elucidation mean? It is the aim of this paper to answer these questions. In section 2, we shall discuss what role Husserl’s principle of all principles can play in the quest for ultimate elucidation and what it means for a (...) principle to be ultimately elucidating and ultimately elucidated. We will see that the Husserlian thesis that originary presentive intuitions are an immediate and the ultimate source of justification qualifies as the ultimate epistemological principle. (shrink)

Moritz Schlick’s work shaped Logical Empiricism and thereby an important part of philosophy in the first half of the 20th century. A continuous thread that runs through his work is a philosophical diagnosis of the ‘great errors in philosophy’: philosophers assume that there is intuitive knowledge/knowledge by acquaintance. Yet acquaintance, it is not knowledge, but an evaluative attitude. In this paper I will reconstruct Schlick’s arguments for this conclusion in the light of his early practical philosophy and his reading of (...) Schopenhauer’s The World as Will and Idea. Having the historical roots of Schlick’s position in view will put us in a position to explore and question its presuppositions. (shrink)

Wittgenstein’s use of the word ‘phenomenology’ to describe his own work in Philosophical Remarks and The Big Typescript has occasioned much puzzlement and confusion. This paper seeks to shed light on what Wittgenstein meant by the word through a close analysis of key passages in those two works. I argue against both the view of Nicholas Gier that Wittgenstein held ‘grammatical’ phenomenological remarks to be synthetic a priori and that expressed by Moritz Schlick that Wittgenstein held grammar to be tautological. (...) I also take issue with the claim by Merrill and Jaakko Hintikka that Tractatus Logico-Philosophicus ought to be regarded as a work of phenomenology. Wittgenstein’s adoption of a variant of Husserlian phenomenology, I argue, lasted no more than a few months, from February to October 1929, during which he conceived of phenomenology as something that sought to establish what one might call ‘analytic a posteriori’ truths through something like the Husserlian method of ‘bracketing’. By the end of 1929, I claim, he had abandoned that in favour of the view expressed in the slogan ‘phenomenology is grammar’, where ‘grammar’ is not confined to the tautological, but is rather intimately linked to Wittgenstein’s notion of ‘the understanding that consists in seeing connections’.

What are intuitions? Do they exist as distinctive mental states? Do they have an epistemic function? Can we discern specific features that characterize intuitions? Questions like these are widely d...

During the early modern period, a framework broadly attributable to Descartes sought to establish all knowledge on a foundation of indubitable truths that are fully clear and totally certain: intuitions. A powerful challenge to treating these seemingly unassailable intuitions as epistemic foundations is that the only truths which can be known in this fashion are so obvious and useless that they could not produce any other knowledge. Rationalists typically respond to this worry by maintaining that there are substantive intuitive truths. (...) Other natural options are to maintain that tautologous truths can serve as a fit foundation, or to reject this framework entirely. Empiricists like Locke, Hume, Condillac, and Mill opt for these other solutions. While Locke and Hume offer views that revise and refine this framework, Condillac and Mill engage in more radical departures from it. An interesting result of this difference in approach is that we see Locke and Hume subdividing reason between two domains – one in which intuition reigns, and one which is more properly the domain of the senses – while in Condillac and Mill we see two differing approaches – analysis and induction, respectively – to unifying all human reasoning within a single domain.

in kant’s account of cognition, Eric Watkins and Marcus Willaschek distinguish between a ‘broad’ and ‘narrow’ sense of Kant’s use of the term ‘cognition.’ Every “conscious representation that represents an object” counts as a cognition, taken in the broad sense.1 Every “conscious representation of a given object and of its general features” counts as a cognition in the narrow sense.2 In the case of finite beings, they argue, cognition in the narrow sense must fulfill two conditions: First, the object must (...) be given, since cognition must actually latch onto an object, and intuition satisfies that condition insofar as it immediately relates to the object represented in the intuition....

I advance a novel interpretation of Kant's argument that our original representation of space must be intuitive, according to which the intuitive status of spatial representation is secured by its infinitary structure. I defend a conception of intuitive representation as what must be given to the mind in order to be thought at all. Discursive representation, as modelled on the specific division of a highest genus into species, cannot account for infinite complexity. Because we represent space as infinitely complex, the (...) spatial manifold cannot be generated discursively and must therefore be given to the mind, i.e. represented in intuition. (shrink)

In this paper, I discuss Gaston Bachelard’s criticism of Henri Bergson’s employment of intuition as the specific method of philosophy, and as a reliable means of acquiring knowledge. I locate Bachelard’s criticism within the reception of Bergsonian intuition by rationalist philosophers who subscribed to the Third Republic’s ethos. I argue that the reasons of Bachelard’s rejection of Bergsonian intuition were not only epistemological, but also ethical and pedagogical. His view of knowledge as mediated, social, and historical, cannot be separated from (...) his conceptions of society, education, and the human being. (shrink)

The paper argues that Kant’s distinction between pure and empirical apperception cannot be interpreted as distinguishing two self-standing types of self-knowledge. For Kant, empirical and pure apperception need to co-operate to yield substantive self-knowledge. What makes Kant’s account interesting is his acknowledgment that there is a deep tension between the way I become conscious of myself as subject through pure apperception and the way I am given to myself as an object of inner sense. This tension remains problematic in the (...) realm of theoretical cognition but can be put to work and made productive in terms of practical self-knowledge. (shrink)

This paper advances the view that the history of philosophy is both a kind of history and a kind of philosophy. Through a discussion of some examples from epistemology, metaphysics, and the historiography of philosophy, it explores the benefit to philosophy of a deep and broad engagement with its history. It comes to the conclusion that doing history of philosophy is a way to think outside the box of the current philosophical orthodoxies. Somewhat paradoxically, far from imprisoning its students in (...) outdated and crystallized views, the history of philosophy trains the mind to think differently and alternatively about the fundamental problems of philosophy. It keeps us alert to the fact that latest is not always best, and that a genuinely new perspective often means embracing and developing an old insight. The upshot is that the study of the history of philosophy has an innovative and subversive potential, and that philosophy has a great deal to gain from a long, broad, and deep conversation with its history.

Monk’s ‘The Temptations of Phenomenology’ examines what the term ‘Phänomenologie’ meant for Wittgenstein. Contesting various other scholars, Monk claims that Wittgenstein’s relation to ‘Phänomenologie’ began and ended during 1929. Monk only partially touches on the question of Wittgenstein’s relation to the phenomenological movement during this time. Though Monk does not mention this, 1929 was also the year in which Ryle and Carnap turned their critical attention toward Heidegger. Wittgenstein also expressed his sympathy for Heidegger in 1929. Furthermore, though in 1929 (...) Wittgenstein agrees with the early Husserl on relating logic and science to phenomenology, it is not clear that they mean the same thing by either logic or phenomenology, or that they agree on what the relation between the two should be.

the ready availability of wittgenstein's previously unpublished writings from his so-called middle period of 1929 to 1936 has greatly enriched our understanding of the development of his thought. For obvious reasons, however, it has had little effect on the interpretation of Wittgenstein's contemporaries. At the time, few, even amongst those who had by then taken note of the Tractatus Logico-Philosophicus, were apprised of the new avenues Wittgenstein's thought had begun to take. One such rare exception was Moritz Schlick, the nominal (...) head of the Vienna Circle and an eminent philosopher of science. Even before Wittgenstein's return to... (shrink)

Philosophers have long tried to articulate the specific epistemic status of judgements that neither need nor admit of justification by drawing on the metaphor of ‘the light of truth’. In contrast, in Brentano's account of intuitive judgement correctness is central: intuitive or immediately evident judgements are ‘characterized as correct (right)’. The aim of my paper is to introduce and explore Brentano’s correctness-based view. I will conclude by relating it to the work of his students Meinong, Stumpf, and Husserl, who gradually (...) eroded Brentano’s insights. (shrink)

Over a period of several decades spanning the origin of the Vienna Circle, Schlick repeatedly attacked Husserl''s phenomenological method for its reliance on the ability to intuitively grasp or see essences. Aside from its significance for phenomenologists, the attack illuminates significant and little-explored tensions in the history of analytic philosophy as well. For after coming under the influence of Wittgenstein, Schlick proposed to replace Husserl''s account of the epistemology of propositions describing the overall structure of experience with his own account (...) based on the structure of language rather than on the intuition of essences. I discuss both philosophers'' accounts of the epistemology of propositions describing the structure of experience. For both philosophers, this epistemology was closely related to the general epistemology of logic; nevertheless, neither philosopher had a completely coherent account of it. Comparison of the two approaches shows that perennial and severe theoretical obstacles stand in the way of giving an epistemology of the structure of experience, a central requirement for both philosophers'' theories. Consideration of these obstacles sheds a new light on the reasons for the historically decisive split between the continental and the analytic traditions, as well as on the subsequent development of the analytic tradition away from the structural description of experience.

Henri Bergson and William James were great admirers of each other, and James seemed to think he got valuable ideas from Bergson. But early critics were right to see in Bergson the antithesis of pragmatism. Unfolding this antithesis is a convenient way to study important concepts and innovations in Bergson's philosophy. I concentrate on his ideas of duration and intuition, and show how they prove the necessity of going beyond pragmatism. The reason is because knowledge itself goes beyond the utilitarian (...) limitations in which pragmatism confines it. Knowledge is more than utility, more than adaptation, more than pragmatism, because our cognitive powers prove capable of more than any naturally selected service to survival. (shrink)

A complete reading of the works of Moritz Schlick reveals an apparent vacillation between a preference for holistic, formalistic accounts of knowledge and a preference for atomist, foundational accounts. A clearer picture of Schlick's philosophical development emerges from an appreciation of what I consider to be two separate "agendas," each of them fully formed and present in his earliest writings. Schlick's conviction that the assumptions in each agenda were equally correct can explain a good deal about the construction of his (...) mature theses and is, I believe, responsible for much of the criticism that his work has received, both before and after his death in 1936. Making the two agendas explicit can also provide us with a better framework within which to judge Schlick's work. Finally, the story provides an instructive example of how one's firmest beliefs constrain and dictate one's choice of solutions and perhaps define the problems themselves. (shrink)
