In Embodied Minds in Action, Robert Hanna and Michelle Maiese work out a unified treatment of three fundamental philosophical problems: the mind-body problem, the problem of mental causation, and the problem of action. This unified treatment rests on two basic claims. The first is that conscious, intentional minds like ours are essentially embodied. This entails that our minds are necessarily spread throughout our living, organismic bodies and belong to their complete neurobiological constitution. So minds like ours are necessarily alive. The second claim is that essentially embodied minds are self-organizing thermodynamic systems. This entails that our mental lives consist in the possibility and actuality of moving our own living organismic bodies through space and time, by means of our conscious desires. The upshot is that we are essentially minded animals who help to create the natural world through our own agency. This doctrine--the Essential Embodiment Theory--is a truly radical idea which subverts the traditionally opposed and seemingly exhaustive categories of Dualism and Materialism, and offers a new paradigm for contemporary mainstream research in the philosophy of mind and cognitive neuroscience

In this paper we (i) identify the notion of ‘essentially non-conceptual content’ by critically analyzing the recent and contemporary debate about non-conceptual content, (ii) work out the basics of broadly Kantian theory of essentially non-conceptual content in relation to a corresponding theory of conceptual content, and then (iii) demonstrate one effective application of the Kantian theory of essentially non-conceptual content by using this theory to provide a ‘minimalist’ solution to the problem of perceptual self-knowledge which is raised by Strong Externalism.

Episodic memory is usually regarded in a Conceptualist light, in the sense of its being dependent upon the grasp of concepts directly relevant to the act of episodic recollection itself, such as a concept of past times and of the self as an experiencer. Given this view, its development is typically timed as being in the early school-age years. We present a minimalist, Non-Conceptualist approach in opposition to this view, but one that also exists in clear contrast to the kind of minimalism espoused by Clayton and Dickinson with regard to memory in food-caching birds. While emphasising the nonconceptual elements of episodic memory we also insist on the essentially phenomenological nature of the memory. We propose the third year of life as a plausible onset period. Our view is rooted in Kantian assumptions about the spatiotemporal content of experience and about the synthetic unity of experience—and thus of re-experience. We answer two objections to this position

It is traditionally held that our knowledge of necessity is a priori; but the familiar theories of a priori knowledge – platonism and conventionalism – have now been discredited, and replaced by either modal skepticism or a posteriori essentialism. The main thesis of this paper is that Kant's theory of a priori knowledge, when detached from his transcendental idealism, offers a genuine alternative to these unpalatable options. According to Kant's doctrine, all epistemic necessity is grounded directly or indirectly on our capacity for clear and distinct rational intuition. Insight, in turn, depends upon functions of the imagination for creating “mental models” of necessary truths. This doctrine is well exemplified by Kant's account of our knowledge of simple analytic truths

In Rationality and Logic, Robert Hanna argues that logic is intrinsically psychological and that human psychology is intrinsically logical. He claims that logic is cognitively constructed by rational animals and that rational animals are essentially logical animals. In order to do so, he defends the broadly Kantian thesis that all rational animals possess an innate cognitive "logic faculty." Hanna 's claims challenge the conventional philosophical wisdom that sees logic as a fully formal or "topic-neutral" science irreconcilably separate from the species- or individual-specific focus of empirical psychology.Logic and psychology went their separate ways after attacks by Frege and Husserl on logical psychologism--the explanatory reduction of logic to empirical psychology. Hanna argues, however, that--despite the fact that logical psychologism is false--there is an essential link between logic and psychology. Rational human animals constitute the basic class of cognizers or thinkers studied by cognitive psychology; given the connection between rationality and logic that Hanna claims, it follows that the nature of logic is significantly revealed to us by cognitive psychology. Hanna 's proposed "logical cognitivism" has two important consequences: the recognition by logically oriented philosophers that psychologists are their colleagues in the metadiscipline of cognitive science; and radical changes in cognitive science itself. Cognitive science, Hanna argues, is not at bottom a natural science; it is both an objective or truth-oriented science and a normative human science, as is logic itself.

This paper is about the nature of the relationship between (1) the doctrine of Non-Conceptualism about mental content, (2) Kant's Transcendental Idealism, and (3) the Transcendental Deduction of the Pure Concepts of the Understanding, or Categories, in the B (1787) edition of the Critique of Pure Reason, i.e., the B Deduction. Correspondingly, the main thesis of the paper is this: (1) and (2) yield serious problems for (3), yet, in exploring these two serious problems for the B Deduction, we also discover some deeply important and perhaps surprising philosophical facts about Kant's theory of cognition and his metaphysics.

According to Kant in the Prolegomena, the natural kind proposition (GYM) "Gold is a yellow metal" is analytically true, necessary, and a priori. Saul Kripke and Hilary Putnam have argued that on the contrary propositions such as (GYM) are neither analytic, nor necessary, nor a priori. The Kripke-Putnam view is based on the doctrine of "scientific essentialism" (SE). It is a direct consequence of SE that propositions such as (GE) "Gold is the element with atomic number number 79" are metaphysically necessary and a posteriori. Were Kant to travel by time-machine to the present and to consider (GE), however, he would regard it as metaphysically contingent; and even if he were able to admit it as necessary, it would be synthetic a priori, and not a posteriori. In these ways, the conflict between Kant and the scientific essentialists is a sharply-defined one: if the essentialists are right, then the Kantian theory of meaning, necessity, and a priori knowledge is wrong; but if Kant is right, then SE is wrong. As a prolegomenon to the development and defense of Kant's positive theory of natural kind propositions, this paper undertakes a Kantian critique of SE. Following the Introduction, the paper has three sections. The first section spells out the main theses and assumptions of SE. The second section, setting aside the semantic and logical components of SE, focuses on its epistemic and metaphysical components and offers four Kantian arguments against them. The final section offers Kantian "diagnoses" of the flaws in SE exposed by the four critical arguments

Alfred North Whitehead (1861–1947) quotably wrote in 1929 that “the safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato.”1 The same could be said, perhaps with even greater accuracy, of the twentieth-century Euro-American philosophical tradition and Immanuel Kant (1724–1804).2 In this sense the twentieth century was the post-Kantian century. Twentieth-century philosophy in Europe and the USA was dominated by two distinctive and (after 1945) officially opposed traditions: the analytic tradition and the phenomenological tradition. Very simply put, the analytic tradition was all about logic and analyticity,3 and the phenomenological tradition was all about consciousness and intentionality.4 (See also “The birth of analytic philosophy,” Chapter 1; “The development of analytic philosophy: Wittgenstein and after,” Chapter 2; “American philosophy in the twentieth century,” Chapter 5; and “Phenomenology,” Chapter 15.) Ironically enough however, despite their official Great Divide, both the analytic and the phenomenological traditions were essentially continuous and parallel critical developments from an earlier dominant neo-Kantian tradition. This, by the end of the nineteenth century had vigorously reasserted the claims of Kant’s transcendental idealism against Hegel’s absolute idealism and the other major systems of post-Kantian German Idealism, under the unifying slogan “Back to Kant!” So again ironically enough, both the analytic and phenomenological traditions were alike founded on, and natural outgrowths from, Kant’s Critical Philosophy. By the end of the twentieth century however, and this time sadly rather than ironically, both the analytic and phenomenological traditions had not only explicitly rejected their own Kantian foundations and roots but also had effectively undermined themselves philosophically, even if by no means institutionally..

In this paper I argue that the Sellarsian Myth of the Given does not apply to all forms of Non-Conceptualism; that Kant is in fact a non-conceptualist of the right-thinking kind and not a Conceptualist, as most Kant-interpreters think; and that an intelligible and defensible Kantian Non-Conceptualism can be developed which supports the thesis that true perceptual beliefs are non-inferentially justified and also normatively funded by direct, embodied, intentional interactions with the manifest world (a.k.a. the Grip of the Given).
