    A reply to contemporary skepticism about intuitions and a priori knowledge, and a defense of neo-rationalism from a contemporary Kantian standpoint, focusing on the theory of rational intuitions and on solving the two core problems of justifying and explaining them

    Kant’s Non-Conceptualism, Rogue Objects, and The Gap in the B Deduction
    International Journal of Philosophical Studies 19 (3). 2011.
    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 als…Read more

    Robert Hanna works out a unified contemporary Kantian theory of rational human cognition and knowledge. Along the way, he provides accounts of intentionality and its contents, sense perception and perceptual knowledge, the analytic-synthetic distinction, the nature of logic, and a priori truth and knowledge in mathematics, logic, and philosophy. This book is specifically intended to reach out to two very different audiences: contemporary analytic philosophers of mind and knowledge, and contempor…Read more

    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 distinctiv…Read more

    THERE IS A NOTORIOUS THESIS in the philosophy of language which runs as follows: meanings are wholly mind-dependent, in the sense that they exist only in particular human minds. We might call this "the thesis of semantic psychologism." Versions of this thesis have been attacked and rejected by some of the most important philosophers of language in the twentieth century: Frege, Husserl, Wittgenstein, and, most recently, Hilary Putnam.

    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 wo…Read more

    Kant, science, and human nature
    Oxford University Press. 2006.
    Robert Hanna argues for the importance of Kant's theories of the epistemological, metaphysical, and practical foundations of the "exact sciences"--relegated to the dustbin of the history of philosophy for most of the 20th century. In doing so he makes a valuable contribution to one of the most active and fruitful areas in contemporary scholarship on Kant.

    The Unity of Understanding (review)
    Review of Metaphysics 44 (4): 864-865. 1991.
    To think is to think-about objects; this simple fact is of course what philosophers of mind have dubbed "intentionality." The traditional doctrine of intentionality has it that the mind pictures or in some sense represents its objects to itself. Kant initiates a radical departure from this doctrine by insisting that the mind forms or in some sense constructs its objects. This power of mental construction Kant calls the "understanding".

    Kant and the foundations of analytic philosophy
    Oxford University Press. 2001.
    Robert Hanna presents a fresh view of the Kantian and analytic traditions that have dominated continental European and Anglo-American philosophy over the last two centuries, and of the connections between them. But this is not just a study in the history of philosophy, for out of this emerges Hanna's original approach to two much-contested theories that remain at the heart of contemporary philosophy. Hanna puts forward a new 'cognitive-semantic' interpretation of transcendental idealism, and a v…Read more

    Hegel's logic is often understood as a competitor to ordinary formal logic; this leads to such false accusations as that hegel "denies the principle of non-Contradiction." on the contrary, Hegel's speculative logic is wholly conservative with respect to ordinary logic. What hegel denies is ordinary logic's suitability to be a paradigm for philosophy. Hegel's logic, Itself, Can be seen as arising from a critical ontological reflection on ordinary logic

    In Skeptical idealism says that possibly nothing exists outside my own conscious mental states. Purported refutations of skeptical idealism – whether Descartes's, Locke's, Reid's, Kant's, Moore's, Putnam's, or Burge's – are philosophically scandalous: they have convinced no one. I argue (1) that what is wrong with the failed refutations is that they have attempted to prove the wrong thing – i.e., that necessarily I have veridical perceptions of distal material objects in space, and (2) that a ch…Read more

    Perspective in Whitehead's Metaphysics (review)
    Review of Metaphysics 37 (3): 650-652. 1984.
    Recent books on Whitehead have shown a marked tendency to use Whiteheadian notions in ways not strictly compatible with Whitehead's own explicit views. This fact may suggest either the fecundity of Whitehead's ideas, or a general dissatisfaction with the fully developed cosmological scheme as outlined in Process and Reality. In any case, Ross's book continues in the recent tradition of "neo-Whiteheadian" as opposed to "strictly Whiteheadian" interpretations of Whitehead's thought. The purpose of…Read more

    It is nowadays a commonplace of Kant-interpretation that Kant's response to Hume in the Analogies of Experience is not strictly speaking a refutation of Hume but in fact only an extended critical response to Hume's skeptical accounts of object-identity and causation, that also accepts many of Hume's working assumptions. But this approach can significantly underestimate the extent to which Kant's conception of the representational mind is radically distinct from Hume's. In particular, Kant's conc…Read more

    This essay is about how four deeply important Kantian ideas can significantly illuminate some essentially intertwined issues in philosophical theology, philosophical logic, the metaphysics of agency, and above all, morality. These deeply important Kantian ideas are: (1) Kant’s argument for the impossibility of the Ontological Argument, (2) Kant’s first “postulate of pure practical reason,” immortality, (3) Kant’s third postulate of pure practical reason, the existence of God, and finally (4) Kan…Read more
  • Simple or "standard" empirical judgments--as expressed in such statements as "The rose is red" or "Socrates is mortal"--are logically basic for theoretical rationality. All the more complex forms of judgment presuppose the existence and tenability of judgments of the "standard" type. The overall aim of this study is twofold: to show how the traditional theory of standard empirical judgments--as represented by Kant's doctrine of judgment--is subject to a through-going form of skepticism that I en…Read more

    Embodied minds in action
    Oxford University Press. 2009.
    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 constitutio…Read more

    A Kantian critique of scientific essentialism
    Philosophy and Phenomenological Research 58 (3): 497-528. 1998.
    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 metaphysical…Read more

    Mathematics for humans: Kant's philosophy of arithmetic revisited
    European Journal of Philosophy 10 (3). 2002.
    In this essay I revisit Kant's much-criticized views on arithmetic. In so doing I make a case for the claim that his theory of arithmetic is not in fact subject to the most familiar and forceful objection against it, namely that his doctrine of the dependence of arithmetic on time is plainly false, or even worse, simply unintelligible; on the contrary, Kant's doctrine about time and arithmetic is highly original, fully intelligible, and with qualifications due to the inherent limitations of his …Read more
