The version of Kantian ethics that Robert Hanna develops in Kantian Ethics and Human Existence is “existential” in four senses of that term. First, it’s a specifically anthropocentric, humane version of Kantian ethics, that takes philosophical anthropology fully seriously for the purposes of ethical theory, and not as an inessential add-on or mere elaboration. Second, … [continue reading]

What is free will? What is practical agency? What is human personhood? And how are human free will, practical agency, and human personhood really possible in the natural world as it is correctly characterized by the modern natural sciences, especially physics, chemistry, biology, and cognitive neuroscience? Or more compactly put: given the truth of modern … [continue reading]

In Cognition, Content, and the A Priori, Robert Hanna works out and defend a five-stage contemporary Kantian theory of (i) intentionality and its contents, including nonconceptual content and conceptual content, (ii) sense perception and perceptual knowledge, including perceptual self-knowledge, (iii) the analytic-synthetic distinction,(iv) the nature of logic, and (v) a priori truth and knowledge in … [continue reading]

Most contemporary philosophers (71.1%, according to a recent survey) believe that a priori knowledge is really possible. Indeed, since the late 1980s there has been a renewed and steadily growing interest in rationalism and the a priori; and gradually what George Bealer has dubbed a rationalist renaissance has emerged onto the contemporary philosophical scene. At … [continue reading]

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 … [continue reading]

The main aim of Robert Hanna’s Kant, Science, and Human Nature is to show that Kant was essentially right about the unknowability and methodological eliminability of a microphysical noumenal world hiding behind the directly perceivable manifestly real macrophysical world, and also about the priority of practical reason over theoretical reason, and that the mainstream analytic … [continue reading]

In Kant and the Foundations of Analytic Philosophy, 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 relation between them. The rise of Analytic philosophy decisively marked the end of the hundred-year dominance of Kant’s philosophy … [continue reading]

Robert Hanna’s The Fate of Analysis (Mad Duck Coalition, 2021) is a comprehensive revisionist study of the history of Analytic philosophy from the early 1880s to the present, with special attention paid to Ludwig Wittgenstein’s work and the parallels and overlaps between the Analytic and Phenomenological traditions. It provides a synoptic introduction to European and … [continue reading]

Robert Hanna’s Rationality and Logic (MIT Press, 2006) is about human rationality, logic, and the connection between them. According to Hanna’s view, this connection is both constitutive and mutual. More precisely, he defends the broadly Kantian thesis that logic is the result of the constructive operations of an innate protological cognitive capacity that is necessarily … [continue reading]
