Sebastian Angus Gardner (born 19 March 1960) is a British philosopher and Professor of Philosophy in the University College London.
He is known for his expertise on Kant, German Idealism, Sartre and Freud, and for his philosophical interpretations and investigations in the subject of psychoanalytic theory.
[3] He has written extensively on Freud and psychoanalysis, on Kant, and on post-Kantian philosophy, including Fichte, Schelling, Hegel and Nietzsche.
Gardner argues for the failure of sub-systemic theories of the mind (such as those of cognitive psychology) to provide a framework for actively irreconcilable or self-contradicting actions, utterances, or impulses, which can be conceptualised as internal to the subject.
[4] Gardner has written multiple essays on authors including Freud, Nietzsche, Derrida, Habermas, Lacan, and has more recently published books on Kant's Critique of Pure Reason and Sartre's Being and Nothingness.
