Early life and education
Quassim Cassam was born in Mombasa, Kenya, to a Gujarati Ismaili family. His parents and grandparents were all born in Kenya. His great grandparents were born in Gujarat, India, and emigrated to Kenya in the 1890s. He was a Kenyan citizen until the age of 18 but has spent most of his adult life in the U.K. He studied Philosophy, Politics and Economics (PPE) at Keble College, Oxford and was awarded an Oxford doctorate in 1985 for a dissertation on transcendental arguments.

Career

In 2004 he held the John Evans Distinguished Visiting Professorship in Moral and Intellectual Philosophy at Northwestern University, Illinois. He was Professor of Philosophy at University College London in 2005-2006 and Knightbridge Professor of Philosophy at Cambridge University in 2007–2008.

Cassam's early publications were mostly on Kant, including "Transcendental Arguments, Transcendental Synthesis, and Transcendental Idealism" (Philosophical Quarterly, 1987) and "Kant and Reductionism" (Review of Metaphysics, 1989). In recent times he has published work on epistemic vices and introduced the label 'vice epistemology' for the philosophical study of the nature and significance of epistemic vices such as closed-mindedness, overconfidence, dogmatism and wishful thinking
