This is the first collection of essays devoted to the thought of Anselm W. Muller. It brings to the attention of the English-speaking world an influential and highly regarded philosopher who has made important contributions to a wide range of philosophical debates. Arguably, Muller's most important contributions are to the philosophy of action and virtue ethics. The contributors, who include friends, colleagues, and former students, engage with different aspects of Muller's thought in these areas. Subjects include his interpretation of Aristotle and Wittgenstein, the teleology of thought and action, the Aristotelian distinction between poiesis and praxis and its application to ethical upbringing, and the possibility of practical knowledge and practical truth. Teleological Structures in Human Life will be of interest to researches and advanced students working on virtue ethics, philosophy of action, and practical reasoning.
