Aristotle: From Logic to Life

In our eighth and final lecture, we explore Aristotle’s powerful influence on 20th- and 21st-century philosophy, highlighting his “revenge” against logical positivism, which confined meaning to analytic and empirical claims. We examine how Elizabeth Anscombe, Philippa Foot, and Alasdair Mactyre revived virtue ethics by returning to human flourishing, character, and practical wisdom, and how Saul Kripke’s work on necessity and essence reopened metaphysics to Aristotelian ideas about substance and natural kinds. Dr. Orr closes by reflecting on Aristotle’s undeniable and enduring relevance as a living guide for contemporary philosophy.

In lecture seven, we witness Aristotle’s enduring impact on Western thought, tracing how his works were lost to Europe for centuries before their dramatic rediscovery through Arabic translations in medieval Spain and Byzantium—transforming universities and intellectual life. We explore the tensions between Aristotelian philosophy and Abrahamic monotheism, particularly over the eternity of the universe and the soul’s immortality, and how thinkers like Thomas Aquinas sought reconciliation. The lecture concludes by noting Aristotle’s decline during the Scientific Revolution and Enlightenment, followed by his significant revival in contemporary ethics and metaphysics.

In lecture six, we consider Aristotle’s Poetics, focusing on his theory of mimesis (artistic representation) and his defense of poetry—especially tragedy—against Plato’s claim that poets should be excluded from the ideal city. Aristotle argues that poetry does more than imitate appearances; it reveals universal patterns of human action, making it “more philosophical than history” because it shows what could happen according to probability and necessity. The lecture concludes with his definition of tragedy and the concept of catharsis, highlighting how tragic drama educates the emotions and contributes to moral and civic formation.

In lecture five, we investigate Aristotle’s Politics, focusing on his view that humans are “political animals” who achieve flourishing within a political community. He traces the natural development from household to village to the polis and argues that the city-state enables the good life. Dr. Orr also examines his sixfold classification of constitutions and his claim that a balanced polity—blending oligarchic and democratic elements and supported by public education—offers the most stable and practical form of government.
