Can a person be truly free if everything in the world is subject to causes? This is what PhD candidate Nikolai Biryukov invites us to ponder. The question of free will and determinism has remained relevant for millennia. It is one of those topics that shape our worldview and attitude towards life. The lecture, prepared by PhD candidate Nikolai Biryukov, is structured as a dialogue: theoretical analysis alternates with open discussion, allowing each participant to express their doubts, ideas, and arguments. The starting point of the lecture will be the ancient Greek schools - the Stoics and Epicureans - who laid the foundations for opposing approaches to the concept of freedom. Then, it will explore how Spinoza attempted to reconcile causality with inner freedom, and how the Marxist tradition framed will within the bounds of social necessity. Finally, the lecturer will illuminate the latest approaches - from neuroscience to analytical philosophy - to see how this age-old contradiction is interpreted today. The event is primarily aimed at students and graduates of philosophy and humanities programs, as well as anyone who is concerned with questions of meaning, responsibility, and personal choice. The lecture will suit those seeking intellectual challenges, who enjoy debate and reflection, and are not afraid to change their viewpoint under the influence of compelling arguments.
