This text offers a critical re-evaluation of Aristotle's traditional division of philosophy into theoretical and practical branches. The author argues that while this distinction has endured for over two millennia, the meanings of both terms have evolved and must be redefined in the context of specific thinkers. The central thesis posits that purely theoretical philosophy, understood as a passive contemplation of truth, is impossible. Instead, all thinking is a form of activity and learned practice that requires the mastery of specific procedures and routines. Consequently, the distinction between theoretical and practical should not be based on the nature of the human activity itself, but rather on the object toward which that activity is directed. The text also reflects on the contemporary shift away from first philosophy toward second philosophies focused on social, political, or scientific issues. The author views this trend as a retreat from fundamental philosophical questions in favor of real-world problems that science cannot fully resolve. Ultimately, philosophy is presented as an inherently practical discipline of continuous intellectual improvement.
