The Phileb, Cratil, Theaetetus, and Sophist dialogues raise themes such as happiness, truth, the essence of things, and the nature of knowledge. Each of these dialogues is an intellectual game in which Plato uses the method of Socratic dialogue to encourage his interlocutors to reflect and seek answers. The reader witnesses intense discussions in which philosophers explore what it means to be wise, what are the limits of human knowledge, and how we can distinguish truth from error. This book will be of interest to a wide range of readers: from undergraduate and graduate students studying philosophy to lovers of deep reflections on life and its meaning. If you are interested in questions related to ethics, metaphysics or epistemology, then the “Plato’s Works” will become a real treasure for you. It is also suitable for those who seek inspiration for personal reflection or wish to expand their horizons in the field of philosophy. One of the features of this publication is the translation and comments of Professor Karpov, which makes the text more accessible to the modern reader. His explanations help to better understand the context and ideas embedded in Plato's dialogues. Karpov not only translates, but also interprets, which avoids possible misunderstandings and facilitates the perception of complex philosophical concepts. This makes the book a valuable resource for both scholars and philosophy lovers. The topics raised in these dialogues remain relevant in our time. In Philebe, Plato explores what true happiness is and how it relates to virtue and knowledge. Cratil offers an in-depth discussion on language and its role in shaping our understanding of the world. Theaetetus questions the nature of knowledge and its sources, and Sophist delves into questions about the essence and difference between philosophy and sophistry. These ideas not only enrich the philosophical discourse, but also encourage the reader to think about their own beliefs and understanding of the world. Plato's style, with its vivid metaphors and dialogue form, creates a lively atmosphere in which thoughts and ideas develop in the dynamics of discussion. By reading it, you are not just immersed in the text, but also become a participant in a philosophical dialogue that can change your perception of reality.
