The book “What is philosophy” by Gilles Deleuze and Felix Guattari is a deep and provocative study that poses many questions to the reader about the nature of philosophy and its role in the modern world. Written in 1991, this work continues to be relevant and of interest to those seeking to understand how philosophy can be applied to various aspects of life, art, and science. In What is Philosophy, Deleuze and Guattari offer their unique interpretation of the philosophical process, viewing it as a creative practice rather than just a set of abstract ideas. The authors argue that philosophy is not so much a system of knowledge as a way of thinking that allows us to create new concepts and ideas. They emphasize that philosophy should be dynamic and open, not static and dogmatic. This makes the book particularly attractive to those looking for fresh approaches to thinking and seeking to broaden their horizons. The book will be of interest to a wide range of readers: from students and teachers of philosophy to everyone who is interested in culture, art and science. If you like to think about how thoughts affect our perception of the world, or want to understand how philosophical ideas can be applied in practical life, this book will be a real find for you. It will also attract the attention of those who are fond of post-structuralism and deconstruction, as Deleuze and Guattari are key figures in these areas. The topics raised in What is Philosophy cover a wide range of issues, including the nature of knowledge, the role of art in philosophical discourse, and the ways in which philosophy can influence society. The authors explore how philosophy interacts with other disciplines and how it can help us cope with the challenges of modernity. In their approach, philosophy is seen as an active process that requires us not only to think, but also to act. This makes the book especially valuable for those who seek not only to understand philosophical concepts, but also to apply them in their lives. The style of Deleuze and Guattari is distinguished by brightness and imagery. They use a lot of metaphors and examples, which makes reading fascinating and accessible. Their dialogical approach allows the reader to feel like a participant in the discussion, and not just a passive listener. This creates an atmosphere of engagement and encourages reflection, which is one of the main values of the book. If you are interested in such works as Deleuze’s “You Are Not You” or Guattari’s “Anti-Oedipus”, then “What is philosophy” will be a logical continuation of your acquaintance with their work. This book will not only expand your knowledge of philosophy, but will also inspire new ideas and concepts that can change your perception of the world. In conclusion, "What is philosophy" is not just a book, but a real philosophical laboratory where the reader can experiment with thoughts and ideas. It opens new horizons and offers a fresh perspective on what it means to be a philosopher in the modern world. If you are ready for an intellectual adventure, this book is waiting for you.
