The book of one of the classics of Russian psychology P.Ya. Galperin discusses issues that are significant not only for psychologists and philosophers, but sooner or later arise before every thinking intellectual person. The book is called "Introduction to Psychology" not only because the same name has one of the most important works of Pyotr Yakovlevich Halperin, which became a bibliographic rarity immediately after its publication more than 20 years ago and has never been reprinted since, but has not lost its freshness and sharpness. Psychology students will receive a great tutorial on the introductory part of the course, making you think, argue, and keeping you awake.
