About the book: 1986 / Does the world around us exist and is it what it seems to us? What are matter and motion? Is there purposefulness in nature? Is the emergence of consciousness an unsolvable mystery? These and many other questions are discussed in his book by the famous popularizer of science, writer Igor Adabashev. The book convincingly shows that a person is capable of cognizing the world around him, that the “world mysteries” that Christian theologians and idealist philosophers talk about are nothing more than not yet known, but completely knowable natural phenomena.
