This book is not a manual on psychology or even just a popular presentation of long and widely known truths. The author, a well-known psychologist, collected in it a large number of questions of interest to our youth, and in short stories, entertaining and accessible, gave answers to them from the standpoint of modern knowledge. Indeed, who today is not interested in: how to develop will, memory, become attentive; what is conscience, duty and love in terms of psychological science; whether the thought can be transmitted from a distance; what dreams are; does the dog and ant have consciousness and more?
