In "Understanding Human Nature", Adler explores human personality from all angles - how character develops, the nature of the psyche, how we see the world and how we become who we are. He investigates character traits of different types, exploring moods, feelings and emotions, from envy and greed to grief and joy. Through this study, we are introduced to the main themes of Alfred Adler's work, all of which have made a significant contribution to contemporary psychology, with many of them, such as "inferiority" and "superiority complex", entering everyday language without people knowing their source. Adler is one of the founding fathers of modern psychology, along with Freud and Jung. This translation makes his ideas accessible to a new generation of readers in a fresh, readable and attractive edition. It demonstrates the relevance for modern thinking of Adler's psychology and offers readers an invaluable comparison to the work of Freud and Jung.
