Alfred Adler ranks with Freud and Jung among the great pioneers of modern psychiatry. In this book Dr. Adler presents a fascinating introduction to the principles of individual Psychology and demonstrates the practical application of these principles to everyday relationships. Dr. Adler points out that while mistakes in business or science are costly and deplorable, mistakes in the conduct of life are usually dangerous to life itself. The science of human nature cannot be pursued with the sole purpose of developing occasional experts, Dr. Adler says. Its proper goal is the understanding of human behavior by every human being, inasmuch as the power of self-knowledge and self-criticism lies within the scope of any intelligent adult.
