Abraham H. Maslow was one of the foremost spokespersons of humanistic psychology. In The Farthest Reaches of Human Nature, an extension of his classic Toward a Psychology of Being, Maslow explores the complexities of human nature by using both the empirical methods of science & the aesthetics of philosophical inquiry. With essays on biology, synergy, creativity, cognition, self-actualization & the hierarchy of needs, this posthumous work is a wide-ranging synthesis of his inspiring & influential ideas.
