To Have or to Be? is one of the seminal books of the second half of the 20th century. Fromm's thesis is that two modes of existence struggle for the spirit of humankind: the having mode, which concentrates on material possessions, power, and aggression, and is the basis of the universal evils of greed, envy, and violence; and the being mode, which is based on love, the pleasure of sharing, and in productive activity.

The renowned social psychologist delves deep into the fraught relationship between genders, drawing upon the influential insights of Bachofen, Freud, Marx, and Briffault. Not primarily interested in the existence of anatomical and biological differences between the sexes, Fromm instead analyzes how these differences have been made use of throughout human history.

This classic work by psychologist and social philosopher Eric Fromm builds upon his previous popular book To Have or to Be? The Art of Being teaches us to avoid the tantalizing illusions of our consumer-driven world by learning to function as a whole person from a state of inner completeness or being. The transition from an identity of having to being creates a state of enlightened psychological and spiritual happiness.

As Erich Fromm points out, ours is "a life between having and being"—between mere having and healthy being, between destructiveness and creativity, between narcissism and productive self-understanding, between passivity and the joy of positive activity. The alternatives of having and being are basic orientations of our character and determine our behavior. The mostly unpublished and unknown texts featured in The Essential Fromm encapsulate the psychologist's views on the fulfilling life.

The Sane Society is a continuation and extension of the brilliant psychiatric concepts Erich Fromm first formulated in Escape from Freedom; it is also, in many ways, an answer to Freud’s Civilization and its Discontents. Fromm examines man’s escape into over conformity and the danger of robotism in contemporary industrial society: Modern humanity has, he maintains, been alienated from the world of their own creation. Here Fromm offers a complete and systematic exploration of his “humanistic psychoanalysis.”
