“The range of human potentialities is also the range of human needs because of man's vital drive that impels him to seek to realize his potentialities. this drive is even more mysterious than the potentialities it seeks to realize.”

Ch 13 "The Forfeited Self".
The Feminine Mystique (1963)

Transhumanism (1957)
Context: We are beginning to realize that even the most fortunate people are living far below capacity, and that most human beings develop not more than a small fraction of their potential mental and spiritual efficiency. The human race, in fact, is surrounded by a large area of unrealized possibilities, a challenge to the spirit of exploration.

The New Divinity (1964)
Context: Human potentialities constitute the world's greatest resource, but at the moment only a tiny fraction of them is being realized. The possibility of tapping and directing these vast resources of human possibility provide the religion of the future with a powerful long-term motive. An equally powerful short-term motive is to ensure the fullest possible development and flowering of individual personalities. In developing a full, deep and rich personality the individual ceases to be a mere cog or cipher, and makes his own particular contribution to evolutionary fulfilment.
