The only way of full knowledge lies in the act of love; this act transcends thought, it transcends words. It is the daring plunge into the experience of union. To love somebody is not just a strong feeling – it is a decision, it is a judgement, it is a promise.
– Erich Fromm, The Art of Loving.
Erich Seligmann Fromm (March 23, 1900 – March 18, 1980) was a German social psychologist, psychoanalyst, sociologist, humanistic philosopher, and democratic socialist. He was associated with what became known as the Frankfurt School of critical theory.
