Life always tends to unite and integrate; in other words, life by necessity is a process of constant growth and change. Indeed, when growth and change cease, there is death. Life does not grow wild and unstructured; every living being has its own form and structure implanted in its chromosomes. It can grow more fully, more perfectly, but it can not grow into what it was not born to become. ― (1967e: Do We Still Love Life?, in: McCalls, New York, Vol. 94 (August 1967)

Living itself is an art – in fact, the most important and at the same time the most difficult and complex art to be practiced by man. Its object is not this or that specialized performance, but the performance of living, the process of developing into that which one is potentially. In the art of living, man is both the artist and the object of his art; he is the sculptor and the marble; the physician and the patient. ― (1947a: Man for Himself. An Inquiry into the Psychology of Ethics, New York (Rinehart and Co.) 1947, pp. 17f.)
