“When you look more generally at life on Earth, you find that it is all the same kind of life.”
The Varieties of Scientific Experience: A Personal View of the Search for God (2006)
Context: When you look more generally at life on Earth, you find that it is all the same kind of life.... It uses about fifty fundamental biological building blocks, organic molecules.... with trivial exceptions, all organisms on Earth use... an enzyme, to control the rate and direction of the chemistry of life.... a nucleic acid to encode the hereditary information... the identical code book for translating nucleic acid language into protein language.... At the molecular level, we are all virtually identical.

Variant: You will find, as you look back upon your life, that the moments when you really lived are the moments when you have done things in the spirit of love.

Quoted in A Living Architecture : Frank Lloyd Wright and Taliesin Architects (2000) by John Rattenbury
Context: Human beings can be beautiful. If they are not beautiful it is entirely their own fault. It is what they do to themselves that makes them ugly. The longer I live the more beautiful life becomes. If you foolishly ignore beauty, you will soon find yourself without it. Your life will be impoverished. But if you invest in beauty, it will remain with you all the days of your life.
