|A "secret of life" discussion by Alan Watts, wherein he hinges the topic around the nature of "spontaneity"; which, at some points, to note, seems to similar to Robert Pirsig's 1991 discussions on the perceptual confusion surrounding the terms: struggle and survive in a chemical sense.|
Crick, to note, in 1966, said "we should abandon the word alive" (see: defunct theory of life), in that some thing "alive" is does not exist (see: life does not exist) as chemistry and physics sees things.
The phrase “secret of life”, supposedly, is attributed Francis Crick who on 18 Apr 1953 is said to have stepped into the Eagle Pub in Cambridge England and declared in triumph to have “discovered the secret of life” together with James Watson. 
The following are related quotes:
“The results of particle physics are in no sense more fundamental then what Alan Turing did in founding the computer science, or what Francis Crick and James Watson did in discovering the secret of life.”— Philip Anderson (1986), commentary on proposal to build a Super Collider 
“The DNA revolution led a generation of biologists to believe that the secret of life lay entirely in the structure and function of DNA. This faith is misplaced and the reductionist programme must be supplemented with a new conceptual framework.”— Harry Rubin (1988), “Molecular Biology Running into a Cul-de-sac?”
