The objective of the article is to broach the problem of body mind duality through the discussion of the concept of normativity of life, proposed by Canguilhem. Highlights the necessity to overcome the historic controversy between mechanism and vitalism, and to construct a concept that incorporates the psychic dimension as an extension of organic in human. Seek to make a link between open questions in biology and in physics and presents Roger Penrose's ideas about connection between physics and mind. Questions the possibility of 20 TH century physics has to be inscribed in 21 TH century biology. To deal with this challenge it is necessary to consider human limits to know the universe. Based on this discussion, reaffirms that human psychic dimension could be evolved from an anterior biological capacity to perform "choices" to make life to persevere.
