Q. $S_1$: Biological evolution has not fitted man to any specific environment.
P: It is by no means a biological evolution, but it is a cultural one.
Q: His imagination, his reason, his emotional subtlety and toughness, makes it possible for him not to accept the environment but to change.
R: And that series of inventions by which man from age by age has reshaped his environment is a different kind of evolution.
S: Among the multitude of animals which scamper, burrow swim around us he is in the only one who is not locked in to his environment.
