If I had to define life in a single phrase, I should clearly express my thought of throwing into relief one characteristic which, in my opinion, sharply differentiates biological science. I should say: life is creation.
CLAUDE BERNARD -
The doubter is a true man of science: he doubts only himself and his interpretations, but he believes in science.
