We must remain, in a word, in an intellectual disposition which seems paradoxical, but which, in my opinion, represents the true mind of the investigator. We must have a robust faith and yet not believe.
CLAUDE BERNARD

Now, a living organism is nothing but a wonderful machine endowed with the most marvellous properties and set going by means of the most complex and delicate mechanism.

The better educated we are and the more acquired information we have, the better prepared shall we find our minds for making great and fruitful discoveries.

CLAUDE BERNARD
