Man can learn nothing unless he proceeds from the known to the unknown.

Claude Bernard

Well-observed facts, though brought to light by passing theories, will never die; they are the material on which alone the house of science will at last be built.

Men who believe too firmly in their theories, do not believe enough in the theories of others. So these despisers of their fellows make experiments only to destroy a theory, instead of to seek the truth.
CLAUDE BERNARD

The joy of discovery is certainly the liveliest that the mind of man can ever feel.

When entering on new ground we must not be afraid to express even risky ideas so as to stimulate research in all directions. As Priestley put it, we must not remain inactive through false modesty based on fear of being mistaken.
CLAUDE BERNARD

Afraid Direction Fear Ground Ideas Mistake Modesty Risk
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.
