In science, the best precept is to alter and exchange our ideas as fast as science moves ahead.

Claude Bernard

Those who have an excessive faith in their theories or in their ideas are not only poorly disposed to make discoveries, but they also make very poor observations.

Priestley said that each discovery we make shows us many others that should be made.

Those who do not know the torment of the unknown cannot have the joy of discovery.

It is what we know already that often prevents us from learning.

A great discovery is a fact whose appearance in science gives rise to shining ideas, whose light dispels many obscurities and shows us new paths.
