Science is the real moral school; she teaches man the love and respect for the truth, without which all hope is chimerical. - Marcellin Berthelot

Science... dominates all things, it alone is of any definite utility. No man, no institution shall henceforth have an enduring authority if they do not conform themselves to its precepts.

In fact, what we are can only be attributed for a small part to our labour and personal individuality, because we owe it almost entirely to our forefathers, both of blood and mind.

The most interesting of the services rendered by science is perhaps shown by comparing the servile and miserable condition of the popular masses in the past with their present state, already so much raised in dignity and comfort, without prejudice to the hopes which they are gradually realising.
