The history of science is science itself; the history of the individual, the individual.

The work of art may have a moral effect, but to demand moral purpose from the artist is to make him ruin his work.

Our passions are true phoenixes; as the old burn out the new straight rise up from the ashes.

Not art and science only, but patience will be required for the work.

Out of moderation a pure happiness springs.
