Science is the only truth and it is the great lie. It knows nothing, and people think it knows everything. It is misrepresented. People think that science is electricity, automobilism, and dirigible balloons. It is something very different. It is life devouring itself. It is the sensibility transformed into intelligence. It is the need to know stifling the need to live. It is the genius of knowledge vivisecting the vital genius.

Autumn is as joyful and sweet as an untimely end.

Art includes everything that stimulates the desire to live

The woman who loves always smells good.

To know what everyone knows is to know nothing.

Art includes everything which stimulates the desire to live; science includes everything which sharpens the desire to know. Art, even the most disinterested, the most disembodied, is the auxiliary of life.

Very simple ideas lie within the reach only of complex minds.
