The whole life lies in the verb seeing.

It is not our heads or our bodies which we must bring together, but our hearts. . . . Humanity. . . is building its composite brain beneath our eyes.

To write the true natural history of the world, we should need to be able to follow it from within. It would thus appear no longer as an interlocking succession of structural types replacing one another, but as an ascension of inner sap spreading out in a forest of consolidated instincts. Right at its base, the living world is constituted by conscious clothes in flesh and bone.

The dog knows, but does not know that he knows.

Isolation is a blind alley....Nothing on the planet grows except by convergence.
