Spirit itself is not human; it may spring up in any life... it may exist in all animals, and who know in how many undreamt-of beings, or in the midst of what worlds?

The line between what is known scientifically and what has to be assumed in order to support knowledge is impossible to draw. Memory itself is an internal rumour.

Experience seems to most of us to lead to conclusions, but empiricism has sworn never to draw them.

Nothing is inherently and invincibly young except spirit. And spirit can enter a human being perhaps better in the quiet of old age and dwell there more undisturbed than in the turmoil of adventure.

Bid, then, the tender light of faith to shine By which alone the mortal heart is led Unto the thinking of the thought divine.

You and I possess manifold ideal bonds in the interests we share; but each of us has his poor body and his irremediable, incommunicable dreams.

The existence of any evil anywhere at any time absolutely ruins a total optimism.
