The human mind is the infinite …

The human mind is the infinite possible. The master-works, immense worlds, are generated within it unceasingly; and abide there forever. No crowding of one against the other; no recoil. The occlusions, when there are any, are but apparent, and quickly cease. The expanse of the boundless admits all creations.

William Shakespeare by Victor Hugo

The human mind has a summit …

The human mind has a summit, – the ideal; to this summit God descends, man rises.

William Shakespeare by Victor Hugo
