Morality is truth in full bloom.

A bird sings, a child prattles, but it is the same hymn; hymn indistinct, inarticulate, but full of profound meaning.

In winter there is no heat, no light, no noon, evening touches morning, there is fog, and mist, the window is frosted, and you cannot see clearly. The sky is but the mouth of a cave. The whole day is the cave.... Frightful season! Winter changes into stone the water of heaven and the heart of man.

In the vast cosmical changes, the universal life comes and goes in unknown quantities, ... sowing an animalcule here, crumbling a star there, oscillating and ... entangling, from the highest to the lowest, all activities in the obscurity of a dizzying mechanism, hanging the flight of an insect upon the movement of the earth... Enormous gearing, whose first motor is the gnat, and whose last wheel is the zodiac.
