The earth incites the wonder and admiration of man even though he is imperfect and his understanding greatly limited.

Man is a creative retrospection of nature upon itself.

The diversity of the phenomena of nature is so great, and the treasures hidden in the heavens so rich, precisely in order that the human mind shall never be lacking in fresh nourishment.

Man does find in Nature deliverance from himself, oblivion of his past, with peace and purity!

The world's a scene of changes, and to be constant, in nature were inconstancy.

Man seeks to change the foods available in nature to suit his tastes, thereby putting an end to the very essence of life contained in them.

For much of history it was possible to believe that the great diversity of life on Earth was a fixed creation, that the living world had never changed. But when the first stirrings of industry demanded that fuel be dug from the earth and hillsides be leveled for roads and railways, the Earth's true past was dug up in abundance.

Knowledge of the past and of the places of the earth is the ornament and food of the mind of man.

Those who seek to satisfy the mind of man by hampering it with ceremonies and music and affecting charity and devotion have lost their original nature.

All historical experience demonstrates the following: Our earth cannot be changed unless in the not too distant future an alteration in the consciousness of individuals is achieved.
