Nature is a part of our humanity, and without some awareness and experience of that divine mystery man ceases to be man.

We of the age of the machines, having delivered ourselves of nocturnal enemies, now have a dislike of night itself. With lights and ever more lights, we drive the holiness and beauty of night back to the forests and the sea.

The creatures with whom we share the planet and whom, in our arrogance, we wrongly patronize for being lesser forms, they are not brethren, they are not underlings, they are other nations, caught with ourselves in the net of life and time, fellow prisoners of the splendour and travail of the Earth.

The adventure of the sun is the great natural drama by which we live, and not to have joy in it and awe of it, not to share in it, is to close a dull door on nature's sustaining and poetic spirit.

The adventure of the sun is the greatest natural drama by which we live.

Into every empty corner, into all forgotten things and nooks, nature struggles to pour life, pouring life into the dead, life into life itself.

Animals are not brethren, they are not underlings; they are other nations, caught with ourselves in the net of life and time.
