The fertility cycle is a cycle entirely of living creatures passing again and again through birth, growth, maturity, death, and decay.

We are working well when we use ourselves as the fellow creatures of the plants, animals, materials, and other people we are working with. Such work is unifying, healing. It brings us home from pride and from despair, and places us responsible within the human estate. It defines us as we are: not too good to work with our bodies, but too good to work poorly or joylessly or selfishly or alone. (pg. 134, The Body and the Earth)

As the births of living creatures are at first ill-shapen, so are all innovations, which are the births of time.

To live, we must daily break the body and shed the blood of Creation. When we do this knowingly, lovingly, skillfully, reverently, it is a sacrament. When we do it ignorantly, greedily, clumsily, destructively, it is a desecration. In such desecration we condemn ourselves to spiritual and moral loneliness, and others to want.

I'm trying to figure out the biology of dinosaurs and what they were like as living creatures.

When a man has pity on all living creatures then only is he noble.
