Metaphorically, Tom said, if you take knowledge as light, and ignorance as dark, there does sometimes seem to be a real presence to the dark -- to ignorance. Something more tactile and muscley than just lack of knowledge. A sort of will to ignorance. It would explain some politicians.

The test of a sword is not its polish but its temper

A tree is alive, and thus it is always more than you can see. Roots to leaves, yes-those you can, in part, see. But it is more-it is the lichens and moss and ferns that grow on its bark, the life too small to see that lives among its roots, a community we know of, but do not think on. It is every fly and bee and beetle that uses it for shelter or food, every bird that nests in its branches. Every one an individual, and yet every one part of the tree, and the tree part of every one.

I like it that order exists somewhere even if it shatters near me.

The book answers questions other people have thought of. I have thought of questions they have not answered. I always thought my questions were wrong questions because no one else asked them. Maybe no one thought of them. Maybe darkness got there first. Maybe I am the first light touching a gulf of ignorance.Maybe my questions matter.
