A Pilgrim at Tinker Creek is a nice piece of nature writing that is more immanent than transcendentalist in its sentiment; a work more in line with Heraclitus and Dogen than Plato, Emerson, or Thoreau. Dillard strives to appreciate the beauty in the brutality of nature, moving from a scientific understanding and going down into nature, frolicking through the pond scum and detritus to find the beauty in sexual cannibalism and parasitic matricide.

There's a sort of cringe cliché of associating authorship and expression of ideas as equivalent to childbirth. It goes back at least to Plato and Socrates. Socrates called his method of questioning the maieutic method, likening himself to a midwife drawing out ideas. In one of my favorite passages, Dillard subverts this sentiment with an example of ichneumon wasps:

You are an ichneumon. You mated and your eggs are fertile. If you can't find a caterpillar on which to lay your eggs, your young will starve. When the eggs hatch, the young will eat any body in which they find themselves, so so if you don't kill them by emitting them broadcast over the landscape, they'll eat you alive. But if you let them drop over the fields you will probably be dead yourself, of old age, before they even hatch to starve, and the whole show will be over and done, and a wretched one it was. You feel them coming, and coming, and you struggle to rise...
