“Do not harass the ant that’s dragging a seed, because it has life and sweet life is dear.”
We conceive of the individual animal as a small world, existing for its own sake, by its own means. Every creature is its own reason to be. All its parts have a direct effect on one another, a relationship to one another, thereby constantly renewing the circle of life; thus we are justified in considering every animal physiologically perfect. Viewed from within, no part of the animal is a useless or arbitrary product of the formative impulse (as so often thought). Externally, some parts may seem useless because the inner coherence of the animal nature has given them this form without regard to outer circumstance. Thus…[not] the question, What are they for? but rather, Where do they come from?
