Letter 121 — On Instinct in Animals (§23)

“This art is born, not taught; and for this reason no animal is more skilled than any other. You will notice that all spider-webs are equally fine, and that the openings in all honeycomb cells are identical in shape. Whatever art communicates is uncertain and uneven; but Nature’s assignments are always uniform. Nature has communicated nothing except the duty of taking care of themselves and the skill to do so; that is why living and learning begin at the same time.”
