Oh yes, the picking apart of the butterfly.
That always bothered me about the reductionist fashion. If you
pin a butterfly to a board and dissect it, you're not dissecting
a butterfly; the butterfly is gone the moment you kill it.
it's not that you can't learn a lot by stacking jigsaw pieces
but its value is limited and is really unrelated to the purpose
and nature of the thing-in-itself.
