(as well as of bringing in foreign materials), we represent to ourselves a mechanical mode of producing it.

But in this way no concept emerges of a whole as purpose, whose internal possibility presupposes throughout the Idea of a whole on which depend the constitution and mode of action of the parts, as we must represent to ourselves an organised body.
