Cognition arises out of emotion, not the other way round. Abstraction literally means something that has been ‘dragged away’ from the context in which it lies, as if one were able to pull the bones out of a body. And abstraction is fine – for an intermediate process. But, to be of any use, what is abstracted must live once more: it has to be returned, as if the sinews, flesh and blood were given back to the bones.
