Full Idea
Kant, in his epistemology, turns the issue of scepticism around by acknowledging that, although we can never know things-in-themselves, the objects of our representations conform to the concepts we have of them in a manner sufficient for knowledge.
Gist of Idea

A Reaction
This seems to invite the problem of a brain-in-a-vat, which is fed absurd representations, and set up with a bunch of silly concepts that conform to the representations.
