Wish I'd said that - June 12, 2016

How conscience tells us that we ought to be fair, nobody knows. This we can say: we don’t know it just from being told, we don’t know it from the five senses, and we don’t know it by inference from prior knowledge. We just know it. The knowledge is ‘underived.’… How do we know that we exist? No one knows. Not so, you say. I think, therefore I exist. But how do you know that you think? No one knows that either. You just do.”

J. Budziszewski What We Can’t Not Know
