"the incorrigibility thesis", The thesis that it is logically impossible to be mistaken about such things as whether I am now in pain or am seeing or seeming to see something red, Is very widely supposed to be false. I consider the arguments designed to show this, And argue that they all fail.

If I am looking at myself in a mirror I am directly facing, do I see myself looking at myself? If so, do I also see myself looking at myself looking at myself – and so on?
