I found an interesting article about a professor who held a competition to find 'the Worst Argument in the World' based on a) 'its intrinsic awfulness', b) its widespread acceptance and c) the degree to which it has escaped criticism.
Here it is:
We can know things only:
-as they are related to us
-under our forms of perception and understanding
-in so far as they fall under our conceptual schemes etc
THEREFORE,
We cannot know things as they are in themselves
***
There it is, the WORST ARGUMENT IN THE WORLD!
