Certainty is possible, but it is a possible kind of certainty: We must form our concept of certainty based on the real needs and abilities of real human minds.
In this recorded webinar, presented on April 30, 2012, Alexander R. Cohen shows what certainty is and how we can attain it. Drawing on the Objectivist theory of concepts, he discusses justification and standards of proof. He explains the differences between possibilities and non-possibilities, and between each of these and impossibilities.
