Quine's classic essay "The Ways of Paradox." There, Quine classifies paradoxes as "veridical" and "falsidical
" paradoxes and "antinomies." Since "veridical" paradoxes turn out to be simply cleverly put banalities (someone who was born on February 29 can be 21 after only 5 birthdays) and "falsidical
" ones can be proven to be based on fallacies (Quine's example is the proof that 2 = 1 based on a division by 0), the only "real" paradoxes turn out to be the antinomies, the kinds of paradoxes that produce the conclusion that something is and is not.
