Now, starting from this fiction, it explained, in diametrical opposition to the truth, all that is established by a reason as contingent, because it looked at the relative nature of its necessity and compared this with that entirely imaginary absolute necessity, which is self-contradictory in its conception. Now Kant adheres to this fundamentally perverse definition of the contingent and gives it as explanation. (Critique of Pure Reason, V. p. 289-291; 243. V. 301; 419. V. 447, 486, 488.) He falls indeed into the most evident contradiction with himself upon this point, for on p. 301 he says: "Everything contingent has a cause," and adds, "That is contingent which might possibly not be." But whatever has a cause cannot possibly not be: thus it is necessary. For the rest, the source of the whole of this false explanation of the necessary and the contingent is to be found in Aristotle in "De Generatione et Corruptione," lib. ii. c. 9 et 11, where the necessary is explained as that which cannot possibly not be: there stands in
