Logic of Events
The second does not spring out from the first directly; but firstness looked at from a second point of view gives birth to a thirdness and the secondness comes out of the thirdness. This is the true logic of events.
It is true that the whole universe and every feature of it must be regarded as rational, that is as brought about by the logic of events. But it does not follow that it is constrained to be as it is by the logic of events; for the logic of evolution and of life need not be supposed to be of that wooden kind that absolutely constrains a given conclusion. The logic may be that of the inductive or hypothetic inference.
