The theory of evolution must be considered as a scientific theory, as theory, that is, proposed to explain or systemize a set of facts, and that no one has any claim to be considered as a serious rival to Darwin in the "discovery" of this theory who did not conduct his evolutionary studies upon a reasonably wide basis of facts. To have ideas, apercus, is not enough, and it is the overevalutation of such clever but uncontrolled guesses which is apt to produce the ludicrous fallacy of combination, in which fragments of the final theory are collected from widely scattered sources and are combined in such a way as to impugn the originality of him who was the first to see how such a synthesis was possible.
