ABSTRACT
Before bringing the criticism on Darwin’s theory to a close, it may not be out of place to make some observations on the law of “Evidence,” and on the quality, and quantity, of the evidence required, to substantiate such a theory as that of Natural Selection. Evidence then in its most general sense, is a witness which establishes or has a tendency to establish, any given facts or conclusions. There are three sorts of evidence all of which more or less cut into one another, but for purposes of classification, and departmental use, may be distinguished as follows: mathematical, moral, and legal. Mathematicians are nearly always good masters of evidence, their very training makes them so, in whatever field of thought or action their testimony may be requisitioned. The control of species by the struggle for existence is so obvious, that no evidence is needed for its corroboration.
