It may be quite true that some negroes are better than some white men; but no rational man, cognisant of the facts, believes that the average negro is the equal, still less the superior, of the average white man. And, if this be true, it is simply incredible that, when all his disabilities are removed, and our prognathous relative has a fair field and no favour, as well as no oppressor, he will be able to compete successfully with his bigger-brained and smaller-jawed rival, in a contest which is to be carried on by thoughts and not by bites.

The scientific imagination always restrains itself within the limits of probability.

Only one absolute certainty is possible to man, namely that at any given moment the feeling which he has exists.

The world is neither wise nor just, but it makes up for all its folly and injustice by being damnably sentimental.
