Nearly all the great philosophers of the English tradition have been in this sense popular writers, though I am afraid that the same cannot be said of the Germans. The style of Locke is lucid, if pedestrian; of both Berkeley and Hume beautiful in the extreme; of Mill clear and simple, though undistinguished and marred by some affectations; of Spencer perfectly lucid in spite of the "hurdy-gurdy monotony of him." William James, the greatest of American philosophers, had an absolute genius for graphic, telling, and brilliant English phrases. And of living writers, as I have already said, Mr. Russell's style is the best, and is a standing example of the fact that philosophy, and original philosophy too, can be written in plain English with an absolute minimum of technical terms.
