"Now, as a final word, I wish to draw attention to the strange use made of these revelations of science in respect to the causal dependence of our elemental sensations upon physical energy, even by so sane an author as the Hon. Bertrand Russell, who in his delightfully lucid manual, entitled The Problems of Philosophy, bases his whole disquisition upon the possible inference that the table in his room does not exist at all, because it varies in shape, in size, in shade or colour as you look at it from different positions and distances, or in different lights. In this admission, he either completely ignores the revelations of science in respect to the meaning, genesis and modus operandi of the senses, or he deliberately flings the canons of inductive logic to the winds."
