TO R. B. LITCHFIELD, Esq.

                                                                 Trin. Coll., 25th March 1854.

I am experiencing the effects of Mill, but I take him slowly. I do not think him the last of his kind. I think more is    wanted to bring the connexion of sensation with Science to light, and show what it is not. I have been reading   Berkeley on the Theory of Vision, and greatly admire it, as I do all his other non-mathematical works; [208] but I   was disappointed to find that he had at last fallen into the snare of his own paradoxes, and thought that his  discoveries with regard to the senses and their objects would show some fallacy in those branches of high
mathematics which he disliked. It is curious to see how speculators are led by their neglect of exact sciences to put  themselves in opposition to them where they have not the slightest point of contact with their systems. In the   Minute Philosopher there is some very bad Political Economy and much very good thinking on more interesting  subjects. Paradox is still sought for and exaggerated. We live in an age of wonder still.
