First published in 1873, this is probably the best-known work of this 19th Century English artist, art critic and author. I propose, in the following pages, to consider the possibilities of a satisfactory intellectual life under various conditions of ordinary human existence. It will form a part of my plan to take into account favorable and unfavorable influences of many kinds; and my chief purpose, so far as any effect upon others may be hoped for, will be to guard some who may read the book alike against the loss of time caused by unnecessary discouragement, and the waste of effort which is the consequence of misdirected energies. The essence of the book may be expressed in a few sentences, the rest being little more than evidence or illustration. I have written for all classes, in the conviction that the intellectual life is really within the reach of every one who earnestly desires it.
