TO define anything in these days is an unpopular task. To define is to limit, and we are to-day impatient of limits of any kind. The vast expansion of our outlook resulting from a world-shaking political upheaval has reacted upon our social, our economic and our philosophic thought. We respond as seldom before, to every manner of high, generous, broad, liberal suggestions. We repel as unworthy of such spacious days whatever suggests narrowness, commonplaceness, selfishness. We forget easily that breadth may be purchased at a sacrifice of depth, loftiness at the price of a solid footing upon the earth, and generosity by throwing away the things that make us strong for righteous dealing.
