“Unquestionably society ought to be so organised as to render self-sacrifice superfluous, for as long as men exist who are ready and willing to make sacrifices, so long will egoists take advantage of these sacrifices.”

Section 47
The True Believer (1951), Part Three: United Action and Self-Sacrifice
Context: Glory is largely a theatrical concept. There is no striving for glory without a vivid awareness of an audience—the knowledge that our mighty deeds will come to the ears of our contemporaries or "of those that are to be." We are ready to sacrifice our true, transitory self for the imaginary eternal self we are building up, by our heroic deeds, in the opinion and imagination of others.

The Walk With God (1919)
Context: There is no hell like that of a selfish heart, and there is no misfortune so great as that of not being able to make a sacrifice. These two thoughts come to me strongly this morning. It is something to have learned these truths so that we can never again doubt them.
