“The burden of freedom, the responsibility of finding—or creating—one’s own purpose and meaning without the guidance of authoritative, inherited creeds and values, is too heavy for all but a few. The rest of us cannot endure for long the tensions of uncertainty. We must, at some point, stop questioning, quiet our doubts, turn away from moral and metaphysical inquiry and toward life. Untrammeled skepticism ends in paralysis. This is true of societies as well as of individuals. No purely rational justification can be offered for trust and self-sacrifice. But without them, social life is chaos, a war of all against all.”
