[O]nly if every individual strives for truth can humanity attain a happier future; the atavisms in each of us that stand in the way of a friendlier destiny can only thus be rendered ineffective.
O Voltaire! O humanity! O idiocy! There is something ticklish in "the truth," and in the SEARCH for the truth; and if man goes about it too humanely-"il ne cherche le vrai que pour faire le bien"-I wager he finds nothing!
The truth is, of course, that the curtness of the Ten Commandments is an evidence, not of the gloom and narrowness of a religion, but, on the contrary, of its liberality and humanity. It is shorter to state the things forbidden than the things permitted; precisely because most things are permitted, and only a few things are forbidden.
Our chief usefulness to humanity rests on our combining power with high purpose. Power undirected by high purpose spells calamity, and high purpose by itself is utterly useless if the power to put it into effect is lacking.
