Good resolutions are useless attempts to interfere with scientific laws. Their origin is pure vanity. Their result is absolutely nil.

To be beneficent when we can is a duty; and besides this, there are many minds so sympathetically constituted that, without any other motive of vanity or self-interest, they find a pleasure in spreading joy around them, and can take delight in the satisfaction of others so far as it is their own work. But I maintain that in such a case an action of this kind, however proper, however amiable it may be, has nevertheless no true moral worth, but is on a level with other inclinations. . . . For the maxim lacks the moral import, namely, that such actions be done from duty, not from inclination.

They are a sign; a sign of insincerity; a sign of suppressed vanity; a pretense that we desire gorgeous colors and the graces of harmony and form; and we put them on to propagate that lie and back it up.
What if God were not exactly truth, and if this could be proved? And if he were instead the vanity, the desire for power, the ambitions, the fear, and the enraptured and terrified folly of mankind?
