For it is a matter of daily observation that people take the greatest pleasure in that which satisfies their vanity; and vanity cannot be satisfied without comparison with others.
Yet some natures are too good to be spoiled by praise, and wherever the vein of thought reaches down into the profound, there is no danger from vanity. Solemn friends will warn them of the danger of the head's being turned by the flourish of trumpets, but they can afford to smile.
The alchemists spent years in their laboratories, observing the fire that purified the metals. They spent so much time close to the fire that gradually they gave up the vanities of the world. They discovered that the purification of the metals had led to a purification of themselves.
Whether a man hides his bad qualities and vices or confesses them openly, his vanity wants to gain an advantage by it in both cases: just note how subtly he distinguishes between those he will hide his bad qualities from and those he will face honestly and candidly.
The majority of mankind is lazyminded, incurious, absorbed in vanities, and tepid in emotion, and is therefore incapable of either much doubt or much faith.
