Silence: A trick of the human gullet that conceals weakness or emptiness.
Sheeny: A Jew who has more money than you have.
Shoal: Shallow, literary, theological. (By extension, Columbia, Harvard, Yale and some other universities are sometimes called shoal-marks.)
Sincerity: 1. A mental attitude acquired after long practise by man, in order to conceal his ulterior motives. 2. To be childish, to be senile. 3. To lack invention, imagination or character. (A sincere man is one who bluffs only a part of the time.)
Sin: Perverted power. The man without capacity for sin has no ability to do good—isn't that so? His soul is a Dead Sea that supports neither ameba nor fish, neither noxious bacilli nor useful life.
