Absolute power can only be supported by error, ignorance and prejudice. - Philip Dormer Stanhope

As your affection for me can only proceed from your experience and conviction of my fondness for you (for to talk of natural affection is talking nonsense), the only return I desire is, what it is chiefly your interest to make me; I mean your invariable practice of virtue, and your indefatigable pursuit of knowledge. Adieu! and be persuaded that I shall love you extremely, while you deserve it; but not one moment longer.

A pleasing figure is a perpetual letter of recommendation.

Chance favors the prepared mind.
