“…she was one of those happily created beings who please without effort, make friends everywhere, and take life so gracefully and easily that less fortunate souls are tempted to believe that such are born under a lucky star.”

Book III, Ch. 8
This quote is a paraphrase of a lengthier statement, as follows: We ordinarily see, in the actions of the world, that Fortune, to shew us her power in all things, and who takes a pride in abating our presumption, seeing she could not make fools wise, has made them fortunate in emulation of virtue; and most favours those operations the web of which is most purely her own; whence it is that the simplest amongst us bring to pass great business, both public and private; and, as Seiramnes, the Persian, answered those who wondered that his affairs succeeded so ill, considering that his deliberations were so wise, ‘that he was sole master of his designs, but success was wholly in the power of fortune’; these may answer the same, but with a contrary turn.
