“因为这种在好运时变得过度自信,在不幸时变得不足的模式是你的行为习惯和教养的结果. 如果你的教育是愚蠢和软弱的, 那你就会, too; if it was the opposite, 那么你将是相反的. 如果你从小就对这个世界有很好的了解, 这样,你就不会在事情进展顺利时过于兴奋,也不会在事情进展不顺时感到沮丧. If this is true of an individual it is also true of a group of people living in the same state; they have the qualities that result from their society’s habits of behavior" (Machiavelli, 话语, in 政治著作选集 p. 210).
