古希腊的苏格拉底说， “要是得不到自己想要的，人会痛苦。要是得到自己不想要的，人也痛苦。就算在得到自己完全是最想要的，人还是痛苦因为他无法永远地紧握。你看一个人的起心动念就是痛苦之源。人都不爱变化，不喜欢痛苦，更不乐意生老病死。然而，变化却是自然规律。无论如何视而不见也无法改变这一事实。”
"If you don’t get what you want, you suffer; if you get what you don’t want, you suffer; even when you get exactly what you want, you still suffer because you can’t hold on to it forever. Your mind is your predicament. It wants to be free of change. Free of pain, free of the obligations of life and death. But change is law and no amount of pretending will alter that reality." — Socrates
