真相并不总是最重要的；有时重要的是人们相信什么是真的。
"The truth is not always the most important thing; sometimes, what matters is what people believe to be true."
理论和实践的区别在于，理论上，理论和实践没有区别，但在实践中，却有区别。
"History is always written by the victors, but the voices of the defeated are equally important."
智者的观点是一样的，愚人的观点千差万别。
解释：对于一件事情的利害得失，只有有智慧的人才能分辨清楚。
