市场是人性的反映，而人性永远不会改变。
The market is a reflection of human nature, and human nature never changes.
The value of a commodity, or the quantity of any other commodity for which it will exchange, depends on the relative quantity of labor which is necessary for its production, and not on the greater or less compensation which is paid for that labor.
我们对明天的唯一限制是我们今天的疑虑。
The future is hidden even from those who make it.
