They delude us more than they teach us, and bring us but uncertain and fugitive images.

This outward mutability indicated, and did not more than fairly express, the various properties of her inner life.

这种外在的易变性表明，但只是公平地表达了她内心生活的各种性。

Thus just as earlier theories have explained the mobility of the continents, so hot spots may explain their mutability (inconstancy).

因此，正如早期的理论解释了大陆的流动性，热点也可以解释它们的易变性（不稳定性）。

THOSE unconvinced-and those seeking to unconvince others-of the reality of man-made global warming often point to the changeable behaviour of the sun as an alternative hypothesis.

不相信全球变暖是人为因素造成的和那企图让别人不相信的人常常会的易变表现作为假设进行选择。

It could be because of greater natural variability in the climate, because clouds dampen warming or because of some other little-understood mechanism in the almost infinitely complex climate system.

这可能是因为自然气候有很大的易变性，因为云能减弱温升，或因为在无限复杂的气候系统中有一不为人知的调节机制。

For these reasons perfect stability of prices is impossible in an economy subject to change-unless, indeed, there is some peculiar mechanism which ensures temporary fluctuations of just the right degree in the propensity to consume.

由于这原因，在一个易变的经济体中，价格的完美稳定是不可能的——事实上，除非有某种殊的机制来确保消费倾向的暂时波动恰到好处。
