We persuade ourselves we can live with our sins...

我们说服自己 我们能原谅自己的罪过。

Now what makes it natural to call this principle a law of thought is that it is by thought rather than by outward observation that we persuade ourselves of its necessary truth.

现在，将这个原则称为思想法则是很自然的，因为我们是通过思想而不是通过外在观察说服自己相信它的必要真理​​。

If, however, this were the source of our knowledge that two and two are four, we should proceed differently, in persuading ourselves of its truth, from the way in which we do actually proceed.

然而，如果这就是我们关于二加二等于四的知识的来源，那么我们在说服自己相信它的真实性时，应该不同于我们实际进行的方式。
