The question which then arises is: What is the principle of inference by which we pass from past sunrises to future ones?

那么出现的问题是：我们从过去的日出过渡到未来的日出所依据的推理原则是什么？

The principles of inference are apt to be overlooked because of their very obviousness—the assumption involved is assented to without our realizing that it is an assumption.

推理原则很容易被忽视，因为它们非常明显——所涉及的假设在我们没有意识到这是一个假设的情况下得到了认同。

But it is very important to realize the use of principles of inference, if a correct theory of knowledge is to be obtained; for our knowledge of them raises interesting and difficult questions.

但是，如果要获得正确的知识理论，那么实现推理原则的使用是非常重要的；因为我们对它们的了解提出了有趣而困难的问题。
