remind me what an inductive argument is.

Now let's look at another inductive argument.
现在我们看另一个归纳论点。
Okay. So here's an example of a strong inductive argument.
好，这是一个有力的归纳论点。
That means an inductive argument can be either weak or strong.
这意味着一个归纳的论点可能或弱或强。
That's a strong inductive argument, why isn't that a deductive argument?
这是个有力的归纳论点，为什么不是演绎论点呢？
I mean I can give you an inductive argument like this, in fact let me give you one.
我的意思是我可以给你一个类似的归纳论点，我来说一个。
You mustn't think that deductive argument is certain and inductive arguments aren't.
你不能认为演绎论点是确定的，归纳论点是不确定的。
So there is a gradation, it's a matter of degree or how good an inductive argument is.
这里有一个分级，这是程度的事，一个归纳论点有多好。
Therefore the next time I see Marianne she will be wearing earrings. Is that a strong inductive argument?
所以下次我看到Marianne的时候，她肯定也戴着耳环，这是个有力的归纳论点吗？
An Inductive argument is such that the truth of their premises makes the conclusion more or less probable.
一个归纳的论点中前提的真理，使结论或多或少有可能。
If the premises are true the conclusion must be true and an inductive argument you haven't got certainty you've got probability.
如果前提为真，结论必定为真，归纳论点没有确定性，而有可能性。
Oh ok, I have done it now, I was going to ask you what an inductive argument was but there we are. But you knew this anyway didn't you?
好，我做了，我要问你们什么是归纳论点，但是我们在这，你知道这个，不是吗？
And this one the inductive argument is saying if this is true, then this will be true. Now in this case we can say there is a counter example to this.
这个归纳的论点说如果这是真的，那么这也是真的，现在我们可以说，有一个相反的例子。
So the principle of the uniformity of nature which underlies every inductive argument, which can't itself be argued for because arguing for it takes us in a circle.
所以自然统一性的原则是，每个归纳论点背后，都不能证明自己，因为这是循环证明。
An inductive argument is more or less strong whereas deductive arguments are either valid or invalid. Okay What does an argument have to have in order it to be sound?
归纳论点或多或少有力，但是演绎论点有效无效，什么能说明论点完好？
So those were the tests for an inductive generalization, these were the test for causal generalization, these for the arguments from analogy, and these for argument from authority.
那些是对归纳推广的测验，这些是对因果推广的测验，这些是类比论点的测验，这些是权威论点的测验。
So those were the tests for an inductive generalization, these were the test for causal generalization, these for the arguments from analogy, and these for argument from authority.
那些是对归纳推广的测验，这些是对因果推广的测验，这些是类比论点的测验，这些是权威论点的测验。
