premise is an idea or theory on which a statement or action is based. 在逻辑上,我们程之为前提。
evidence is one or more reasons for believing that something is or is not true.即“证据“

在推论中,我们依据前提premise,利用证据evidence来证明自己结论。

Thanks  a lot,

Still a little confused about the difference between premise and evidence.
Are there any example for them?

请看小安Boldface的 第七题:

7. To be accepted as a member at the Brown Country Club, one must have a net worth of over ten million dollars and must not have any connections to the entertainment industry. Robert Chase, the publishing magnate, has a net worth of 5 billion dollars and chase has not financed any Hollywood movies, so he must be accepted as a member at the Brown Country Club.

The two portions in boldface play which of the following roles?

(A) The first is the part of evidence in support of this argument; the second is the conclusion that could not be drawn from all evidence that the argument contains.
(B) The first is the first-evidence that supports this argument; the second is the mainpoint that must be drawn from all evidence that the argument includes.
(C) The first is the one fact of two that argument includes; the second is the conclusion that could be drawn from this passage.
(D) The first is the background that is necessary for this argument; the second is the conclusion that is not drawn only from the first.
(E) The first is the cause that the argument includes; the second is the effect that can be drawn only from this cause.

我觉得To be accepted as a member at the Brown Country Club, one must have a net worth of over ten million dollars and must not have any connections to the entertainment industry. 就是一个premise  (有待指正)

而Robert Chase, the publishing magnate, has a net worth of 5 billion dollars and chase has not financed any Hollywood movies 就是一个evidence.
Answer is  A.

另外,综合前辈们的论述:principle 是一个常理, 比如 boldface #1 :During landing, navigation systems receive radio signals from the airport to guide the plane to the runway. Fact 是一个事实,通常是已发生的, 并且这个事实会在论述中被论据提到的,
所谓引经据典。 比如 boldface #8 : Over the past several years, however, the advance of electronic media, particularly CD-ROMs, online computer services, and the Internet, has made 9information available to the public electronically without the need for printed materials. 而之后的论据就提到了这个fact:As the availability of electronic media increases and as it is more easily accessible, the public has less need for printed materials.
所以,我们不能说fact 是一个论据,因为她是一个事实。

希望讲清楚了!

我怎么觉得,在推理中称为前提,在论证中称为论据。


逻辑书上是这么定义的:


推理就是从一个或者若干个命题得出其他命题的思维过程。它由前提和结论两部分组成。推理所依据的命题,叫做前提;通过推理所得到的命题,叫做结论。


论证:用一个或几个已确定为真的命题,进而去确定另一个命题的真实性的思维过程,就是论证。
