对(right/ correct) is an extended meaning of 然 e.g. 然也 = 正是如此 = it is exactly so --> it is correct. But the meaning of 'correct'  doesn't fit this context, EEQ's answer is the correct one

@TangHo I think grammatically the sentence could be interpreted either way, though it's always been interpreted the other way as the answer shows. I just updated my answer.

Apparently, 所以然 means "the reason why" (or some variation thereof) according to several dictionaries on Pleco. Furthermore, one definition of 所以 itself (as per Xiandai Hanyu Guifan Cidian) is "实在的情由；适宜的言行举止". I would take this as further evidence that 然 does indeed mean "这样" (or some variation thereof) in both places in this sentence and as per EEQ's answer.

@Pedroski The context was fine. 知其然而不知其所以然(and variants) is an established and commonly used phrase, with two parts  that can each be used on their own. Since you know that 所以然 means 所以如此, it should be evident that 然 means 如此。

I was more curious about why you think the two 然 have different meanings (as implied by your question). As of the meaning of 然, well you get the gist anyway, but consider this: if 然 means “right”, what exactly is being referred to as right in this sentence?

### Answer by username_3 on 2022-08-10. Score: 0 | Accepted answer

然 means 对(right). The whole sentence means *know it's right and why (it's right).*

P.S. The sentence could be interpreted either way.

知其然还要知其所以然

知: to know

其: it (它)

然: (according to dictionaries, it could mean:) pron. 这样 or adj. 对

It could make sense to interpret it as

知/其/然: 知道/它/这样 or 对.

I would take either 知道它对 or 知道它这样 as a possible interpretation given the sentence standing alone.

知其所以然 means either 知道它为什么这样 or 知道它为什么对.

Note: I might be in minority group here since most of people would only take the other interpretation as the only possible one.
