私には versus 私は - difference in nuance?


Can anyone help explaining the nuance in difference between:

私はまったく分かりません。

私にはまったく分かりません。

With expressions such as ヨーロッパには行く (versus は) I can see what affect including
the に particle within the scope of the sentence has (i.e. I will go to Europe
(specifically, likely not anywhere else).

I don't see any difference with 私には, however.

Cheers,

Luke




I feel like in the case of

> 私{わたし} **に** は分{わ}かりません

... the に is there to emphasize that you are referring to an ability or
condition **_within_** yourself (perhaps like you were categorically negating
the idea that you could possibly know). 私は分かりません seems more matter-of-fact,
simply contrasting your knowledge to everyone else's.

This could be similar to the difference between "I don't know" and ("I
wouldn't know" or "I'm not in a position to know").

So you might translate a similar example this way,

  * 彼{かれ}は分からないと思{おも}う - I don't think he knows
  * 彼には分からないと思う - I don't think he would know _or_ I don't think he's in the position to know
