# The difference between ～ようだ, ～ように見える, ～ように思える and ～みたい

In a Japanese English grammar textbook, "seems" is translated as ～のように見える, for example:

He seemed to have been ill.

I've also seen "seems" written as ～（の）ように思える in various example sentences on Space ALC:

It doesn't seem to have an effect.

What's the difference in meaning and usage between ～（の）ようだ, ～（の）ように見える, ～（の）ように思える and ～みたい?

Notice that 見える here is not literally "see" but is a metaphor. –  user458 Jun 11 '12 at 0:17
@sawa Perhaps, but when I page through instances of ように見える in both Eijiro and the Tanaka Corpus, nearly all examples pertain to something perceived visually. While I certainly would not be surprised if metaphoric instances existed, is it possible that ように見える is more likely to be associated with visual observations? –  con5013d Jun 11 '12 at 3:15
Maybe. If so, then you aleady have partial answer to your question. –  user458 Jun 11 '12 at 3:32
