Thread: anything else

I don't believe in anything else except from simple logic

Я не верю ни во что больше чем (в) простой разум!

Я не верю ни во что, кроме обычной логики.

Yours is grammatically correct and definitely understandable, just a bit... dunno, just doesn't really fit. Oh, yes, you need that "в" there.

in anything else = ни во что другое

So we approach iCake's variant, because we should choose the correct correspondence:
другое <-> кроме
больше <-> чем

"другое кроме" can be shortened to "кроме"

Also
"я не верю ни во что больше" is "I do not belive in anything anymore".
compare:
"я верю ему больше, чем когда либо" is "I belive him more than ever".

So, translation in zero-post is not correct in meaning also. It says "I don't believe in anything more than I do belive in simple logic."
