I have a question about the sentence as below:

Let me assure you, you gentlemen who sit comfortably in your armchairs and attribute no worthy motives to us climbers, that there is something more than self-satisfaction in placing our feet upon a summit where no foot has ever trod before.

I didn’t understand the part “attribute no worthy motives to us climbers” of it very well. To attribute is a difficult word for Japanese because we hardly say in such a way. If I take a part of them which I didn’t understand as a full sentence, it is that “You attribute no worthy motives to us climbers.” I name it as (A).

From the cite of Longman Dictionary,
attribute something to somebody/something:
to believe or say that someone or something has a particular quality.

There is an example sentence, (B)“One should not attribute human motives to animals.” I didn’t understand this meaning, but I assumed that this example is used in the same way as the above sentence (A).

Could you say (A) or (B) in other easy words?
