Can someone help me understand what the と particle is doing in this sentence?


I'm fairly certain the と particle here is the conditional form. But I could be
totally wrong.

それが真実であると仮定しよう。

The translation I have for it is, "Let's suppose it is true". But it seems odd
to me that と is being used conditionally. Wouldn't it transliterate to
something like, "If it is true, let's suppose"?




This と is a _quotative_ -と, not conditional.

> それが真実であると仮定しよう。  
>  Let's assume that it is true.

A conditional-と cannot be used with (し)よう in the first place. Something like
雨が降ると家にいよう is already ungrammatical.
