Introspection, as a separate source of knowledge, is entirely denied by psychologists of this school.

内省作为一种独立的知识来源， 被该学派的心理学家完全否定。 我将在以后的讲座中详细讨论这个问题。

They deny altogether that there is a separate source of knowledge called " introspection, " by which we can know things about ourselves which we could never observe in others.

他们完全否认存在一种称为“内省” 的独立知识来源， 通过它我们可以了解我们永远无法在他人身上观察到的关于我们自己的事情。
