同时，伽达默尔反对历史主义因为他说，人们做不到。

In the meantime, Gadamer is objecting to this because he says, you simply can't do this.

在旧历史主义的思想中，历史是话语或文学的背景。

As it's traditionally thought to be by the Old Historicism, history is a background to discourse or literature.

我会再讲一遍，现在说可能有点早，伽达默尔认为历史主义有些不道德。

I'll say again, somewhat in advance perhaps of the time I should say it, that Gadamer thinks that there's something immoral about historicism.
