對比語言與邏輯更容易看到邏輯學的空洞之處。

I never studied logic, but I still learnt math and physics well, and learnt them joyfully too.

Yet there is no way I could do that with a language.  I must acquire a language before I can compose an essay in it.

Which proves that the capability of working with logic is automatic and requires no external forms as a language does.

吾不是反對邏輯學，作為總結、歸納，提醒和强化一下邏輯的作用還是有意義的。但不能本末倒置，作繭自縛。
