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,提醒和強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。
