It has been too often assumed that " proof " must be what kant called " apodeictic " that is of the kind that we used to be familiar within euclid , where the argument could be concluded with a triumphant q . e . d . because every rational person who understands the propositions is compelled to accept the inference 我們常常假定, “證據(jù)”一定是康德所稱之“絕對肯定的” ? ?那種我們在歐氏推論中所熟悉的,那種可以把論據(jù)推演到成功地“證完” ,因為每個懂得命題的具有理性的人都一定會接受那樣的推斷。
