indemonstrable การใช้

• Our own doctrine is that not all knowledge is demonstrative : on the contrary, knowledge of the immediate premises is independent of demonstration . ( The necessity of this is obvious; for since we must know the prior premises from which the demonstration is drawn, and since the regress must end in immediate truths, those truths must be indemonstrable . ) Such, then, is our doctrine, and in addition we maintain that besides scientific knowledge there is its original source which enables us to recognize the definitions . | Aristotle | " Posterior Analytics"
