Aristotle - index for METAPHYSICA Book 11 Part 5

The same thing cannot be and not be

Paragraph 1 There is a principle in things, about which we cannot be deceived, but must always, on the contrary recognize the truth, - viz. that the same thing cannot at one and the same time be and not be, or admit any other similar pair of opposites.

Paragraph 2 Further, if the word signifies something and this is asserted truly, this connexion must be necessary;

Paragraph 3 While, then, there is no proof of these things in the full sense, there is a proof which may suffice against one who will make these suppositions.
