5. Theory of Logic / D. Assumptions for Logic / 1. Bivalence

23484	Bipolarity adds to Bivalence the capacity for both truth values [Morris,M]
	Full Idea: According to the Principle of Bipolarity, every meaningful sentence must be capable both of being true and of being false. It is not enough merely that every sentence must be either true or false (which is Bivalence).
	From: Michael Morris (Guidebook to Wittgenstein's Tractatus [2008], 3D)
	A reaction: It is said that early Wittgenstein endorses this. That is, in addition to being true, the sentence must be capable of falsehood (and vice versa). This seems to be flirting with the verification principle. I presume it is 'affirmative' sentences.
