Single Idea 23917
[filed under theme 2. Reason / B. Laws of Thought / 3. Non-Contradiction
]
Full Idea
Contrary things can be reasonably held …because the contrary positions will stand if what is said is true in one way, but not true in another.
Gist of Idea
Contrary statements can both be reasonable, if they are meant in two different ways
Source
Aristotle (Eudemian Ethics [c.333 BCE], 1235b17)
Book Ref
Aristotle: 'Eudemian Ethics', ed/tr. Reeve, C.D.C. [Hackett 2021], p.113
A Reaction
My strategy here is to clarify the unambiguous underlying propositions which are being expressed. There will then be either agreement, or flat contradiction.
