Opposites not both true


Heads or tails, can you spend the coin?


If that is supposed to refute that opposites are not both true, you'll have to explain to me how.  Thanks.

you'll have to explain to me how

 

      While heads and tails of a coin are opposites, the essence of the coin is independent of its sides. So, no matter if heads of tails show; it's still a coin.

 

      The truth or falsity of a proposition requires an application. To kill someone with a weapon is murder but to kill the enemy in combat is a good thing. Both killings are killing, plane an simple, the discriminator is the application.

Ok.  I don't see any problem with what you said and I don't think it goes against the argument I put forth.  I didn't really offer a proposition regarding a coin.  That was something you brought up and I wasn't sure if you were using that to say that opposites cannot both be true (at the same time and in the same way, as stated at the very beginning of the thread).  If I were to offer a proposition regarding the coin, I would say that the statements "The coin is heads up" and "The coin is tails up" cannot both be true at the same time and in the same way.  Anyway, thanks for clarifying what you meant for me.
