What about things which are true some of the time and not others?
Like, if I was observing the behavior of subatomic particles, and I declared "This electron exists in this location," and then as soon as I said it it changed location. Or in the process of me saying it it changed location. What I said was true at the time that I said it, but if I were to make the statement a few seconds later it would not be true. Of course you could talk about creating equations describing their paths as a function of time, and using them to make predictions. Or what about something entirely subjective like love: Love is both pleasant and unpleasant. Being in love is easy some of the time and hard other times. So are the statements "love is easy" and "love is difficult" contradictory?
I know, I'm not using hard logic here. Just throwing things out. I'm really just asking questions, not pretending I have answers.
