Epicurus knew and even Aristotle was aware of that binary logic might be applicable in full only to timeless sentences and those which refer to past events but not to events in the future.
YES - that is the issue, and I think it's absolutely critical that people understand that before, during, and after they try to absorb the presentation, because otherwise the problem diagnosed in the Hermotimus excerpt is undetectable.
Do you have any specific references on those two categories (1) timeless sentences (2) future events?
I believe part of what you are referring to must include the Epicurus reference to not being willing to state whether Hermarchus will be alive or dead tomorrow.
And this comment is not directed just to Martin - everyone who is at all interested in this issue needs an understanding of this, so we need to develop means of explaining it that are as memorable as possible.
