People seem to miss this a lot, yet we could claim every single thing is "undefined". Even physics is undefined. There's no grand theory of everything. But we still have some really good models. Our models now are a lot better than they were 100 years ago and even more than the 100 years before that and so on.
I abhor people who make the claim that words they didn't spend the time to understand are meaningless simply because they are incomplete. It is idiocracy masquerading as intelligence. I hate it so much because the logic doesn't just fool the listener, it fools the speaker.
