"Is" and "Are" seem to be some of the most annoying words in the English language. What they do, they allow us to think that whatever relationship we connect between the two concepts, IS true.
For instance, this post IS redundant. Instantaneously, we shift from No Opinion to The post IS for all certainty and all eternity until I say so, redundant.
However, there is no "is." "Is" is a made up term. See how I connected it there? To me Is suddenly becomes... a made up term, for me.
We tend to forget, that additional part, "for me".
Anyway, the way we say something IS something or somethings ARE something gives a tone a definition, of certainty, of truth, of correctness. We say something IS and if we are contradicted we rebel, because after all what we just said IS something, and that IS right. Because it IS.
Because, of course, we tend to think in language. I don't think we are all to the point that we all communicate in a symbolic, picture-based, and easily adaptable language, simply because we can't really do that yet. We don't all seem to be telepaths, and it becomes mighty unhandy to lug around a sketchpad and pen, drawing every little thing, idea, or thought you have pictorially. Like, "The day is nice." To you, of course it is! It's sunny, shining, the humidity is nice, you just had a wonderful breakfast and you don't have to do anything! (Technically you never HAD to do anything; it's just like IS in its arrogant certainty.) But to another person who woke up to "So-and-so country (that your spouse is vacationing in) is having major uprisings, all airports have been shut down due to violence" and little sleep and a hangover and is extremely constipated (oops, there's "is"), to this person they are having, a Terrible day. So when you say, "The day is nice" they have perfect reason to contest your point of view, and say, "No it's not." You, in your ignorance and lack of attachment to their situation, say, "Well, I think it is, I mean just look, it's really nice!" And they give you a sulky glare and walk off, with you saying, "Wait, what's wrong?" in hopes of trying to find out where the discordance in opinion lies, so that it may be resolved, preferably in your favor.
And don't get me wrong, I have actually seen (unless I've been hallucinating these past fourteen years) people argue about whether or not the day is nice. I want to say, Look, everyone's situation is different, and your perspectives will not agree, as they are (oops) not necessarily coming from the same angle!
What was the point I was trying to get across here? Well, I suppose it was simply a restatement of "There are no absolutes," nothing necessarily... is.
