Is it really a table?

So, you I used to have a pretty good grip on what exactly physical objects were. When I see a pencil, it's a pencil. When I see a desk, it's a desk. And, as goes the great saying, if it looks like a duck, and quacks like a duck, it's a fucking duck....Well that might not exactly be very famous. A friend of mine said it once and he was pretty drunk. Could have been a great man, so if it was, I credit him. Hell, I think my drunk friend is a great man anyway.

Anyways, so, a table is a table right?
WRONG.
The truth of it actually is, that we have absolutely no right to call just any table that we see, a table. What petty attributes do we give such objects? A flat circle, oval, square, or rectangle surface? Four legs? Solid material? For all we know, this could all be bullshit. Because the real truth is that we know nothing about what a table actually is. Somewhere out there, there is a great, all-seeing table that is the true definition of a table. It is the absolute truth of what a table actually is. The tables that we know, love, cherish, and possibly take for granted, may be nothing like tables at all.

I attribute this realization to two people. The first is Plato. What a guy. Plain and simple, he was the one who said this. He discussed absolute truth, this absolute truth being that the things we may think to be facts (lol, oxymoron there) may not be anything like we perceive them to be at all. This is because somewhere out there, there is an ultimate being of that object or idea, that puts all impostors, such as these so-called tables, to shame.
The second person I credit my realization to would be my western civ professor. She explained this to me and acted just crazy enough while doing to convince me to give it some consideration.
I didn't give it too much thought. It's a fucking table for christ sakes.
