Consensual Reality

I have heard from quite a number of people over the past couple of years, this idea that "you can't know anything" therefore it's all meaningless. Usually people throw that sort of concept out without ever explaining it. It sounds nihilistic, doesn't it? I've heard this from a philosophy professor, but also from normal people who don't seem to be able to explain what they are saying. Often it seems reactionary.

I've always had a problem with this school of thought, but I've never been able to really wrap my head around why, and what I thought was the more accurate way to look at the world.

But lately, I've formed this idea of reality that I thought I'd share with you. I've never taken a philosophy class, so excuse me if it sounds silly.

Ok, if I say "finger", most of us on the planet know what I am talking about. You can lift your finger triumphantly in the air and waggle it about. You can touch your keyboard with it. Even babies can learn what a finger is and how to use it to pick their noses and do other fun things.

Language helps us form a consensual reality. This reality is basically universal. For instance, I can say "love" and translate that into Japanese, and a Japanese person can get the general idea of what I am talking about. If I form a sentence, "I love my child", that other person on the other side of the planet can relate to that statement and agree or disagree.

Consensual reality has often been explained as "if enough people believe something, then it's real." This is not necessarily true. For instance, most people believe in a deity, but there is no evidence of anything supernatural, so most people are probably wrong. But just about everyone knows that water is wet, and they are correct.
