Question everything.

How do you know 2 + 2 = 4?

It's only a rule you've been taught.

2 + 2 always = 4.

You wouldn't dare question that. Would you?

Because that's all you know.

You don't know how 2 + 5 could = 4.

It's impossible, you say.

As anyone would agree with you.

But does collective agreement = truth?

Hardly.

So what is real?
