in Life's name and for Life's sake

I think it would be rather interesting to see two crazy people attempting to justify themselves to each other, though- talking (or raving or monologuing- yes I verbed it, and I also verbed verb) on two completely different subjects, but still believing they understand each other because everything the other person says is filtered by their own thought process and perception etc. Sometimes I think the world's actually like that- the same way colors could be different for different people? Like we're all walking around completely unaware and thinking we can communicate and connect, but we really only understand what we already know, because we filter things that way. Or something.
