Descartes pointed out that, since our senses can be fooled without our being able to know the difference (e.g. dreams, hallucinations, etc.), there is no way to objectively demonstrate that what we see, hear, etc. corresponds to an external "reality" in any way. Therefore, all observations made by use of our senses (including scientific observations) are suspect. We must take the existence of the world on faith. All we can know for certain is that which we experience directly, without use of our fallible senses -- i.e. our own existence. Cogito, ergo sum.

You might think that. I think that's a bunch of philosophy. I avoided philosophy (successfully) through 12 years of college (sociology and economics too).

I prefer science; that is, fact and theory.

Goodnight.
