To realize that we have a splinter in our eyes is the first step, I think. The rest I just percolate like so: As Diane Ackerman said, we live on the leash of our senses. To recognize that our senses lie to us, and still recognize that the world they present is really the only view the world that we have -- then we can appreciate the truths our senses tell us. Then there's the social dimension -- perhaps truth can be found in the mean of many perceptions, if we'd share them. With that input, we have distilled our inner selves with the knowledge (or exposure to) many paradigms -- and by comparison and contrast with each other it creates enormous confusion that eventually gives way to understanding. Least, that's how I find it.
