Without preconceptions — without having already half-templated and half-mapped the world we are trying to perceive and navigate — we would have to evaluate afresh every smallest object our attention falls upon.

Most facts in consciousness seem to be partly made. A report is the joint product of the knower and known, in which the role of the observer is always selective and usually creative. The facts we see depend on where we are placed, and the habits of our eyes.

For the most part we do not first see, and then define, we define first and then see. In the great blooming, buzzing confusion of the outer world we pick out what our culture has already defined for us, and we tend to perceive that which we have picked out in the form stereotyped for us by our culture.
