• • Public Schools Are Black Holes, Don’t Drop Your Child into One 
Butler Shaffer, Market Oracle Egoism  | Our prior learning has the dual nature of both informing and constraining our inquiries. Heisenberg’s "uncertainty principle" reminds us that the observer is the observed; that what we see is filtered through the lenses of what we have seen previously; that our prior experiences provide the categories and other concepts with which we define the present. This is why – contrary to the faith of the Objectivists – we can never be certain that what we know and observe comports with "reality." That our learning may, in fact, be identical with "reality" does not overcome the inherent and inevitable character of the subjective nature of what we know. Such an awareness compels us to refine the Cartesian proposition "I think, therefore I am," into "I think that I think, therefore I think that I am."   Published: 2013-01-29
