Assumptions in Science

By -
Over at Unqualified Offerings, Thoreau writes:
"In a continuing effort to highlight the way that even the most fundamental assumptions are subject to experimental testing in science..."

This, of course, logically cannot be the case. How, for instance, could the fundamental assumption that experimental testing is a good way to get at the truth be tested experimentally without logical circularity? Or the idea that their is some sort of quantitatively stable relationship between a sequence of measurements? (You have to simply assume this, or all of your measurements are merely random pokes in the dark that prove nothing.)

"Pre-Galilean" Foolishness

 I am currently reading The Master and His Emissary , which appears to be an excellent book. ("Appears" because I don't know the neuroscience literature well enough to say for sure, yet.) But then on page 186 I find: "Asking cognition, however, to give a perspective on the relationship between cognition and affect is like asking astronomer in the pre-Galilean geocentric world, whether, in his opinion, the sun moves round the earth of the earth around the sun. To ask a question alone would be enough to label one as mad." OK, this is garbage. First of all, it should be pre-Copernican, not pre-Galilean. But much worse is that people have seriously been considering heliocentrism for many centuries before Copernicus. Aristarchus had proposed a heliocentric model in the 4th-century BC. It had generally been considered wrong, but not "mad." (And wrong for scientific reasons: Why, for instance, did we not observe stellar parallax?) And when Copernicus propose
