I agree with you say but I just want to emphasize how much that is NOT what Adams says in his book.

In the book, he dismisses science because it's just looking at things and our eyes can deceive us (he uses the example of thinking the earth was flat).

At the same time, he calls for expanding our "perception" of the world. But the many, many ways in which science/technology have legitimately expanded our perception of the universe are dismissed by him, because it's all "just looking at things." A readout of a signal from a radio telescope is just looking at things with our fallible eyes. A measurement of the voltage of a battery is just looking at a readout of a voltmeter.

That is what is supremely frustrating with his view of science.
