how does the author explain the fact that the scientific method, the industrial revolution, and (to use his words), "the multiplicity of artifactual interfaces in a global technoscientific economy" grew out of the Western intellectual tradition?

Whether the industrial revolution came out of the intellectual tradition is up for debate. If you take Henry Ford as of of the core people of the industrial revolution, Ford didn't go to university. I think most of the knowledge that made Ford successful wasn't about him believing in justified true statements but of more implicit nature.

The people who invented the steam engine also didn't have university degrees. They were rather tradesman who relied on mechanical skill for their inventions. Western intellectuals didn't concerns themselves with optimal systems of pumping water out of mines like Thomas Newcomen did.
