The piece is mumbo-jumbo. Yes, Bacon eschewed the "Aristotelian" search for final causes. Does that mean that Baconian science doesn't try to determine the truth? Of course not.
The history of philosophy/history of science done in this piece is clap trap. He says that Galileo used experiment, whereas Aristotle did not. And that's why Aristotle thought that "heavier objects should fall faster than light ones". Supposedly. The problem: Aristotle didn't use "abstract reasoning" to come to that incorrect conclusion. He just didn't control his variables adequately. Not controlling variables adequately can happen to the very best of experimentalists.
"Science is not the pursuit of capital-T Truth. [...] Scientific knowledge is not "true" knowledge, since it is knowledge about only specific empirical propositions"
So how does this argument run? Scientific knowledge is knowledge about specific empirical propositions. Therefore, scientific knowledge is not "true" knowledge. Therefore, science is not the pursuit of capital-T Truth? That's a terrible argument. This seems like just a case of begging the question from the author where he has an unargued "definition" of what "Truth" is. Why anyone else is beholden to this definition, of course, is a mystery.
"Bacon, who had a career in politics and was an experienced manager, actually wrote that scientists would have to be misled into thinking science is a pursuit of the truth, so that they will be dedicated to their work, even though it is not."
I highly doubt Bacon ever said this. Of course, there is no citation to check. I think the author has confused Bacon's model of Bensalem, where he has the houses of specialists hide their operation from others, so that the others don't come to conclusions based on partial understandings, before the work of the specialists is completed.
"by definition, religion concerns the ultimate causes of things and, again, by definition, science cannot tell you about them"
Who made these "definitions"? No one in sight.
"This is how you get the phenomenon of philistines like Richard Dawkins"
Oh I see, Dawkins, a great evolutionary biologist, is a philistine. The evidence? I guess because the author disagrees with Dawkins about God. No argument is given.
