I don't know if the source is dogmatism on your part, but I do know you're really not thinking about/listening to what I'm saying.
You can tell from what I said that I didn't just skim for a quote. That's you skimming my answer and looking for something to attack. Do you see it, on a second reading?
In fact--though this was less apparent from what I wrote--I read the entire Wikipedia article looking for an indication that I should invest the time to explore the 1800 pages of The Matter with Things. The Master and His Emissary seems possibly interesting. However, when faced with multiple critiques that McGilchrist fails to engage sufficiently deeply with epistemological philosophy (Wikipedia also quotes Louth with the same complaint), when you're sending me there to learn epistemology, my answer is: probably not worth it. And Ellis said it well, so why not quote? (I have thought similar things, though not phrased it as quotably, about the Frankfurt School philosophers: I admire their attempt, but their ideas ended up actually dangerous largely because of an attitude that in effect, but possibly inadvertently, rejects the epistemic view needed to support the scientific method.)
