In Plato's Theaetetus, the ancient Greek philosopher Socrates spoke derisively about people who are “eu a-mousoi,” an ancient Greek term that literally means “happily without muses.” These are the plodding materialists who have no hunger for divine inspiration and no need of higher insights about reality. They mistakenly believe that in order to be real, a thing must be perceivable by the five senses. They aren't trustworthy.
“Socrates argues that the invisible world is the most intelligible and that the visible world is the least knowable, and the most obscure.” - Wikipedia
One of the worst consequences of religious fundamentalism, in my opinion, has been to give justification to the rise of militant cults of plodding materialists who are eu a-mousoi.
