The linked is well worth the read, there is no need to understand the relationship of the classical personnages referenced to get the point.
In its crassest but perhaps also most powerful form, this desire led to that familiar phenomenon Benda dubbed “the cult of success.” It is summed up, he writes, in “the teaching that says that when a will is successful that fact alone gives it a moral value, whereas the will which fails is for that reason alone deserving of contempt.” In itself, this idea is hardly novel, as history from the Greek sophists on down reminds us. In Plato’s Gorgias, for instance, the sophist Callicles expresses his contempt for Socrates’ devotion to philosophy: “I feel toward philosophers very much as I do toward those who lisp and play the child.” Callicles taunts Socrates with the idea that “the more powerful, the better, and the stronger” are simply different words for the same thing. Successfully pursued, he insists, “luxury and intemperance … are virtue and happiness, and all the rest is tinsel.” How contemporary Callicles sounds!
Or to put it simply, "might is right!".
To succinctly explain "why the the title"?
This is not simply to say that there are many anti-intellectual elements in society: that has always been the case. “Non-thought,” in Finkielkraut’s phrase, has always co-existed with the life of the mind. The innovation of contemporary culture is to have obliterated the distinction between the two. “It is,” he writes, “the first time in European history that non-thought has donned the same label and enjoyed the same status as thought itself, and the first time that those who, in the name of ‘high culture,’ dare to call this non-thought by its name, are dismissed as racists and reactionaries.” The attack is perpetrated not from outside, by uncomprehending barbarians, but chiefly from inside, by a new class of barbarians, the self-made barbarians of the intelligentsia. This is the undoing of thought. This is the new “treason of the intellectuals.”
Again, well worth reading the linked ... it gets a little esoteric in spots, but the key points are easy to pick out.
