I think that intelligentsias advanced proficiency with words tilts the balance between the words and action. The words are extremely important in human life, but not self-sufficient without action. Operating exclusively in the realm of word constructs skews their worldview from the real-world to fantasy-world, from how it is to how it should be in the ideal world.
Looks like this tendency is common among all liberal arts professions such as journalism, arts, acting, social studies, etc., not just the university professors. Common sense that represents the action side of human life gets neglected in favor of wishful thinking.
It is interesting that such thinkers (very popular at FR) as Victor Davis Hanson, Lee Harris, Mark Steyn often emphasized this trait of Islamism: living in the fantasy world of their ideology instead of the hard earned reality, and supporting their fantasy ideology with oil money gifted by mother nature and developed by the hated West, instead of supporting their grandeur wishes with the hard labor of their own. At the same time the Left demands no less than Utopia level perfection from ourselves: when quick and unbelievably successful two wars in a short time are still quagmire to them, when nothing short of the proof beyond a reasonable doubt is acceptable to them as proof of guilt of the enemies who build in deniability into their actions to begin with.
This maybe explains the Lefts opposition to Americas bringing a muscular reality check to the sick Mideast, their strange affinity to people who would be their mortal enemies if the Left did not loose common sense. If left alone the Left would quickly disarm us and leave totally defenseless against any enemy.
It seems that we are at the same time in conflict with our own fantasy Utopists on the Left, here and in Europe and fantasy Islamists across the sea. And as conservatives we want to conserve our reality for our kids.
You can also see why this distinction is important, for example, in some of the "realism" of the right--, in Fukuyama's immanent marxian conservativism.
