Life has many good things. The problem is that most of these good things can be gotten only by sacrificing other good things. We all recognize this in our daily lives. It is only in politics that this simple, common sense fact is routinely ignored.
It may be expecting too much to expect most intellectuals to have common sense, when their whole life is based on their being uncommon -- that is, saying things that are different from what everyone else is saying. There is only so much genuine originality in anyone. After that, being uncommon means indulging in pointless eccentricities or clever attempts to mock or shock.
The charge is often made against the intelligentsia and other members of the anointed that their theories and the policies based on them lack common sense. But the very commonness of common sense makes it unlikely to have any appeal to the anointed. How can they be wiser and nobler than everyone else while agreeing with everyone else?
