Contentment with life cannot be reduced or found only in the practice of having the right thought.
Adorno and Horkheimer noted that today’s anti-intellectualism can in part stem from resentment of perceived happiness that the intellectual appears to have achieved mentally. This appearance of happiness, which isn’t true, raises such ire because it is a reminder of the question of the crisis of society, a reminder of an unfree society, which one even unknowlingly participates in its reproduction.
And speaking of that reproduction, even thought participates in labor that is the total mediation of society. There are those who can trace the movement of Spirit to trace its trajectory, to see how the crumbling totality is sick, but—as Nietzsche points out—its sickness is pregnancy, and it is pregnant with a classless society. The problem is that such an outcome requires the overcoming of this sickness. Either that or barbarism. Perhaps the intellectual is discontent because of a more acute sense of the latter.
