Intellectualism is, by and large, competitive. The flaw becomes immediately apparent. If we presume Truth to be the goal, admittedly something of a leap in many circles, we must then surely acknowledge that the pursuit thereof through rhetorical means disadvantages those who cannot perform rhetorically. Having done so, we have created artificial selection in which it is not the best ideas which rise to the top, but rather the ideas espoused by the most eloquent speakers.
Plato spoke on the subject at length; I'm hardly unique. Yet we still seem to be making the same mistake, so perhaps my glib address to it remains necessary, if self-indulgent.
