Racism is an obvious manifestation of the anti-conceptual mentality. So is
xenophobia—the fear or hatred of foreigners (“outsiders”). So is any caste
system, which prescribes a man’s status (i.e., assigns him
to a tribe) according to his birth; a caste system is perpetuated by a special
kind of snobbishness (i.e., group loyalty) not merely among the aristocrats,
but, perhaps more fiercely, among the commoners or even the serfs, who like to
“know their place” and to guard it jealously against the outsiders from above
or from below. So is guild socialism. So is any kind of ancestor worship or of
family “solidarity” (the family including uncles, aunts and third cousins). So
is any criminal gang.
Tribalism . . . is the best name to give to all the group manifestations of the
anti-conceptual mentality.
