Joseph de Maistre never met men in the abstract. Frenchmen, Italians, yes—but not “Man.” There were no universal principles of government, applicable to all men at all times, only governments suited to the different kinds of people in different countries.
Maistre was right, and to that extent, American conservatives are wrong if they think that their constitution is the perfection of human reason, a light unto the Gentiles. They’re especially wrong since the Constitution isn’t looking too good these days. One can love liberty and one can love America’s Constitution, but one can’t love both together without a thick set of blinders.
