Two nice quotes (HT Jacob Levy) on pluralism

Reading through Jacob Levy's (great) new book, Rationalism, Pluralism, and Freedom, I came across (p. 66) these two quotes:

There are certain ideas of uniformity, which sometimes strike great geniuses (for they even affected Charlemagne), but infallibly make an impression on little souls. They discover therein a kind of perfection, which they recognize because it is impossible for them not to see it; the same authorized weights, the same measures in trade, the same laws in the state, the same religion in all its parts. But is this always right and without exception? Is the evil of changing constantly less than that of suffering? And does not a greatness of genius consist rather in distinguishing between those cases in which uniformity is requisite, and those in which there is a necessity for differences? In China the Chinese are governed by the Chinese ceremonial and the Tartars by theirs; and yet there is no nation in the world that aims so much at tranquillity. If the people observe the laws, what signifies it whether these laws are the same?  Montesquieu, The Spirit of the Laws.

And this:

The man of system, on the contrary, is apt to be very wise in his own conceit; and is often so enamoured with the supposed beauty of his own ideal plan of government, that he cannot suffer the smallest deviation from any part of it. He goes on to establish it completely and in all its parts, without any regard either to the great interests, or to the strong prejudices which may oppose it. He seems to imagine that he can arrange the different members of a great society with as much ease as the hand arranges the different pieces upon a chess-board. He does not consider that the pieces upon the chess-board have no other principle of motion besides that which the hand impresses upon them; but that, in the great chess-board of human society, every single piece has a principle of motion of its own, altogether different from that which the legislature might chuse to impress upon it.   Adam Smith, Theory of Moral Sentiments.

I'd encountered (as have most MOJ readers, I imagine) these passages before, but . . . they seemed timely.
