The general order of things that takes care of fleas and moles, also takes care of men

From Montaigne's Essays, Chapter 37 Of the Resemblance of Children to Their Fathers.

Let it alone a little; the general order of things that takes care of fleas and moles, also takes care of men, if they will have the same patience that fleas and moles have, to leave it to itself. 'Tis to much purpose we cry out "Bihore,"—[A term used by the Languedoc waggoners to hasten their horses]—'tis a way to make us hoarse, but not to hasten the matter. 'Tis a proud and uncompassionate order: our fears, our despair displease and stop it from, instead of inviting it to, our relief; it owes its course to the disease, as well as to health; and will not suffer itself to be corrupted in favour of the one to the prejudice of the other's right, for it would then fall into disorder. Let us, in God's name, follow it; it leads those that follow, and those who will not follow, it drags along, both their fury and physic together. Order a purge for your brain, it will there be much better employed than upon your stomach.
