  Letter to the General  Assembly of the Church of Scotland, 3  Aug.

Le bon sens est la chose du monde la mieux partage¤  e: car chacun pense en e"  tre si bien pourvu, que ceux me"  me qui sont les plus difficiles a'   contenter en toute autre chose n'ont point coutume d'en de¤  sirer plus qu'ils ont. En quoi il n'est pas vraisemblable que tous se trompent; mais pluto" t  cela te¤  moigne que la puissance de bien juger et distinguer le vrai d'avec le faux, qui est proprement ce qu'on nomme le bon sens ou la raison, est naturellement e¤  gale en tous les hommes. Good sense is the most fairly distributed thing in the world; for everyone thinks himself so well supplied with it, that even those who are hardest to satisfy in every other way do not usually desire more of it than they already have. In this matter it is not likely that everybody is mistaken; it rather goes to show that the power of judging well and distinguishing truth from falsehood, which is what we properly mean by good sense or reason, is naturally equal in all men.
