When ancient opinions and rules of life are taken away, the loss cannot possibly be estimated. From that moment we have no compass to govern us; nor can we know distinctly to what port we steer. Europe, undoubtedly, taken in a mass, was in a flourishing condition the day on which your revolution was completed. How much of that prosperous state was owing to the spirit of our old manners and opinions is not easy to say; but as such causes cannot be indifferent in their operation, we must presume that on the whole their operation was beneficial. We are but too apt to consider things in the state in which we find them, without sufficiently adverting to the causes by which they have been produced and possibly may be upheld. Nothing is more certain than that our manners, our civilization, and all the good things which are connected with manners and with civilization have, in this European world of ours, depended for ages upon two principles and were, indeed, the result of both combined: I mean the spirit of a gentleman and the spirit of religion. The nobility and the clergy, the one by profession, the other by patronage, kept learning in existence, even in the midst of arms and confusions, and whilst governments were rather in their causes than formed. Learning paid back what it received to nobility and to priesthood, and paid it with usury, by enlarging their ideas and by furnishing their minds. Happy if they had all continued to know their indissoluble union and their proper place! Happy if learning, not debauched by ambition, had been satisfied to continue the instructor, and not aspired to be the master! Along with its natural protectors and guardians, learning will be cast into the mire and trodden down under the hoofs of a swinish multitude.
