Nevertheless, if his work was given to the public only in a curtailed and mutilated form, his object remained. The Études de la Nature was destined to paraphrase the first part of Fénélon's Traité de l'existence de Dieu, especially of the second chapter, entitled "Proofs of the Existence of God, taken from the Consideration of the Chief Marvels of Nature." Bernardin de Saint-Pierre was born religious at heart in an age which had "lost the taste for God," to use Bossuet's expression, when believers themselves were wanting in spirit and tenderness. He was brought up upon the celebrated phrase of Voltaire—"The people must have a religion"—and never could reconcile himself to hear repeated around him that in truth, "Religion is the portion of the people, just a kind of political engine invented to keep them in check" (Études). Atheism seemed to him a diminution of our being, a lessening of its most noble sensations and its most elevated emotions. "It is only religion," he said, "which gives to our passions a lofty character"; and he related, apropos of this, that the day on which he himself had perceived most vividly the power of the "divine majesty" of suffering was in contemplating a peasant woman from Caux prostrated at the foot of the cross one stormy day, praying, with clasped hands, her eyes cast up to heaven, for a boat which was in danger. The seventeenth century would not have admitted for poetical reasons that they believed thus in God. Men's minds were then too serious; and the great spiritual directors of the time of Bossuet and Bourdaloue, without mentioning the Jansenists, would have been shocked at the sentimental religion of Bernardin de Saint-Pierre. But the eighteenth century had taught men to be less nice, and such things appeared to it to be sublime.

It must be said that they were very tired of arguments and philosophy, and the idea that they might seek for truth by some less tiresome paths was very pleasing. They had for so long lived like the Carthusian friars of the Harmonies. "One day one of my friends went to visit a Carthusian friar. It was the month of May; the garden of the recluse was covered with flowers, in the borders and on the fruit-trees. As for him, he had shut himself up in his room, from which he could see absolutely nothing. 'Why,' asked my friend, 'have you closed your shutters?' 'In order,' replied the friar, 'to be able to meditate without distraction on the attributes of God.' 'Ah!' said my friend, 'don't you think that perhaps you may find greater distraction in your own heart than nature would give to you in the month of May? Take my advice, open your shutters and shut the door upon your imagination.'"

Open your shutters and shut your books, cried this new-comer in the world of letters. Nature is the source of everything which is ingenious, useful, pleasant and beautiful, but she must be contemplated in all simplicity of heart. It is for our happiness that she hides from us the laws which govern her mighty forces, and there is a kind of thoughtless impiety in wishing to penetrate too deeply into her mysteries. Besides, we always fail, and our imprudent efforts only succeed in adding the mist of our errors to the cloud which veils her divinity. Let us make up our minds to not being taken into the Divine confidence; content to examine Nature at work, observing her work without studying it on a system, forgetting what the scholars and the academies have decided and decreed as a matter of doctrine. The forces of Nature, ever young and active, form one of the most wonderful and admirable spectacles which the universe affords us. The same spirit of life which formed our world out of chaos, continues to develop the germs under our eyes, to repair the wounded plants and renew their injured tissues with fresh growths. They tell you that Nature brings forth at hazard, producing pell-mell and indifferently the good and the bad, annulling the good by this disorder. But I tell you that not a blade of grass has been made at hazard, and that the least mite testifies to the existence of a sovereign intelligence and goodness. I assure you also that this goodness has only had one pre-occupation—yourself; but one aim—your happiness. God made nature for man, and man for Himself. Man is the end and aim of everything upon the earth, and the proofs of this are infinite in number.

A great part of the Études is taken up with the gathering together of these proofs. I do not believe that there exists another so intrepid a partisan of final causes. Nothing turns him from his demonstration, not facts, nor absurdities, nor ridicule. Things are so because it is necessary to the happiness of man that they should be so: nothing turns Bernardin de Saint-Pierre from that opinion. I do not say that he scoffed at science; he looked upon himself as a scientific spirit who was to set his predecessors right, including Descartes and Newton; I only say that he speaks about it rather as though he were laughing at it.

Our earth, then, has been solidified, modelled and carved out by God for our needs and our comfort. There is not a mountain whose height, breadth, and site have not been calculated by Divine wisdom for our advantage. One is intended to refresh us with its ice, another to protect us from the north wind, a third to produce a healthful current of air; this last we call eolian. Those islands of rock strewn along the seashore, and vulgarly called sand-banks, are fortifications placed there by Providence, without which our coasts would be demolished by the ocean. Those which one remarks at the mouths of water-courses "form channels for the rivers, each channel taking a different direction, so that if one becomes stopped up by the winds or the currents from the sea, the water can escape by another." It speaks for itself that God does not have to try a thing over and over again before it is perfect. Creation was perfect from the first day, and Bernardin de Saint-Pierre suppresses the slow evolutions, due to the action of the forces of nature, which according to some incessantly alter the surface of the earth. That surface is unchangeable. There is no example that the sea ever "hollowed out a bay, or detached anything from the continent;" that the "rivers formed at their entrance into the sea sand-banks and promontories;" that ancient ports had been effaced, islands destroyed, or mountains denuded and levelled to the ground. In truth, the works of God, like those of man, are subject to wear, and need reparation; but the Divine Architect is never idle, and works without ceasing to maintain them, which amounts to the same thing.

The means which He employs for reparation often escape our notice from their very simplicity. What pedestrian has not execrated the clouds of sand or dust which the wind raises on the strand or on barren plains. He would have been rather astonished if he had known that he was witnessing the dispersal of materials designed by Providence to replace the soil in the mountains, which had been worn away by water. Sand and dust are transported to the tops of the peaks upon the wings of storms, thanks to the "fossil attractions" of the mountains.

It was six years after Buffon's Époques de la Nature had appeared, that Bernardin de Saint-Pierre offered to the public this astonishing system of the Universe. It needed a certain amount of courage to be so deliberately behindhand.

The theory of final causes thus carried to extremes occasioned a good deal of embarrassment to the Deist. It is no slight matter to undertake to explain, to the advantage of Providence, everything that there is upon the earth without any exception; so many things appear useless, so many hurtful. Saint-Pierre never despaired of finding justification for every one of them, with human happiness as its basis. He went on bravely without disturbing himself that the laugh was at his expense, and with an ardour of conviction which convinced many of the men and almost all the women who read him. The spirit of that day was not very scientific.

Of what use are volcanoes? Hardly any one has failed to perceive that rivers are, so to speak, the drains of the continent. The oils, the resin, and the nitre of vegetables and animals are carried by the water-courses to the sea, where all their component parts become dissolved, covering the surface with fatty matter, which does not evaporate because it resists the action of the air. Without the intervention of Providence the entire ocean since the existence of the world would be defiled with these tainted oils; but Providence made volcanoes, and the waters were purified. In fact, volcanoes "do not proceed from heat inside the earth, but they owe their origin to the waters, and the matter contained in them. One can convince one's self of this fact by remarking that there is not a single volcano in the interior of a continent, unless it is in the neighbourhood of some great lake like that of Mexico." Nature, obeying a Divine impulse, has "lighted these vast furnaces on the shores of the ocean," so that the oils of which we have spoken, being attracted towards them by a phenomenon which the author does not explain, are burnt up as the weeds in a garden are burnt in the autumn by a careful gardener. One does in truth find lava in the interior of a country, but a proof that it owes its origin to water is that the volcanoes which have produced it have become extinct, when the waters have failed. Those volcanoes were lighted there like those of our day, by the animal and vegetable fermentations with which the earth was covered after the Deluge, when the remains of so many forests and so many animals, whose trunks and bones are still found in our quarries, floated on the surface of the ocean, forming huge deposits, which the currents accumulated in the cavities of the mountains, so that the ancient craters of the Auvergne mountains prove that all volcanoes are found beside the sea. Inundations afford us the pleasures of boating and fishing. That is the reason that the nations which inhabit the shores of the Amazon and the Orinico, and many other rivers which overflow their banks, looked upon these inundations as blessings from heaven before the arrival of Europeans, who upset their ideas: "Was it, then, so displeasing a spectacle for them to see their immense forests intersected by long water-roads, which they could navigate without trouble of any sort in their canoes, and of which they could gather in the produce with the greatest ease? Some colonies like those on the Orinico, convinced of these advantages, had adopted the strange habit of living in the tops of trees, like the birds, seeking board, lodging and shelter under their foliage. In spite of the epithet strange, one feels that he regretted these picturesque manners, and that it would not have displeased him at all to see the dwellers on the banks of the Loire, nesting with the magpies and jays in their own poplars."

Beasts of prey rid the earth of dead bodies, which without them would not fail to infect the air. Every year there dies a natural death at least the twentieth part of the quadrupeds, the tenth part of the birds, and an infinite number of insects, of which most of the species only live a year. There are some insects even who only live a few hours, such as the ephemera. This enormous destruction would soon poison the air and the water without the aid of the innumerable army of grave-diggers created and maintained by Nature to keep the surface of the globe clean. Saint-Pierre draws a description of it which is wonderful for its colour and spirit: "It is above all in hot countries, where the effects of decomposition are most rapid and most dangerous, that Nature has multiplied carnivorous animals. Tribes of lions, tigers, leopards, panthers, civet-cats, lynxes, jackals, hyenas, condors, &c., there come to reinforce the wolves, foxes, martens, otters, vultures, ravens, &c. Legions of voracious crabs make their homes in the sand there; alligators and crocodiles lie in ambush amongst their reeds, an innumerable species of shell-fish, armed with implements to enable them to suck, to bore, to file, to crush, bristle on the rocks and pave their sea-shores. Clouds of sea-birds fly screaming along the rocks, or sail round them on the tops of the waves seeking their prey; eels, garfish, shad, and every species of cartiaginous fish which only lives upon flesh, such as long sharks, big skate, hammer-fish, octopuses armed with suckers, and every variety of dog-fish, swim about in shoals, occupied all the time in devouring the remains of the dead bodies which collect there. Nature also musters insects to hasten on the destruction. Wasps armed with shears cut the flesh, flies pump out the fluids, marine worms separate the bones.... What remains of all these bodies, after having served as food to numberless shoals of other kinds of fish, some with snouts formed like a spoon, others like a pipe, so that they can pick up every crumb from the vast table, at last converted by so many digestions into oils and fats and added to the vegetable pulps which descends from all parts into the ocean, would reproduce a new chaos of putrefaction in its waters, if the currents did not carry it to the volcanoes, the fires of which succeed in decomposing it and giving it back to the elements. It is for this reason, as we have already indicated, that volcanoes ... are all in the neighbourhood of the sea or big lakes."
