Gentlemen,

The subject of the present Lecture will be—The revival of Atheism. And I do not employ the word 'atheism'—a term which has been so greatly abused—without mature reflection. When Socrates opposed the idea of the holy God to the impure idols of paganism; when he dethroned Jupiter and his train in order to celebrate "the supreme God, who made and who guides the world, who maintains the works of creation in the flower of youth, and in a vigor always new,"[40] they accused Socrates of being an atheist. Descartes, the great geometrician who proclaimed the existence of God more certain than any theorem of geometry, has been denounced as an atheist. When men began to forsake the temples of idols in order to worship the unknown God who had just manifested Himself to the world, the Christians were accused of atheism because they refused to bow down to wood and stone. Such abuses might dispose one to renounce the use of the word. Besides, when a word has been for a long time the signal of persecution and the forerunner of death, one hesitates to employ it. In an age when atheists were burned, generous minds would use their best efforts to prove that men suspected of atheism had not denied God, because they would not have been understood had they attempted to say—"They have denied God perhaps, but that is no reason for killing them." Thence arose the sophistical apologies for certain doctrines, apologies made with a good intention, but which trouble the sincerity of history. These are the brands of servitude, which must disappear where liberty prevails. We are able now to call things by their proper names, for there exist no longer for atheism either stakes or prisons. In affirming that certain writers, some of whom are just now the favorites of fame, are shaking the foundations of all religion, one exposes no one to severities which have disappeared from our manners, one only exposes oneself to the being taxed with intolerance and fanaticism. But candor is here a duty. If this duty were not fulfilled, liberty of thought would no longer be anything else than liberty of negation; and, while truth was oppressed, error alone would be set free.

Let us settle clearly the terms of this discussion. It is often asserted that an atheist does not exist. Does this mean that the lips which deny God, always in some way contradict themselves? Does it mean that every soul bears witness to God, perhaps unconsciously to itself, either by a secret hope, or by a secret dread? This is true, as I think; but we are speaking here of doctrines and not of men. It is true again that the negation of the Creator allows of the existence, in certain philosophies, of generous ideas and elevated conceptions. Such men, while they put God out of existence, desire to keep the true, the beautiful, the good; they hope to preserve the rays, while they extinguish the luminous centre from which they proceed. Such systems always tend to produce the deadly fruits pointed out in my last lecture; but men devoted to the severe labors of the intellect often escape, by a noble inconsistency, the natural results of their theories. Therefore, in the inquiry on which we are about to enter, the term 'atheism' implies, with regard to persons, neither reproach nor contempt. It simply indicates a doctrine, the doctrine which denies God. This denial takes place in two ways: It is affirmed that nature, that is to say matter, force devoid of intelligence and of will, is the sole origin of things; or, the reality is acknowledged of those marks which raise mind above nature, but it is affirmed that humanity is the highest point of the universe, and that above it there is nothing. Such are the two forms of atheism.

Perhaps you expect here the explanation of a doctrine which is often described as holding a sort of middle place between the negation and the affirmation of God, namely, pantheism. Pantheism, in the true sense of that word, is a system according to which God is all, and the universe nothing. This extraordinary thesis is met with in India. A Greek, Parmenides, has vigorously sustained it. We have in it a kind of sublime infatuation. In presence of the one and eternal Being thought collapses in bewilderment; and thenceforward it experiences for all that is manifold and transitory a disdain which passes into negation. In the domain of experience, all is limited, temporary, imperfect; and reason seeks the perfect, the eternal, the infinite. The doctrine of creation alone explains how the universe subsists in presence of its first cause. In ignorance of this doctrine, some bold thinkers have cut the knot which they could not untie. They have declared that reason alone is right, and that experience is wrong: the world does not exist, it is but an illusion of the mind. Whence proceeds this illusion? If perfection alone exists, how comes that imperfect mind to exist which deceives itself in believing in the reality of the world? To this question the system has no answer. Such is true pantheism; but it is not to dangers so noble that most minds run the risk of succumbing. What is commonly understood by pantheism is the deification of the universe. The idea of God is not directly denied, but it undergoes a transformation which destroys it. God is no longer the eternal and Almighty Spirit, the Creator; but the unconscious principle, the substance of things, the whole. The universe alone exists; above it there is nothing; but the universe is infinite, eternal, divine. The higher wants of the reason, mingling with the data derived from experience, form an imposing and confused image, which, while it beguiles the imagination, perverts the understanding, deceives the heart, and places the conscience in peril. In a philosophical point of view, it is a contradiction of thought, which seeks the Infinite Being, and, being unable to discover Him, gives the character of infinity to realities bounded by experience. In a religious point of view, it is an aberration of the heart, which preserves the sentiment of adoration, but perverts it by dispersing it over the universe. "Pantheism," says M. Jules Simon, "is only the learned form of atheism; the universe deified is a universe without God."[41] From the moment that the reason endeavors to see distinctly, pantheism vanishes like a deceitful glare. Atheism disengages itself from the cloak which was concealing its true nature, and the mind remains in presence of nature only, or of humanity only. We will proceed to take a rapid glance at some few of the countries of Europe, in order to discover and point out in them the traces of this melancholy doctrine. Let us begin with France.

In the year 1844, just twenty years ago, some French writers, representing the philosophy, in some measure official, of the time, united to publish a Dictionnaire des sciences philosophiques. M. Franck, the director of this useful and laborious enterprise, said in the preface to the work: "Atheism has well nigh completely disappeared from philosophy; the progress of a sound psychology will render its return for ever impossible." In speaking thus, he expressed the thoughts and hopes of the school of which he remains one of the most estimable representatives. A generous impulse was animating a group of intelligent and learned young men. Their hope was to translate Christianity into a purely rational doctrine, to purify religious notions without destroying them, and, while endowing humanity with a vigorous scientific culture, to leave to it its lofty hopes. The object in view was to establish a philosophy founded upon a serious faith in God; and to this philosophy was promised the progressive and pacific conquest of the human race.[42] Twenty years have passed, and things bear quite another aspect. To language expressive of security have succeeded the accents of anxiety and words of alarm. The cause which was proclaimed victorious is defended at this day like a besieged city. You will remark however,—that I may not leave you beyond measure discouraged by the facts of which I have to tell you,—you will remark, I say, that it is the efforts attempted in the cause of good which have helped to set me on the track of evil; it has often been the defence which has fixed my attention upon the attack.

The materialism of the last century seems to have maintained a strong hold upon one part of the Paris school of medicine. We do find in France a good many physicians who, like Boerhave, render homage to religion, and a good many physiologists who, like the great Haller, are ready to defend beliefs of the spiritual order;[43] but, among men specially devoted to the study of matter, many succumb to the temptation of refusing to recognize anything as real which does not come under the experience of the senses. This however is not one of the points which offer themselves most strikingly for our examination. The atheistic manifestations of the socialist schools have more novelty, and perhaps more importance.

Man is naturally a social being. Good and evil have their primitive seat in the heart of individuals, but good and evil are transferred into institutions of which the influence is morally beneficial or pernicious. If socialism consists in recognizing the importance of social institutions, in cherishing ideas of progress and hopes of reform, I trust that we are all socialists. Do we desire progress by the ever wider diffusion of justice and love? From the moment that, across the conscience whereon divine rays are falling, we have descried the eternal centre of light, we understand that God is the most implacable enemy of abuses. How is it then that atheism sometimes manifests itself in attempts at social reform? We may explain it, without so much as pointing out the influence, but too real, of the faults committed by the representatives of religion. Faith is a principle of action; it is, as history testifies, the grand source of the progress of human society; but faith is also a principle of patience. The brow of every believer is more or less illumined by the rays of His peace who is patient because He is eternal. Eager to effect good to the utmost extent of his ability, he accomplishes his work with that calm activity to which are reserved durable victories. In the impossible (for if the word impossible is not French, it is human) the believer recognizes one of the manifestations of the supreme Will, and immortal hope enables him to support the evils which he does not succeed in destroying. But this is not enough for impatient reformers. Ignorant of the profound sources of evil, they think that institutions can do everything, and that a change of laws would suffice to reform men's hearts; they believe that the organization of society alone hinders the realization of good and of happiness. The resignation of believers appears to them a stupid lethargy, and in their patient expectation of a judgment to come they see only an obstacle to the immediate triumph of justice on the earth. What if the nations were persuaded that there is nothing to be looked for beyond the present life, so that all that is to be done is to make to ourselves a paradise as soon as may be here below! If they were persuaded that all appeal to the Judge in heaven is a chimerical hope, with what ardor would they throw themselves into schemes of revolution! Thus it is that certain political innovators are led to seek in the negation of God one of their means of action.

Two views, therefore, essentially diverse, govern the labors of the renovators of society. The one class desire to realize, in an ever larger measure, justice and love; religious convictions are the strongest support of their work. The other class would uproot from men's minds every principle of faith, in order the more readily to obtain the realization of their theories. These two classes of men seem at times to be fighting all together in the mêlée of opinions. They meet, as, in the doubtful glimmer of the dawn, might meet together laborious workmen who are anticipating the daylight, and evil-doers who are fleeing from the sun.

In order to form a just estimate of the labors of the socialist schools, it would be necessary to make a bold and straightforward inquiry into the object of their studies, and to discern, in the midst of mad-brained and guilty dreams, whatever flashes of light might disclose some prophetic vision of the future. This is no task of ours. It is enough for us to remark that in France, as also in the other countries of Europe, the negation of God discovers itself in this order of ideas. It discovers itself at one time by an idolatry of humanity, at another by a materialistic enthusiasm for corporeal indulgences. Disregarding the sensual imaginations which disgrace the works of Fourrier, let us turn our attention elsewhere.

M. Vacherot, a sober philosopher, of high intellectual power and elevated sentiment, has lately published, unhappily, twelve hundred pages destined to maintain the thesis that God does not exist.[44] Man conceives the idea of perfection, and not finding that perfection realized either in the world or in himself, he rises to the conception of a real and perfect being: such is the usual process of metaphysical reasoning. For M. Vacherot, reality and perfection mutually exclude one another; this is one of his fundamental theses. This thesis does but interpret the result of our experience, by refusing us the right to raise ourselves higher. The world with which we are acquainted is imperfect; therefore—say Plato, Saint Augustine, and Descartes—the perfection of which we have the idea is realized in a Being superior to the world. The world with which we are acquainted is imperfect, therefore there is a contradiction between the ideal and the real, says M. Vacherot, who makes thus of the general result of experience the absolute rule of truth. To say therefore of God that He is perfect, is to affirm that He does not exist, inasmuch as the ideal is never realized. Thought thus finds itself placed in a situation at once odd and violent. If God is perfect, He does not exist. If God exists, He is not perfect. The respect which we owe to the Being of beings forbids us to believe in Him; to affirm His existence would be to do outrage to His perfection. The author of this theory renders a worship to that ideal which does not exist, and towards which he affirms nevertheless that the world is gravitating by the law of progress. This worship is of too abstract a nature to secure many adherents; it can only become popular by taking another shape, and it does so in this way: We conceive of that perfection which in itself does not exist; it exists therefore in our thought. Since the world, by the law of progress, is tending towards perfection, the world has for its end and law a thought of the human mind. The human mind therefore is the summit of the universe, and it is it that we must adore. We are here out of the region of pure abstraction, and arrive at the doctrines of the Positivist school.
