The Necessity of Atheism

[NOTE -- The Necessity of Atheism was published by Shelley in 1811. In 1813 he printed a revised and expanded version of it as one of the notes to his poem Queen Mab. The revised and expanded version is the one here reprinted.]

There Is No God

This negation must be understood solely to affect a creative Deity. The hypothesis of a pervading Spirit co-eternal with the universe remains unshaken.

A close examination of the validity of the proofs adduced to support any proposition is the only secure way of attaining truth, on the advantages of which it is unnecessary to descant: our knowledge of the existence, of a Deity is a subject of such importance that it cannot be too minutely investigated; in consequence of this conviction we proceed briefly and impartially to examine the proofs which have been adduced. It is necessary first to consider the nature of belief.

When a proposition is offered to the mind, It perceives the agreement or disagreement of the ideas of which it is composed. A perception of their agreement is termed belief. Many obstacles frequently prevent this perception from being immediate; these the mind attempts to remove in order that the perception may be distinct. The mind is active in the investigation in order to perfect the state of perception of the relation which the component ideas of the proposition bear to each, which is passive; the investigation being confused with the perception has induced many falsely to imagine that the mind is active in belief. -- that belief is an act of volition, -- in consequence of which it may be regulated by the mind. Pursuing, continuing this mistake, they have attached a degree of criminality to disbelief; of which, in its nature, it is incapable: it is equally incapable of merit.

Belief, then, is a passion, the strength of which, like every other passion, is in precise proportion to the degrees of excitement.

The degrees of excitement are three.

The senses are the sources of all knowledge to the mind; consequently their evidence claims the strongest assent.

The decision of the mind, founded upon our own experience, derived from these sources, claims the next degree.

The experience of others, which addresses itself to the former one, occupies the lowest degree.

(A graduated scale, on which should be marked the capabilities of propositions to approach to the test of the senses, would be a just barometer of the belief which ought to be attached to them.)

Consequently no testimony can be admitted which is contrary to reason; reason is founded on the evidence of our senses.

Every proof may be referred to one of these three divisions: it is to be considered what arguments we receive from each of them, which should convince us of the existence of a Deity.

1st, The evidence of the senses. If the Deity should appear to us, if he should convince our senses of his existence, this revelation would necessarily command belief. Those to whom the Deity has thus appeared have the strongest possible conviction of his existence. But the God of Theologians is incapable of local visibility.

2d, Reason. It is urged that man knows that whatever is must either have had a beginning, or have existed from all eternity, he also knows that whatever is not eternal must have had a cause. When this reasoning is applied to the universe, it is necessary to prove that it was created: until that is clearly demonstrated we may reasonably suppose that it has endured from all eternity. We must prove design before we can infer a designer. The only idea which we can form of causation is derivable from the constant conjunction of objects, and the consequent inference of one from the other. In a base where two propositions are diametrically opposite, the mind believes that which is least incomprehensible; -- it is easier to suppose that the universe has existed from all eternity than to conceive a being beyond its limits capable of creating it: if the mind sinks beneath the weight of one, is it an alleviation to increase the intolerability of the burthen?

The other argument, which is founded on a Man's knowledge of his own existence, stands thus. A man knows not only that he now is, but that once he was not; consequently there must have been a cause. But our idea of causation is alone derivable from the constant conjunction of objects and the consequent Inference of one from the other; and, reasoning experimentally, we can only infer from effects caused adequate to those effects. But there certainly is a generative power which is effected by certain instruments: we cannot prove that it is inherent in these instruments" nor is the contrary hypothesis capable of demonstration: we admit that the generative power is incomprehensible; but to suppose that the same effect is produced by an eternal, omniscient, omnipotent being leaves the cause in the same obscurity, but renders it more incomprehensible.

3d, Testimony. It is required that testimony should not be contrary to reason. The testimony that the Deity convinces the senses of men of his existence can only be admitted by us, if our mind considers it less probable, that these men should have been deceived than that the Deity should have appeared to them. Our reason can never admit the testimony of men, who not only declare that they were eye-witnesses of miracles, but that the Deity was irrational; for he commanded that he should be believed, he proposed the highest rewards for, faith, eternal punishments for disbelief. We can only command voluntary actions; belief is not an act of volition; the mind is ever passive, or involuntarily active; from this it is evident that we have no sufficient testimony, or rather that testimony is insufficient to prove the being of a God. It has been before shown that it cannot be deduced from reason. They alone, then, who have been convinced by the evidence of the senses can believe it.

Hence it is evident that, having no proofs from either of the three sources of conviction, the mind cannot believe the existence of a creative God: it is also evident that, as belief is a passion of the mind, no degree of criminality is attachable to disbelief; and that they only are reprehensible who neglect to remove the false medium through which their mind views any subject of discussion. Every reflecting mind must acknowledge that there is no proof of the existence of a Deity.

God is an hypothesis, and, as such, stands in need of proof: the onus probandi rests on the theist. Sir Isaac Newton says: Hypotheses non fingo, quicquid enim ex phaenomenis non deducitur hypothesis, vocanda est, et hypothesis vel metaphysicae, vel physicae, vel qualitatum occultarum, seu mechanicae, in philosophia locum non habent. To all proofs of the existence of a creative God apply this valuable rule. We see a variety of bodies possessing a variety of powers: we merely know their effects; we are in a estate of ignorance with respect to their essences and causes. These Newton calls the phenomena of things; but the pride of philosophy is unwilling to admit its ignorance of their causes. From the phenomena, which are the objects of our attempt to infer a cause, which we call God, and gratuitously endow it with all negative and contradictory qualities. From this hypothesis we invent this general name, to conceal our ignorance of causes and essences. The being called God by no means answers with the conditions prescribed by Newton; it bears every mark of a veil woven by philosophical conceit, to hide the ignorance of philosophers even from themselves. They borrow the threads of its texture from the anthropomorphism of the vulgar. Words have been used by sophists for the same purposes, from the occult qualities of the peripatetics to the effuvium of Boyle and the crinities or nebulae of Herschel. God is represented as infinite, eternal, incomprehensible; he is contained under every predicate in non that the logic of ignorance could fabricate. Even his worshippers allow that it is impossible to form any idea of him: they exclaim with the French poet,

Pour dire ce qu'il est, il faut etre lui-meme.

Lord Bacon says that atheism leaves to man reason, philosophy, natural piety, laws, reputation, and everything that can serve to conduct him to virtue; but superstition destroys all these, and erects itself into a tyranny over the understandings of men: hence atheism never disturbs the government, but renders man more clear- sighted, since he sees nothing beyond the boundaries of the present life. -- Bacon's Moral Essays.

The [Beginning here, and to the paragraph ending with Systeme de la Nature," Shelley wrote in French. A free translation has been substituted.] first theology of man made him first fear and adore the elements themselves, the gross and material objects of nature; he next paid homage to the agents controlling the elements, lower genies, heroes or men gifted with great qualities. By force of reflection he sought to simplify things by submitting all nature to a single agent, spirit, or universal soul, which, gave movement to nature and all its branches. Mounting from cause to cause, mortal man has ended by seeing nothing; and it is in this obscurity that he has placed his God; it is in this darksome abyss that his uneasy imagination has always labored to fabricate chimeras, which will continue to afflict him until his knowledge of nature chases these phantoms which he has always so adored.

If we wish to explain our ideas of the Divinity we shall be obliged to admit that, by the word God, man has never been able to designate but the most hidden, the most distant and the most unknown cause of the effects which he saw; he has made use of his word only when the play of natural and known causes ceased to be visible to him; as soon as he lost the thread of these causes, or when his mind could no longer follow the chain, he cut the difficulty and ended his researches by calling God the last of the causes, that is to say, that which is beyond all causes that he knew; thus he but assigned a vague denomination to an unknown cause, at which his laziness or the limits of his knowledge forced him to stop. Every time we say that God is the author of some phenomenon, that signifies that we are ignorant of how such a phenomenon was able to operate by the aid of forces or causes that we know in nature. It is thus that the generality of mankind, whose lot is ignorance, attributes to the Divinity, not only the unusual effects which strike them, but moreover the most simple events, of which the causes are the most simple to understand by whomever is able to study them. In a word, man has always respected unknown causes, surprising effects that his ignorance kept him from unraveling. It was on this debris of nature that man raised the imaginary colossus of the Divinity.

If ignorance of nature gave birth to gods, knowledge of nature is made for their destruction. In proportion as man taught himself, his strength and his resources augmented with his knowledge; science, the arts, industry, furnished him assistance; experience reassured him or procured for him means of resistance to the efforts of many causes which ceased to alarm as soon as they became understood. In a word, his terrors dissipated in the same proportion as his mind became enlightened. The educated man ceases to be superstitious.

It is only by hearsay (by word of mouth passed down from generation to generation) that whole peoples adore the God of their fathers and of their priests: authority, confidence, submission and custom with them take the place of conviction or of proofs: they prostrate themselves and pray, because their fathers taught them to prostrate themselves and pray: but why did their fathers fall on their knees? That is because, in primitive times, their legislators and their guides made it their duty. "Adore and believe," they said, "the gods whom you cannot understand; have confidence in our profound wisdom; we know more than you about Divinity." But why should I come to you? It is because God willed it thus; it is because God will punish you if you dare resist. But this God, is not he, then, the thing in question? However, man has always traveled in this vicious circle; his slothful mind has always made him find it easier to accept the judgment of others. All religious nations are founded solely on authority; all the religions of the world forbid examination and do not want one to reason; authority wants one to believe in God; this God is himself founded only on the authority of a few men who pretend to know him, and to come in his name and announce him on earth. A God made by man undoubtedly has need of man to make himself known to man.

Should it not, then, be for the priests, the inspired, the metaphysicians that should be reserved the conviction of the existence of a God, which they, nevertheless, say is so necessary for all mankind? But Can you find any harmony in the theological opinions of the different inspired ones or thinkers scattered over the earth? They themselves, who make a profession of adoring the same God, are they in Agreement? Are they content with the proofs that their colleagues bring of his existence? Do they subscribe unanimously to the ideas they present on nature, on his conduct, on the manner of understanding his pretended oracles? Is there a country on earth where the science of God is really perfect? Has this science anywhere taken the consistency and uniformity that we the see the science of man assume, even in the most futile crafts, the most despised trades. These words mind immateriality, creation, predestination and grace; this mass of subtle distinctions with which theology to everywhere filled; these so ingenious inventions, imagined by thinkers who have succeeded one another for so many centuries, have only, alas! confused things all the more, and never has man's most necessary science, up to this time acquired the slightest fixity. For thousands of years the lazy dreamers have perpetually relieved one another to meditate on the Divinity, to divine his secret will, to invent the proper hypothesis to develop this important enigma. Their slight success has not discouraged the theological vanity: one always speaks of God: one has his throat cut for God: and this sublime being still remains the most unknown and the most discussed.

Man would have been too happy, if, limiting himself to the visible objects which interested him, he had employed, to perfect his real sciences, his laws, his morals, his education, one-half the efforts he has put into his researches on the Divinity. He would have been still wiser and still more fortunate if he had been satisfied to let his jobless guides quarrel among themselves, sounding depths capable of rendering them dizzy, without himself mixing in their senseless disputes. But it is the essence of ignorance to attach importance to that which it does not understand. Human vanity is so constituted that it stiffens before difficulties. The more an object conceals itself from our eyes, the greater the effort we make to seize it, because it pricks our pride, it excites our curiosity and it appears interesting. In fighting for his God everyone, in fact, fights only for the interests of his own vanity, which, of all the passions produced by the mal-organization of society, is the quickest to take offense, and the most capable of committing the greatest follies.

If, leaving for a moment the annoying idea that theology gives of a capricious God, whose partial and despotic decrees decide the fate of mankind, we wish to fix our eyes only on the pretended goodness, which all men, even trembling before this God, agree is ascribing to him, if we allow him the purpose that is lent him of having worked only for his own glory, of exacting the homage of intelligent beings; of seeking only in his works the well-being of mankind; how reconcile these views and these dispositions with the ignorance truly invincible in which this God, so glorious and so good, leaves the majority of mankind in regard to God himself? If God wishes to be known, cherished, thanked, why does he not show himself under his favorable features to all these intelligent beings by whom he wishes to be loved and adored? Why not manifest himself to the whole earth in an unequivocal manner, much more capable of convincing us than these private revelations which seem to accuse the Divinity of an annoying partiality for some of his creatures? The all-powerful, should he not heave more convincing means by which to show man than these ridiculous metamorphoses, these pretended incarnations, which are attested by writers so little in agreement among themselves? In place of so many miracles, invented to prove the divine mission of so many legislators revered by the different people of the world, the Sovereign of these spirits, could he not convince the human mind in an instant of the things he wished to make known to it? Instead of hanging the sun in the vault of the firmament, instead of scattering stars without order, and the constellations which fill space, would it not have been more in conformity with the views of a God so jealous of his glory and so well-intentioned for mankind, to write, in a manner not subject to dispute, his name, his attributes, his permanent wishes in ineffaceable characters, equally understandable to all the inhabitants of the earth? No one would then be able to doubt the existence of God, of his clear will, of his visible intentions. Under the eyes of this so terrible God no one would have the audacity to violate his commands, no mortal would dare risk attracting his anger: finally, no man would have the effrontery to impose on his name or to interpret his will according to his own fancy.

In fact, even while admitting the existence of the theological God, and the reality of his so discordant attributes which they impute to him, one can conclude nothing to authorize the conduct or the cult which one is prescribed to render him. Theology is truly the sieve of the Danaides. By dint of contradictory qualities and hazarded assertions it has, that is to say, so handicapped its God that it has made it impossible for him to act. If he is infinitely good, what reason should we have to fear him? If he is infinitely wise, why should we have doubts concerning our future? If he knows all, why warn him of our needs and fatigue him with our prayers? If he is everywhere, why erect temples to him? If he is just, why fear that he will punish the creatures that he has, filled with weaknesses? If grace does everything for them, what reason would he have for recompensing them? If he is all-powerful, how offend him, how resist him? If he is reasonable, how can he be angry at the blind, to whom he has given the liberty of being unreasonable? If he is immovable, by what right do we pretend to make him change his decrees? If he is inconceivable, why occupy ourselves with him? IF HE HAS SPOKEN, WHY IS THE UNIVERSE NOT CONVINCED? If the knowledge of a God is the most necessary, why is it not the most evident and the clearest. -- Systame de la Nature. London, 1781.

The enlightened and benevolent Pliny thus Publicly professes himself an atheist, -- Quapropter effigiem Del formamque quaerere imbecillitatis humanae reor. Quisquis est Deus (si modo est alius) et quacunque in parte, totus est gensus, totus est visus, totus auditus, totus animae, totus animi, totus sul. ... Imperfectae vero in homine naturae praecipua solatia, ne deum quidem omnia. Namque nec sibi protest mortem consciscere, si velit, quod homini dedit optimum in tantis vitae poenis; nee mortales aeternitate donare, aut revocare defunctos; nec facere ut qui vixit non vixerit, qui honores gessit non gesserit, nullumque habere In praeteritum ius praeterquam oblivionts, atque (ut. facetis quoque argumentis societas haec cum, deo compuletur) ut bis dena viginti non sint, et multa similiter efficere non posse. -- Per quaedeclaratur haud dubie naturae potentiam id quoque ease quod Deum vocamus. -- Plin. Nat. Hist. cap. de Deo.

The consistent Newtonian is necessarily an atheist. See Sir W. Drummond's Academical Questions, chap. iii. -- Sir W. seems to consider the atheism to which it leads as a sufficient presumption of the falsehood of the system of gravitation; but surely it is more consistent with the good faith of philosophy to admit a deduction from facts than an hypothesis incapable of proof, although it might militate, with the obstinate preconceptions of the mob. Had this author, instead of inveighing against the guilt and absurdity of atheism, demonstrated its falsehood, his conduct would have, been more suited to the modesty of the skeptic and the toleration of the philosopher.

Omnia enim per Dei potentiam facta aunt: imo quia naturae potentia nulla est nisi ipsa Dei potentia. Certum est nos eatenus Dei potentiam non intelligere, quatenus causas naturales ignoramus; adeoque stulte ad eandem Dei potentism recurritur, quando rei alicuius causam naturalem, sive est, ipsam Dei potentiam ignoramusd -- Spinoza, Tract. Theologico-Pol. chap 1. P. 14.
