Dialogues Concerning Natural Religion

by

David Hume

PAMPHILUS TO HERMIPPUS

It has been remarked, my HERMIPPUS, that though the ancient philosophers

conveyed most of their instruction in the form of dialogue, this method

of composition has been little practised in later ages, and has seldom

succeeded in the hands of those who have attempted it. Accurate and

regular argument, indeed, such as is now expected of philosophical

inquirers, naturally throws a man into the methodical and didactic

manner; where he can immediately, without preparation, explain the point

at which he aims; and thence proceed, without interruption, to deduce

the proofs on which it is established. To deliver a SYSTEM in

conversation, scarcely appears natural; and while the dialogue-writer

desires, by departing from the direct style of composition, to give a

freer air to his performance, and avoid the appearance of Author and

Reader, he is apt to run into a worse inconvenience, and convey the

image of Pedagogue and Pupil. Or, if he carries on the dispute in the

natural spirit of good company, by throwing in a variety of topics, and

preserving a proper balance among the speakers, he often loses so much

time in preparations and transitions, that the reader will scarcely

think himself compensated, by all the graces of dialogue, for the order,

brevity, and precision, which are sacrificed to them.

There are some subjects, however, to which dialogue-writing is peculiarly

adapted, and where it is still preferable to the direct and simple method

of composition.

Any point of doctrine, which is so obvious that it scarcely admits of

dispute, but at the same time so important that it cannot be too often

inculcated, seems to require some such method of handling it; where the

novelty of the manner may compensate the triteness of the subject; where

the vivacity of conversation may enforce the precept; and where the

variety of lights, presented by various personages and characters, may

appear neither tedious nor redundant.

Any question of philosophy, on the other hand, which is so OBSCURE and

UNCERTAIN, that human reason can reach no fixed determination with regard

to it; if it should be treated at all, seems to lead us naturally into

the style of dialogue and conversation. Reasonable men may be allowed to

differ, where no one can reasonably be positive. Opposite sentiments,

even without any decision, afford an agreeable amusement; and if the

subject be curious and interesting, the book carries us, in a manner,

into company; and unites the two greatest and purest pleasures of human

life, study and society.

Happily, these circumstances are all to be found in the subject of

NATURAL RELIGION. What truth so obvious, so certain, as the being of a

God, which the most ignorant ages have acknowledged, for which the most

refined geniuses have ambitiously striven to produce new proofs and

arguments? What truth so important as this, which is the ground of all

our hopes, the surest foundation of morality, the firmest support of

society, and the only principle which ought never to be a moment absent

from our thoughts and meditations? But, in treating of this obvious and

important truth, what obscure questions occur concerning the nature of

that Divine Being, his attributes, his decrees, his plan of providence?

These have been always subjected to the disputations of men; concerning

these human reason has not reached any certain determination. But these

are topics so interesting, that we cannot restrain our restless inquiry

with regard to them; though nothing but doubt, uncertainty, and

contradiction, have as yet been the result of our most accurate

researches.

This I had lately occasion to observe, while I passed, as usual, part of

the summer season with CLEANTHES, and was present at those conversations

of his with PHILO and DEMEA, of which I gave you lately some imperfect

account. Your curiosity, you then told me, was so excited, that I must,

of necessity, enter into a more exact detail of their reasonings, and

display those various systems which they advanced with regard to so

delicate a subject as that of natural religion. The remarkable contrast

in their characters still further raised your expectations; while you

opposed the accurate philosophical turn of CLEANTHES to the careless

scepticism of PHILO, or compared either of their dispositions with the

rigid inflexible orthodoxy of DEMEA. My youth rendered me a mere auditor

of their disputes; and that curiosity, natural to the early season of

life, has so deeply imprinted in my memory the whole chain and connection

of their arguments, that, I hope, I shall not omit or confound any

considerable part of them in the recital.

PART 1

After I joined the company, whom I found sitting in CLEANTHES's library,

DEMEA paid CLEANTHES some compliments on the great care which he took of

my education, and on his unwearied perseverance and constancy in all his

friendships. The father of PAMPHILUS, said he, was your intimate friend:

The son is your pupil; and may indeed be regarded as your adopted son,

were we to judge by the pains which you bestow in conveying to him every

useful branch of literature and science. You are no more wanting, I am

persuaded, in prudence, than in industry. I shall, therefore, communicate

to you a maxim, which I have observed with regard to my own children,

that I may learn how far it agrees with your practice. The method I

follow in their education is founded on the saying of an ancient, "That

students of philosophy ought first to learn logics, then ethics, next

physics, last of all the nature of the gods." [Chrysippus apud Plut: de

repug: Stoicorum] This science of natural theology, according to him,

being the most profound and abstruse of any, required the maturest

judgement in its students; and none but a mind enriched with all the other

sciences, can safely be entrusted with it.

Are you so late, says PHILO, in teaching your children the principles of

religion? Is there no danger of their neglecting, or rejecting altogether

those opinions of which they have heard so little during the whole course

of their education? It is only as a science, replied DEMEA, subjected to

human reasoning and disputation, that I postpone the study of Natural

Theology. To season their minds with early piety, is my chief care; and

by continual precept and instruction, and I hope too by example, I

imprint deeply on their tender minds an habitual reverence for all the

principles of religion. While they pass through every other science, I

still remark the uncertainty of each part; the eternal disputations of

men; the obscurity of all philosophy; and the strange, ridiculous

conclusions, which some of the greatest geniuses have derived from the

principles of mere human reason. Having thus tamed their mind to a proper

submission and self-diffidence, I have no longer any scruple of opening

to them the greatest mysteries of religion; nor apprehend any danger from

that assuming arrogance of philosophy, which may lead them to reject the

most established doctrines and opinions.

Your precaution, says PHILO, of seasoning your children's minds early

with piety, is certainly very reasonable; and no more than is requisite

in this profane and irreligious age. But what I chiefly admire in your

plan of education, is your method of drawing advantage from the very

principles of philosophy and learning, which, by inspiring pride and

self-sufficiency, have commonly, in all ages, been found so destructive

to the principles of religion. The vulgar, indeed, we may remark, who are

unacquainted with science and profound inquiry, observing the endless

disputes of the learned, have commonly a thorough contempt for

philosophy; and rivet themselves the faster, by that means, in the great

points of theology which have been taught them. Those who enter a little

into study and inquiry, finding many appearances of evidence in

doctrines the newest and most extraordinary, think nothing too difficult

for human reason; and, presumptuously breaking through all fences,

profane the inmost sanctuaries of the temple. But CLEANTHES will, I hope,

agree with me, that, after we have abandoned ignorance, the surest

remedy, there is still one expedient left to prevent this profane

liberty. Let DEMEA's principles be improved and cultivated: Let us become

thoroughly sensible of the weakness, blindness, and narrow limits of

human reason: Let us duly consider its uncertainty and endless

contrarieties, even in subjects of common life and practice: Let the

errors and deceits of our very senses be set before us; the insuperable

difficulties which attend first principles in all systems; the

contradictions which adhere to the very ideas of matter, cause and

effect, extension, space, time, motion; and in a word, quantity of all

kinds, the object of the only science that can fairly pretend to any

certainty or evidence. When these topics are displayed in their full

light, as they are by some philosophers and almost all divines; who can

retain such confidence in this frail faculty of reason as to pay any

regard to its determinations in points so sublime, so abstruse, so remote

from common life and experience? When the coherence of the parts of a

stone, or even that composition of parts which renders it extended; when

these familiar objects, I say, are so inexplicable, and contain

circumstances so repugnant and contradictory; with what assurance can we

decide concerning the origin of worlds, or trace their history from

eternity to eternity?

While PHILO pronounced these words, I could observe a smile in the

countenance both of DEMEA and CLEANTHES. That of DEMEA seemed to imply an

unreserved satisfaction in the doctrines delivered: But, in CLEANTHES's

features, I could distinguish an air of finesse; as if he perceived some

raillery or artificial malice in the reasonings of PHILO.

You propose then, PHILO, said CLEANTHES, to erect religious faith on

philosophical scepticism; and you think, that if certainty or evidence be

expelled from every other subject of inquiry, it will all retire to these

theological doctrines, and there acquire a superior force and authority.

Whether your scepticism be as absolute and sincere as you pretend, we

shall learn by and by, when the company breaks up: We shall then see,

whether you go out at the door or the window; and whether you really

doubt if your body has gravity, or can be injured by its fall; according

to popular opinion, derived from our fallacious senses, and more

fallacious experience. And this consideration, DEMEA, may, I think,

fairly serve to abate our ill-will to this humorous sect of the sceptics.

If they be thoroughly in earnest, they will not long trouble the world

with their doubts, cavils, and disputes: If they be only in jest, they

are, perhaps, bad raillers; but can never be very dangerous, either to

the state, to philosophy, or to religion.

In reality, PHILO, continued he, it seems certain, that though a man, in

a flush of humour, after intense reflection on the many contradictions

and imperfections of human reason, may entirely renounce all belief and

opinion, it is impossible for him to persevere in this total scepticism,

or make it appear in his conduct for a few hours. External objects press

in upon him; passions solicit him; his philosophical melancholy

dissipates; and even the utmost violence upon his own temper will not be

able, during any time, to preserve the poor appearance of scepticism. And

for what reason impose on himself such a violence? This is a point in

which it will be impossible for him ever to satisfy himself, consistently

with his sceptical principles. So that, upon the whole, nothing could be

more ridiculous than the principles of the ancient PYRRHONIANS; if in

reality they endeavoured, as is pretended, to extend, throughout, the

same scepticism which they had learned from the declamations of their

schools, and which they ought to have confined to them.

In this view, there appears a great resemblance between the sects of the

STOICS and PYRRHONIANS, though perpetual antagonists; and both of them

seem founded on this erroneous maxim, That what a man can perform

sometimes, and in some dispositions, he can perform always, and in every

disposition. When the mind, by Stoical reflections, is elevated into a

sublime enthusiasm of virtue, and strongly smit with any species of

honour or public good, the utmost bodily pain and sufferings will not

prevail over such a high sense of duty; and it is possible, perhaps, by

its means, even to smile and exult in the midst of tortures. If this

sometimes may be the case in fact and reality, much more may a

philosopher, in his school, or even in his closet, work himself up to

such an enthusiasm, and support in imagination the acutest pain or most

calamitous event which he can possibly conceive. But how shall he support

this enthusiasm itself? The bent of his mind relaxes, and cannot be

recalled at pleasure; avocations lead him astray; misfortunes attack him

unawares; and the philosopher sinks by degrees into the plebeian.

I allow of your comparison between the STOICS and SKEPTICS, replied

PHILO. But you may observe, at the same time, that though the mind

cannot, in Stoicism, support the highest flights of philosophy, yet, even

when it sinks lower, it still retains somewhat of its former disposition;

and the effects of the Stoic's reasoning will appear in his conduct in

common life, and through the whole tenor of his actions. The ancient

schools, particularly that of ZENO, produced examples of virtue and

constancy which seem astonishing to present times.

Vain Wisdom all and false Philosophy.

Yet with a pleasing sorcery could charm

Pain, for a while, or anguish; and excite

Fallacious Hope, or arm the obdurate breast

With stubborn Patience, as with triple steel.

In like manner, if a man has accustomed himself to sceptical

considerations on the uncertainty and narrow limits of reason, he will

not entirely forget them when he turns his reflection on other subjects;

but in all his philosophical principles and reasoning, I dare not say in

his common conduct, he will be found different from those, who either

never formed any opinions in the case, or have entertained sentiments

more favourable to human reason.

To whatever length any one may push his speculative principles of

scepticism, he must act, I own, and live, and converse, like other men;

and for this conduct he is not obliged to give any other reason, than the

absolute necessity he lies under of so doing. If he ever carries his

speculations further than this necessity constrains him, and

philosophises either on natural or moral subjects, he is allured by a

certain pleasure and satisfaction which he finds in employing himself

after that manner. He considers besides, that every one, even in common

life, is constrained to have more or less of this philosophy; that from

our earliest infancy we make continual advances in forming more general

principles of conduct and reasoning; that the larger experience we

acquire, and the stronger reason we are endued with, we always render our

principles the more general and comprehensive; and that what we call

philosophy is nothing but a more regular and methodical operation of the

same kind. To philosophise on such subjects, is nothing essentially

different from reasoning on common life; and we may only expect greater

stability, if not greater truth, from our philosophy, on account of its

exacter and more scrupulous method of proceeding.

But when we look beyond human affairs and the properties of the

surrounding bodies: when we carry our speculations into the two

eternities, before and after the present state of things; into the

creation and formation of the universe; the existence and properties of

spirits; the powers and operations of one universal Spirit existing

without beginning and without end; omnipotent, omniscient, immutable,

infinite, and incomprehensible: We must be far removed from the smallest

tendency to scepticism not to be apprehensive, that we have here got

quite beyond the reach of our faculties. So long as we confine our

speculations to trade, or morals, or politics, or criticism, we make

appeals, every moment, to common sense and experience, which strengthen

our philosophical conclusions, and remove, at least in part, the

suspicion which we so justly entertain with regard to every reasoning

that is very subtle and refined. But, in theological reasonings, we have

not this advantage; while, at the same time, we are employed upon

objects, which, we must be sensible, are too large for our grasp, and of

all others, require most to be familiarised to our apprehension. We are

like foreigners in a strange country, to whom every thing must seem

suspicious, and who are in danger every moment of transgressing against

the laws and customs of the people with whom they live and converse. We

know not how far we ought to trust our vulgar methods of reasoning in

such a subject; since, even in common life, and in that province which is

peculiarly appropriated to them, we cannot account for them, and are

entirely guided by a kind of instinct or necessity in employing them.

All sceptics pretend, that, if reason be considered in an abstract view,

it furnishes invincible arguments against itself; and that we could never

retain any conviction or assurance, on any subject, were not the

sceptical reasonings so refined and subtle, that they are not able to

counterpoise the more solid and more natural arguments derived from the

senses and experience. But it is evident, whenever our arguments lose

this advantage, and run wide of common life, that the most refined

scepticism comes to be upon a footing with them, and is able to oppose

and counterbalance them. The one has no more weight than the other. The

mind must remain in suspense between them; and it is that very suspense

or balance, which is the triumph of scepticism.

But I observe, says CLEANTHES, with regard to you, PHILO, and all

speculative sceptics, that your doctrine and practice are as much at

variance in the most abstruse points of theory as in the conduct of

common life. Wherever evidence discovers itself, you adhere to it,

notwithstanding your pretended scepticism; and I can observe, too, some

of your sect to be as decisive as those who make greater professions of

certainty and assurance. In reality, would not a man be ridiculous, who

pretended to reject NEWTON's explication of the wonderful phenomenon of

the rainbow, because that explication gives a minute anatomy of the rays

of light; a subject, forsooth, too refined for human comprehension? And

what would you say to one, who, having nothing particular to object to

the arguments of COPERNICUS and GALILEO for the motion of the earth,

should withhold his assent, on that general principle, that these

subjects were too magnificent and remote to be explained by the narrow

and fallacious reason of mankind?

There is indeed a kind of brutish and ignorant scepticism, as you well

observed, which gives the vulgar a general prejudice against what they do

not easily understand, and makes them reject every principle which

requires elaborate reasoning to prove and establish it. This species of

scepticism is fatal to knowledge, not to religion; since we find, that

those who make greatest profession of it, give often their assent, not

only to the great truths of Theism and natural theology, but even to the

most absurd tenets which a traditional superstition has recommended to

them. They firmly believe in witches, though they will not believe nor

attend to the most simple proposition of Euclid. But the refined and

philosophical sceptics fall into an inconsistence of an opposite nature.

They push their researches into the most abstruse corners of science; and

their assent attends them in every step, proportioned to the evidence

which they meet with. They are even obliged to acknowledge, that the most

abstruse and remote objects are those which are best explained by

philosophy. Light is in reality anatomised. The true system of the

heavenly bodies is discovered and ascertained. But the nourishment of

bodies by food is still an inexplicable mystery. The cohesion of the

parts of matter is still incomprehensible. These sceptics, therefore, are

obliged, in every question, to consider each particular evidence apart,

and proportion their assent to the precise degree of evidence which

occurs. This is their practice in all natural, mathematical, moral, and

political science. And why not the same, I ask, in the theological and

religious? Why must conclusions of this nature be alone rejected on the

general presumption of the insufficiency of human reason, without any

particular discussion of the evidence? Is not such an unequal conduct a

plain proof of prejudice and passion?

Our senses, you say, are fallacious; our understanding erroneous; our

ideas, even of the most familiar objects, extension, duration, motion,

full of absurdities and contradictions. You defy me to solve the

difficulties, or reconcile the repugnancies which you discover in them. I

have not capacity for so great an undertaking: I have not leisure for it:

I perceive it to be superfluous. Your own conduct, in every circumstance,

refutes your principles, and shows the firmest reliance on all the

received maxims of science, morals, prudence, and behaviour.

I shall never assent to so harsh an opinion as that of a celebrated

writer [L'Arte de penser], who says, that the Sceptics are not a sect of

philosophers: They are only a sect of liars. I may, however, affirm

(I hope without offence), that they are a sect of jesters or raillers.

But for my part, whenever I find myself disposed to mirth and amusement,

I shall certainly choose my entertainment of a less perplexing and abstruse

nature. A comedy, a novel, or at most a history, seems a more natural

recreation than such metaphysical subtleties and abstractions.

In vain would the sceptic make a distinction between science and common

life, or between one science and another. The arguments employed in all,

if just, are of a similar nature, and contain the same force and

evidence. Or if there be any difference among them, the advantage lies

entirely on the side of theology and natural religion. Many principles of

mechanics are founded on very abstruse reasoning; yet no man who has any

pretensions to science, even no speculative sceptic, pretends to

entertain the least doubt with regard to them. The COPERNICAN system

contains the most surprising paradox, and the most contrary to our

natural conceptions, to appearances, and to our very senses: yet even

monks and inquisitors are now constrained to withdraw their opposition to

it. And shall PHILO, a man of so liberal a genius and extensive

knowledge, entertain any general undistinguished scruples with regard to

the religious hypothesis, which is founded on the simplest and most

obvious arguments, and, unless it meets with artificial obstacles, has

such easy access and admission into the mind of man?

And here we may observe, continued he, turning himself towards DEMEA, a

pretty curious circumstance in the history of the sciences. After the

union of philosophy with the popular religion, upon the first

establishment of Christianity, nothing was more usual, among all

religious teachers, than declamations against reason, against the senses,

against every principle derived merely from human research and inquiry.

All the topics of the ancient academics were adopted by the fathers; and

thence propagated for several ages in every school and pulpit throughout

Christendom. The Reformers embraced the same principles of reasoning, or

rather declamation; and all panegyrics on the excellency of faith, were

sure to be interlarded with some severe strokes of satire against natural

reason. A celebrated prelate [Monsr. Huet] too, of the Romish communion,

a man of the most extensive learning, who wrote a demonstration of

Christianity, has also composed a treatise, which contains all the cavils

of the boldest and most determined PYRRHONISM. LOCKE seems to have been the

first Christian who ventured openly to assert, that faith was nothing but

a species of reason; that religion was only a branch of philosophy; and

that a chain of arguments, similar to that which established any truth in

morals, politics, or physics, was always employed in discovering all the

principles of theology, natural and revealed. The ill use which BAYLE and

other libertines made of the philosophical scepticism of the fathers and

first reformers, still further propagated the judicious sentiment of Mr.

LOCKE: And it is now in a manner avowed, by all pretenders to reasoning

and philosophy, that Atheist and Sceptic are almost synonymous. And as it

is certain that no man is in earnest when he professes the latter

principle, I would fain hope that there are as few who seriously maintain

the former.

Don't you remember, said PHILO, the excellent saying of LORD BACON on

this head? That a little philosophy, replied CLEANTHES, makes a man an

Atheist: A great deal converts him to religion. That is a very judicious

remark too, said PHILO. But what I have in my eye is another passage,

where, having mentioned DAVID's fool, who said in his heart there is no

God, this great philosopher observes, that the Atheists nowadays have a

double share of folly; for they are not contented to say in their hearts

there is no God, but they also utter that impiety with their lips, and

are thereby guilty of multiplied indiscretion and imprudence. Such

people, though they were ever so much in earnest, cannot, methinks, be

very formidable.

But though you should rank me in this class of fools, I cannot forbear

communicating a remark that occurs to me, from the history of the

religious and irreligious scepticism with which you have entertained us.

It appears to me, that there are strong symptoms of priestcraft in the

whole progress of this affair. During ignorant ages, such as those which

followed the dissolution of the ancient schools, the priests perceived,

that Atheism, Deism, or heresy of any kind, could only proceed from the

presumptuous questioning of received opinions, and from a belief that

human reason was equal to every thing. Education had then a mighty

influence over the minds of men, and was almost equal in force to those

suggestions of the senses and common understanding, by which the most

determined sceptic must allow himself to be governed. But at present,

when the influence of education is much diminished, and men, from a more

open commerce of the world, have learned to compare the popular

principles of different nations and ages, our sagacious divines have

changed their whole system of philosophy, and talk the language of

STOICS, PLATONISTS, and PERIPATETICS, not that of PYRRHONIANS and

ACADEMICS. If we distrust human reason, we have now no other principle to

lead us into religion. Thus, sceptics in one age, dogmatists in another;

whichever system best suits the purpose of these reverend gentlemen, in

giving them an ascendant over mankind, they are sure to make it their

favourite principle, and established tenet.

It is very natural, said CLEANTHES, for men to embrace those principles,

by which they find they can best defend their doctrines; nor need we have

any recourse to priestcraft to account for so reasonable an expedient.

And, surely nothing can afford a stronger presumption, that any set of

principles are true, and ought to be embraced, than to observe that they

tend to the confirmation of true religion, and serve to confound the

cavils of Atheists, Libertines, and Freethinkers of all denominations.
