In conducting ourselves in this manner, our reason prescribes a

morality agreeable to nature, reasonable to all, constant in its

operation, effective in its exercise in benefiting all, in

contributing to the happiness of society, collectively and

individually, in distinction to the mysticism preached up by priests.

We shall find in our reason and in our nature the surest guides,

superior to the clergy, who only teach us to benefit themselves. We

shall thus enjoy a morality as durable as the race of man. We shall

have precepts founded on the necessity of things, that will punish

those transgressing them, and rewarding those who obey them. Every

man who shall prove himself to be just, useful, beneficent, will be an

object of love to his fellow-citizens; every man who shall prove

himself unjust, useless, and wicked will become an object of hatred to

himself as well as to others; he will be forced to tremble at the

violation of the laws; he will be compelled to do that which is good

to gain the good will of mankind and preserve the regard of those who

have the power of obliging him to be a useful member of the state.

Thus, Madam, if it should be demanded of you what you would substitute

for the benefit of society, in place of visionary reveries, I reply, a

sensible morality, a good education, profitable habits, self-evident

principles of duty, wise laws, which even the wicked cannot

misunderstand, but which may correct their evil purposes, and

recompenses that may tend to the promotion of virtue. The education of

the present day tends only to make youth the slaves of superstition;

the virtues which it inculcates on them are only those of fanaticism,

to render the mind subject to the priests for the remainder of life;

the motives to duty are only fictitious and imaginary; the rewards and

punishments which it exhibits in an obscure glimmering, produce no

other effect than to make useless enthusiasts and dangerous fanatics.

The principles on which enthusiasm establishes morality are changing

and ruinous; those on which the morality of reason is established are

fixed, and cannot be overturned. Seeing, then, that man, a reasonable

being, should be chiefly occupied about his preservation and

happiness--that he should love virtue--that he should be sensible of

its advantages--that he should fear the consequences of crime--is it

to be wondered I should insist so much on the practice of virtue as

his chief good? Men ought to hate crime because it leads to misery.

Society, to exist, must receive the united virtue of its members,

obedience to good laws, the activity and intelligence of citizens to

defend its privileges and its rights. Laws are good when they invite

the members of society to labor for reciprocal good offices. Laws are

just when they recompense or punish in proportion to the good or evil

which is done to society. Laws supported by a visible authority should

be founded on present motives; and thus they would have more force

than those of religion, which are founded on uncertain motives,

imaginary and removed from this world, and which experience proves

cannot suffice to curb the passions of bad men, nor show them their

duty by the fear of punishments after death.

If in place of stifling human reason, as is too much done, its

perfectibility were studied; if in place of deluging the world with

visionary notions, truth were inculcated; if in place of pleading a

supernatural morality, a morality agreeable to humanity and resulting

from experience were preached, we should no longer be the dupes of

imaginary theories, nor of terrifying fables as the bases of virtue.

Every one would then perceive that it is to the practice of virtue, to

the faithful observation of the duties of morality, that the happiness

of individuals and of society is to be traced. Is he a husband? He

will perceive that his essential happiness is to show kindness,

attachment, and tenderness to the companion of his life, destined by

his own choice to share his pleasures and endure his misfortunes. And,

on the other hand, she, by consulting her true interests, will

perceive that they consist in rendering homage to her husband, in

interdicting every thought that could alienate her affections,

diminish her esteem and confidence in him. Fathers and mothers will

perceive that their children are destined to be one day their

consolation and support in old age, and that by consequence they have

the greatest interest in inspiring them in early life with sentiments

of which they may themselves reap the benefit when age or misfortune

may require the fruits of those advantages that result from a good

education. Their children early taught to reflect on these things,

will find their interest to lie in meriting the kindness of their

parents, and in giving them proofs that the virtues they are taught

will be communicated to their posterity. The master will perceive

that, to be served with affection, he owes good will, kindness, and

indulgence to those at whose hands he would reap advantages, and by

whose labor he would increase his prosperity; and servants will

discover how much their happiness depends on fidelity, industry, and

good temper in their situations. Friends will find the advantages of a

kindred heart for friendship, and the reciprocity of good offices. The

members of the same family will perceive the necessity of preserving

that union which nature has established among them, to render mutual

benefits in prosperity or in adversity. Societies, if they reflect on

the end of their association, will perceive that to secure it they

must observe good faith and punctuality in their engagements. The

citizen, when he consults his reason, will perceive how much it is

necessary, for the good of the nation to which he belongs, that he

should exert himself to advance its prosperity, or, in its

misfortunes, to retrieve its glory. By consequence every one in his

sphere, and using his faculties for this great end, will find his own

advantage in restraining the bad as dangerous, and opposing enemies to

the state as enemies to himself.

In a word, every man who will reflect for himself will be compelled to

acknowledge the necessity of virtue for the happiness of the world. It

is so obvious that justice is the basis of all society; that good will

and good offices necessarily procure for men affection and respect;

that every man who respects himself ought to seek the esteem of

others; that it is necessary to merit the good opinion of society;

that he ought to be jealous of his reputation; that a weak being, who

is every instant exposed to misfortunes, ought to know what are his

duties, and how he should practise them for the benefit of himself

and the assembly of which he is a member.

If we reflect for one moment on the effects of the passions, we shall

perceive the necessity of repressing them, if we would spare ourselves

vain regrets and useless sorrows, which certainly always afflict those

who obey not the laws. Thus, a single reflection will suffice to show

the impropriety of anger, the dreadful consequences of revenge,

calumny, and backbiting. Every one must perceive that in giving a free

course to unbridled desires, he becomes the enemy of society, and then

it is the part of the laws to restrain him who renounces his reason

and despises the motives that ought to guide him.

If it is objected that man is not a free agent, and therefore is

unable to restrain his passions, and that consequently the law ought

not to punish him, I reply that the community are impelled by the same

necessity to hate what is injurious, and for their own conservation

and happiness have the right to restrain an unhappily organized

individual who is impelled to injure himself and others. The

inevitable faults of men necessarily excite the hatred of those who

suffer from them.

If the man who consults his reason has real and powerful motives for

doing good to others and abstaining from injuring them, he has present

motives equally urgent to restrain him from the commission of vice.

Experience may suffice to show him that if he becomes sooner or later

the victim of his excesses, he ceases to be the friend of virtue, and

exists only to serve vice, which will infallibly punish him. This

being allowed, prudence, or the desire of preserving one's self free

from the contamination of evil, ought to inculcate to every man his

path of duty; and, unless blinded by his passions, he must perceive

how much moderation in his pleasures, temperance, chastity, contribute

to happiness; that those who transgress in these respects are

necessarily the victims of ill health, and too often pass a life both

infirm and unfortunate, which terminates soon in death.

How is it possible, then, Madam, from visionary theories to arrive at

these conclusions, and establish from supernatural phantasms the

principles of private and public virtue? Shall we launch into unknown

regions to ascertain our duty and to keep our station in society? Is

it not sufficient if we wish to be happy that we should endeavor to

preserve ourselves in those maxims which reason approves, and on which

virtue is founded? Every man who would perish, who would render his

existence miserable, whoever would sacrifice permanent happiness for

present pleasure, is a fool, who reflects not on the interests that

are dearest to him.

If there are any principles so clear as the morality of humanity has

been and is still proved to be, they are such as men ought to observe.

They are not obscure notions, mysticism, contradictions, which have

made of a science the most obvious and best demonstrated, an

unintelligible science, mysterious and uncertain to those for whom it

is designed. In the hands of the priests, morality has become an

enigma; they have founded our duties on the attributes of a Deity whom

the mind of man cannot comprehend, in place of founding them on the

character of man himself. They have thrown in among them the

foundations of an edifice which is made for this earth. They have

desired to regulate our manners agreeably to equivocal oracles which

every instant contradict themselves, and which too often render their

devotees useless to society and to themselves. They have pretended to

render their morality more sacred by inviting us to look for

recompenses and punishments removed beyond this life, but which they

announce in the name of the Divinity. In fine, they have made man a

being who may not even strive at perfection, by a preordination of

some to bliss, and consequent damnation of others, whose insensibility

is the result of this selection.

Need we not, then, wonder that this supernatural morality should be so

contrary to the nature and the mind of man? It is in vain that it aims

at the annihilation of human nature, which is so much stronger, so

much more powerful, than imagination. In despite of all the subtile

and marvellous speculations of the priests, man continues always to

love himself, to desire his well being, and to flee misfortune and

sorrow. He has then always been actuated by the same passions. When

these passions have been moderate, and have tended to the public

good, they are legitimate, and we approve those actions which are

their effects. When these passions have been disordered, hurtful to

society, or to the individual, he condemns them; they punish him; he

is dissatisfied with his conduct which others cannot approve. Man

always loves his pleasures, because in their enjoyment he fulfils the

end of his existence; if he exceeds their just bounds he renders

himself miserable.

The morality of the clergy, on the other hand, appears calculated to

keep nature always at variance with herself, for it is almost always

without effect even on the priesthood. Their chimeras serve but to

torture weak minds, and to set the passions at war with nature and

their dogmas. When this morality professes to restrain the wicked, to

curb the passions of men, it operates in opposition to the established

laws of natural religion; for by preserving all its rigor, it becomes

impracticable; and it meets with real devotees only in some few

fanatics who have renounced nature, and who would be singular, even if

their oddities were injurious to society. This morality, adopted for

the most part by devotees, without eradicating their habits or their

natural defects, keeps them always in a state of opposition even with

themselves. Their life is a round of faults and of scruples, of sins

and remorse, of crimes and expiations, of pleasures which they enjoy,

but for which they again reproach themselves for having tasted. In a

word, the morality of superstition necessarily carries with it into

the heart and the family of its devotees inward distress and

affliction; it makes of enthusiasts and fanatics scrupulous devotees;

it makes a great many insensible and miserable; it renders none

perfect, few good; and those only tolerable whom nature, education,

and habit had moulded for happiness.

It is our temperament which decides our condition; the acquisition of

moderate passions, of honest habits, sensible opinions, laudable

examples, and practical virtues, is a difficult task, but not

impossible when undertaken with reason for one's guide. It is

difficult to be virtuous and happy with a temperament so ardent as to

sway the passions to its will. One must in calmness consult reason as

to his duty. Nature, in giving us lively passions and a susceptible

imagination, has made us capable of suffering the instant we

transgress her bounds. She then renders us necessary to ourselves, and

we cannot proceed to consult our real interest if we continue in

indulgence that she forbids. The passions which reason cannot restrain

are not to be bridled by religion. It is in vain that we hope to

derive succors from religion if we despise and refuse what nature

offers us. Religion leaves men just such as nature and habit have made

them; and if it produce any changes on some few, I believe I have

proved that those changes are not always for the better.

Congratulate yourself, then, Madam, on being born with good

dispositions, of having received honest principles, which shall carry

you through life in the practice of virtue, and in the love of a fine

and exalted taste for the rational pleasures of our nature. Continue

to be the happiness of your family, which esteems and honors you.

Continue to diffuse around you the blessings you enjoy; continue to

perform only those actions which are esteemed by all the world, and

all men will respect you. Respect yourself, and others will respect

you. These are the legitimate sentiments of virtue and of happiness.

Labor for your own happiness, and you will promote that of your

family, who will love you in proportion to the good you do it. Allow

me to congratulate myself if, in all I have said, I have in any

measure swept from your mind those clouds of fanaticism which obscure

the reason; and to felicitate you on your having escaped from vague

theories of imagination. Abjure superstition, which is calculated only

to make you miserable; let the morality of humanity be your uniform

religion; that your happiness may be constant, let reason be your

guide; that virtue may be the idol of your soul, cultivate and love

only what is virtuous and good in the world; and if there be a God who

is interested in the happiness of his creatures, if there be a God

full of justice and goodness, he will not be angry with you for having

consulted your reason; if there be another life, your happiness in it

cannot be doubtful, if God rewards every one according to the good

done here.

I am, with respect, &c.

LETTER XII.

Of the small Consequence to be attached to Men's Speculations, and

the Indulgence which should be extended to them.

Permit me, Madam, to felicitate you on the happy change which you say

has taken place in your opinions. Convinced by reasons as simple as

obvious, your mind has become sensible of the futility of those

notions which have for a long time agitated it; and the inefficacy of

those pretended succors which religious men boasted they could

furnish, is now apparent to you. You perceive the evident dangers

which result from a system that serves only to render men enemies to

individual and general happiness. I see with pleasure that reason has

not lost its authority over your mind, and that it is sufficient to

show you the truth that you may embrace it. You may congratulate

yourself on this, which proves the solidity of your judgment. For it

is glorious to give one's self up to reason, and to be the votary of

common sense. Prejudice so arms mankind that the world is full of

people who slight their judgment; nay, who resist the most obvious

pleas of their understanding. Their eyes, long shut to the light of

truth, are unable to bear its rays; but they can endure the

glimmerings of superstition, which plunges them in still darker

obscurity.

I am not, however, astonished at the embarrassment you have hitherto

felt, nor at your cautious examination of my opinions, which are

better understood the more thoroughly they are examined and compared

with those they oppose. It is impossible to annihilate at once

deep-rooted prejudices. The mind of man appears to waver in a void

when those ideas are attacked on which it has long rested. It finds

itself in a new world, wherein all is unknown. Every system of opinion

is but the effect of habit. The mind has as great difficulty to

disengage itself from its custom of thinking, and reflect on new

ideas, as the body has to remain quiescent after it has long been

accustomed to exercise. Should you, for instance, propose to your

friend to leave off snuff, as a practice neither healthful nor

agreeable in company, he will not probably listen to you, or if he

should, it will be with extreme pain that he can bring himself to

renounce a habit long familiarized to him.

It is precisely the same with all our prejudices; those of religion

have the most powerful hold of us. From infancy we have been

familiarized with them; habit has made them a sort of want we cannot

dispense with: our mode of thinking is formed, and familiar to us; our

mind is accustomed to engage itself with certain classes of objects;

and our imagination fancies that it wanders in chaos when it is not

fed with those chimeras to which it had been long accustomed. Phantoms

the most horrible are even clear to it; objects the most familiar to

it, if viewed with the calm eye of reason, are disagreeable and

revolting.

Religion, or rather its superstitions, in consequence of the

marvellous and bizarre notions it engenders, gives the mind continual

exercise; and its votaries fancy they are doomed to a dangerous

inaction when they are suddenly deprived of the objects on which their

imagination exerted its powers. Yet is this exercise so much the more

necessary as the imagination is by far the most lively faculty of the

mind. Hence, without doubt, it becomes necessary men should replace

stale fooleries by those which are novel. This is, moreover, the true

reason why devotion so often affords consolation in great disgraces,

gives diversion for chagrin, and replaces the strongest passions, when

they have been quenched by excess of pleasure and dissipation. The

marvellous arguments, chimeras multiply as religion furnishes activity

and occupation to the fancy; habit renders them familiar, and even

necessary; terrors themselves even minister food to the imagination;

and religion, the religion of priestcraft, is full of terrors. Active

and unquiet spirits continually require this nourishment; the

imagination requires to be alternately alarmed and consoled; and there

are thousands who cannot accustom themselves to tranquillity and the

sobriety of reason. Many persons also require phantoms to make them

religious, and they find these succors in the dogmas of priestcraft.

These reflections will serve to explain to you the continual

variations to which many persons are subject, especially on the

subject of religion. Sensible, like barometers, you behold them

wavering without ceasing; their imagination floats, and is never

fixed; so often as you find them freely given up to the blackness of

superstition, so often may you behold them the slaves of pernicious

prejudices. Whenever they tremble at the feet of their priests, then

are their necks under the yoke. Even people of spirit and

understanding in other affairs are not altogether exempt from these

variations of mental religious temperament; but their judgment is too

frequently the dupe of the imagination. And others, again, timid and

doubting, without spirit, are in perpetual torment.

What do I say? Man is not, and cannot always be, the same. His frame

is exposed to revolutions and perpetual vicissitudes; the thoughts of

his mind necessarily vary with the different degrees of changes to

which his body is exposed. When the body is languid and fatigued, the

mind has not usually much inclination to vigor and gayety. The

debility of the nerves commonly annihilates the energies of the soul,

although it be so remarkably distinguished from the body; persons of a

bilious and melancholy temperament are rarely the subjects of joy;

dissipation importunes some, gayety fatigues others. Exactly after the

same fashion, there are some who love to nourish sombre ideas, and

these religion supplies them. Devotion affects them like the vapors;

superstition is an inveterate malady, for which there is no cure in

medicine. And it is impossible to keep him free from superstition,

whose breast, the slave of fear, was never sensible of courage; nay,

soldiers and sailors, the bravest of men, have too often been the

victims of superstition. It is education alone that operates in

radically curing the human mind of its errors.

Those who think it sufficient, Madam, to render a reason for the

variations which we so frequently remark in the ideas of men,

acknowledge that there is a secret bent of the minds of religious

persons to prejudices, from which we shall almost in vain endeavor to

rescue their understandings. You perceive, at present, what you ought

to think of those secret transitions which our priests would force on

you, as the inspirations of heaven, as divine solicitations, the

effects of grace; though they are, nevertheless, only the effects of

those vicissitudes to which our constitution is liable, and which

affect the robust, as well as the feeble; the man of health, as well

as the valetudinarian.

If we might form a judgment of the correctness of those notions which

our teachers boast of, in respect to our dissolution at death, we

shall find reason to be satisfied, that there is little or no occasion

that we should have our minds disturbed during our last moments. It is

then, say they, that it is necessary to attend to the condition of

man; it is then that man, undeceived as to the things of this life,

acknowledges his errors. But there is, perhaps, no idea in the whole

circle of theology more unreasonable than this, of which the

credulous, in all ages, have been the dupes. Is it not at the time of

a man's dissolution that he is the least capable of judging of his

true interest? His bodily frame racked, it may be, with pain, his mind

is necessarily weakened or chafed; or if he should be free from

excruciating pain, the lassitude and yielding of nature to the

irrevocable decrees of fate at death, unfit a man for reasoning and

judging of the sophisms that are proposed as panaceas for all his

errors. There are, without doubt, as strange notions as those of

religion; but who knows that body and soul sink alike at death?

It is in the case of health that we can promise ourselves to reason

with justness; it is then that the soul, neither troubled by fear, nor

altered by disease, nor led astray by passion, can judge soundly of

what is beneficial to man. The judgments of the dying can have no

weight with men in good health; and they are the veriest impostors who

lend them belief. The truth can alone be known, when both body and

mind are in good health. No man, without evincing an insensible and

ridiculous presumption, can answer for the ideas he is occupied with,

when worn out with sickness and disease; yet have the inhuman priests

the effrontery to persuade the credulous to take as their examples the

words and actions of men necessarily deranged in intellect by the

derangement of their corporeal frame. In short, since the ideas of men

necessarily vary with the different variations of their bodies, the

man who presumes to reason on his death bed with the man in health,

arrogates what ought not to be conceded.
