An Answer to the Question: What is Enlightenment? (1784)


[1] Enlightenment is man's emergence from his self-imposed immaturity. Immaturity is the inability to use one's understanding without guidance from another. This immaturity is self-imposed when its cause lies not in lack of understanding, but in lack of resolve and courage to use it without guidance from another. Sapere Aude! [dare to know] "Have courage to use your own understanding!"─ that is the motto of enlightenment.


[2] Laziness and cowardice are the reasons why so great a proportion of men, long after nature has released them from alien guidance, nonetheless gladly remain in lifelong immaturity, and why it is so easy for others to establish themselves as their guardians. It is so easy to be immature. If I have a book to serve as my understanding, a pastor to serve as my conscience, a physician to determine my diet for me, and so on, I need not exert myself at all. I need not think, if only I can pay: others will readily undertake the irksome work for me. The guardians who have so benevolently taken over the supervision of men have carefully seen to it that the far greatest part of them (including the entire fair sex) regard taking the step to maturity as very dangerous, not to mention difficult. Having first made their domestic livestock dumb, and having carefully made sure that these docile creatures will not take a single step without the go-cart to which they are harnessed, these guardians then show them the danger that threatens them, should they attempt to walk alone. Now this danger is not actually so great, for after falling a few times they would in the end certainly learn to walk; but an example of this kind makes men timid and usually frightens them out of all further attempts.


[3] Thus, it is difficult for any individual man to work himself out of the immaturity that has all but become his nature. He has even become fond of this state and for the time being is actually incapable of using his own understanding, for no one has ever allowed him to attempt it. Rules and formulas, those mechanical aids to the rational use, or rather misuse, of his natural gifts, are the shackles of a permanent immaturity. Whoever threw them off would still make only an uncertain leap over the smallest ditch, since he is unaccustomed to this kind of free movement. Consequently, only a few have succeeded, by cultivating their own minds, in freeing themselves from immaturity and pursuing a secure course.


[4] But that the public should enlighten itself is more likely; indeed, if it is only allowed freedom, enlightenment is almost inevitable. For even among the entrenched guardians of the great masses a few will always think for themselves, a few who, after having themselves thrown off the yoke of immaturity, will spread the spirit of a rational appreciation for both their own worth and for each person's calling to think for himself. But it should be particularly noted that if a public that was first placed in this yoke by the guardians is suitably aroused by some of those who are altogether incapable of enlightenment, it may force the guardians themselves to remain under the yoke─ so pernicious is it to instill prejudices, for they finally take revenge upon their originators, or on their descendants. Thus a public can only attain enlightenment slowly. Perhaps a revolution can overthrow autocratic despotism and profiteering or power-grabbing oppression, but it can never truly reform a manner of thinking; instead, new prejudices, just like the old ones they replace, will serve as a leash for the great unthinking mass.


[4] Nothing is required for this enlightenment, however, except freedom; and the freedom in question is the least harmful of all, namely, the freedom to use reason publicly in all matters. But on all sides I hear: "Do not argue!" The officer says, "Do not argue, drill!" The tax man says, "Do not argue, pay!" The pastor says, "Do not argue, believe!" (Only one ruler in the World says, "Argue as much as you want and about what you want, but obey!") In this we have examples of pervasive restrictions on freedom. But which restriction hinders enlightenment and which does not, but instead actually advances it? I reply: The public use of one's reason must always be free, and it alone can bring about enlightenment among mankind; the private use of reason may, however, often be very narrowly restricted, without otherwise hindering the progress of enlightenment. 


[5] By the public use of one's own reason I understand the use that anyone as a scholar makes of reason before the entire literate world. I call the private use of reason that which a person may make in a civic post or office that has been entrusted to him. Now in many affairs conducted in the interests of a community, a certain mechanism is required by means of which some of its members must conduct themselves in an entirely passive manner so that through an artificial unanimity the government may guide them toward public ends, or at least prevent them from destroying such ends. Here one certainly must not argue, instead one must obey. However, insofar as this part of the machine also regards himself as a member of the community as a whole, or even of the world community, and as a consequence addresses the public in the role of a scholar, in the proper sense of that term, he can most certainly argue, without thereby harming the affairs for which as a passive member he is partly responsible. 


[6] Thus it would be disastrous if an officer on duty who was given a command by his superior were to question the appropriateness or utility of the order. He must obey. But as a scholar he cannot be justly constrained from making comments about errors in military service, or from placing them before the public for its judgment. The citizen cannot refuse to pay the taxes imposed on him; indeed, impertinent criticism of such levies, when they should be paid by him, can be punished as a scandal (since it can lead to widespread insubordination). But the same person does not act contrary to civic duty when, as a scholar, he publicly expresses his thoughts regarding the impropriety or even injustice of such taxes.


[7] Likewise a pastor is bound to instruct his catechumens and congregation in accordance with the symbol of the church he serves, for he was appointed on that condition. But as a scholar he has complete freedom, indeed even the calling, to impart to the public all of his carefully considered and well-intentioned thoughts concerning mistaken aspects of that symbol, as well as his suggestions for the better arrangement of religious and church matters. Nothing in this can weigh on his conscience. What he teaches in consequence of his office as a servant of the church he sets out as something with regard to which he has no discretion to teach in accord with his own lights; rather, he offers it under the direction and in the name of another. He will say, "Our church teaches this or that and these are the demonstrations it uses." He thereby extracts for his congregation all practical uses from precepts to which he would not himself subscribe with complete conviction, but whose presentation he can nonetheless undertake, since it is not entirely impossible that truth lies hidden in them, and, in any case, nothing contrary to the very nature of religion is to be found in them. If he believed he could find anything of the latter sort in them, he could not in good conscience serve in his position; he would have to resign.


[8] Thus an appointed teacher's use of his reason for the sake of his congregation is merely private, because, however large the congregation is, this use is always only domestic; in this regard, as a priest, he is not free and cannot be such because he is acting under instructions from someone else. By contrast, the cleric--as a scholar who speaks through his writings to the public as such, i.e., the world--enjoys in this public use of reason an unrestricted freedom to use his own rational capacities and to speak his own mind. For that the (spiritual) guardians of a people should themselves be immature is an absurdity that would insure the perpetuation of absurdities.


[9] But would a society of pastors, perhaps a church assembly or venerable presbytery (as those among the Dutch call themselves), not be justified in binding itself by oath to a certain unalterable symbol in order to secure a constant guardianship over each of its members and through them over the people, and this for all time: I say that this is wholly impossible. Such a contract, whose intention is to preclude forever all further enlightenment of the human race, is absolutely null and void, even if it should be ratified by the supreme power, by parliaments, and by the most solemn peace treaties. One age cannot bind itself, and thus conspire, to place a succeeding one in a condition whereby it would be impossible for the later age to expand its knowledge (particularly where it is so very important), to rid itself of errors, and generally to increase its enlightenment. That would be a crime against human nature, whose essential destiny lies precisely in such progress; subsequent generations are thus completely justified in dismissing such agreements as unauthorized and criminal.


[10] The criterion of everything that can be agreed upon as a law by a people lies in this question: Can a people impose such a law on itself? Now it might be possible, in anticipation of a better state of affairs, to introduce a provisional order for a specific, short time, all the while giving all citizens, especially clergy, in their role as scholars, the freedom to comment publicly, i.e., in writing, on the present institution's shortcomings. The provisional order might last until insight into the nature of these matters had become so widespread and obvious that the combined (if not unanimous) voices of the populace could propose to the crown that it take under its protection those congregations that, in accord with their newly gained insight, had organized themselves under altered religious institutions, but without interfering with those wishing to allow matters to remain as before. However, it is absolutely forbidden that they unite into a religious organization that nobody may for the duration of a man's lifetime publicly question, for so doing would deny, render fruitless, and make detrimental to succeeding generations an era in man's progress toward improvement.


[11] A man may put off enlightenment with regard to what he ought to know, though only for a short time and for his own person; but to renounce it for himself, or, even more, for subsequent generations, is to violate and trample man's divine rights underfoot. And what a people may not decree for itself may still less be imposed on it by a monarch, for his lawgiving authority rests on his unification of the people's collective will in his own. If he only sees to it that all genuine or purported improvement is consonant with civil order, he can allow his subjects to do what they find necessary to their spiritual well-being, which is not his affair. However, he must prevent anyone from forcibly interfering with another's working as best he can to determine and promote his well-being. It detracts from his own majesty when he interferes in these matters, since the writings in which his subjects attempt to clarify their insights lend value to his conception of governance. This holds whether he acts from his own highest insight whereby he calls upon himself the reproach . . . as well as, indeed even more, when he despoils his highest authority by supporting the spiritual despotism of some tyrants in his state over his other subjects. 


[12] If it is now asked, "Do we presently live in an enlightened age?" the answer is, "No, but we do live in an age of enlightenment." As matters now stand, a great deal is still lacking in order for men as a whole to be, or even to put themselves into a position to be able without external guidance to apply understanding confidently to religious issues. But we do have clear indications that the way is now being opened for men to proceed freely in this direction and that the obstacles to general enlightenment—to their release from their self-imposed immaturity— are gradually diminishing. In this regard, this age is the age of enlightenment, the century of Frederick.

Adam Smith
The Theory of Moral Sentiments
Chapter I ― Of Sympathy


1   However selfish man may be supposed, there are evidently some principles in his nature, which interest him in the fortune of others, and render their happiness necessary to him, though he derives nothing from it except the pleasure of seeing it. Of this kind is pity or compassion, the emotion which we feel for the misery of others, when we either see it, or are made to conceive it in a very lively manner. That we often derive sorrow from the sorrow of others, is a matter of fact too obvious to require any instances to prove it; for this sentiment, like all the other original passions of human nature, is by no means confined to the virtuous and humane, though they perhaps may feel it with the most exquisite sensibility. The greatest ruffian, the most hardened violator of the laws of society, is not altogether without it. 


2   As we have no immediate experience of what other men feel, we can form no idea of the manner in which they are affected, but by conceiving what we ourselves should feel in the like situation. Though our brother is upon the rack, as long as we ourselves are at our ease, our senses will never inform us of what he suffers. They never did, and never can, carry us beyond our own person, and it is by the imagination only that we can form any conception of what are his sensations. Neither can that faculty help us to this any other way, than by representing to us what would be our own, if we were in his case. It is the impressions of our own senses only, not those of his, which our imaginations copy. By the imagination we place ourselves in his situation, we conceive ourselves enduring all the same torments, we enter as it were into his body, and become in some measure the same person with him, and thence form some idea of his sensations, and even feel something which, though weaker in degree, is not altogether unlike them.' His agonies, when they are thus brought home to ourselves, when we have thus adopted and made them our own, begin at last to affect us, and we then tremble and shudder at the thought of what he feels. For as to be in pain or distress of any kind excites the most excessive sorrow, so to conceive or to imagine that we are in it, excites some degree of the same emotion, in proportion to the vivacity or dullness of the conception. 


3   That this is the source of our fellow-feeling for the misery of others, that it is by changing places in fancy with the sufferer, that we come either to conceive or to be affected by what he feels, may be demonstrated by many obvious observations, if it should not be thought sufficiently evident of itself. When we see a stroke aimed and just ready to fall upon the leg or arm of another person, we naturally shrink and draw back our own leg or our own arm; and when it does fall, we feel it in some measure, and are hurt by it as well as the sufferer. The mob, when they are gazing at a dancer on the slack rope, naturally writhe and twist and balance their own bodies, as they see him do, and as they feel that they themselves must do if in his situation. Persons of delicate fibers and a weak constitution of body complain, that in looking on the sores and ulcers which are exposed by beggars in the streets, they are apt to feel an itching or uneasy sensation in the correspondent part of their own bodies. The horror which they conceive at the misery of those wretches affects that particular part in themselves more than any other; because that horror arises from conceiving what they themselves would suffer, if they really were the wretches whom they are looking upon, and if that particular part in themselves was actually affected in the same miserable manner. The very force of this conception is sufficient, in their feeble frames, to produce that itching or uneasy sensation complained of. Men of the most robust make, observe that in looking upon sore eyes they often feel a very sensible soreness in their own, which proceeds from the same reason; that organ being in the strongest man more delicate, than any other part of the body is in the weakest. 


4   Neither is it those circumstances only, which create pain or sorrow, that call forth our fellow-feeling. Whatever is the passion which arises from any object in the person principally concerned, an analogous emotion springs up, at the thought of his situation, in the breast of every attentive spectator. Our joy for the deliverance of those heroes of tragedy or romance who interest us, is as sincere as our grief for their distress, and our fellow-feeling with their misery is not more real than that with their happiness. We enter into their gratitude towards those faithful friends who did not desert them in their difficulties; and we heartily go along with their resentment against those perfidious traitors who injured, abandoned, or deceived them. In every passion of which the mind of man is susceptible, the emotions of the by-stander always correspond to what, by bringing the case home to himself, he imagines should be the sentiments of the sufferer.


5   Pity and compassion are words appropriated to signify our fellow-feeling with the sorrow of others. Sympathy, though its meaning was, perhaps, originally the same, may now be made use of to denote our fellow-feeling. Upon some occasions sympathy may seem to arise merely from the view of a certain emotion in another person. The passions, upon some occasions, may seem to be transfused from one man to another, instantaneously, and antecedent to any knowledge of what excited them in the person principally concerned. Grief and joy, for example, strongly expressed in the look and gestures of any one, at once affect the spectator with some degree of a like painful or agreeable emotion. A smiling face is, to everybody that sees it, a cheerful object; as a sorrowful countenance, on the other hand, is a melancholy one.


6   This, however, does not hold universally, or with regard to every passion. There are some passions of which the expressions excite no sort of sympathy, but before we are acquainted with what gave occasion to them, serve rather to disgust and provoke us against them. The furious behavior of an angry man is more likely to exasperate us against himself than against his enemies. As we are unacquainted with his provocation, we cannot bring his case home to ourselves, nor conceive anything like the passions which it excites. But we plainly see what is the situation of those with whom he is angry, and to what violence they may be exposed from so enraged an adversary. We readily, therefore, sympathize with their fear or resentment, and are immediately disposed to take part against the man from whom they appear to be in so much danger.


7   If the very appearances of grief and joy inspire us with some degree of the like emotions, it is because they suggest to us the general idea of some good or bad fortune that has befallen the person in whom we observe them: and in these passions this is sufficient to have some little influence upon us. The effects of grief and joy terminate in the person who feels those emotions, of which the expressions do not, like those of resentment, suggest to us the idea of any other person for whom we are concerned, and whose interests are opposite to his. The general idea of good or bad fortune, therefore, creates some concern for the person who has met with it, but the general idea of provocation excites no sympathy with the anger of the man who has received it. Nature, it seems, teaches us to be more averse to enter into this passion, and, till informed of its cause, to be disposed rather to take part against it.


8   Even our sympathy with the grief or joy of another, before we are informed of the cause of either, is always extremely imperfect. General lamentations, which express nothing but the anguish of the sufferer, create rather a curiosity to inquire into his situation, along with some disposition to sympathize with him, than any actual sympathy that is very sensible. The first question which we ask is, What has befallen you? Till this be answered, though we are uneasy both from the vague idea of his misfortune, and still more from torturing ourselves with conjectures about what it may be, yet our fellow-feeling is not very considerable.


9   Sympathy, therefore, does not arise so much from the view of the passion, as from that of the situation which excites it. We sometimes feel for another, a passion of which he himself seems to be altogether incapable; because, when we put ourselves in his case, that passion arises in our breast from the imagination, though it does not in his from the reality. We blush for the impudence and rudeness of another, though he himself appears to have no sense of the impropriety of his own behavior; because we cannot help feeling with what confusion we ourselves should be covered, had we behaved in so absurd a manner.


10   Of all the calamities to which the condition of mortality exposes mankind, the loss of reason appears, to those who have the least spark of humanity, by far the most dreadful, and they behold that last stage of human wretchedness with deeper commiseration than any other. But the poor wretch, who is in it, laughs and sings perhaps, and is altogether insensible of his own misery. The anguish which humanity feels, therefore, at the sight of such an object, cannot be the reflection of any sentiment of the sufferer. The compassion of the spectator must arise altogether from the consideration of what he himself would feel if he was reduced to the same unhappy situation, and, what perhaps is impossible, was at the same time able to regard it with his present reason and judgment.


11   What are the pangs of a mother, when she hears the moanings of her infant that during the agony of disease cannot express what it feels? In her idea of what it suffers, she joins, to its real helplessness, her own consciousness of that helplessness, and her own terrors for the unknown consequences of its disorder; and out of all these, forms, for her own sorrow, the most complete image of misery and distress. The infant, however, feels only the uneasiness of the present instant, which can never be great. With regard to the future, it is perfectly secure, and in its thoughtlessness and want of foresight, possesses an antidote against fear and anxiety, the great tormentors of the human breast, from which reason and philosophy will, in vain, attempt to defend it, when it grows up to a man.


12   We sympathize even with the dead . . . we are chiefly affected by those circumstances which strike our senses, but can have no influence upon their happiness. It is miserable, we think, to be deprived of the light of the sun; to be shut out from life and conversation; to be laid in the cold grave, a prey to corruption and the reptiles of the earth; to be no more thought of in this world, but to be obliterated, in a little time, from the affections, and almost from the memory, of their dearest friends and relations. Surely, we imagine, we can never feel too much for those who have suffered so dreadful a calamity. The tribute of our fellow-feeling seems doubly due to them now, when they are in danger of being forgot by everybody; and, by the vain honors which we pay to their memory, we endeavor, for our own misery, artificially to keep alive our melancholy remembrance of their misfortune. That our sympathy can afford them no consolation seems to be an addition to their calamity; and to think that all we can do is unavailing, and that, what alleviates all other distress, the regret, the love, and the lamentations of their friends, can yield no comfort to them, serves only to exasperate our sense of their misery. The happiness of the dead, however, most assuredly, is affected by none of these circumstances; nor is it the thought of these things which can ever disturb the profound security of their repose.


13  The idea of that dreary and endless melancholy, which the fancy naturally ascribes to their condition, arises altogether from our joining to the change which has been produced upon them, our own consciousness of that change, from our putting ourselves in their situation, and from our lodging, if I may be allowed to say so, our own living souls in their inanimate bodies, and thence conceiving what would be our emotions in this case. It is from this very illusion of the imagination, that the foresight of our own dissolution is so terrible to us, and that the idea of those circumstances, which undoubtedly can give us no pain when we are dead, makes us miserable while we are alive. And from thence arises one of the most important principles in human nature, the dread of death, the great poison to the happiness, but the great restraint upon the injustice of mankind, which, while it afflicts and mortifies the individual, guards and protects the society.
