XX. There remains a topic necessary above all others to this discussion, that of friendship, namely: which you, if pleasure is the chief good, affirm to have no existence at all. Concerning which Epicurus speaks thus: "That of all the things which wisdom has collected to enable man to live happily, nothing is more important, more influential, or more delightful than friendship." Nor did he prove this a.s.sertion by words only, but still more by his life, and conduct, and actions. And how important a thing it is, the fables of the ancients abundantly intimate, in which, many and varied as they are, and traced back to the remotest antiquity, scarcely three pairs of friends are found, even if you begin as far back as Theseus, and come down to Orestes. But in one single house, and that a small one, what great crowds of friends did Epicurus collect, and how strong was the bond of affection that held them together! And this is the case even now among the Epicureans. However, let us return to our subject: it is not necessary for us to be discussing men.
I see, then, that the philosophers of our school have treated the question of friendship in three ways. Some, as they denied that those pleasures which concerned our friends were to be sought with as much eagerness for their own sake, as we display in seeking our own, (by pressing which topic some people think that the stability of friendship is endangered,) maintain that doctrine resolutely, and, as I think, easily explain it.
For, as in the case of the virtues which I have already mentioned, so too they deny that friendship can ever be separated from pleasure. For, as a life which is solitary and dest.i.tute of friends is full of treachery and alarm, reason itself warns us to form friendships. And when such are formed, then our minds are strengthened, and cannot be drawn away from the hope of attaining pleasure. And as hatred, envy, and contempt are all opposed to pleasures, so friendships are not only the most faithful favourers, but also are the efficient causes of pleasures to one"s friends as well as to oneself; and men not only enjoy those pleasures at the moment, but are also roused by hopes of subsequent and future time. And as we cannot possibly maintain a lasting and continued happiness of life without friendship, nor maintain friendship itself unless we love our friends and ourselves equally, therefore this very effect is produced in friendship, and friendship is combined with pleasure.
For we rejoice in the joy of our friends as much as we do in our own, and we are equally grieved at their sorrows. Wherefore the wise man will feel towards his friend as he does towards himself, and whatever labour he would encounter with a view to his own pleasure, he will encounter also for the sake of that of his friend. And all that has been said of the virtues as to the way in which they are invariably combined with pleasure, should also be said of friendship. For admirably does Epicurus say, in almost these exact words: "The same science has strengthened the mind so that it should not fear any eternal or long lasting evil, inasmuch as in this very period of human life, it has clearly seen that the surest bulwark against evil is that of friendship."
There are, however, some Epicureans who are rather intimidated by the reproaches of your school, but still men of sufficient acuteness, and they are afraid lest, if we think that friendship is only to be sought after with a view to our own pleasure, all friendships should, as it were, appear to be crippled. Therefore they admit that the first meetings, and unions, and desires to establish intimacy, do arise from a desire of pleasure; but, they say, that when progressive habit has engendered familiarity, then such great affection is ripened, that friends are loved by one another for their own sake, even without any idea of advantage intermingling with such love. In truth, if we are in the habit of feeling affection for places, and temples, and cities, and gymnasia, and the Campus Martius, and for dogs, and horses, and sports, in consequence of our habit of exercising ourselves, and hunting, and so on, how much more easily and reasonably may such a feeling be produced in us by our intimacy with men!
But some people say that there is a sort of agreement entered into by wise men not to love their friends less than themselves; which we both imagine to be possible, and indeed see to be often the case; and it is evident that nothing can be found having any influence on living agreeably, which is better suited to it than such a union. From all which considerations it may be inferred, not only that the principle of friendship is not hindered by our placing the chief good in pleasure, but that without such a principle it is quite impossible that any friendship should be established.
XXI. Wherefore, if the things which I have been saying are clearer and plainer than the sun itself; if all that I have said is derived from the fountain of nature; if the whole of my discourse forces a.s.sent to itself by its accordance with the senses, that is to say, with the most incorruptible and honest of all witnesses; if infant children, and even brute beasts, declare almost in words, under the teaching and guidance of nature, that nothing is prosperous but pleasure, nothing hateful but pain-a matter as to which their decision is neither erroneous nor corrupt-ought we not to feel the greatest grat.i.tude to that man who, having heard this voice of nature, as I may call it, has embraced it with such firmness and steadiness, that he has led all sensible men into the path of a peaceful, tranquil, and happy life? And as for his appearing to you to be a man of but little learning, the reason of that is, that he thought no learning deserving of the name except such as a.s.sisted in the attainment of a happy life. Was he a man to waste his time in reading poets, as Triarius and I do at your instigation? men in whose works there is no solid utility, but only a childish sort of amus.e.m.e.nt; or to devote himself, like Plato, to music, geometry, arithmetic, and astronomy?
studies which, starting from erroneous principles, cannot possibly be true; and which, if they were true, would const.i.tute nothing to our living more agreeably, that is to say, better. Should he, then, pursue such occupations as those, and abandon the task of laying down principles of living, laborious, but, at the same time, useful as they are?
Epicurus, then, was not dest.i.tute of learning; but those persons are ignorant who think that those studies which it is discreditable for boys not to have learnt, are to be continued till old age.
And when he had spoken thus,-I have now, said he, explained my opinions, and have done so with the design of learning your judgment of them. But the opportunity of doing so, as I wished, has never been offered me before to-day.
Second Book Of The Treatise On The Chief Good And Evil.
I. On this, when both of them fixed their eyes on me, and showed that they were ready to listen to me:-In the first place, said I, I intreat you not to fancy that I, like a professed philosopher, am going to explain to you the doctrines of some particular school; a course which I have never much approved of when adopted by philosophers themselves. For when did Socrates, who may fairly be called the parent of philosophy, ever do anything of the sort? That custom was patronized by those who at that time were called Sophists, of which number Georgias of Leontium was the first who ventured in an a.s.sembly to demand a question,-that is to say, to desire any one in the company to say what he wished to hear discussed. It was a bold proceeding; I should call it an impudent one, if this fashion had not subsequently been borrowed by our own philosophers. But we see that he whom I have just mentioned, and all the other Sophists, (as may be gathered from Plato,) were all turned into ridicule by Socrates; for he, by questioning and interrogating them, was in the habit of eliciting the opinions of those with whom he was arguing, and then, if he thought it necessary, of replying to the answers which they had given him. And as that custom had not been preserved by those who came after him, Arcesilaus re-introduced it, and established the custom, that those who wished to become his pupils were not to ask him questions, but themselves to state their opinions; and then, when they had stated them, he replied to what they had advanced; but those who came to him for instruction defended their own opinions as well as they could.
But with all the rest of the philosophers the man who asks the question says no more; and this practice prevails in the Academy to this day. For when he who wishes to receive instruction has spoken thus, "Pleasure appears to me to be the chief good," they argue against this proposition in an uninterrupted discourse; so that it may be easily understood that they who say that they entertain such and such an opinion, do not of necessity really entertain it, but wish to hear the arguments which may be brought against it. We follow a more convenient method, for not only has Torquatus explained what his opinions are, but also why he entertains them: but I myself think, although I was exceedingly delighted with his uninterrupted discourse, that still, when you stop at each point that arises, and come to an understanding what each party grants, and what he denies, you draw the conclusion you desire from what is admitted with more convenience, and come to an end of the discussion more readily. For when a discourse is borne on uninterruptedly, like a torrent, although it hurries along in its course many things of every kind, you still can take hold of nothing, and put your hand on nothing, and can find no means of restraining that rapid discourse.
II. But every discourse which is concerned in the investigation of any matter, and which proceeds on any system and principle, ought first to establish the rule (as is done in lawsuits, where one proceeds according to set formulas), in order that it may be agreed between the parties to the discussion, what the subject of the discussion really is. This rule was approved by Epicurus, as it was laid down by Plato in his "Phaedrus,"
and he considered that it ought to be adopted in every controversy. But he did not perceive what was the necessary consequence of it, for he a.s.serts that the subject ought not to be defined; but if this be not done, it is sometimes impossible that the disputants should agree what the matter is that is the subject of discussion, as in this very case which we are discussing now, for we are inquiring into the End of Good. How can we know what the character of this is, if, when we have used the expression the End of Good, we do not compare with one another our ideas of what is meant by the End, and of what the Good itself is?
And this laying open of things covered up, as it were, when it is once explained what each thing is, is the definition of it; which you sometimes used without being aware of it; for you defined this very thing, whether it is to be called the End, or the extremity, or the limit, to be that to which everything which was done rightly was referred, and which was itself never referred to anything. So far was very well said; and, perhaps, if it had been necessary, you would also have defined the Good itself, and told us what that was; making it to be that which is desirable by nature, or that which is profitable, or that which is useful, or that which is pleasant: and now, since you have no general objections to giving definitions, and do it when you please, if it is not too much trouble, I should be glad if you would define what is pleasure, for that is what all this discussion relates to.
As if, said he, there were any one who is ignorant what pleasure is, or who is in need of any definition to enable him to understand it better.
I should say, I replied, that I myself am such a man, if I did not seem to myself to have a thorough acquaintance with, and an accurate idea and notion of, pleasure firmly implanted in my mind. But, at present, I say that Epicurus himself does not know, and that he is greatly in error on this subject; and that he who mentions the subject so often ought to explain carefully what the meaning of the words he uses is, but that he sometimes does not understand what the meaning of this word pleasure is, that is to say, what the idea is which is contained under this word.
III. Then he laughed, and said,-This is a capital idea, indeed, that he who says that pleasure is the end of all things which are to be desired, the very extreme point and limit of Good, should be ignorant of what it is, and of what is its character. But, I replied, either Epicurus is ignorant of what pleasure is, or else all the rest of the world are. How so? said he.
Because all men feel that this is pleasure which moves the senses when they receive it, and which has a certain agreeableness pervading it throughout. What then, said he, is Epicurus ignorant of that kind of pleasure? Not always, I replied; for sometimes he is even too well acquainted with it, inasmuch as he declares that he is unable even to understand where it is, or what any good is, except that which is enjoyed by the instrumentality of meat or drink, or the pleasure of the ears, or sensual enjoyment: is not this what he says? As if, said he, I were ashamed of these things, or as if I were unable to explain in what sense these things are said. I do not doubt, I replied, that you can do so easily; nor is there any reason why you need be ashamed of arguing with a wise man, who is the only man, as far as I know, who has ever ventured to profess himself a wise man. For they do not think that Metrodorus himself professed this, but only that, when he was called wise by Epicurus, he was unwilling to reject such an expression of his goodwill. But the Seven had this name given to them, not by themselves, but by the universal suffrage of all nations. However, in this place, I will a.s.sume that Epicurus, by these expressions, certainly meant to intimate the same kind of pleasure that the rest do; for all men call that pleasing motion by which the senses are rendered cheerful, ?d??? in Greek, and _voluptas_ in Latin.
What is it, then, that you ask? I will tell you, said I, and that for the sake of learning rather than of finding fault with either you or Epicurus.
I too, said he, should be more desirous to learn of you, if you can impart anything worth learning, than to find fault with you.
Well, then, said I, you are aware of what Hieronymus(25) of Rhodes says is the chief good, to which he thinks that everything ought to be referred? I know, said he, that he thinks that the great end is freedom from pain.
Well, what are his sentiments respecting pleasure? He affirms, he replied, that it is not to be sought for its own sake; for he thinks that rejoicing is one thing, and being free from pain another. And indeed, continued he, he is in this point greatly mistaken, for, as I proved a little while ago, the end of increasing pleasure is the removal of all pain. I will examine, said I, presently, what the meaning of the expression, freedom from pain, is; but unless you are very obstinate, you must admit that pleasure is a perfectly distinct thing from mere freedom from pain. You will, however, said he, find that I am obstinate in this; for nothing can be more real than the ident.i.ty between the two. Is there, now, said I, any pleasure felt by a thirsty man in drinking? Who can deny it? said he. Is it, asked I, the same pleasure that he feels after his thirst is extinguished? It is, replied he, another kind of pleasure; for the state of extinguished thirst has in it a certain stability of pleasure, but the pleasure of extinguishing it is pleasure in motion. Why, then, said I, do you call things so unlike one another by the same name? Do not you recollect, he rejoined, what I said just now,-that when all pain is banished, pleasure is varied, not extinguished? I recollect, said I; but you spoke in admirable Latin, indeed, but yet not very intelligibly; for _varietas_ is a Latin word, and properly applicable to a difference of colour, but it is applied metaphorically to many differences: we apply the adjective, _varias_, to poems, orations, manners, and changes of fortune; it is occasionally predicated also of pleasure, when it is derived from many things unlike one another, which cause pleasures which are similarly unlike. Now, if that is the variety you mean, I should understand you, as, in fact, I do understand you, without your saying so: but still, I do not see clearly what that variety is, because you say, that when we are free from pain we are then in the enjoyment of the greatest pleasure; but when we are eating those things which cause a pleasing motion to the senses, then there is a pleasure in the emotion which causes a variety in the pleasure; but still, that that pleasure which arises from the freedom from pain is not increased;-and why you call that pleasure I do not know.
IV. Is it possible, said he, for anything to be more delightful than freedom from pain? Well, said I, but grant that nothing is preferable to that, (for that is not the point which I am inquiring about at present,) does it follow on that account, that pleasure is identical with what I may call painlessness? Undoubtedly it is identical with it, said he; and that painlessness is the greatest of pleasures which no other can possibly exceed. Why, then, said I, do you hesitate, after you have defined the chief good in this manner, to uphold, and defend, and maintain the proposition, that the whole of pleasure consists in freedom from pain? For what necessity for your introducing pleasure among the council of the virtues, any more than for bringing in a courtezan to an a.s.sembly of matrons? The very name of pleasure is odious, infamous, and a just object of suspicion: therefore, you are all in the constant habit of saying that we do not understand what Epicurus means when he speaks of pleasure. And whenever such an a.s.sertion is made to me,-and I hear it advanced pretty often,-although I am usually a very peaceful arguer, still I do on such occasions get a little angry. Am I to be told that I do not know what that is which the Greeks call ?d???, and the Latins _voluptas_? Which language is it, then, that I do not understand? Then, too, how comes it about that I do not understand, though every one else does, who chooses to call himself an Epicurean? when the disciples of your school argue most excellently, that there is no need whatever for a man, who wishes to become a philosopher, to be acquainted with literature. Therefore, just as our ancestors tore Cincinnatus away from his plough to make him Dictator, in like manner you collect from among the Greeks all those men, who may in truth be respectable men enough, but who are certainly not over-learned.
Do they then understand what Epicurus means, and do I not understand it?
However, that you may know that I do understand, first of all I tell you that _voluptas_ is the same thing that he calls ?d???. And, indeed, we often have to seek for a Latin word equivalent to, and exactly equipollent to a Greek one; but here we had nothing to seek for: for no word can be found which will more exactly express in Latin what ?d??? does in Greek, than _voluptas_. Now every man in the world who understands Latin, comprehends under this word two things,-joy in the mind, and an agreeable emotion of pleasantness in the body. For when the man in Trabea(26) calls an excessive pleasure of the mind joy, (_laet.i.tia_,) he says much the same as the other character in Caecilius"s play, who says that he is joyful with every sort of joy.
However, there is this difference, that pleasure is also spoken of as affecting the mind; which is wrong, as the Stoics think, who define it thus: "An elation of the mind without reason, when the mind has an idea that it is enjoying some great good." But the words _laet.i.tia_ (gladness), and _gaudium_ (joy), do not properly apply to the body. But the word _voluptas_ (pleasure) is applied to the body by the usage of all people who speak Latin, whenever that pleasantness is felt which moves any one of the senses. Now transfer this pleasantness, if you please, to the mind; for the verb _juvo_ (to please) is applied both to body and mind, and the word _jucundus_ is derived from it; provided you understand that between the man who says,
I am transported with gladness now That I am scarce myself....
and him who says,
Now then at length my mind"s on fire, ...
one of whom is beside himself with joy, and the other is being tormented with anguish, there is this intermediate person, whose language is,
Although this our acquaintance is so new,
who feels neither gladness nor anguish. And, in the same manner, between the man who is in the enjoyment of the pleasures of the body, which he has been wishing for, and him who is being tormented with extreme anguish, there is a third man, who is free alike from pleasure and from pain.
V. Do I not, then, seem to you sufficiently to understand the meaning of words, or must I at this time of life be taught how to speak Greek, and even Latin? And yet I would have you consider, whether if I, who, as I think, understand Greek very fairly, do still not understand what Epicurus means, it it may not be owing to some fault of his for speaking so as not to be intelligible. And this sometimes happens in two ways, without any blame; either if you do so on purpose, as Herac.l.i.tus did, who got the surname of s??te????,(27) because he spoke with too much obscurity about natural philosophy; or when the obscurity of the subject itself, not of the language, prevents what is said from being clearly understood, as is the case in the Timaeus of Plato. But Epicurus, as I imagine, is both willing, if it is in his power, to speak intelligibly, and is also speaking, not of an obscure subject like the natural philosophers, nor of one depending on precise rules, as the mathematicians are, but he is discussing a plain and simple matter, which is a subject of common conversation among the common people. Although you do not deny that we understand the usual meaning of the word _voluptas_, but only what he means by it: from which it follows, not that we do not understand what is the meaning of that word, but that he follows his own fashion, and neglects our usual one; for if he means the same thing that Hieronymus does, who thinks that the chief good is to live without any annoyance, why does he prefer using the term "pleasure" rather than freedom from pain, as Hieronymus does, who is quite aware of the force of the words which he employs? But, if he thinks that he ought to add, that pleasure which consists in motion, (for this is the distinction he draws, that this agreeable pleasure is pleasure in motion, but the pleasure of him who is free from pain is a state of pleasure,) then why does he appear to aim at what is impossible, namely, to make any one who knows himself-that is to say, who has any proper comprehension of his own nature and sensations-think freedom from pain, and pleasure, the same thing?
This, O Torquatus, is doing violence to one"s senses; it is wresting out of our minds the understanding of words with which we are imbued; for who can avoid seeing that these three states exist in the nature of things: first, the state of being in pleasure; secondly, that of being in pain; thirdly, that of being in such a condition as we are at this moment, and you too, I imagine, that is to say, neither in pleasure nor in pain; in such pleasure, I mean, as a man who is at a banquet, or in such pain as a man who is being tortured. What! do you not see a vast mult.i.tude of men who are neither rejoicing nor suffering, but in an intermediate state between these two conditions? No, indeed, said he; I say that all men who are free from pain are in pleasure, and in the greatest pleasure too. Do you, then, say that the man who, not being thirsty himself, mingles some wine for another, and the thirsty man who drinks it when mixed, are both enjoying the same pleasure?
VI. Then, said he, a truce, if you please, to all your questions; and, indeed, I said at the beginning that I would rather have none of them, for I had a provident dread of these captious dialectics. Would you rather, then, said I, that we should argue rhetorically than dialectically? As if, said he, a continuous discourse belonged solely to orators, and not to philosophers also! I will tell you, said I, what Zeno the Stoic said; he said, as Aristotle had said before him, that all speaking was divided into two kinds, and that rhetoric resembled the open palm, dialectics the closed fist, because orators usually spoke in a rather diffuse, and dialecticians in a somewhat compressed style. I will comply, then, with your desires, and will speak, if I can, in an oratorical style, but still with the oratory of the philosophers, and not that which we use in the forum; which is forced at times, when it is speaking so as to suit the mult.i.tude, to submit to a very ordinary style. But while Epicurus, O Torquatus, is expressing his contempt for dialectics, an art which by itself contains the whole science both of perceiving what the real subject is in every question, and also of judging what the character of each thing is, by its system and method of conducting the argument, he goes on too fast, as it seems to me, and does not distinguish with any skill at all the different points which he is intent upon proving, as in this very instance which we were just now speaking of.
Pleasure is p.r.o.nounced to be the chief good. We must then open the question, What is pleasure? for otherwise, the thing which we are seeking for cannot be explained. But, if he had explained it, he would not hesitate; for either he would maintain that same definition of pleasure which Aristippus did, namely, that it is that feeling by which the senses are agreeably and pleasantly moved, which even cattle, if they could speak, would call pleasure; or else, if he chose rather to speak in his own style, than like
All the Greeks from high Mycenae, All Minerva"s Attic youth,
and the rest of the Greeks who are spoken of in these anapaests, then he would call this freedom from pain alone by the name of pleasure, and would despise the definition of Aristippus; or, if he thought both definitions good, as in fact he does, he would combine freedom from pain with pleasure, and would employ the two extremes in his own definition: for many, and they, too, great philosophers, have combined these extremities of goods, as, for instance, Aristotle, who united in his idea the practice of virtue with the prosperity of an entire life. Callipho(28) added pleasure to what is honourable. Diodorus, in his definition, added to the same honourableness, freedom from pain. Epicurus would have done so too, if he had combined the opinion which was held by Hieronymus, with the ancient theory of Aristippus. For those two men disagree with one another, and on this account they employ separate definitions; and, while they both write the most beautiful Greek, still, neither does Aristippus, who calls pleasure the chief good, ever speak of freedom from pain as pleasure; nor does Hieronymus, who lays it down that freedom from pain is the chief good, ever use the word "pleasure" for that painlessness, inasmuch as he never even reckons pleasure at all among the things which are desirable.
VII. They are also two distinct things, that you may not think that the difference consists only in words and names. One is to be without pain, the other to be with pleasure. But your school not only attempt to make one name for these two things which are so exceedingly unlike, (for I would not mind that so much,) but you endeavour also to make one thing out of the two, which is utterly impossible. But Epicurus, who admits both things, ought to use both expressions, and in fact he does divide them in reality, but still he does not distinguish between them in words. For though he in many places praises that very pleasure which we all call by the same name, he ventures to say that he does not even suspect that there is any good whatever unconnected with that kind of pleasure which Aristippus means; and he makes this statement in the very place where his whole discourse is about the chief good. But in another book, in which he utters opinions of the greatest weight in a concise form of words, and in which he is said to have delivered oracles of wisdom, he writes in those words which you are well acquainted with, O Torquatus. For who is there of you who has not learnt the ????a? d??a? of Epicurus, that is to say, his fundamental maxims? because they are sentiments of the greatest gravity intended to guide men to a happy life, and enunciated with suitable brevity. Consider, therefore, whether I am not translating this maxim of his correctly. "If those things which are the efficient causes of pleasures to luxurious men were to release them from all fear of the G.o.ds, and of death, and of pain, and to show them what are the proper limits to their desires, we should have nothing to find fault with; as men would then be filled with pleasures from all quarters, and have on no side anything painful or melancholy, for all such things are evil."
On this Triarius could restrain himself no longer. I beg of you, Torquatus, said he, to tell me, is this what Epicurus says?-because he appeared to me, although he knew it himself, still to wish to hear Torquatus admit it. But he was not at all put out, and said with great confidence, Indeed, he does, and in these identical words; but you do not perceive what he means. If, said I, he says one thing and means another, then I never shall understand what he means, but he speaks plainly enough for me to see what he says. And if what he says is that luxurious men are not to be blamed if they are wise men, he talks absurdly; just as if he were to say that parricides are not to be found fault with if they are not covetous, and if they fear neither G.o.ds, nor death, nor pain. And yet, what is the object of making any exception as to the luxurious, or of supposing any people, who, while living luxuriously, would not be reproved by that consummate philosopher, provided only they guard against all other vices. Still, would not you, Epicurus, blame luxurious men for the mere fact of their living in such a manner as to pursue every sort of pleasure; especially when, as you say, the chief pleasure of all is to be free from pain? But yet we find some debauched men so far from having any religious scruples, that they will eat even out of the sacred vessels; and so far from fearing death that they are constantly repeating that pa.s.sage out of the Hymnis,(29)-
Six months of life for me are quite sufficient, The seventh may be for the shades below,-
and bringing up that Epicurean remedy for pain, as if they were taking it out of a medicine chest: "If it is bitter, it is of short duration; if it lasts a long time, it must be slight in degree." There is one thing which I do not understand, namely, how a man who is devoted to luxury can possibly have his appet.i.tes under restraint.
VIII. What then is the use of saying, I should have nothing to reproach them with if they only set bounds to their appet.i.tes? This is the same as saying, I should not blame debauched men if they were not debauched men.
In the same way one might say, I should not blame even wicked men if they were virtuous. This man of strict morality does not think luxury of itself a thing to be blamed. And, indeed, O Torquatus, to speak the truth, if pleasure is the chief good, he is quite right not to think so. For I should be sorry to picture to myself, (as you are in the habit of doing,) men so debauched as to vomit over the table and be carried away from banquets, and then the next day, while still suffering from indigestion, gorge themselves again; men who, as they say, have never in their lives seen the sun set or rise, and who, having devoured their patrimony, are reduced to indigence. None of us imagine that debauched men of that sort live pleasantly. You, however, rather mean to speak of refined and elegant _bons vivans_, men who, by the employment of the most skilful cooks and bakers, and by carefully culling the choicest products of fishermen, fowlers, and hunters, avoid all indigestion-
