Perhaps an illustration will make my meaning clearer: when one of those audacious poets affirms that there was once a three-headed and six-handed man, if you accept that quietly without questioning its possibility, he will proceed to fill in the picture consistently—six eyes and ears, three voices talking at once, three mouths eating, and thirty fingers instead of our poor ten all told; if he has to fight, three of his hands will have a buckler, wicker targe, or shield apiece, while of the other three one swings an axe, another hurls a spear, and the third wields a sword. It is too late to carp at these details, when they come; they are consistent with the beginning; it was about that that the question ought to have been raised whether it was to be accepted and passed as true. Once grant that, and the rest comes flooding in, irresistible, hardly now susceptible of doubt, because it is consistent and accordant with your initial admissions. That is just your case; your love-yearning would not allow you to look into the facts at each entrance, and so you are dragged on by consistency; it never occurs to you that a thing may be self- consistent and yet false; if a man says twice five is seven, and you take his word for it without checking the sum, he will naturally deduce that four times five is fourteen, and so on ad libitum. This is the way that weird geometry proceeds: it sets before beginners certain strange assumptions, and insists on their granting the existence of inconceivable things, such as points having no parts, lines without breadth, and so on, builds on these rotten foundations a superstructure equally rotten, and pretends to go on to a demonstration which is true, though it starts from premisses which are false.
Just so you, when you have granted the principles of any school, believe in the deductions from them, and take their consistency, false as it is, for a guarantee of truth. Then with some of you, hope travels through, and you die before you have seen the truth and detected your deceivers, while the rest, disillusioned too late, will not turn back for shame: what, confess at their years that they have been abused with toys all this time? so they hold on desperately, putting the best face upon it and making all the converts they can, to have the consolation of good company in their deception; they are well aware that to speak out is to sacrifice the respect and superiority and honour they are accustomed to; so they will not do it if it may be helped, knowing the height from which they will fall to the common level. Just a few are found with the courage to say they were deluded, and warn other aspirants. Meeting such a one, call him a good man, a true and an honest; nay, call him philosopher, if you will; to my mind, the name is his or no one's; the rest either have no knowledge of the truth, though they think they have, or else have knowledge and hide it, shamefaced cowards clinging to reputation.
But now for goodness' sake let us drop all this, cover it up with an amnesty, and let it be as if it had not been said; let us, assume that the Stoic philosophy, and no other, is correct; then we can examine whether it is practicable and possible, or its disciples wasting their pains; it makes wonderful promises, I am told, about the Happiness in store for those who reach the summit; for none but they shall enter into full possession of the true Good. The next point you must help me with— whether you have ever met such a Stoic, such a pattern of Stoicism, as to be unconscious of pain, untempted by pleasure, free from wrath, superior to envy, contemptuous of wealth, and, in one word, Happy; such should the example and model of the Virtuous life be; for any one who falls short in the slightest degree, even though he is better than other men at all points, is not complete, and in that case not yet Happy.
Her. I never saw such a man.
Ly. I am glad you do not palter with the truth. But what are your hopes in pursuing philosophy, then? You see that neither your own teacher, nor his, nor his again, and so on to the tenth generation, has been absolutely wise and so attained Happiness. It will not serve you to say that it is enough to get near Happiness; that is no good; a person on the doorstep is just as much outside and in the air as another a long way off, though with the difference that the former is tantalized by a nearer view. So it is to get into the neighbourhood of Happiness—I will grant you so much—that you toil like this, wearing yourself away, letting this great portion of your life slip from you, while you are sunk in dullness and wakeful weariness; and you are to go on with it for twenty more years at the least, you tell me, to take your place when you are eighty—always assuming some one to assure you that length of days—in the ranks of the not yet Happy. Or perhaps you reckon on being the exception; you are to crown your pursuit by attaining what many a good man before you, swifter far, has pursued and never overtaken.
Well, overtake it, if that is your plan, grasp it and have it whole, this something, mysterious to me, of which the possession is sufficient reward for such toils; this something which I wonder how long you will have the enjoyment of, old man that you will be, past all pleasure, with one foot in the grave; ah, but perhaps, like a brave soul, you are getting ready for another life, that you may spend it the better when you come to it, having learned how to live: as though one should take so long preparing and elaborating a superlative dinner that he fainted with hunger and exhaustion!
However, there is another thing I do not think you have observed: Virtue is manifested, of course, in action, in doing what is just and wise and manly; but you—and when I say you, I mean the most advanced philosophers—you do not seek these things and ensue them, but spend the greater part of your life conning over miserable sentences and demonstrations and problems; it is the man who does best at these that you hail a glorious victor. And I believe that is why you admire this experienced old professor of yours: he nonplusses his associates, knows how to put crafty questions and inveigle you into pitfalls; so you pay no attention to the fruit—which consists in action—, but are extremely busy with the husks, and smother each other with the leaves in your debates; come now, Hermotimus, what else are you about from morning to night?
Her. Nothing; that is what it comes to.
Ly. Is it wronging you to say that you hunt the shadow or the snake's dead slough, and neglect the solid body or the creeping thing itself? You are no better than a man pouring water into a mortar and braying it with an iron pestle; he thinks he is doing a necessary useful job, whereas, let him bray till all's blue (excuse the slang), the water is as much water as ever it was.
And here let me ask you whether, putting aside his discourse, you would choose to resemble your master, and be as passionate, as sordid, as quarrelsome, ay, and as addicted to pleasure (though that trait of his is not generally known). Why no answer, Hermotimus? Shall I tell you a plea for philosophy which I lately heard? It was from the mouth of an old, old man, who has quite a company of young disciples. He was angrily demanding his fees from one of these; they were long overdue, he said; the day stated in the agreement was the first of the month, and it was now the fifteenth.
