Mark Twain’s What Is Man? and Other Essays is a collection of philosophical dialogues that probe the nature of human agency. The opening passage presents a conversation between two interlocutors, Y.M. and O.M., who dissect the idea that people are nothing more than machines governed by external forces. Through a series of analogies, comparing iron ore to steel, and men to “gold men, tin men, copper men”, the text argues that personal merit is an illusion, that thoughts and actions arise solely from inherited make and outside influences. The exchange is dense with rhetorical questions and relentless clarification, setting a tone of systematic inquiry rather than narrative storytelling.
Twain’s voice here is unmistakably his late‑19th‑century essayist style: witty, incisive, and laced with a skeptical humor that treats grand ideas as mechanical processes. Readers who relish intellectual debate, enjoy probing the limits of free will, or appreciate a satirical take on moral philosophy will find this work engaging. Those preferring plot‑driven fiction may find the relentless argumentation demanding, but the essay’s crisp logic and period diction reward a patient, curious mind.

O.M. And it is not a personal demerit in the stone machine that it does so little?
Y.M. Certainly not. It does no more and no less than the law of its make permits and compels it to do. There is nothing personal about it; it cannot choose. In this process of “working up to the matter” is it your idea to work up to the proposition that man and a machine are about the same thing, and that there is no personal merit in the performance of either?
O.M. Yes—but do not be offended; I am meaning no offense. What makes the grand difference between the stone engine and the steel one? Shall we call it training, education? Shall we call the stone engine a savage and the steel one a civilized man? The original rock contained the stuff of which the steel one was built—but along with a lot of sulphur and stone and other obstructing inborn heredities, brought down from the old geologic ages—prejudices, let us call them. Prejudices which nothing within the rock itself had either power to remove or any desire to remove. Will you take note of that phrase?
Y.M. Yes. I have written it down; “Prejudices which nothing within the rock itself had either power to remove or any desire to remove.” Go on.
O.M. Prejudices must be removed by outside influences or not at all. Put that down.
Y.M. Very well; “Must be removed by outside influences or not at all.” Go on.
O.M. The iron’s prejudice against ridding itself of the cumbering rock. To make it more exact, the iron’s absolute indifference as to whether the rock be removed or not. Then comes the outside influence and grinds the rock to powder and sets the ore free. The iron in the ore is still captive. An outside influence smelts it free of the clogging ore. The iron is emancipated iron, now, but indifferent to further progress. An outside influence beguiles it into the Bessemer furnace and refines it into steel of the first quality. It is educated, now—its training is complete. And it has reached its limit. By no possible process can it be educated into gold. Will you set that down?
Y.M. Yes. “Everything has its limit—iron ore cannot be educated into gold.”
O.M. There are gold men, and tin men, and copper men, and leaden men, and steel men, and so on—and each has the limitations of his nature, his heredities, his training, and his environment. You can build engines out of each of these metals, and they will all perform, but you must not require the weak ones to do equal work with the strong ones. In each case, to get the best results, you must free the metal from its obstructing prejudicial ones by education—smelting, refining, and so forth.
Y.M. You have arrived at man, now?
O.M. Yes. Man the machine—man the impersonal engine. Whatsoever a man is, is due to his make, and to the influences brought to bear upon it by his heredities, his habitat, his associations. He is moved, directed, commanded, by exterior influences—_solely_. He originates nothing, not even a thought.
Y.M. Oh, come! Where did I get my opinion that this which you are talking is all foolishness?
O.M. It is a quite natural opinion—indeed an inevitable opinion—but _you _did not create the materials out of which it is formed. They are odds and ends of thoughts, impressions, feelings, gathered unconsciously from a thousand books, a thousand conversations, and from streams of thought and feeling which have flowed down into your heart and brain out of the hearts and brains of centuries of ancestors. Personally you did not create even the smallest microscopic fragment of the materials out of which your opinion is made; and personally you cannot claim even the slender merit of putting the borrowed materials together. That was done _automatically_—by your mental machinery, in strict accordance with the law of that machinery’s construction. And you not only did not make that machinery yourself, but you have not even any command over it.
Y.M. This is too much. You think I could have formed no opinion but that one?
O.M. Spontaneously? No. And you did not form that one; your machinery did it for you—automatically and instantly, without reflection or the need of it.
Y.M. Suppose I had reflected? How then?
O.M. Suppose you try?
Y.M. (After a quarter of an hour.) I have reflected.
O.M. You mean you have tried to change your opinion—as an experiment?
Y.M. Yes.
O.M. With success?
Y.M. No. It remains the same; it is impossible to change it.
O.M. I am sorry, but you see, yourself, that your mind is merely a machine, nothing more. You have no command over it, it has no command over itself—it is worked solely from the outside. That is the law of its make; it is the law of all machines.
Y.M. Can’t I ever change one of these automatic opinions?
O.M. No. You can’t yourself, but exterior influences can do it.
Y.M. And exterior ones only?
O.M. Yes—exterior ones only.
Y.M. That position is untenable—I may say ludicrously untenable.
O.M. What makes you think so?
Y.M. I don’t merely think it, I know it. Suppose I resolve to enter upon a course of thought, and study, and reading, with the deliberate purpose of changing that opinion; and suppose I succeed. _That _is not the work of an exterior impulse, the whole of it is mine and personal; for I originated the project.
O.M. Not a shred of it. It grew out of this talk with me. But for that it would not have occurred to you. No man ever originates anything. All his thoughts, all his impulses, come from the outside.
Y.M. It’s an exasperating subject. The first man had original thoughts, anyway; there was nobody to draw from.
O.M. It is a mistake. Adam’s thoughts came to him from the outside. You have a fear of death. You did not invent that—you got it from outside, from talking and teaching. Adam had no fear of death—none in the world.
Y.M. Yes, he had.
O.M. When he was created?
Y.M. No.
O.M. When, then?
Y.M. When he was threatened with it.
O.M. Then it came from outside. Adam is quite big enough; let us not try to make a god of him. None but gods have ever had a thought which did not come from the outside. Adam probably had a good head, but it was of no sort of use to him until it was filled up from the outside. He was not able to invent the triflingest little thing with it. He had not a shadow of a notion of the difference between good and evil—he had to get the idea from the outside. Neither he nor Eve was able to originate the idea that it was immodest to go naked; the knowledge came in with the apple from the outside. A man’s brain is so constructed that it can originate nothing whatsoever. It can only use material obtained outside. It is merely a machine; and it works automatically, not by will-power. It has no command over itself, its owner has no command over it.
Y.M. Well, never mind Adam: but certainly Shakespeare’s creations—
