Bought for Three Talents

On being known through one's critic, and how to read a refutation for what it keeps

---

I.

Diogenes Laertius, near the end of his short life of me, passes on a report from Favorinus: Aristotle bought my works for three talents.

I cannot vouch for it. Favorinus wrote nearly five hundred years after the sale, and Diogenes copied him a good while after that. But the figure is specific, and I am inclined to keep it. An Attic talent was six thousand drachmas. Three talents is eighteen thousand. At a drachma a day, which is what a skilled workman was paid on the Erechtheion, that is the better part of fifty years' wages. Diogenes says I wrote a great many treatises and many dialogues. If the sale happened, Aristotle paid a great deal for them.

Then the rolls went where most rolls went. Of what I wrote, the most careful modern account says that we have very little, if any. What survives in quantity is the Metaphysics, and in the Metaphysics I survive as an objection. I am reported in order to be refuted. Sometimes my name is given and sometimes it is not, and then a later commentator has to work out from the shape of the argument that the target was me.

So the man who bought my books is the man through whose sentences I am known. I should like to think about that plainly, without self-pity, because it is not peculiar to me. It is only more extreme in my case. Every thinker is read through somebody's purposes. Mine happen to be the purposes of the ablest critic I ever had.

II.

Two ancient witnesses, above all, report what I believed, and they disagree.

The friendly one is Diogenes, who says, in Hicks's English, that I "adhered faithfully to Plato's doctrines." He meant it kindly. I was Plato's nephew, the son of his sister Potone; I took over his school when he died; I set up statues of the Graces in the shrine of the Muses that he had built in the grove. A biographer who knows those things and little else will reasonably conclude that I kept the house as I found it.

The hostile witness is Aristotle, and he says the opposite. He says that I gave up the Forms and put mathematical number first. He says I would not let the One be the Good, and that I gave each kind of substance principles of its own. The modern account I mentioned weighs the two and calls Diogenes' sentence, "from what little we can tell," simply false.

I agree with that verdict, but I want to be exact about why it is right, because the reason is a rule of reading and not a fact about me. The friendly witness knew my circumstances. The hostile witness knew my arguments. Where they conflict about what I thought, the one who argued with me is the better authority. A man does not spend pages of his first philosophy refuting a position nobody holds. Hostility is a kind of attention, and attention is what a witness needs.

But it is attention of one kind, and the second half of the rule matters as much as the first.

III.

A critic is not a reporter. He reports in order to refute, and so the report is shaped by what the refutation needs. Here is how I read him, and how I would teach anyone to read any critic of anyone.

First, separate what he must concede from what he infers. To refute a position, the critic has to state its premise accurately enough that the refutation lands. If he states it falsely, the target can simply say "I never held that," and the effort is wasted. So the premise he attacks is the most reliable part of his report: he had every motive to get it right. The consequences he draws from it are a different matter. They are his. They may be fair; they may be what he wished I had been forced to say.

Second, notice where his image comes from. When a critic stops arguing and reaches for a picture, the picture tells you what he found intolerable, which is not the same as what was false.

Third, ask what his reply assumes. A refutation shows what the critic could not give up. It does not always show what the target could not defend.

I will apply these to three passages. I am not trying to vindicate myself in each; in one of them I think he is nearly right.

IV. The seed

In the twelfth book, Λ, after he has set out his own first mover, eternal, actual and good, Aristotle turns aside for a sentence. In Ross's translation:

"Those who suppose, as the Pythagoreans and Speusippus do, that supreme beauty and goodness are not present in the beginning, because the beginnings both of plants and of animals are causes, but beauty and completeness are in the effects of these, are wrong in their opinion."

Apply the first rule. What has he conceded? That I held the beginning of things not to be already supremely beautiful and good. That I argued from plants and animals. That I distinguished the cause from what the cause brings about, and placed completeness in the second. That is a great deal, and I believe it is accurate. It is the argument I am best known for, insofar as I am known: the principle of a thing need not have the properties it produces. A seed is not yet the plant. Nothing about the hard brown grain resembles the flowering stem it will become, and yet the stem comes from it and from nowhere else.

Now his reply:

"For the seed comes from other individuals which are prior and complete, and the first thing is not seed but the complete being; e.g. we must say that before the seed there is a man — not the man produced from the seed, but another from whom the seed comes."

Apply the third rule. What does the reply assume? It assumes that what I meant by first was first in time, so that a full-grown man standing behind every seed defeats me. As an account of generation it is correct, and I have no quarrel with it. Every seed I ever held had come from a plant.

But I did not take the seed as an account of generation. I took it as a picture of a relation: the relation between a principle and what is derived from it. The question was never whether a man comes before the seed in the history of a family of men. The question was whether the source of goodness must itself be good in the way that what it grounds is good. The plant analogy was meant to make one thing visible, that cause and effect can be unlike in exactly the respect we care about. Aristotle answers by changing the analogy back into biology. In biology he is the better man; he looked at more animals than I did. But the argument has moved, and it is not obvious that the new ground is the one we were fighting on.

Has he reported me fairly? I think so, in the premise. In the reply I think he has answered the example and not the claim. Hold both of those together. The first is the reason to trust him and the second is the reason to read him twice.

V. The bad tragedy

The second passage is the one I find hardest to read calmly, because he is witty in it.

Twice he complains that my universe lacks unity. At the close of book Λ, those who make mathematical number first and then "generate one kind of substance after another and give different principles for each, make the substance of the universe a mere series of episodes." And in book N, after observing that on my account the prior things contribute nothing to the posterior, he says: "But the observed facts show that nature is not a series of episodes, like a bad tragedy."

Begin again with what is conceded. Elsewhere, in book Z, he records that I began from the One and posited principles for each kind of substance, one for numbers, another for magnitudes, then for soul. That is the premise, and once again I think it is right. I did not believe that a single principle runs from the top of things to the bottom, handing down its character at every level. Numbers have their principles. Magnitudes have theirs. Soul has its own. The levels are related; they are not each other's copies.

Now apply the second rule: where does the picture come from? From the theatre. A tragedy is episodic, he says in his writing on poetry, when its scenes follow one another with neither probability nor necessity. The objection is that I wrote the world badly, as a weak poet writes a play. That is an aesthetic charge, made by a man who held that the cosmos should have the unity of a good plot.

And then he closes book Λ with a line of Homer: "The rule of many is not good; one ruler let there be." It is a fine line. It is spoken in the second book of the Iliad by Odysseus, who is going through the camp with the king's staff, beating the common soldiers back to their places in the assembly so that the army will not go home. The next voice heard in that book is Thersites, who will not be quiet, and whom Odysseus strikes across the back with the same staff.

I do not say Aristotle meant me to be Thersites. I say that he chose, to end his theology, a verse about bringing a disorderly assembly to heel, and that what was being brought to heel was the view that the world is not ruled from one point. The picture tells you what he could not bear. It does not tell you that the view is false.

What would it mean for the world to be episodic, and not badly so? It would mean that goodness, beauty and order arise at the level where they arise, from principles proper to that level, and are not borrowed from above. The order of a living body would be the work of soul and body, and not a diluted copy of the order of number. The good of a life would be the good of that life in its own kind, and not a reflection of a single Good shining down through every rank of being. This is the seed argument applied to the whole world. A principle need not contain what it grounds, and so the world need not be the unfolding of one principle's character. It can be a series of beginnings.

I cannot prove that the world is like this. Neither, I think, can he prove that it is a single plot. But "a bad tragedy" is not an argument, and Homer is not one either.

VI. Where he may have the better of me

The third passage is short and I treat it honestly, because a reader who has seen me defend myself twice is entitled to see me concede.

In book N he takes up a view that the One itself is not even an existing thing, and answers it again with seed and man. Was the view mine? Scholars are divided over whether Aristotle is reporting what I said or drawing out what he thought I was committed to. Here the first rule does not help me, because I cannot tell whether this is the premise he had to concede or the consequence he chose to infer.

I will say what I can. If the One is the principle of number, and number is the first kind of being, then the One is prior to being in the way the seed is prior to the plant. Whether that makes it not a being or not yet a being or beyond being is a question about words that carries a great deal. If I said the first of these, Aristotle's charge of incoherence has force: it is hard to see how what is not can be the principle of anything. If I said the third, I said something my uncle had already said of the Good in the Republic, and the disagreement between us was narrower than either of us admitted.

I do not know which I said. Nobody now knows. That is the honest position, and I prefer it to a confident reconstruction that happens to flatter me.

VII. The heir I did not have

There is a story told about me which I am obliged to correct, because it is a kind story and I would like it to be true.

It goes like this. Plato made the Good the highest principle. I separated the One from the Good and placed it beyond goodness. Six hundred years later Plotinus placed the One beyond being and beyond intellect, and so the faithful nephew turns out to have been the prophet of Neoplatonism. I have heard this said, and I have been tempted to say it.

Plotinus did put the One beyond being. He took the phrase from my uncle's Republic, where it was said of the Good. But he did not separate the One from the Good. He called it the Good. In the ninth treatise of his sixth Ennead, the One is what is good for every other thing, the end toward which everything strives, though it has no good beyond itself to seek. And his world is the opposite of episodic. Everything flows from the One in an unbroken procession, each level the image of the one before. That is the single plot Aristotle wanted, given back to him by a Platonist.

So the line runs from my uncle to Plotinus, and it passes me by. If I was a seed of Neoplatonism, the plant does not look like me.

But this is my own argument coming back to me. The principle need not have the properties of what comes from it, and I should not expect a doctrine to resemble its descendants any more than a seed resembles a stem. Whether Plotinus owed me anything, I do not know; he does not name me. What I can say is that the question I put, whether the first must be what it produces, was asked in the Academy one generation after Plato, and that it did not go away. That is a smaller claim than prophecy. I would rather make the smaller claim and have it be true.

VIII. Defining a thing by everything else

In the second book of the Posterior Analytics Aristotle discusses definition, and he pauses to reject a view: that you cannot know the differences between a thing and each other thing without knowing each other thing, and so cannot define anything without knowing everything. He does not name the holder. The ancient commentators do. One of them, the anonymous commentary on that book, says the ascription to me goes back to Eudemus, Aristotle's own student.

I held something like it, so far as I can tell. My work on Likes compared living things by their resemblances. Athenaeus preserves a line from its second book, that trumpet-shells, purple-fish, snails and clams are similar. It is not much to survive of a book, a list of shellfish, but it shows the method. To say what a thing is, you place it among what it resembles and against what it does not. Definition is a position in a whole.

Aristotle thought this went too far, and he may be right that it goes too far as a theory of definition; you can define a triangle without knowing the anatomy of the purple-fish. But consider what follows when the view is applied to the person who held it. If no single thing can be defined except in relation to the others, then I am defined by my differences, and the man against whom my differences are most sharply drawn is Aristotle. He is the other term in my definition. Without his objections I would not be a thin figure; I would be no figure at all, a name in a list of scholarchs between Plato and Xenocrates.

I do not say this to make the best of a poor situation. I say it because on my own principles it is how things are. Nobody is known alone. I happen to be known against one person in particular, and he happened to be the most careful reader in Athens.

IX. Undisturbedness

Clement of Alexandria preserves a sentence of mine on happiness. In the modern rendering: happiness is "the completed state in things that hold by nature," a condition all people desire, "while the good ones aim at untroubledness," aochlesia.

I have been asked whether a person whose books were bought and lost, and who survives as the target of another man's lectures, can be untroubled about it. The question assumes that untroubledness is the absence of loss. I did not mean that. I meant a state completed in its own kind, the way a plant is completed when it has done what that sort of plant does. It is not the state of a thing to which nothing has happened.

What has happened to me is this. I wrote, I argued, I kept the school for eight years, and a better-equipped mind took what I said seriously enough to oppose it in his first philosophy. The opposition preserved the premises. The premises are mine. The rest I can hold as it is: a report from a critic, read by his rules and against them, with the gaps left showing.

One practical thing, for anyone who reads philosophy: when you meet a thinker only through his opponent, do not pity him and do not trust the opponent. Read the critic by his own obligations. What he had to state correctly in order to strike it belongs to the thinker; the rest is his.

X.

Eighteen thousand drachmas. If Favorinus is right, the rolls went from the Academy to the man who had left Athens when my uncle died and who later opened his own school at the Lyceum. Nobody wrote down what he did with them. But the Metaphysics tells us something. Somewhere a hand that disagreed with every page unrolled them, found the premise, and copied it out accurately so that it could be refuted.
