At some point — perhaps tonight, perhaps this week — you will set something aside for your future self. It might be a line in a will, a transfer into a retirement account, or simply a figure on a screen that you look at and decide is enough. You are putting away money, or years, or care, for a person who will carry your name and your face and almost none of your present memories: someone you have never met, and might not recognise if you passed them in the street. And you do it without hesitation, because that person is, of course, you — you, later. Of course you provide for your own.
This is Philosophy for Us — philosophy for everyone, no degree required.
This is the eighth episode of The Self Across Time, and it is the last. In the first episode I said the whole series turned on a single question most of us think we have already answered: whether the "you" at the centre of your life is one thing that lasts. And I said that at the far end there would be a harder question waiting — what, if anything, you owe the stranger who will carry your name in thirty years. Tonight we reach that question and hand it back. But it only makes sense on the ground last week laid down, so we should recover last week first.
Last week, for the first time, I brought together two findings from earlier in the series. The first came on the opening night: the memory you would swear to — you and your sister, both certain, each holding a different version of the same afternoon, with no way from the inside to tell whose is accurate — showed that memory is not a recording. There is no faithful tape of who you have been. The second finding took the previous fortnight: we went looking not for the record but for the one who keeps it — a single, continuous owner behind your eyes — and, testing the idea first with a teleporter case, then with an ancient image of a chariot, then by turning attention inward on yourself, we found nothing of the kind. No keeper. Last week I asked you to hold both results at once, and there was nothing left to fall back on, because each had been bearable only by leaning on what the other had already removed: no recording, and no one keeping it. And the situation on the far side of that admits two opposite descriptions. One person reports that the barrier between himself and his own future, and between himself and other people, comes to seem less solid, and that his own death grows quiet, even consoling. Another, in the same position, reports only cold. Both reports are honest. Which is yours is not mine to say — and the last part of tonight leaves it that way.
So that is the situation as tonight begins. Steady again, but on different terms: the record is something the mind builds, not a tape it plays; the keeper is at most a stream, not a fixed owner; and you go on living regardless, because a day does not end when the account of what underlies it changes.
But I left one thing untouched last week, and pointed at it deliberately on the way out. It is the very thing you were doing a moment ago, when I began by having you set something aside. For all eight weeks of argument, you have been planning for a future self without once examining the practice — and treating it as the one solid, natural, unarguable thing left when everything else had come loose. Of course you save for your future self. Of course you look after your own. That, we tell ourselves, is not philosophy; it is simple arithmetic.
That assumption is the last one left, and tonight, before we close, we examine it. Not to talk you out of it — that is not the aim — but to show you something about it you have had no reason to notice: that it is not permanent human nature. It was made. It has a history, and very nearly a date. And once you can see that the saving, planning, investing self was assembled — that human beings have not always stood in time this way — the money you are about to set aside stops being arithmetic and becomes a question again. The question this series was about from the start. So keep that act in mind. We end where we began.
Let me state the assumption precisely, because it hides by being too obvious to notice.
It is this. You hold — not as an opinion you would defend in an argument, but as something more basic than opinion, a starting point you never think to question — that the person you will be in thirty years has a special claim on you now. Their comfort is worth your discomfort today; their security is worth a sacrifice from you. You will go without this year so that they need not go without in that year. And you do it automatically, without deliberation, because that future person is you. Providing for them is simply providing for yourself, extended across time. It does not feel like a choice. It feels like a fact you are obeying.
Now, notice something about how that assumption survived the whole series. Every argument we ran, over eight weeks, concerned one question: is the future person really you? Locke answered yes, provided the memories chain back to the present. Parfit answered that the question is empty — there is no deep fact of the matter either way, only more or less psychological connection. The animalist answered that you are the human organism, so the body persists whether or not the mind does. The chariot passage answered that there is no further "you" for the question to be about in the first place. Those were four of the six positions the series put on the table; all six remained live, and none won outright. We pushed the question until no one in the argument could produce, for inspection, the single continuous self that the saved money was supposedly for.
And the assumption was untouched by all of it. Consider: you would set that money aside whatever the metaphysics turned out to be. If Parfit is right, and "you" is only a name for certain connections, you would still save. If the animalist is right, and you are an organism gradually running down, you would still save. The assumption does not wait for an answer to whether the future person is you. It operates beneath that question, before it, regardless of how it comes out. Which means that eight weeks of dismantling passed it by entirely. We were examining the self; this assumption is not a claim about the self. It is something you do. And you cannot dismantle a practice by showing a metaphysical claim to be false. It simply remains in place, untouched.
So if we are to examine it — and tonight we are — we must question it differently. There are two ways to challenge anything you believe. The first is the one the series has used throughout: ask whether it is true. Is it true that you persist? Is it true that memory records? Call that the test of truth, and the assumption does not yield to it, because it is not a claim about what is true. So tonight we use the second method. We do not ask whether the assumption is true. We ask where it came from: who formed it, when, and what it replaced. Because some of what we take to be human nature really is human nature — and some of it is local. It has a date of origin. It was built by particular people, in a particular place, to meet a particular need, and then passed down so many times that its origins were forgotten, until it came to feel like a natural fact rather than something human beings had invented.
And I will tell you now where this leads, so that it does not take you by surprise: the saving, planning, investing self — the one setting money aside tonight — is a human invention, arrived at more recently than you would guess. That is the claim. Let me show you the argument for it.
One further thing before I do, because some of you will recognise the shape of tonight's question. Earlier — earlier than this series, in fact; in the series about what we owe a child drowning in front of us and a child starving on the other side of the world — we examined a stranger you will never meet who nonetheless has a claim on you. That was a stranger separated from you in space: the distant child. Tonight's is the same question moved out of space and into time: the stranger thirty years ahead. The structure is identical — a person whose welfare seems to demand a sacrifice from you, and you cannot quite say why it does, or how far the demand reaches — only relocated, from over there to up ahead. Hold that parallel in mind. We will return to it at the end.
Begin with the part hardest to feel, because you have never lived any other way: for most of human history, almost no one stood in time as you do.
Consider an ordinary life a thousand years ago — a farmer, a weaver, someone's daughter. Where would they be in thirty years? The answer was: here, doing this — the same work their parents had done and their children would do. Your position in the order of things was fixed before you were born: your station, your trade, your rank. The idea that you might manage your way into a different one — by planning, by putting something by, by working on yourself — would have sounded close to meaningless. And the future itself was not something you invested in. It belonged to God, or to fate, or to the turning of the seasons, which came round again and would come round after you were gone. Time was a cycle you were carried on, or a story whose ending was already written and was not yours to alter. The future was not something you owned a part of. It happened to you.
Now, a life like that was not freer or wiser than yours; I am not offering you a golden age. The point is narrower. The person in that life did not carry, inside them, the assumption you carry. They did not wake up managing a future self. There was no future self to manage, because the future was not theirs to build. The self that saves, defers, invests, and works on itself to become something later was not yet present. Someone had to assemble it. So who did, and when?
The best available answer to roughly when carries a name: the sociologist Max Weber, in his study The Protestant Ethic and the Spirit of Capitalism, published in 1905. Weber set out to explain why one particular part of the world — northern, Protestant Europe — produced this restless, calculating, self-managing way of being a person, and he traced it to a religious upheaval some centuries earlier. The short version — and I am compressing a long and careful book into a paragraph — runs as follows. A strict form of Protestant belief, the Calvinist form, left people in an unbearable position. Your eternal fate was already decided and sealed; you could not earn heaven through good works; and, worst of all, you could not know which way you had been assigned. The way people learned to live with that uncertainty was to read their own conduct for evidence — to treat a disciplined, sober, hard-working, methodical life as a sign that they were among the saved. Not as a way of buying salvation, which was impossible, but as a way of demonstrating it to themselves, by governing every hour.
Consider what that produces, slowly, across generations, even after the theology has faded. It produces a person who watches themselves. Who defers — who declines a pleasure now for the sake of something later. Who treats their own life as a project to be worked on with discipline, accounted for, and improved. Who experiences the future not as something that merely happens but as a result — something brought about by how rigorously one governs oneself in the present. That is the origin. Remove the religion, let a few centuries of commerce pass over it, and you arrive at a recognisable ancestor of the person you are: someone who manages themselves towards a future they hold themselves responsible for building.
Now I must be honest about what I am doing here, or I would be breaking my own rule. Weber did not write about the money you are setting aside tonight. He had no chapter on saving for retirement. What Weber supplies is one component — the methodical, self-watching, deferring person, and a rough sense of where that was formed. The connection I am drawing — from that Protestant self-discipline to your particular practice of investing in a future self — is mine; it is this series assembling the pieces, not a conclusion I am quoting from Weber's book. I say so plainly, so that no one leaves thinking a sociologist proved their retirement account is Calvinist. He did not. He supplied one part. There is a second part, from a very different thinker, and it tells us not only when this self appeared but what kind of thing it is. That is next.
The second thinker is the philosopher and historian Michel Foucault, and what he supplies is not another date but a way of seeing what kind of thing the planning self is.
Foucault spent his career on a single uncomfortable idea: that the selves we are do not come to us ready-made from nature; they come from practices — things a culture teaches people to do to themselves. He had a phrase for this, from a set of lectures he gave in 1982, published afterwards under the title "Technologies of the Self." The phrase sounds technical, so let me put it plainly. It means a thing you do to yourself, repeatedly and deliberately, to become a certain kind of person. Keeping a diary, to examine your conscience. Confessing, to learn to monitor your own desires. Going on a diet; keeping a budget; following a morning routine; tracking your steps; reviewing your goals. Each is a small procedure you perform on yourself, and its product is a self — a particular kind of person who did not exist until the procedure was devised and taught.
And here is why that matters tonight. If Foucault is right, then "I manage my future self" is not a discovery someone made about human nature, in the way we discovered that blood circulates. It is one of those procedures. It is something you were trained to do — by your parents, your school, the bank, the pension form; by a thousand small instructions to plan ahead, save, invest in yourself, consider where you want to be in five years. You have performed it so constantly, and began so young, that its product — the future-managing self — feels as though it was always simply there, part of the equipment you were born with. But it is a trained practice. Someone had to teach human beings to do it. Weber tells us roughly when the teaching began; Foucault tells us what it is — not your nature, but something you do to yourself so habitually that you can no longer feel yourself doing it.
And then the final piece falls into place, the one nearest to the money set aside. Somewhere in the last few centuries, the future itself was turned into a particular kind of object: something you can put money into and own a portion of. Consider what a retirement account actually is. It is the future, sold to you in advance, as property. You buy a share of a year that has not yet arrived — thirty years off — and you hold title to it now. Your own later life becomes an asset with a date attached, something that matures, like a bond. That is a very recent way to stand in time. The farmer of a thousand years ago could not buy a portion of the next decade and put their name to it; there was no financial instrument for it, and no self that would have wanted one. You can, and you do, and it feels as natural as breathing. Again — and I will keep being honest about this — Foucault did not write your pension statement either. The specific connection, from "selves are trained practices" to "the retirement-saving self in particular," is still this series doing the assembling. But the form of his argument is what I am working from: selves are made, by trained practices, within history, and then forget that they were made.
So this is the whole of it in a single statement, the one to carry into the last part of the episode. The planning self — the one setting money aside — is something that was made. It has a maker, a rough date, and a function it was built to serve. It is not a natural given; it is a human construction, arrived at by way of Calvinists and clerks and bankers and your own well-meaning parents, and so familiar through long use that it was mistaken for the natural order.
Now — and this is the most important point in the episode, so I will slow right down — none of that instructs you to stop setting the money aside. This is exactly where people go wrong with an argument of this kind, and I do not want you to go wrong with it. When you discover that something was made — that it has a history, a date, an inventor — there is a quick, cheap response that says: then it is fake, then it is arbitrary, then I may discard it. No. That does not follow, and it never has. Marriage was made; that does not make your love a fraud. Money was made; it still buys bread. Finding that a thing was constructed tells you that it was constructed. It does not tell you the thing is worthless, and it does not license you to walk away from it. What the history removes is more specific, and smaller, and harder to live with than "it is all fake." It removes one thing only: your entitlement to say, I plan for my future self because that is simply human nature, simply arithmetic, and there is nothing here to explain. That sentence is now closed to you. You can no longer place the practice beyond question by calling it natural, because you have watched it being made. The practice is still yours to continue. You have merely lost the one excuse that let you continue it without examination. And that — the loss of the excuse, not the loss of the self — is what the last part of the episode turns on.
So return to the money set aside — the provision for the person thirty years from now. You have been holding it in mind all hour. Three of the things you were leaning on, when you would have handed it over without a thought, are no longer where you left them.
The first. What you would have called a recording of your past is not one. You do not possess a faithful record of who you have been; the first episode established that, and nothing since has restored it. You may keep your memories. You have lost the right to be certain that any one of them happened as it feels to have happened.
The second — this is tonight's — the idea that planning for your future self is simply natural arithmetic: the bedrock, the thing too obvious to examine. It turns out to have a history. The saving, investing, self-managing self was assembled — by particular people, for particular reasons, more recently than you would have supposed — and so familiar that it was mistaken for a natural fact. It is still yours. It is simply no longer something you may call natural and decline to think about.
And the third, the deepest, the one the middle of the series spent a fortnight on: the self beneath all of it — the single, indivisible you that the money is for, the one continuous thing supposed to travel the whole way from here to that future and receive it — no one in the entire argument could produce it for inspection. Not Locke, not Parfit, not the monk who gave us the chariot, not I. We searched the record, and we searched for the owner, and both times we came back holding parts, and no further thing.
Now — this is the point at which the cheap version of tonight goes wrong. Hear precisely what all of that does not say. It does not say there is no self. Consider what remains standing. Perhaps you are an animal — a living organism that persists intact from the infant to the aged body, and the provision is for that organism, and that is the end of it. Perhaps you are a bundle of states, or a story you compose. Or — and this is the account that has stood untouched throughout the whole eight weeks — perhaps there really is a simple, further fact of you: one indivisible self, without parts, which no examination could ever turn up, precisely because it was never going to be among the parts you could lay out and point to. The defenders of that view have a clean reply to everything we did tonight: of course your search came back empty; you were looking for a further fact in an inventory of parts, and a further fact is not a part. We did not refute them. We never so much as touched them. They have not been answered tonight, and I will say so plainly. So what actually came loose is narrower, and harder, than "there is no self." What is gone is not the self. What is gone is your certainty — the quiet, complete certainty you arrived with, that you already knew which of these you are.
And here is what we will not do with that, because it would be the easiest thing in the world, and it would be a lie. We will not tell you the stranger is not worth it. Parfit himself, who took this argument furthest, found that as the barrier between himself and his future self grew thinner, it did not grow colder; it grew kinder. His concern reached beyond himself. His own death became less personal, less frightening — and the question of whether death is simply a bad thing, which the show will come to later, when we reach grief and dying, arrives here from an unexpected direction: thin that barrier, and dying itself becomes less fearful. That is one report. It is honest, and it is his. But here is the other, recorded by people just as honest, and I will not suppress it to send you home comfortable: stand at that same thinning barrier and you may find it cold. You stood at that barrier last week — one report warmer, one colder, both honest, neither refuted. Nothing tonight has settled which of them will be yours. The argument does not choose between them. Neither will we.
Because that is what the argument costs, and I now hand it to you. You are going to plan, and apologise to, and save for a person you will never meet and might not recognise — and you can no longer file it under "simply looking after myself," because no one in this argument could hand you, for inspection, the self that "myself" was pointing to; and the very practice of doing it turns out to be something your culture built and taught you. So the question is not whether you will do it. You will; the provision is already in hand. The question is whose life you are saving for — and whatever reason you now reach for, you must be able to look at it directly. Even the oldest reason, the one beneath all the others, the one you arrived with: it is automatically mine; it is simply me. Perhaps. An animalist might yet make that good; so might a defender of the simple, further self. But you can no longer simply help yourself to it — you cannot reach for "it is just me" without first saying which of these things you are. And that is the one question there is no skipping.
Eight weeks. Consider what you can do now that you could not when we began.
You arrived holding the most settled thing a person owns — the sense that there is one continuous you at the centre of your life, who remembers, who persists, to whom the future belongs; the thing beneath all the other things, too obvious to question. And over eight weeks you learned the single practice this whole programme is built on: to take what you are most certain of, and to find the standpoint concealed underneath it. You found it under your memory — the recording that was never a recording. You found it under the owner — the keeper behind your eyes who, when you reached for him, was not there. And tonight you found it under the last assumption left, the planning self, which turned out to have a maker and a date. That is a capacity you now hold, not a fact you were handed. You can apply it to anything you are sure of. And you did the harder half as well: twice in this series you took the two views you most wanted to dismiss — that you are merely an animal running down, that there is no self there at all — and instead you held them at their strongest, and stated the strongest case each could make, in the way you first learned to do in the earlier series, What You Owe a Stranger, faced with a demand you did not want to meet. You did it then with a stranger's life. Tonight you did it with your own. That is yours to keep — not as an answer, since I never gave you one, but as something you now know how to do. And the show is not finished with the inner life. Where it goes next stays within — from the self across time to the self among other people: loneliness, friendship, and being alone, and the uncomfortable possibility that what you reach for to ease the ache may not ease it, and that you may need more of the solitude you have been avoiding, not less. But that is for another week.
Tonight, one last thing before you go. Find the early photograph — the child of four you have been calling by your own name your whole life, the one you cannot remember being. Eight weeks, and you still cannot say for certain that she is you. And tonight you will set money aside for a person thirty years ahead you have never met, and might walk past in the street. A stranger behind you; a stranger in front; and, in the narrow present between them, someone signing the cheque. Whether the three of them are one person — and on what authority you say so — is the question you came in certain you had already answered. Look at the photograph. You are not certain now.
Thanks for listening.
