Egoism For the last two classes, we have been discussing the question of whether any actions are really objectively right or wrong, independently of the standards of any person or group, and whether any one is ever really morally responsible for their actions. Today we turn to a different topic; we will concede that some actions are objectively right or wrong, and ask: is it possible for people to ever act morally? This might seem like a silly question. But most views of ethics imply that, in at least some circumstances, we ought to set aside our own interests in favor of the interests of other people, or other things. But, you might think, any such view is in trouble from the start -- after all, aren’t all human actions done in self-interest? The view that all of our actions are done in self-interest is called psychological egoism. Psychological egoism is a universal claim: it is a claim about all human actions; the idea is that something in the nature of human beings, or in the nature of intentional action, implies that genuine altruistic action -- action done for the sake of others rather than oneself -- is impossible for human beings. So it is important to distinguish psychological egoism from the claim that human beings sometimes, or quite often, act out of their own self-interest. These claims are so obviously correct as to be hardly worth discussing. The psychological egoist doesn’t just claim that some actions are done for self- interested reasons, but that all are. It should also be distinguished from the claim that we ought to act out of our own self-interest. This is a claim about what our actions ought to be like whereas psychological egoism is a claim about what they always in fact are like. The view that all of our actions are done in self-interest is called psychological egoism. A second question we need to ask to understand the view is: what does it mean for an action to be self-interested? One appealingly simple answer to this question is called hedonistic psychological egoism. This is the view stated by Jeremy Bentham in the following passage. According to this view, all human actions are self-interested in the sense that they all aim at the pleasure of the person performing the action. So, on this view, all of our actions are done in the interest of causing a certain sensation in us: the sensation of pleasure. Is this true? Do we always act in the way that we think will bring about the most pleasure? Consider, for example, eating when you are very hungry. Perhaps sometimes we eat in order to cause pleasurable taste sensations; but surely this is not the case every time we eat. Or consider my changing my daughter’s diaper. This is often something which fails to cause sensations of pleasure, and yet it is surely something that I do intentionally quite often. The view that all of our actions are done in self-interest is called psychological egoism. A second question we need to ask to understand the view is: what does it mean for an action to be self-interested? One appealingly simple answer to this question is called hedonistic psychological egoism. This is the view stated by Jeremy Bentham in the following passage. According to this view, all human actions are self-interested in the sense that they all aim at the pleasure of the person performing the action. So, on this view, all of our actions are done in the interest of causing a certain sensation in us: the sensation of pleasure. Consider, for example, eating when you are very hungry. Perhaps sometimes we eat in order to cause pleasurable taste sensations; but surely this is not the case every time we eat. Or consider my changing my daughter’s diaper. This is often something which fails to cause sensations of pleasure, and yet it is surely something that I do intentionally quite often. About any such case, the hedonistic psychological egoist can come up with something to say. For example, he can say that in the case of the diaper changing, that I believe that changing this diaper will lead to her being healthy, and observation of her being healthy will cause feelings of pleasure in me. Are explanations of this sort plausible? Should they convince someone who is not already a psychological egoist? The view that all of our actions are done in self-interest is called psychological egoism. Of course, to raise problems with hedonistic psychological egoism is not to show that psychological egoism is false -- it just shows that the psychological egoist should come up with some definition of “self-interested action” other than “action which aims at bringing about sensations of pleasure in the agent.” One intuitively plausible idea about how to do this is to say that self-interested actions are those in which the person performing the action aims at satisfaction of his or her own desires. Let’s call this desire satisfaction psychological egoism. What does it mean to say that I always aim at the satisfaction of my desires? Here is one interpretation: every time I do something on purpose, I am moved to action by some desire of mine. And, in every such case, the desire which moves me to action is a special kind of desire: it is a desire that some other desire be satisfied. For example, consider my action of showing up for lecture today. Perhaps it is the case that I was sitting in my office, considering my various desires, and found among them my desire not to be fired. I then came to desire that this desire not to be fired be satisfied, and it was this that caused me to come to lecture. Maybe some actions are like this, but it is not very plausible that all actions are like this. For one thing, it makes actions way more sophisticated than they plausibly are. It seems that in many cases I am moved to action by a desire like a desire to get out of the cold, or a desire for pleasure --- I am not always moved to action by a desire about another desire. We need to come up with a better interpretation of the idea that all actions are aimed at the satisfaction of our own desires. The view that all of our actions are done in self-interest is called psychological egoism. One intuitively plausible idea about how to do this is to say that self-interested actions are those in which the person performing the action aims at satisfaction of his or her own desires. Let’s call this desire satisfaction psychological egoism. The example of Jane does not show that psychological egoism is false -- the psychological egoist can just deny that there are, or ever have been, any people like Jane. But it does show that something is wrong with this form of argument: Everyone’s actions are caused by their own desires. ----------------------------------------------------------- Everyone’s actions are selfish. After all, Jane is a possible example of someone whose actions are caused by their own desires, but who is not motivated by self-interest. So this argument can’t be valid. How could the psychological egoist repair this defect in the argument? One plausible idea is to add a premise to the argument, as follows: Everyone’s actions are caused by their own desires. Everyone’s desires are all, ultimately, only desires for their own well-being or self-interest. ----------------------------------------------------------- Everyone’s actions are selfish. Arguably, adding this premise makes the argument valid. Is the argument as stated a convincing one? The view that all of our actions are done in self-interest is called psychological egoism. One intuitively plausible idea about how to do this is to say that self-interested actions are those in which the person performing the action aims at satisfaction of his or her own desires. Let’s call this desire satisfaction psychological egoism. We can sum up our discussion of the ‘desire satisfaction’ version of psychological egoism as follows. On one interpretation of the theory, it says that we always act out of a desire that some desire of ours be satisfied. This interpretation seems implausible, because we sometimes act out of a desire for something -- like chocolate, or money -- other than one of our own desires. On a second interpretation of the theory, it says that we always act out of our own desires. This version of the theory seems to be true, but it does not seem to imply that we always act out of self- interest. To get this result, we need to add the assumption that all of our desires are self-interested, which is (at least closely related to) what we were trying to establish. But the psychological egoist is not out of options. Let’s consider a third version of psychological egoism, which defines ‘self-interested actions’ as ‘actions done in order to increase one’s own welfare or well-being.’ Let’s call this welfare psychological egoism. The view that all of our actions are done in self-interest is called psychological egoism. But the psychological egoist is not out of options. Let’s consider a third version of psychological egoism, which defines ‘self-interested actions’ as ‘actions done in order to increase one’s own welfare or well-being.’ Let’s call this welfare psychological egoism. This is similar in form to hedonistic psychological egoism, but aims to improve upon that theory by allowing that we sometimes have self-interested motives other than desire for sensations of pleasure. So, for example, sometimes we might eat food to satisfy our hunger, rather than just to cause sensations of pleasure. Why might we believe this sort of view? One sort of argument might be based on the idea that humans evolved by natural selection. Oversimplifying, the theory of evolution by natural selection leads us to expect, in general, that evolution will favor those traits which improve the chances of the the bearer of the trait having a relatively large number of viable offspring. So, if this theory is correct, we should expect that the tendency to help others at the expense of one’s own reproductive prospects will not be passed on to future generations -- unless that tendency leads, in some other way, to the propagation of your own genes. This last point might help to explain the example of diaper-changing we discussed above. Perhaps in that sort of case, I am not acting directly in my own self-interest, but am acting in the interest of the propagation of my own genes, by doing what I can to ensure that my daughter will remain healthy until an age at which she too will be able to reproduce, and hence pass along (in part) my genetic material. One clear and popular example of this sort of argument is the book The Red Queen, by Matthew Ridley, in which he claims “no creature could ever evolve the ability to help its species at the expense of itself.” The view that all of our actions are done in self-interest is called psychological egoism. But the psychological egoist is not out of options. Let’s consider a third version of psychological egoism, which defines ‘self-interested actions’ as ‘actions done in order to increase one’s own welfare or well-being.’ Let’s call this welfare psychological egoism. In our other reading for today, though, Glaucon gives what can be thought of as another sort of argument for psychological egoism. This is based on the example of the ring of Gyges: a ring which renders its wearer invisible, and hence makes his actions free from any consequences which might result from the opinions of others. Suppose that Glaucon is right, and that everyone would act this way if they had the ring of Gyges in their possession. What would this show about our actual behavior? Would it show that it was self-interested in some way? If so, why? The view that all of our actions are done in self-interest is called psychological egoism. But the psychological egoist is not out of options. Let’s consider a third version of psychological egoism, which defines ‘self-interested actions’ as ‘actions done in order to increase one’s own welfare or well-being.’ Let’s call this welfare psychological egoism. Setting this example to the side, it must be conceded there are many examples of actions which seem problematic from the point of view of welfare psychological egoism. For example, we talked about the welfare psychological egoist’s explanation of me changing my daughter’s diaper in terms of transmission of my genes. But what about adoption? Many adoptive parents do enormous amounts for their children, with no chance that their genes will be transmitted to that child’s offspring. And there are many other cases, perhaps the clearest of which are cases of self-sacrifice. These can be extreme -- giving your life to save others in a war, for example -- or minimal, like a case in which you hold a door for someone in bad weather even though you are cold and don’t feel like it, and are in a strange city and never expect to see them again. As with our discussion of hedonistic psychological egoism, we can concoct stories about how these actions could be aimed at increasing one’s welfare: for example, the soldier could be doing this to avoid feelings of shame in the future, and the door could be held in the expectation that that person will do similar things for you in the future. The problem is that, as with the examples discussed in connection with hedonistic psychological egoism, these explanations seem a bit forced. One way to see this is by looking at the implausible ascriptions of beliefs they require: does the soldier really think that the shame would be so great that the best way to maximize his own well-being is immediate death which avoids the shame? Does the person holding the door really hold the wildly implausible belief that they will see this person again, and that this person will be in a position to help them, or improve their reputation? The view that all of our actions are done in self-interest is called psychological egoism. To sum up, we have considered three attempts to explain what, exactly, the psychological egoist’s thesis amounts to. The first, hedonistic psychological egoism, seems wildly implausible; we perform many actions which we do not expect to lead to our own pleasure. The second, desire satisfaction psychological egoism, is much more plausible, but is not really a version of psychological egoism, since an action can be driven by one of my desires without being self-interested, so long as the desire is not self-interested. The third, welfare psychological egoism, also faces some difficult counterexamples, and the attempt to establish this thesis on the basis of the fact that human beings evolved by natural selection seems to be a failure. So, for now, let’s assume that psychological egoism is false, and that it is possible to do something which is morally right even though contrary to at least some sorts of self-interest. We might still ask: why should anyone ever do this? Why be moral? So, for now, let’s assume that psychological egoism is false, and that it is possible to do something which is morally right even though contrary to at least some sorts of self-interest. We might still ask: why should anyone ever do this? Why be moral? But one might still wonder whether we can give any explanation of why it is rational to be moral which does not build in the assumption that, all things considered, we always have most reason to do what is morally right. One possibility is that morality is, even if not in our individual self-interest, at least in our collective self- interest. This is sometimes illustrated by consideration of the following sort of situation: The prisoner’s dilemma You are one of two prisoners arrested for a crime. You, and the other prisoner, are each rational, and you each know that if you both stay silent, and don’t confess, you will each be convicted of a fairly minor crime, and get 2 years in jail each. If you turn State’s evidence and the other prisoner stays silent, then you will get off with nothing, and the other prisoner will get 10 years; exactly the opposite will happen if the other prisoner turns State’s evidence, and you stay silent. If you both confess, you both get 5 years. Is it rational for you to confess, or stay silent? How should you reason about this situation? Is it rational to keep silent, or turn State’s evidence? Suppose that we think that it is rational to turn State’s evidence. How might this be used to support the view that it is rational to be moral? So, for now, let’s assume that psychological egoism is false, and that it is possible to do something which is morally right even though contrary to at least some sorts of self-interest. We might still ask: why should anyone ever do this? Why be moral? But one might still wonder whether we can give any explanation of why it is rational to be moral which does not build in the assumption that, all things considered, we always have most reason to do what is morally right. One way to dramatize this question of whether we can give any non-circular argument in favor of acting morally is by considering the position of a rational egoist: someone who holds that they always have most reason to serve their own interests. Is there any argument which could show the rational egoist that he is irrational? Here is one attempt to provide such an argument. It seems that one sort of irrationality results from treating like cases differently: for example, if one responds to an identical bet differently on different days, and can provide no reason for this different response, this seems to be a kind of practical irrationality. Arbitrariness of this sort is irrational. But isn’t the rational egoist arbitrary in just this way? The rational egoist should agree that he is a being of the same sort as other people, and hence that his interests are things of the same sort as the interests of others. But in deciding what to do, he takes his own interests into account, but not the interests of others. Why isn’t this just the sort of arbitrariness that seems to be a mark of irrationality? This is not a direct justification of morality, but rather a critique of an opposed view. But to the extent that one takes rational egoism and morality to be the two most plausible ways of guiding one’s behavior, this sort of argument against rational egoism might be a sort of indirect justification of morality.
