Reason's capacity to take us where we did not expect to go could also lead to a curious diversion from what one might expect to be the straight line of evolution. We have evolved a capacity to reason because it helps us to survive and reproduce. But if reason is an escalator, then although the first part of the journey may help us to survive and reproduce, we may go further than we needed to go for this purpose alone. We may even end up somewhere that creates tension with other aspects of our nature. In this respect, there may after all be some validity in Kant's picture of tension between our capacity to reason, and what it may lead us to see as the right thing to do, and our more basic desires. We can live with the contradictions only up to a point. Here is an example, from Gunnar Myrdal's "An American Dilemma": The individual ... does not act in moral isolation. He is not left alone to manage his rationalizations as he pleases, without interference from outside. His valuations will, instead, be questioned and disputed.... The feeling of need for logical consistency within the hierarchy of moral valuations -- and the embarrassed and sometimes distressed feeling that the moral order is shaky --- is, in its modern intensity, a rather new phenomenon. Our ability to reason can be a factor in leading us away from both arbitrary subjectivism and an uncritical acceptance of the values of our community. Reason makes it possible to see ourselves in this way because, by thinking about my place in the world, I am able to see that I am just one being among others, with interests and desires like others. I have a personal perspective on the world, from which my interests are at the front and center of the stage, the interests of my family and friends are close behind, and the interests of strangers are pushed to the back and sides. But reason enables me to see that others have similarly subjective perspectives, and that from "the point of view of the universe" my perspective is no more privileged than theirs. Thus my ability to reason shows me the possibility of detaching myself from my own perspective and shows me what the universe might look like if I had no personal perspective. Consistent with the idea of taking the point of view of the universe, the major ethical traditions all accept, in some form or other, a version of the golden rule that encourages equal consideration of interests. "Love your neighbor as yourself," said Jesus. "What is hateful to you do not do to your neighbor," says Rabbi Hillel. Confucious summed up his teaching in very similar terms: "What you do not want done to yourself, do not do to others." The "Mahabharata," the great Indian epic, says: "Let no man do to another that which would be repugnant to himself." The parallels are striking. The perspective on ourselves that we get when we take the point of view of the universe yields as much objectivity as we need if we are to find a cause that is worthwhile in a way that is independent of our own desires. The most obvious such cause is the reduction of pain and suffering, wherever it is to be found. This may not be the only rationally grounded value, but it is the most immediate, pressing, and universally agreed upon one. We know from our experience that when pain and suffering are acute, all other values recede into the background. If we take the point of view of the universe, we can recognize the urgency of doing something about the pain and suffering of others, before we even consider promoting (for their own sake rather than as a means to reducing pain and suffering) other possible values like beauty, knowledge, autonomy, or happiness. The possibility of taking the point of view of the universe overcomes the problem of finding meaning in our lives, despite the ephemeral nature of human existence when measured against all the eons of eternity. Suppose that we become involved in a project to help a small community in a developing country to become free of debt and self-sufficient in food. The project is an outstanding success.... Now someone might say: "What good have you done? In a thousand years these people will all be dead, and their children and grandchildren as well, and nothing that you have done will make any difference." That may be true, or it might be false. The changes we make today could snowball and, over a long period of time, lead to much more far-reaching changes. Or they could come to nothing. We simply cannot tell. We should not, however, think of our efforts as wasted unless they endure forever, or even for a very long time. We can make the world a better place by causing there to be less pointless suffering in one particular place, at one particular time, than there would otherwise have been. As long as we do not thereby increase suffering at some other place or time, or cause any other comparable loss of value, we will have had a positive effect on the universe. I am not defending the objectivity of ethics in the traditional sense. Ethical truths are not written into the fabric of the universe: to that extent the subjectivist is correct. If there were no beings with desires or preferences of any kind, nothing would be of value, and ethics would lack all content. On the other hand, once there are beings with desires, there are values that are not only the subjective values of each individual being. The possibility of being led, by reasoning, to the point of view of the universe provides as much "objectivity" as there can be. When my ability to reason shows me that the suffering of another being is very similar to my own suffering and (in an appropriate case) matters just as much to that other being as my own suffering matters to me, then my reason is showing me something that is undeniably true. In a society in which the narrow pursuit of material self-interest is the norm, the shift to an ethical stance is more radical than many people realize. In comparison with the needs of people starving in Somalia, the desire to sample the wines of the leading French vineyards pales into insignificance. Judged against the suffering of immobilized rabbits having shampoos dripped into their eyes, a better shampoo becomes an unworthy goal. An ethical approach to life does not forbid having fun or enjoying food and wine, but it changes our sense of priorities. The effort and expense put into buying fashionable clothes, the endless search for more and more refined gastronomic pleasures, the astonishing additional expense that marks out the prestige car market in cars from the market in cars for people who just want a reliable means to getting from A to B -- all these become disproportionate to people who can shift perspective long enough to take themselves, at least for a time, out of the spotlight. If a higher ethical consciousness spreads, it will utterly change the society in which we live. We cannot expect that this higher ethical consciousness will become universal. There will always be people who don't care for anyone or anything, not even for themselves. There will be others, more numerous and more calculating, who earn a living by taking advantage of others, especially the poor and the powerless. We cannot afford to wait for some coming glorious day when everyone will live in loving peace and harmony with everyone else. For a long time to come, the world is going to remain a tough place in which to live. Nevertheless, we are part of this world and there is a desperate need to do something now about the conditions in which beings live and die. There is no time to focus our thoughts on the possibility of a distant utopian future. Too many humans and nonhuman animals are suffering now. We have to take the first step. We must reinstate the idea of living an ethical life as a realistic and viable alternative to the present dominance of materialist self-interest. If a critical mass of people with new priorities were to emerge, and if these people were seen to do well, in every sense of the term -- if their cooperation with each other brings reciprocal benefits, if they find joy and fulfillment in their lives -- then the ethical attitude will spread, and the conflict between ethics and self-interest will have been shown to be overcome, not by abstract reasoning alone, but by adopting the ethical life as a practical way of living and showing that it works, psychologically, socially, and ecologically. Anyone can become part of the critical mass that offers us a chance of improving the world before it is too late. You can rethink your goals and question what you are doing with your life. That might mean quitting your job, selling your house, and going to work for a voluntary organization in India. More often, the commitment to a more ethical way of living will be the first step of a gradual but far-reaching evolution in your lifestyle and in your thinking about your place in the world. One thing is certain: you will find plenty of worthwhile things to do. You will not be bored or lack fulfillment in your life. Most important of all, you will know that you have not lived and died for nothing, because you will have become part of the great tradition of those who have responded to the amount of pain and suffering in the universe by trying to make the world a better place.
