In the first part of this post, I briefly went over some of the larger problems that our global society is currently facing, including the problem of overpopulation and the overall lack of environmental and economic sustainability. I also mentioned some of the systematic and ideological (including religious and political) barriers that will need to be overcome before we can make any considerable progress in obtaining a sustainable future.
Although it may seem hopeless at times, I believe that we human beings – despite our cognitive biases and vulnerability to irrational and dogmatic behaviors – have an innate moral core in common that is driven by the incentive to increase our level of overall satisfaction and fulfillment in life. When people feel like they are living more fulfilling lives, they want to continue if not amplify the behavior that’s leading to that satisfaction. If a person is shown ways that lead to greater satisfaction and they are able to experience even a slight though noticeable improvement as a result of those prescriptions, I believe that even irrational and dogmatic people do begin to explore outside of their ideological box.
More importantly however, if everyone is shown that their level of satisfaction and fulfillment in life is ultimately a result of their doing what they feel they ought to do above all else (which is morality in a nutshell), then they can begin to recognize the importance and efficacy of basing those oughts on well-informed facts about the world. In other words, people can begin to universally derive every moral ought from a well-informed is, thus formulating their morality based on facts and empirical data and grounded on reason – as opposed to basing their morality on dogmatic and other unreliable beliefs in the supernatural. It’s easy for people to disagree on morals that are based on dogma and the supernatural, because those supernatural beliefs and sources of dogma vary so much from one culture and religion to another, but morals become common if not universal (in at least some cases) when they are based on facts about the world (including objective physical and psychological consequences not only for the person performing the moral action, but also for anyone on the receiving end of that moral action).
Moral Imperatives & Happiness
Science has slowly but surely been uncovering (or at least better approximating) what kinds of behaviors lead to the greatest levels of happiness and overall satisfaction in the collective lives of everyone in society. Since all morals arguably reduce to a special type of hypothetical imperative (i.e. if your fundamental goal is X, then you ought to do Y above all else), and since all goals ultimately reduce to the fundamental goal of increasing one’s life satisfaction and fulfillment, then there exist objective moral facts, whereby if they were known, they would inform a person of which behaviors they ought to do above all else in order to increase their happiness and fulfillment in life. Science may never be able to determine exactly what these objective moral facts are, but it is certainly logical to assume that they exist, namely some ideal set of behaviors for people (at least, those that are sane and non-psychopathic) which, if we only knew what those ideal behaviors were, they would necessarily lead to maximized satisfaction within every person’s life (a concept that has been proposed by many philosophers, and one which has been very well defended in Richard Carrier’s Goal Theory of Ethics).
What science can do however, and arguably what it has already been doing, is to continue to better approximate what these objective moral facts are as we accumulate more knowledge and evidence in psychology, neuroscience, sociology, and even other fields such as economics. What science appears to have found thus far is (among other things) a confirmation of what Aristotle had asserted over two thousand years ago, namely the importance of cultivating what have often been called moral virtues (such as compassion, honesty, and reasonableness), in order to achieve what the Greeks called eudaimonia, or an ultimate happiness with one’s life. This makes perfect sense because cultivating these virtues leads to a person feeling good while exercising behaviors that are also beneficial to everyone else, so then benefiting others is rarely if ever going to feel like a chore (which is an unfortunate side-effect of exclusively employing the moral duty mentality under Kant’s famous deontological ethical framework). Combine this virtue cultivation with the plethora of knowledge about the consequences of our actions that the sciences have been accumulating, thus integrating in John Stuart Mill’s utilitarian or teleological/consequentialist ethical framework, and then we have a good ethical framework that should work very effectively in leading us toward a future where more and more people are happy, fulfilled, and doing what is best for sustaining that happiness in one another, including sustaining the environment that their happiness is dependent on.
A Science of Morality
To give a fairly basic but good example of where science is leading us in terms of morality, consider the fact that science has shown that when people try to achieve ever-increasing levels of wealth at the expense of others, they are doing so because those people believe that wealth will bring them the most satisfaction in life, and thus they believe that maximizing that wealth will bring maximal happiness. However, this belief is incorrect for a number of reasons. For one, studies in psychology have shown that there is a diminishing return of happiness when one increases their income and wealth – which sharply diminishes once a person exceeds an income of about $70K per year (in U.S. dollars / purchasing power). So the idea that increasing one’s income or wealth will indefinitely increase their happiness isn’t supported by the evidence. At best, it has a limited effect on happiness that only works up to a point.
Beyond this, psychology has also shown that there are much more effective ways of increasing happiness, such as cultivating the aforementioned virtues (e.g. compassion, integrity, honesty, reasonableness, etc.) and exercising them while helping others, which leads to internal psychological benefits (which neuroscience can and has quantified to some degree) and also external sociological benefits such as the formation of meaningful relationships which in turn provide even more happiness over time. If we also take into account the amount of time and effort often required to earn more income and wealth (with the intention of producing happiness), it can be shown that the time and effort would have been better spent on trying to form meaningful relationships and cultivating various virtues. Furthermore, if those people gaining wealth could see first hand the negative side-effects that their accumulation of wealth has on many others (such as increased poverty), then doing so would no longer make them as happy. So indeed it can be shown that their belief of what they think maximizes their satisfaction is false, and it can also be shown that there are in fact better ways to increase their happiness and life satisfaction more than they ever thought possible. Perhaps most importantly, it can be shown that the ways to make them happiest also serve to make everyone else happier too.
A Clear Path to Maximizing (Sustainable) Happiness
Perhaps if we begin to invest more in the development and propagation of a science of morality, we’ll start to see many societal problems dissolve away simply because more and more people will begin to realize that the reason why we all think that certain actions are moral actions (i.e. that we ought to do them above all else), is because we feel that doing those actions brings us the most happy and fulfilling lives. If people are then shown much more effective ways that they can increase their happiness and fulfillment, including by maximizing their ability to help others achieve the same ends, then they’re extremely likely to follow those prescribed ways of living, for it could be shown that not doing so would prevent them from gaining the very maximal happiness and fulfillment that they are ultimately striving for. The only reason people wouldn’t heed such advice then is because they are being irrational, which means we need to simultaneously work on educating everyone about our cognitive biases, how to spot logical fallacies and avoid making them, etc. So then solving society’s problems, such as overpopulation, socioeconomic inequality, or unsustainability, boils down to every individual as well as the collective whole accumulating as many facts as possible about what can maximize our life satisfaction (both now and in the future), and then heeding those facts to determine what we ought to do above all else to achieve those ends. This is ultimately an empirical question, and a science of morality can help us discover what these facts are.
