One of the complaints about science is that it does not offer any moral guidance. It can describe reality and causal relationships but it does not tell us how we should behave. One can accept such a situation as a fact of life but most people are drawn towards belief systems that do offer such moral guidance. What is interesting about Buddhism, or at least its more (modern) secular versions, is that it both seeks to understand reality and to offer moral and “spiritual” guidance as well. This of course presents a problem. Science also seeks to understand reality but the consensus is that if there is anything we are learning about reality it is that life has no objective meaning and the idea of objective, person-independent morality is an illusion.
One of the perplexing things about Buddhism is the assumption that gaining a correct understanding of Reality (typically written with a capital R) will trigger a corresponding change in our moral outlook. For example, when a person comes to realize that the “self” is an illusion, a lot of moral misconduct will disappear. Unfortunately, getting rid of such “illusions” about the self is neither sufficient nor necessary for moral progress. Great moral progress has been made in countries where people are firm believers in the existence of an unchanging self and many moral defects have been identified in countries where a belief in the illusion of the self is encouraged. In fact, the belief in a self is interesting because it has been both praised as a guard against nihilism and as an illusion that undermines morality.
Despite its appearance of being a secular open-minded belief system, Buddhism rests on a rather strong premise about the beneficial effects of seeing the “real” nature of reality. But contemporary science does not support such strong statements about reality. Like any other topic in science, our understanding of reality is subject to continuous revision. It might even be possible that we live in a computer simulation and “reality” outside of it is quite different from what Buddhists believe.
One of the most level-headed discussions of Buddhism and science is Donald S. Lopez’s Buddhism and Science: A Guide for the Perplexed. This book is a detailed exposition of the history of discussions about the compatibility of Buddhism and science. The author recognizes that the position that Buddhism is compatible with, or even supported by, science is as old as Buddhism itself and provides reasons why Buddhism more than any other “religion” is prone to such statements. In the end, however, Buddhism is recognized as a rather diverse and dynamic belief system and whether it is compatible with science depends on what is exactly meant by “science” and “Buddhism.” It is clear that a lot of historical expositions of Buddhism contain claims that are now known to be scientifically incorrect. This raises the question how much of Buddhism can be rejected before it is no longer Buddhism.
One of the most uncomfortable claims in Buddhism concern the origin and nature of the universe. As Lopez writes, “all of the religions of the world asserted that the world is flat. This belief, in turn, was held so tenaciously that when it was first suggested that the world is not flat, those who made such a suggestion were executed.” Most secular Buddhists would not mind claiming that the Buddha was wrong about this and that these beliefs are not the essential doctrines of Buddhism, but as Lopez writes, “yet once the process of demythologizing begins, once the process of deciding between the essential and inessential is under way, it often difficult to know where to stop.” Which raises, once more, the question of why not to reject Buddhism completely and embrace a thorough scientific, empiricist perspective on life.
A counter argument is that Buddhism offers things that science cannot offer such as deeper metaphysical insights into the nature of reality and ethical truths. But the modern scientific mind is exactly distinguished by claiming that no objective truths should be expected here. In particular, there is no credible method, to deduce such ethical truths from metaphysical “facts.” There are not many rigorous analytic philosophical treatments of Buddhism but those that exist, such as Mark Siderits’ Buddhism as Philosophy: An Introduction, have identified several problems and challenges. If Buddhism (even in its most modern, secular, form) is subjected to the kind of scrutiny that has been applied to thinkers such as Wittgenstein, Carnap, and Kant it is not likely that it can survive in its current form. At best it will be just another philosophical “school.”
A very sympathetic account of Buddhism, and its relation to contemporary (neuro)science and philosophy is Owen Flanagan’s The Bodhisattva’s Brain: Buddhism Naturalized. Flanagan goes out of his way to give the most charitable reading of modern secular Buddhism but in the end he confesses, “I still do not see, despite trying to see for many years, why understanding the impermanence of everything including myself makes a life of maximal compassion more rational than a life of hedonism.” Perhaps this is because there simply is no necessary, logical, connection between recognizing the nature of Reality and specific moral and lifestyle choices. While Buddhists usually do not like being accused of being negative and pessimistic it can hardly be denied that more cheerful, care-free, implications of the idea of impermanence can be imagined (and have been imagined).
How would Buddhism look like if it really would be serious about making adjustments to its (core) beliefs based on science? For starters, it would treat each belief as an hypothesis that is calibrated when new evidence becomes available. But how many Buddhist publications are really serious about this? Such work is typically done by sympathetic outsiders but the result never produces a full endorsement of core Buddhist beliefs. Although Buddhism seems to be able to survive in a modern secular society it still has its share of ex-Buddhists who feel that it is still too dogmatic and unscientific. In his article “Why I ditched Buddhism” John Horgan writes:
“All religions, including Buddhism, stem from our narcissistic wish to believe that the universe was created for our benefit, as a stage for our spiritual quests. In contrast, science tells us that we are incidental, accidental. Far from being the raison d’être of the universe, we appeared through sheer happenstance, and we could vanish in the same way. This is not a comforting viewpoint, but science, unlike religion, seeks truth regardless of how it makes us feel. Buddhism raises radical questions about our inner and outer reality, but it is finally not radical enough to accommodate science’s disturbing perspective. The remaining question is whether any form of spirituality can.”
There is one element in Buddhist thinking, however, that can throw an interesting light on the “political mind.” Buddhism is not explicitly political although some followers have made attempts to politicize it, culminating in a rather artificial movement called “Engaged Buddhism.” Buddhism teaches that nothing in reality is permanent and emphasizes the continuous birth, transformation, and rebirth of things. What sets the political mind apart is that it looks at society as a whole and wants it to conform to an arbitrary idea about political justice or efficiency. While this aim can be even perceived as unrealistic and delusional for a small group, it borders on insanity for a world composed of billions of people. When political activists recognize that the world cannot be easily manipulated in such a fashion, or run into the unintended consequences of their policies, frustration, anger, and violence often ensue. This “thirst” for control of the external world has often been ridiculed by Zen Buddhist monks and this kind of “suffering” can be successfully eliminated if the ever-changing nature of reality is recognized.
There is a growing literature about the psychology and even neuroscience of political beliefs but much of this work does not examine the most basic questions. What exactly is a political belief (or ideology)? Why do some people choose political engagement and others seek to make less grandiose changes to their personal lives and environment? Can political ideals be satisfied or does the ever-changing nature of reality (and slight deviations from any ideal) suggest that politically engaged people chase an illusion and political happiness will be brief at best. To my knowledge, there have not been many publications in which Buddhist premises have been employed to argue against the idea of political ideology and “activism”, although it seems an interesting connection to make. Such a Buddhist argument would solely emphasize personal kindness instead of the (futile) desire to make the world conform to a specific idea (and the ensuing “suffering” if reality does not want to conform).
