There is More To Science than Dreamt Of by the Dalai Lama
The Dalai Lama clearly has a long-standing and genuine interest in science. He has access to the best minds in science, and hosts an annual conference on science. To his credit, he is humble about his limited understanding, and does not claim to have divine knowledge about what is true science. While he faithfully records what the scientists tell him in the book, it seems that he does not always understand them.
On page 12 he presents a concise summary of his philosophy of science, tied together with dubious logic. Unfortunately it ignores what the scientists told him. As it nicely sums up what is wrong in this otherwise worthwhile book, this review will examine it in detail, rather than evaluate the entire book.
“I have noticed that many people hold an assumption that the scientific view of the world should be the basis for all knowledge and all that is knowable. This is scientific materialism.”
The scientific view of the world is that it is comprehensible. We can explain what we observe by conjecturing rules, and testing to ensure they work. As our knowledge and investigative tools improve, we can observe new things that were unimaginable before. So science is the basis for all that is observable, remembering that there is always much more to be discovered. Ideas are an integral part of the reality that science investigates. Science itself is driven by our creativity, inventing new ideas to explain how the world works. “Scientific Materialism” is misleading if it means that scientific method is excluded from studying our mental processes or philosophy.
“This view upholds a belief in an objective world, independent of the contingency of its observers. It assumes that the data being analyzed within an experiment are independent of the preconceptions, perceptions, and experience of the scientist analyzing them.”
Science is indeed based on the concept of a single objective reality. The confusion here comes from the distinction between the reality of an object and our observation of it. Observation is certainly affected by the expectations and techniques of the scientist. Science is about overcoming these biases to arrive at an ever-improving approximation of the truth. The fact that we do not know exactly what is the truth does not mean there is no truth at all. This is a false dichotomy.
“Underlying this view is the assumption that, in the final analysis, matter, as it can be described by physics and as it is governed by the laws of physics, is all there is. Accordingly, this view would uphold that psychology can be reduced to biology, biology to chemistry, and chemistry to physics.”
Objective reality does not require or lead to reductionism. This misconception comes from the fact that an important part of science is about decomposing systems to investigate their parts. But science is also about unifying observations to create universal explanations. The alternative to reductionism is the view that when a certain level of complexity is reached, new laws emerge that cannot be described by the laws of the lower level. For example, your body is made up of cells. But even if we had perfect knowledge of how cells work, it would never describe you. Your life depends on your cells, you act through your cells, but it is impossible to understand you knowing only about your cells. Physics is therefore not sufficient to understand the world, even though everything that happens is ultimately based on physics. While there are no hard boundaries between physics, chemistry, biology and psychology, these sciences are separate disciplines because that is the only way to study the higher level rules that define them.
“My concern here is not to argue against this reductionist position, but to draw attention to a vitally important point: that these ideas do not constitute scientific knowledge; rather they represent a philosophical, in fact a metaphysical, position.”
This is indeed a vital point. For example, Newton’s laws of motion have been thoroughly tested and verified. But this established fact does not provide support for common metaphysical belief at the time in a clockwork universe, or for the physical assumption that time is the same everywhere. These notions were never experimentally verified, and have turned out to be false. We must always be careful to distinguish between verified scientific knowledge and the unverified theories and opinions of individual scientists.
When the Dalai Lama said on page 3 that Buddhism must align with “scientific analysis” he means verified knowledge, as opposed to unproven assumptions and metaphysics. As verified knowledge is rather limited in his domain of psychology, few of his fundamental beliefs are actually challenged. To his credit, he is willing to discard some of the myths that Buddhism inherited from Hinduism.
“The view that all aspects of reality can be reduced to matter and its various particles is, to my mind, as much a metaphysical position as the view that an organizing intelligence created and controls reality. The danger is that human beings may be reduced to nothing more than biological machines, the products of pure chance in the random combination of genes, with no purpose than the biological imperative of reproduction.”
A science that recognizes emergent properties knows that we are more than our cells, more than our genes, and more than our evolutionary heritage. Reductionism may be used as an excuse for nihilism, but it is curious how moral relativism, which is based on the rejection of the existence of objective reality, also leads to nihilism. Scientific method and Buddhism may both be seen as a middle way to the truth.
“According to the theory of emptiness, any belief in an objective reality grounded in the assumption of intrinsic, independent existence is untenable. All thing and events, whether material, mental, or even abstract concepts like time, are devoid of objective, independent existence. To possess such independent, intrinsic existence would imply that things and events are somehow complete unto themselves and are therefore entirely self-contained. This would mean that nothing has the capacity to interact with and exert influence on other phenomena.”
For a middle-way guy this is a hardline view. It is based on a false dichotomy playing on the word “independent”. Objects can exist independent of our observation of them without making them completely independent and isolated from everything.
Next we are told that belief in objective reality leads to “attachment, clinging, and the development of our numerous prejudices.”
The attachment issue is another false dichotomy. Some attachment is necessary to have any goals and get anything done (including meditation), while excessive attachment interferes with rational thinking. For example, the Dalai Lama seems to have an attachment to the theory of emptiness, not to mention to the independence of Tibet. The solution for attachment problems is not to wish the real world out of existence. This is like curing acne with suicide. As for prejudice, its very definition is to believe what you want to believe, rather than accept objective reality.
The denial of objective reality is not a problem for Buddhism because it also hands its students a pre-packaged purpose in life. For others, the logical conclusion is that if nothing objectively exists, you cannot really know anything. So believe anything you want, why care about anything?
The Dalai Lama does not support this kind moral relativism, if I understand this book at all. He seems to think first person introspection is ruled out by science. But if meditation actually leads to a tangible change, such as the state of mind or physiology of the meditator, or increased compassionate behavior, then this is also the realm of science. Why would the Dalia Lama invite scientists to study meditators if there was no reality to it? Again, an unnecessary restriction is being placed on science.
There is much to like about this book other than the philosophy of science it presents. Listen carefully to what the scientists tell him, as opposed to his conclusions, and remember that science can be broader than he gives it credit for.
