Science finds it hard to decipher the mysteries of the mind largely because we lack efficient tools. Many people, including many scientists, tend to confuse the mind with the brain, but they are really very different things. The brain is a material network of neurons, synapses and biochemicals. The mind is a flow of subjective experiences, such as pain, pleasure, anger and love. Biologists assume that the brain somehow produces the mind, and that biochemical reactions in billions of neurons somehow produce experiences such as pain and love. However, so far we have absolutely no explanation for how the mind emerges from the brain. How come when billions of neurons are firing electrical signals in a particular pattern, I feel pain, and when the neurons fire in a different pattern, I feel love? We haven’t got a clue. Hence even if the mind indeed emerges from the brain, at least for now studying the mind is a different undertaking than studying the brain.
Brain research is progressing in leaps and bounds thanks to the help of microscopes, brain scanners and powerful computers. But we cannot see the mind through a microscope or a brain scanner. These devices enable us to detect biochemical and electrical activities in the brain, but do not give us any access to the subjective experiences associated with these activities. As of 2018, the only mind I can access directly is my own. If I want to know what other sentient beings are experiencing, I can do so only on the basis of second-hand reports, which naturally suffer from numerous distortions and limitations.
We could no doubt collect many second-hand reports from various people, and use statistics to identify recurring patterns. Such methods have enabled psychologists and brain scientists not only to gain a much better understanding of the mind, but also to improve and even save the lives of millions. However, it is hard to go beyond a certain point using only second-hand reports. In science, when you investigate a particular phenomenon, it is best to observe it directly. Anthropologists, for example, make extensive use of secondary sources, but if you really want to understand Samoan culture, sooner or later you will have to pack your bags and visit Samoa.
Of course visiting isn’t enough. A blog written by a backpacker travelling through Samoa would not be considered a scientific anthropological study, because most backpackers lack the necessary tools and training. Their observations are too random and biased. To become trustworthy anthropologists, we must learn how to observe human cultures in a methodical and objective manner, free from preconceptions and prejudices. That’s what you study at the department of anthropology, and that’s what enabled anthropologists to play such a vital role in bridging gaps between different cultures.
The scientific study of mind seldom follows this anthropological model. Whereas anthropologists often report their visits to distant islands and mysterious countries, scholars of consciousness rarely undertake such personal journeys to the realms of mind. For the only mind I can directly observe is my own, and no matter how difficult it is to observe Samoan culture without bias and prejudice, it is even harder to observe my own mind objectively. After more than a century of hard work, anthropologists today have at their disposal powerful procedures for objective observation. In contrast, whereas mind scholars developed many tools for collecting and analysing second-hand reports, when it comes to observing our own minds we have barely scratched the surface.
In the absence of modern methods for direct mind observation, we might try out some of the tools developed by premodern cultures. Several ancient cultures devoted a lot of attention to the study of mind, and they relied not on collecting second-hand reports, but on training people to observe their own minds systematically. The methods they developed are bunched together under the generic term ‘meditation’. Today this term is often associated with religion and mysticism, but in principle meditation is any method for direct observation of one’s own mind. Many religions indeed made extensive use of various meditation techniques, but this doesn’t mean meditation is necessarily religious. Many religions have also made extensive use of books, yet that doesn’t mean using books is a religious practice.
Over the millennia humans have developed hundreds of meditation techniques, which differ in their principles and effectiveness. I have had personal experience with only one technique – Vipassana – so it is the only one about which I can talk with any authority. Like a number of other meditation techniques, Vipassana is said to have been discovered in ancient India by the Buddha. Over the centuries numerous theories and stories have been ascribed to the Buddha, often without any supporting evidence. But you need not believe any of them in order to meditate. The teacher from whom I have learned Vipassana, Goenka, was a very practical kind of guide. He repeatedly instructed students that when they observe the mind they must put aside all second-hand descriptions, religious dogmas and philosophical conjectures, and focus on their own experience and on whatever reality they actually encounter. Every day numerous students would come to his room to seek guidance and ask questions. At the entrance to the room a sign said: ‘Please avoid theoretical and philosophical discussions, and focus your questions on matters related to your actual practice.’
