Mind vs. Brain

March 27, 2013

The first issue of the new publication, Mindfulness, features a column by Sharon Begley having the same title as this blog post. Her article motivated this current post. Scientists seem to be reluctant to talk about mind in a scientific context. Cartesian dualism is no longer in vogue. Neuroscience is the new kid on the block capturing fascinating images of the brain in action. The brain constitutes solid science; the mind remains somewhat questionable. There is a consensus that the mind is an emergent phenomenon emerging from the brain. However, the status of the mind remains questionable.

What is overlooked is that the neuroscience would be meaningless absent the mind. Images could be collected of the brain in action, but there would be no way of knowing what they mean. The typical brain imaging paradigm involves instructing people to do something and see what images emerge. That something is resident in the minds of both the experimental participants and the scientists doing the experiment. Otherwise the entire exercise would be meaningless.

The law of parsimony plays an important role in science. All things being equal, the simplest explanation is the best. So the simplest explanation is that the brain engenders activity which we interpret as the mind. This explanation assumes that the mind is epiphenomenal. In other words, it serves as a movie we passively observe and experience as mind. It is important to realize that parsimony can be overdone. The notion is that the explanation that should be chosen is the one that is simplest that still explains the most.

The first question to ask about the mind, is why is it there? Even if it is an epiphenomenon, why does it exist? Evolutionary explanations like to include reasons why things involved. So one should think that if the mind exists, there should be a reason for it. In my view the reason is for it to act on the brain. The entire notion of mindfulness is that the mind can act upon the brain, and there is ample evidence to accept this notion. Moreover, there is a pragmatic argument. Consider two individuals. One is a practitioner of mindfulness and engages in practices to control her emotions and to improve her cognitive function. The other believes that her mind is an epiphenomenon and that her brain will determine what happens. Which one do you think will be happier and more successful?
