Consciousness Is Just a Feeling

Steve Paulson in Nautilus:

When he was a boy, Mark Solms obsessed over big existential questions. What happens when I die? What makes me who I am? He went on to study neuroscience but soon discovered that neuropsychology had no patience for such open-ended questions about the psyche. So Solms did something unheard of for a budding scientist. He reclaimed Freud as a founding father of neuroscience and launched a new field, neuropsychoanalysis. I reached Solms in Cape Town, South Africa, where he’s stayed during the COVID-19 lockdown. We talked about the brain-mind problem, the biases of neuropsychology and how a family trauma shaped the course of his life.

There are huge debates about the science of consciousness. Explaining the causal connection between brain and mind is one of the most difficult problems in all of science. On the one hand, there are the neurons and synaptic connections in the brain. And then there’s the immaterial world of thinking and feeling. It seems like they exist in two entirely separate domains. How do you approach this problem?

Subjective experience—consciousness—surely is part of nature because we are embodied creatures and we are experiencing subjects. So there are two ways in which you can look on the great problem you’ve just mentioned. You can either say it’s impossibly difficult to imagine how the physical organ becomes the experiencing subject, so they must belong to two different universes and therefore, the subjective experience is incomprehensible and outside of science. But it’s very hard for me to accept a view like that. The alternative is that it must somehow be possible to bridge that divide.

The major point of contention is whether consciousness can be reduced to the laws of physics or biology. The philosopher David Chalmers has speculated that consciousness is a fundamental property of nature that’s not reducible to any laws of nature.

I accept that, except for the word “fundamental.” I argue that consciousness is a property of nature, but it’s not a fundamental property. It’s quite easy to argue that there was a big bang very long ago and long after that, there was an emergence of life. If Chalmers’ view is that consciousness is a fundamental property of the universe, it must have preceded even the emergence of life. I know there are people who believe that. But as a scientist, when you look at the weight of the evidence, it’s just so much less plausible that there was already some sort of elementary form of consciousness even at the moment of the Big Bang. That’s basically the same as the idea of God. It’s not really grappling with the problem.
