Music […] gives soul to the universe, wings to the mind, flight to the imagination, and charm and gaiety to life and to everything. ~Plato
I love music. I love listening to it. I love playing it. I love talking about it. I can be a bit snobbish about my preferences for it (but I’m working on that). But, really, music is music, and that makes it great. It can be enjoyed by people of all nations, for there is no language barrier in music. (For example, when I was in Berlin several years ago, I went to see Carmen. If you’re not familiar with that opera, it’s sung in French…which I don’t speak. Being in Berlin, the surtitles were in German…which I can’t read. Needless to say, I was clueless about the plot. But, I was still able to enjoy the music and the performance, both of which were stunning.) It brings people together for a common purpose of making or listening to something beautiful, and there is something so uniquely special in an ensemble of individuals playing together as one. It speaks to our emotions and helps us express them in ways that our words can’t. It’s food for the soul.
It’s also food for the brain. Continue reading
I’m not going to try to argue that consciousness arises from some mysterious quantum activity within the atoms making up the brain’s neurons. As a scientist, I know better. As a cognitive scientist, I know that, though it is not fully understood how consciousness arises from neural activity, consciousness does indeed arise from that neural activity. No neural activity, no consciousness—simple as that. I also know just enough about physics to know that quantum phenomena are (as I understand) limited to subatomic particles (though atoms can sometimes act like quantum particles), so there’s no way that neurons, which are composed of cells, which are composed of molecules, which are composed of atoms, could behave quantumly. No. Neurons must obey the laws of classical mechanics, not quantum mechanics.
Also, as Matthew Francis, with warrant and good reason, exhorts in this post, it is often a grievous error to apply quantum models to other mysterious phenomena, noting that, when this is done, the person has either misunderstood quantum mechanics or the other phenomenon of interest. However, his exhortation is against those who argue that quantum mechanics is what underlies these other mysterious phenomena. It was never my intention to argue that case for consciousness. As I said above, cognitive science tells us that’s not how consciousness works. So rather than argue that quantum processes give rise to consciousness, I will argue that quantum mechanics makes for an effective and compelling analogy for explaining how consciousness works. That is, perhaps thought functions not unlike a quantum particle and consciousness arises from brain function as a not wholly predictable process, similar to how quantum phenomena arise rather unpredictably from quantum particles.
