Quote of the Day

Quantum mechanics presents a view of reality in which we inhabit many worlds at once. As the political scientist Alexander Wendt has put it in Quantum Mind and Social Science, we are “walking wave functions,” which “collapse” at decisive moments, when everyone is forced to accept the same reality, but in a way that reconfigures each person’s view of how the past was and the future will be. Niels Bohr introduced the word “incommensurability,” which Thomas Kuhn popularized, to characterize the kind of “coherence” involved here. For example, Galileo could imagine living in both a geocentric and a heliocentric world, until his telescopic observations convinced him of the latter. At that moment, he started living exclusively in the heliocentric world and proceeded so much in that way that he eventually faced a Papal Inquisition.

We don’t have different perspective, we inhabit different realities | Steve Fuller » IAI TV

A summary of the article:

We tend to think we live in a shared reality, with differences in how we experience the world attributed to differences in perspective. But according to philosopher and founder of social epistemology, Steve Fuller, this is a radical mistake. Breakthroughs in neuroscience, quantum mechanics, and AI show that we don’t have different perspectives on the same reality. We inhabit different realities altogether.

I’m not complete sold on this but I’m willing to say I find very little to disagree with him on this topic. And using this framework as a model for human behavior could be very useful. I’ll have to think on this some more.

One of the first thoughts that come to mind is how gun owners versus gun grabber’s view firearms.

Gun owners tend to think of them as defensive tools used to protect innocent lives and their property. Government confiscation of firearms is viewed as enabling enslavement and/or genocide.

Gun grabbers tend think of firearms as tools of criminals to commit violent crime. Government confiscation of firearms is viewed as reducing violent crime and even reducing the number of criminals. There is no downside to gun confiscation if the ignorant, stupid, deplorables would just turn their guns in without a fuss.

These two groups live in irreconcilable realities and live their lives immersed in them without significant discomfort or desire to challenge their beliefs.
