Could it be a coincidence that two founding fathers of modern day computing, independently from each other, are both coming with theories of consciousness that are idealist in nature? Or does a deep understanding of what computation is—and what it is not—inevitably lead away from physicalist ideas on consciousness?

Essentia Foundation’s Hans Busstra visited Vienna to attend a conference on the foundations of quantum mechanics, and interview physicists on the metaphysical implications of quantum mechanics. In this essay, he argues that what is called ‘experimental metaphysics’ might be at the heart of future progress in physics, and that philosophy and physics are moving closer together.

Once an enthusiastic Idealist in the tradition of Arthur Schopenhauer, the later Friedrich Nietzsche broke from Schopenhauer’s philosophy with a vengeance. Adebambo Adedire argues that this shift had more to do with Nietzsche’s later rejection of the metaphysical project itself, than with the particulars of Schopenhauer’s Idealism. For Nietzsche was to eventually consider the goal of understanding the nature of reality both impossible and inherently demeaning to the human condition. Yet, we ask, can a thinking human being ever stop wondering about what reality, and the self within it, ultimately are? Even if we, as primates, cannot arrive at the ultimate metaphysical answers, aren’t we correct in aspiring to overcome our own metaphysical mistakes and delusions?

Jonathan Dinsmore proposes applying the same cautious inferential reasoning used in the scientific method to developing metaphysical beliefs based on first-person experience. This may open the door to a form of spirituality that, although still grounded in personal insight and, therefore, not objective in a strict scientific sense, is nonetheless based on the form of disciplined thinking that has made science so successful.

Hans Busstra sat down with John Vervaeke to discuss the meaning crisis, the Zombie myth we’re in, and how it all relates to what Vervaeke calls “rabbit hole metaphysics”: the conspiratorial, outlandish and often absurd ideas people start believing in, in search of meaning. A characteristic of rabbit hole types of metaphysics is that they have a ‘thick’ description of reality: a constellation of ungrounded assumptions build up to a ‘once you get this, there’s no way back’ narrative, which repeats itself in online echo-chambers.

The structures of our language, which function as directly accessible carriers of meaning, reveal remarkable parallels to physical systems—particularly quantum systems—which can therefore be regarded as carriers of meaning as well. This profound interconnectedness of language, thought and reality challenge our conventional understanding of what is going on, argues Dr. Sachs. His insightful observations reveal surprising ways to make sense of the paradoxes of quantum mechanics along linguistic—and therefore thought-like—lines. Though involved, we highly recommend that you give this essay a careful read, as it is surely worth the effort.
