Do abstractions exist? Here we go for the 641st time… This piece is largely a response to silenceinbetween’s excellent post A Case For the Reality of Abstractions. (For brevity I will refer to the author as S going forward.) S frames the problem as such: The central tension here is that physics, as we currently understand it, operates like so: there was an initial set of conditions and laws which operate on those conditions....
In Why I am not an effective altruist, Erik Hoel criticizes the philosophical core of the EA movement. The problem with effective altruism—which is basically utilitarianism—is that it leads to repugnant conclusions (coined by Derek Parfit in Reasons and Persons): Example: strict utilitarianism would claim that a surgeon, trying to save ten patients with organ failure, should find someone in a back alley, murder them, and harvest all their organs. Example: utilitarianism would claim that there there is some number of “hiccups eliminated” that would justify feeding a little girl to sharks....
(Originally written in December 2021.) In a previous post I explored some arguments about whether we have direct access to qualia. I was trying to figure out whether there are entities within our direct experience, and whether that undermines aspects of Deutsch and Popper’s philosophy, as well as whether it has implications for which beings are conscious. After writing that post, a remark by Jake Orthwein gave me a subtle but important shift in perspective....
The idea that the hard problem can be solved with metaphysics has been gelling in my mind for quite a while now. There are three threads I’m exploring that are all landing in the same place. First, there’s Bernardo Kastrup’s work. In his theory of analytical idealism, reality is ultimately made of a single, primitive, instinctive mind, and this mind dissociates into a bunch of more complex minds (these are the individual conscious beings that we’re familiar with)....
This is an outgrowth of A first pass at David Chapman’s metarationality. In Abstract Reasoning as Emergent from Concrete Activity, David Chapman quotes a summary article about the “E-approaches” in the cognitive sciences: E-approaches propose that cognition depends on embodied engagements in the world. They rethink the alternative, ‘sandwich’ view of cognition as something pure that can be logically isolated from non-neural activity. Traditionally, cognition is imagined to occur wholly within the brain....
[The philosophical meat of this article is under the section “Current threads and questions”. Feel free to skip to that.] This tweet has had a big impact on my life: 🧵 Trying to Figure Out Where @DavidDeutschOxf's Critical Rationalism and @Meaningness's Meta-rationality Disagree (for the very small niche of people that find this interesting) — Jake Orthwein (@JakeOrthwein) April 24, 2021 When I stumbled upon it, I had spent about a year being deeply entrenched in the philosophical worldviews of critical rationalism, espoused by the physicist David Deutsch (which he had inherited from the philosopher Karl Popper)....
When I was reading The Beginning of Infinity, one of the passages that stood out to me was about contradictions (emphasis mine): Since theories can contradict each other, but there are no contradictions in reality, every problem signals that our knowledge must be flawed or inadequate. Our misconception could be about the reality we are observing or about how our perceptions are related to it, or both. (18) There are no contradictions in reality....
I recently published a substack post on consciousness and am using this to write a few extra notes that I excluded from the article for brevity. My goal with the article was to take the reader on a kind of explanatory journey, which meant that I had to take certain intellectual shortcuts and brush over some nuances. Examples: I start the piece with a materialist paradigm in which it’s “obvious” that chairs and atoms are not conscious....
How is it that we can imagine things that are logically impossible? I’ve always been a little perturbed by this. It was strange to me that we can imagine or even believe things that are logically impossible. It makes sense to me that we can imagine things that are physically impossible. Our imagination is not constrained by the laws of physics. We can imagine physical objects which don’t exist or cannot exist....
The word ‘absurd’ has always held a special place in my heart. ‘Absurd’ evokes the ridiculousness of everything around us—the serendipity of our mutual existence at this place and time, the immeasurable complexity of the cells and proteins that make up our bodies, the unfathomable size of our galaxy. The moments I’m in touch with this absurdity have always been the moments I felt most alive. I’d find myself in awe that anything exists at all, and that the things which do exist happen to form this particular conscious experience of ‘me’ and ’the world’....
