My name is Ryan Autry, and I’m a building-level IT Specialist / Sysadmin for a large Texas school district. One of my favorite pastimes is to figure out why things work, and why things are the way they are, which I suspect is why I took a liking to my profession in the first place.
In my free time I often think about topics not related to my work, including philosophy, theory of mind, programming, physics, and occasionally politics. A little while ago I realized I liked my ideas, and so I decided to write them down. The only problem is that I’ve never been good at journaling, because with nobody to read the words I don’t see much point in putting them down on the page.
To fix this, I’ve decided to put my thoughts out as essays, publishing them to my site, then crossposting them to a few other places. It’s my hope that my ideas have an impact, and if they don’t, my hope is that it’s due to the ideas being disproven rather than ignored.
After arguing on TheMotte for a few days and thinking it through, I have an answer.
I made a mistake in my description of the derivation. Step eight’s assertion, “By logic, one concludes that those things are real, as things which are not real cannot affect things which are,” is both unnecessary and poorly defined. The same goes for step eleven’s assertion that one “must” assume similar bodies must be the embodiments of other selves.
First let’s clean up the question of “what is real”. What really matters to Cogitism is that you are a “self”, an observer-actor who can think. Anything that the self doesn’t control (even the “mind”, including side-effects of neurochemistry, such as hallucinations, intrusive thoughts, emotions, etc) are considered “external” to the core self.
Whether these external things are metaphysically “real” in any sense doesn’t really matter; what matters is that they are outside the domain of things the self controls directly, and they affect the self’s cohesion. Because they can affect the self, and we’ve assigned value to the self, they are ethically significant.
Having said that, we can continue up the chain: in the domain of the things the self doesn’t control directly, the self can observe bodies similar to its own. We don’t need to assert that these are embodiments of other real “selves”, we just need to establish that denying that they have selves undermines the self enough to be ethically dangerous.
We established the existence of the self in the current moment through logic and observation. Whether we even existed a moment ago or will exist a moment from now is based on very high confidence, but not certainty. We already know that we can’t be truly certain about anything except that the self exists in the current moment.
We’ve used the same tools of high-confidence logic and observation all the way up the chain (with the sole exception of the one “ought” out of which the rest of the ethics grow), so demanding an impossibly high threshold of confidence when it comes to other selves is inconsistent, and calls into question the logic and observation we use for literally any thinking outside the self at all.
If we demanded certainty for more basic things, like whether we’ll exist a second from now, that would undermine the entire exercise of thinking about anything, which would mean there’s no point in trying to argue ethics in the first place. It’s completely incoherent to call these tools into question while still engaging in argument; Thus, denying other beings’ selfhood is incoherent and therefore unethical under this framework.
I’m very curious to hear what your issue is with step 2. If there’s a problem I’d like to try and fix it.
