I’ve seen two flavors of self-skepticism, by which I mean the position that the self isn’t real. I’ll call them the Eastern/Buddhist argument and the Western/materialist argument. I’ve always felt that self-skepticism philosophies are problematic for a number of reasons, but there is this one reason that I want to say is shared by both the above arguments.
1) The Eastern/Buddhist argument: Nothing is permanent. Therefore, the self is not permanent. What we call the ‘self’ is actually a series and mixture of experiences, internal and external, that are constantly undergoing change. Therefore, it is, like a flowing river, never the same one twice. As soon as you think you’ve identified yourself, it no longer exists.
2) The Western/Materialist argument: The self is a psychological product of the brain. Neuro-chemical events somehow manage to give us the impression that we are a self, but this, like all other mental content, is an illusion, a narrative the brain is telling itself. One might think of it as similar to value in that it is not something objectively and independently real, but subjective and totally dependent on us in order to exist, if it exists at all. Thus, the self is not really objectively real, but more of an “apparition” that the brain fabricates and convinces itself of.
The one problem that both of these suffer from, IMO, is that if you’re going to say this of the self, you have to say it of pretty much everything.
In the case of 1), the argument is the same old traditional argument of the identity of things (first proposed by Plutarch about the ship of Theseus). If a thing is constantly undergoing change, as is the nature of real things everywhere, little by little, piece by piece over time, then nothing is ever absolutely one thing or another for more than an instant. If on this basis, the self doesn’t exist, then nothing does.
In the case of 2), the arguments seems to be: if it’s mental, it’s unreal. But I’m hard pressed to think of a single thing that isn’t mental–at least, in the sense that if I can give such an example, I have no way of doing so except by presenting my mental construct of it (whether it be a thought, sensory object, memory, an emotion, etc.). Anything I purport to be really “out there” must, by that token, be “in here” (for otherwise, I couldn’t purport it at all). Yes, this is idealism 101, but it is unescapable, and furthermore is inescapable because of the Western/Materialist argument–that is, if the self is unreal because the only way we are acquainted with it is via the brain’s production of our inner sense of selfhood, then so too is anything we are acquainted with via the brain’s production of our inner sense of it (where sensory perception, being “mental”, is here considered “inner”). The entire world is therefore unreal–or at least, anything we want to offer up as an example of something real (for that entails the brain producing it in consciousness first).
Now here’s something a bit more positive on the self, and closer to common sense: going back to the ship of Theseus argument, what the argument comes down to is the fact that nothing is ever “fixed”–everything is constantly undergoing change. This is even true of a rock. A rock just sitting there apparently not doing anything is still changing. You have to look down to the microscopic scale to see it, and when you do, what you see are electrons buzzing around a nucleus (or, more accurately, forming a ‘cloud’). Therefore, even the rock is never really ‘still’. But the catch here is that these atoms and molecules are always reacquiring their prior states. That is to say, they are repeatedly coming back to the same state they were once in, much like the seasons, though going through flux, always come back to the same ones, or the planets always coming back after making a full revolution around the Sun. What this means is that on a much higher scale, the scale of the rock (or the solar system, or the years as they go by), what you get is a kind of “steady buzz”–that is, an apparent stillness, a constant. The rock seems to be one unchanging thing over a long stretch of time because of this perpetual reacquiring of prior states at the microscopic level.
Change need not mean never being the same thing twice.
Now what in the self might fit this formula? What is it in the constituents of our minds that might be considered to reacquire the same states over and over again? Well, lots of things: our memories, our identifications with our names, the particular face we see in the mirror, our beliefs, our friends and family, our values and attitudes, our tendencies, characteristics, strengths and weaknesses, our sensitivities and reactions to things, our belongings, our writings and other creations, and so on and so forth. All these things recur with a certain regularity–maybe not like clockwork, but enough so such that, if we were to step back from ourselves and our lives, looking at ourselves from the scope of our entire life span, we might just see a kind of “steady buzz”, a fuzzy semblance of what we might call our ‘selves’.
Of course, I don’t think what we’d see is an absolutely unchanging constant at this level–as much as we are constantly changing in the moment, we are also slowly changing through time–a once vibrant and energetic young man might one day turn into a frail and near-lifeless old man–but this just proves the point: it proves that if there is this slow change that occurs on the scale of our entire life span, then there must be some kind of “constant” (or an approximation thereof) at smaller scales. It would be like watching a computer monitor slowly change from red to orange to yellow over the course of 5 minutes or so. If this steady change does indeed occur, then there had to have been smaller intervals (say on the order of a few seconds or so) where the rate of change of the color was negligible or unnoticeable, and therefore could be called “constant”. This “constant”, as it applies to the self, is still the “steady buzz” that is just the “gloss” of all the more detailed and variegated elements of our psychology, which I still maintain is ever changing every second, but I still say they always come back to reacquire their prior states, and it is on this that the “steady buzz”, which is a rough basis for the identity of the self, rests. It may just be an abstraction–not a material object, or even an immaterial/metaphysical one–but as such it suffices as an adequate definition of ‘self’ as far as I’m concerned, and so we don’t have to say the self doesn’t exist.
