There seem to be many a folk who despise the irrationality of the soul mechanism—I suppose because of the religious associations it entails—yet absolutely lap up the idea that there is some kind of pure, quintessential self trapped inside their personal shells of conflict and imperfection. They appear to regard strife, confusion, and vexing ambivalence as something too imperfect for themselves, and, therefore, something that should be exempted from their genuine identities.
Certainly, we can do without the false choice and accept that Pierpont’s true self is, in fact, homosexual, self-loathing, and confused.
The thing is, I am constituted by, among other things, all of my desires. There is no sub-set that is my "true" self. If I have a desire to have sex while wearing a rubber wetsuit, while also thinking that there is something depraved about having sex in a rubber wetsuit, while also wondering whether my judgments about what is or is not "depraved" are justifiable, then all of the above is part of me.
Normally, I may not reveal this desire - I may be ashamed of it, embarrassed for others to know of it, and so on. But if I get drunk and reveal my desire for sex in a rubber wetsuit I am indeed revealing something true about myself. In that sense, people who hear me say (positive) things about having sex in a rubber wetsuit really are learning something about me that they otherwise would not know - drunkenness can, indeed, be revealing. But it doesn't follow that my desire for sex in a rubber wetsuit is my "true" self and that my belief that sex in a rubber wetsuit is depraved, my desire not to act on my sexual desire, and my desire not even to mention it, are not my "true" self. All of these are components or aspects of the complex thing that is me.
There is still a question as to whether someone with the combination of beliefs and desires that I specified above should actually find one or more like-minded partners for the purpose of rubber-websuit sex. Is it or is not most rational for this person to do so? That may mean trying to sort out whether rubber-wetsuit sex really is "depraved", and a lot of other soul-searching.
It is not obvious that, if I have this desire for rubber-wetsuit sex, I should simply act on it. But nor is it obvious that I should simply refuse to act on the desire in accordance with my current inhibitions or concerns about it. But whatever I decide, it won't be a matter of finding my "true" self while the rest of my desires and beliefs are somehow outside of and alien to what is "truly" me. That may be one way to look at it, as a simplified model, but it's not what is really going on. All my beliefs and desires are truly me, even if some are stronger or "deeper" or less revisable than others.
