In Galen Strawson's book, "Things That Bother Me," he makes an interesting distinction between people who feel a sense of continuity about themselves during their lifetime (endurants) and people who feel that they're being constituted anew as their life unfolds (transients).
There's a lot to say about this.
For now, the hour is late, I've been working on getting new iPhone 14's up and running for my wife and I today/tonight, so I'm simply going to share how Strawson defines "endurants" and "transients." He says he's a strong transient, while most people are endurants. Me, I kind of split the difference.
To take this further, it helps to distinguish between one's sense of oneself as a living embodied human being, a human being considered as a whole, and one's sense of oneself as an inner mental entity or "self" of some sort -- I'll call this one's "self-experience."
When Henry James says of one of his early books "I think of... the masterpiece in question... as the work of quite another person than myself... a rich... relation, say, who... suffers me still to claim a shy fourth cousinship," he has no doubt that he's the same human being as the author of the book, but he doesn't feel he's the same self or person as the author of the book.
This feeling is familiar to most of us: one of the most important ways in which people tend to think of themselves (wholly independently of any religious belief they may have) is as things whose conditions of persistence aren't obviously or automatically the same as the conditions of persistence of a human being considered as a whole.
Petrarch, Proust, Parfit and thousands of others have given this idea vivid expression. I'm going to take its viability for granted and set up another distinction in terms of it: a distinction between "transient" and "enduring" self-experience. (In the past I've called these forms of self-experience "episodic" and "diachronic.")
The core form of endurant self-experience is simply that one naturally figures oneself, considered as a self, as something that was there in the (further) past and will be there in the (further) future -- something that has relatively long-term temporal continuity, something that persists over a long stretch of time, perhaps for life (the word "further" is intentionally indefinite). I take it that many people are naturally endurers and that many who endurers are also narrative.
If one is transient, by contrast, if one is a transient, one doesn't figure oneself, considered as a self, as something that was there in the (further) past and will be there in the (further) future, although one is perfectly well aware that one has long-term continuity considered as a whole human being.
