From pointer to individual to name
Even if you’re not a philosopher of language, I think you could still find sentences like this interesting:
WHO KNEW? It turns out I’m a pseudonym of Glenn Greenwald’s. The things you learn from blogs. Interestingly, Glenn Greenwald blogs at a site he named Amygdala, as well as at Unclaimed Territory.
That is, “I”, i.e., whoever the author of the blog is, i.e., the name of that author, is a pseudonym.
Of course, you could skip the last step if you think that pseudonym really has a meaning closer to “constructed identity” or “constructed self,” as opposed to simply “fake name”.
