"You never know" is best possibly formalised as: _for anyone_, he or she doesn't know (cfr. "You can't teach an old dog new tricks"). I.e. the point is that while "I" carries its personhood in a blatant way, "you" is more of an 'impersonal' thing. Note, too, that Grice's dictum somewhat holds, "If you can't put it in symbols, it's not worth saying". For suppose Einstein were to propose, as indeed he did, "E =mc2". His essay, from what I recall, does NOT beging with, "I hold this to be true: E = mc2" -- which would be 'ad hominem'. I.e. To use "I" in scientific essays is considered rude. People use "we" which is thought somehow to be more polite, but still a bit too personal for me. I prefer to use "you". "In this essay, you hold that E = mc2". Note that the French use "on", which was wrongly assumed by the English to mean, "one" as in "One can't help it" ("But two perhaps can", Humpty Dumpty retorts). Illeism is the theory that for any occurrence of "I" it can be turned into a THIRD person utterance. Lichtenberg after translating Descartes's Meditations from the original French into Lichtenberg's vernacular, concluded that Descartes's dictum: "I am ----- Therefore, I think." was possibly meant to signify, by Descartes, mutatis mutandis: Lichtenberg is ---- Therefore, Lichtenberg thinks. Replacing "Lichtenberg" by "Descartes", we get the scientific point made by Grice: "if you can't put it in symbols, it's not worth saying". For surely the TRUTH of the 'cogito' extends beyond the circumlocutory use of "I" (or 'you' or 'he', for that matter). And so on.
