From such an introduction, as Devitt (1981a) and Donnellan (1974) point out, causal historical chains begin spreading into the future just as if the name had been bestowed on an actual individual. So reference or "reference" to nonexistents is by causalhistorical chain, but the chain's first link is the naming event itself rather than any putative doings of the nonexistent bearer.9 Objection 2 Evans (1973) points out that names can change their reference unbeknownst, through mishap or error, but the CausalHistorical Theory as presented so far cannot allow for that. According to Evans,10 the name "Madagascar" originally named, not the great African island, but a portion of the mainland; the change was ultimately due to a misunderstanding of Marco Polo's. Or: Two babies are born, and their mothers bestow names upon them. A nurse inadvertently switches them and the error is never discovered. It
body? This is the more neglected question. It is also a bigger problem, as you can't x it by slamming pills or potions. Based on a review of published studies, I formed three hypotheses related to my selenium deficiency: 1. Even though I consumed large quantities of supposedly selenium-rich animal foods, like beef (seven ounces satisfies the daily USRDA), the animals grazed on grass from selenium-depleted soil. 2. Going in and out of ketosis had created a selenium deficiency. Unbeknownst to me, long- term ketogenic dieting has been associated with selenium deficiency. This was a real lightbulb moment. 3. Selenium protects against mercury by binding to it. Elevated blood mercury levels, which I tested positive for, could therefore also contribute to selenium deficiency. Once I had a few plausible explanations, it was time to test corrective actions: Corrective action #1: I began to consume three Brazil nuts at breakfast and three Brazil nuts at bedtime
