| Abstract | Now, is the rule F(x) & x=y → F(y) valid as a general logical principle? If it is, then, by applying it to true sentences, Lois does not believe that Clark Kent is strong, and Clark Kent = Superman, we should obtain a true sentence: Lois does not believe that Superman is strong. However, the sentence Lois believes that Superman is strong is true as well, which is a contradiction. Thus, as a general logical principle, F(x) & x=y → F(y) seems to be wrong. |
