Let’s assume that since it wasn’t postulated the statement is: “It will rain tonight(anywhere on the planet)” The fact that the truth value is dependent on contingent factors does not mean it isn’t a boolean expression. How I understand it, what an expression needs in order to be boolean is for it to be possible to evaluate its truth value as either true or false, indifferent of the time when the statement’s content is positioned - past, present or future. Therefore a statement like: “The cat will be dead in 2022” is boolean, even though we cannot evaluate the truth value as of yet, in 2021.
this is not a question, because for some people cats are female dogs, for others it has nothing to do with gender, so it is an opinion based statement, it cannot be verified as true or false. can anyone pls explain?? thanks
