Document Summary
This sentence does have a truth-value (as it happens, the value false"): this sentence is a curse. It has no truth-value: this marginally grammatical sentence might be an instruction to police officers, in which case it does not have a truth-value. It might also be a warning to motorists, in which case it does have a truth-value: this is a bit of advice. That boxer is moving well and throwing hard punches. The argument is deductively invalid. (the boxer may have injuries that are not apparent, so we can assume that the premise is true and the conclusion is false without running into a contradiction. ) It does have considerable inductive strength: this is not an argument. It is a claim, probably a true one, that certain behavior in bridge is inadvisable: this is an argument: Either the members of the electoral college do their job or they don"t.
