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.

(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.
