Ethicist: Marital vows often contain the promise to love "until death do us part. " If "love" here refers to a feeling, then this promise makes no sense, for feelings are not within one' s control, and a promise to do something not within one' s control makes no sense. Thus, no one -- including those making marital vows -- should take "love" in this context to be referring to feelings. The ethicist's conclusion follows logically if which one of the following is assumed? ['People should not make promises to do something that is not within their control.', 'Promises should not be interpreted in such a way that they make no sense.', 'Promises that cannot be kept do not make any sense.', '"Love" can legitimately be taken to refer to something other than feelings.']
