The author examines an argument against the claim some suicides may be morally legitimate. This argument appeals to a putative moral principle that it is never licit to assault an innocent human life. Related arguments in St. Augustine & St. Thomas are considered. Two possible senses of “innocent” are then explored. Mavrodes argues that in one sense the putative moral principle is very implausible & in neither sense is it true that all suicides assault an innocent life. Therefore, this line of argument fails to establish the desired universal prohibition of suicide. (61 notes)
