2. The term pro tanto reason was introduced into modern moral philosophy by Shelly Kagan, who writes: "A pro tanto reason has genuine weight, but nonetheless may be outweighed by other considerations. Thus, calling a reason a pro tanto reason is to be distinguished from calling it a prima facie reason, which I take to involve an epistemological qualification: a prima facie reason appears to be a reason, but may actually not be a reason at all, or may not have weight in all cases it appears to. In contrast a pro tanto reason is a genuine reason - with actual weight - but it may not be a decisive one in actual cases." The limits of morality,1989
