In this short critical analysis, the author examines the recent argument by Moen in his article ‘Is Prostitution Harmful?' In highlighting why prostitution does not cause harm to either member involved in the act, Moen argues that prostitution is not an ethical concern. However, while Moen is able to clearly challenge contemporary objections to prostitution, the author of this review will suggest that Moen's argument is itself incomplete as it does not address essential key ontological issues. This critical analysis will (...) briefly suggest why this omission weakens Moen's argument. Finally, it will conclude with examining why prostitution differs substantially from other professions through the type of harm that it causes to the moral agents involved. (shrink)
