Abstract
Joshua Knobe's work has marshaled considerable support for the hypothesis that everyday judgments of whether an action is intentional are systematically influenced by evaluations of the action or agent. The main source of evidence for this hypothesis is a series of surveys that involve an agent either helping or harming something as a side effect. Respondents are much more likely to judge the side effect intentional if harm is involved. It is a remarkable feature of the discussion so far that it assumes without scrutiny that the substitution of one act-type for another could not, taken alone, explain the difference in responses that the two scenarios yield. This paper presents evidence, both experimental and conceptual, that it is precisely this difference that explains the asymmetry in responses. Briefly, agents who token the act-type help must fulfill certain psychological conditions that they don't have to fulfill if they are to token the act-type harm. Harming, unlike helping, does not require the ful..
