AbstractMoral reflection and deliberation on both deception and manipulation is hindered by lack of agreement on the precise meanings of these concepts. Specifically, there is disagreement on how to understand their relation vis-à-vis each other. Curiously, according to one prominent view, all deceptions are instances of manipulations, while according to another, all manipulations are instances of deceptions. This paper makes that implicit disagreement explicit, and argues that both views are untenable. It concludes that deception and manipulation partially overlap, and takes further steps in delineating the border between these concepts. The paper ends with the conclusion that moral judgments regarding either manipulation or deception cannot be transferred wholesale from the one concept to the other just by virtue of the relations between the concepts.
