Abstract
The role of hypothetical acts, as opposed to actual acts, has been neglected in understanding the nature of what is required by the Respect for Persons formulation of the Categorical Imperative in concrete moral relations between persons. This had led to a failure to understand fully the way and the extent to which the Categorical Imperative may be present in all such relations with others as encapsulated in an appropriate attitude towards others that may refer to hypothetical acts, as well as actual acts. The result is an underestimation of the direct relevance and moral efficacy of the Categorical Imperative.
