Professor Hartley' s new book on moral philosophy contains numerous passages that can be found verbatim in an earlier published work by Hartley' s colleague, Professor Lawrence. Ttherefore, in view of the fact that these passages were unattributed in Hartley' s book, Hartley has been dishonest in not acknowledging the intellectual debt owed to Lawrence.
The assumption that Lawrence did not get the ideas in the passages in question or did not get their formulations originally from Hartley is an assumption on which the argument is based.
