Abstract

Douglas Langston’s book is an important contribution to the literature on ethics since it re-establishes the importance of “conscience” as a useful tool in ethical theorizing. Contemporary ethicists criticize conscience and outwardly reject any use of the concept to develop an adequate ethical theory. Even virtue theorists refrain from talking much about conscience as an important analytic tool. Langston believes that this is an important omission that must be rethought for the purposes of developing an effective ethical theory that is applicable to human beings in their search for living fulfilled lives. Throughout the book, Langston examines some of the main reasons why conscience has been abandoned as a useful analytic tool in ethical theorizing by contemporary theorists. One reason that Langston cites is that, after the seventeenth century, philosophers regarded conscience as a faculty that was distinct from the intellect, will, and memory. It may have been better if some of these theorists postulated some type of interaction between these faculties instead of arguing that each of them should be kept separate and distinct. Another reason may be the long identification of conscience with some set of rules for behaviour. This reduces conscience to a set of observable rules that are followed by an individual. It extricates the person from the action and reduces the responsibility that an individual should feel when acting in a particular situation. In addition, when one removes moral reasoning from conscience, its only function is to make one feel uncomfortable when one refrains from doing the right thing. This is insufficient in building an ethical theory or in living a moral life. What is needed is a more positive view of the notion of conscience, which is possible when one regards it as more than a faculty whose judgements are infallible. One of Langston’s themes in the book is that it is possible to develop a positive view of conscience that can also be used as an analytic tool in developing an effective ethical theory.
