Discretion in Professional Practice and in Engineering Ethics

There is an ongoing investigation by scholars of ethics and economics into whether human decision making and the resultant acts should be guided by rules and procedures or by judgment and discretion. Although each of these modes offers advantages and disadvantages to decision makers, they are by no means neutral in their effect on professional development. The paper presents an in-depth view of discretionary decisions using an Aristotelian-Thomistic framework. This is the first of the series of papers which focus on the application of realistic philosophical principles to ethical professional behaviour and decision making in daily practice. Results indicate that classical philosophical theories which use virtues and truth as indispensable components still may give rise to desirable and moral conduct among individuals who apply them.
