Practical Piety and Conscientiousness

Though etymologically similar, 'conscience' and 'conscientious' are rarely taken as interchangeable.  The former usually connotes a motivation, often interpreted as supernatural, to pursue one course of action, in opposition to another.  In contrast, the latter means, while also a motivation, one directed to a manner of conducting oneself.  Now, though 'conscientious' might generally not entail an origin that is supernatural, it can still involve respect for its object, as is often exhibited in skilled activity.  Thus, as more specific to Praxis than is Conscience, Conscientiousness is perhaps an even better example of Practical Piety
