Many contributors to military ethics from diverse locations and philosophical perspectives maintain that virtues are central to martial theory and practice. Yet several contemporary philosophers and psychologists have recently challenged the empirical adequacy of this perspective.

In (...) this paper, I assess the merit of this critique and consider some implications of my assessment for military practitioners and theorists. (shrink)
