The chapter presents, describes and illustrates the functions that philosophy can perform when applied to public administration (PA). The functions that philosophy applied to a PA problem or theme can perform include: an enlightening function; a critical function; a gap filling function; an integrative function; and a normative function—one or more such functions in a combined way. The discussion of a number of scientific articles in the field of PA that employ and deploy a philosophical perspective as a core part of the argument is used in an illustrative way to highlight the actual performance of these functions in published scholarly work. This chapter articulates the approach in connecting philosophy and PA that we qualify as ‘philosophy for PA’. The chapter finally expands on the possibility of combining a range of philosophies to address given PA problems as well as, more ambitiously, to match fields of philosophy with thematic areas of PA as ways of more closely interconnecting philosophy and PA.
