Practical Friendship brings insights together from ancient and contemporary philosophy, theology, psychology and sociology to identify what good friendship means and how we can live it.

Based on the analysis it proposes we adopt a role based view of friendship, that also can be used to analyse loneliness. Based on research and anecdotal evidence the book compiles a range of recommendations on how to maintain our friendships in good repair and how to foster friendship in old age.

The book addresses an audience of professionals working to fight loneliness in our society as well as lay people wanting to reflect on how to improve the friendships in their lives. Additional sections are addressed at researchers in sociology and psychology who want to expand their understanding of friendship in order to tune their research to generate insight for loneliness-support.
