The purpose of the Diagnostic is to help you identify a virtue (or habit of excellence) that you'd like to grow in, and then provide practical guidance. The organizing structure for the Diagnostic is the taxonomy of virtues presented by St. Thomas Aquinas in his Summa Theologica. What is helpful about this taxonomy is that it is comprehensive: every aspect of human experience is covered. 


Please keep in mind that this is very much a work in progress, and we welcome your feedback at
