Seven virtues
The "Catechism of the Catholic Church" defines virtue as "a habitual and firm disposition to do the good." Traditionally, the seven Christian virtues or heavenly virtues combine the four classical cardinal virtues of prudence, justice, temperance and courage (or fortitude) with the three theological virtues of faith, hope and charity. These were adopted by the Church Fathers as the seven virtues.
Hecato of Rhodes
According to Diogenes, Hecato divided the virtues into two kinds, those founded on scientific intellectual principles (i.e. wisdom and justice), and those with no such basis (e.g., temperance and the resultant health and vigor). Like the earlier Stoics, Cleanthes and Chrysippus, Hecato also held that virtue may be taught.
