These are what are termed the four Cardinal Virtues : Temperance, Fortitude, Prudence and Justice. Derived initially from Plato's Protagoras 330b, and found in Thomas Aquinas' Summa Theologica II(I).61), the term "cardinal" comes from the Latin cardo or hinge; they are hinges upon which the door of the moral life swings. The Christian Graces are Faith, Hope and Charity. The Masonic Virtues are Brotherly Love, Relief and Truth.
