The 4 Cardinal Virtues are; Prudence, Temperance,Justice, and Fortitude.
Philosophers recognize the interrelatedness of the virtues such that courage without prudence risks becoming mere foolhardiness. Aquinas found an interconnection of practical wisdom (prudentia) and moral virtue. This is frequently termed "the Unity of the Virtues." Aquinas also argued that it not only matters what a person does but how the person does it. The person must aim at a good end and also make a right choice about the means to that end. The moral virtues direct the person to aim at a good end, but to ensure that the person make the right choices about the means to a good end, one needs practical wisdom.[Aquinas.
