Summum bonum
（重定向自Sovereign Good）
Summum bonum is a Latin expression meaning "the highest good", which was introduced by Cicero, to correspond to the Idea of the Good in ancient Greek philosophy. The summum bonum is generally thought of as being an end in itself, and at the same time containing all other goods. The term was used in medieval philosophy and in Kantianism, to describe the ultimate importance, the singular and overriding end which human beings ought to pursue. In the Thomist synthesis of Aristotelianism and Christianity, the highest good is usually defined as the life of the righteous and/or the life led in communion with God and according to God's precepts.
