There are two different opinions among philosophers concerning the passions of the mind: the Stoics do not allow that any passion is incident to the wise man; the Peripatetics affirm that they are incident to the wise man but in a moderate degree and subject to reason; as, for example, when mercy is shewn in such a manner that justice is preserved. But in the Christian rule we do not enquire whether the mind is first affected with anger or with sorrow, but whence.
