Sin, Philosophical.

Cyclopedia of Biblical, Theological and Ecclesiastical Literature

Philosophical sins, in opposition to theological, according to the Jesuits, are those in which a man at the time of committing them has not God and his law before his mind. He, therefore, without thinking of God, transgresses natural or revealed law. These sins the Jesuits held to be venial; that is, such as do not draw after them a loss of divine grace, and do not deserve eternal, but only temporal, punishment.
