Every one ought to provide food and raiment for his body: this must come first, yet for the purpose that a sound mind maybe in a sound body. Every one ought also to provide its food for his mind; that is, he ought to furnish it with the things belonging to intelligence and wisdom, so that it may be fitted thereby to be of use to his fellow-citizens, to human society, to his country, to the Church, and thus to the Lord. He who does so, takes care of his wellbeing to eternity.

He who looks upon himself as his neighbour in the first place, is like him who regards the foundation, and not the house or habitation, as the end; when yet habitation is the first and ultimate end: and the house together with the foundation, is only a means towards the end.
