As for human knowledge concerning the mind, it has two parts, one inquiring of the substance or nature of the soul, and the other of its faculties or functions. I believe that the first of these may be more soundly inquired than it has been, yet I hold that in the end it must be bounded by religion. It has two appendices, concerning divination and fascination; these have rather vapoured forth fables than kindled truth. The knowledge respecting the faculties of the mind is of two kinds, the one respecting understanding and reason, and the other respecting will, appetite, and affection, the imagination being active in both provinces. The intellectual arts are four--inquiry or invention, examination or judgment, custody or memory, and elocution or tradition; and these are severally divided into various sciences and arts. The knowledge of the appetite and will, or moral philosophy, leading to the culture and regiment of the mind, is very deficient. Civil knowledge has three parts--conversation, negotiation, and government--since man seeks in society comfort, use, and protection. The first of these is well laboured, the second and third are deficient. Thus we conclude human philosophy, and turn to the sacred and inspired divinity, the port of all men's labours and peregrinations. Sacred theology, or divinity, is grounded only upon the word and oracle of God, and not upon the light of Nature. Herein there has not been sufficiently inquired the true limits and use of reason in spiritual things. Exposition of Scriptures, on the other hand, is not deficient. Divinity has four main branches--faith, manners, liturgy, and government--in which I can find no ground vacant and unsown, so diligent have men been, either in sowing of seed or tares. * * * * * GEORGE BERKELEY PRINCIPLES OF HUMAN KNOWLEDGE
