ABSTRACT
In An Essay in Aid of a Grammar of Assent, John Henry Newman claimed that nature furnishes three “main channels” for acquiring knowledge of God-“the course of the world,” “the voice of mankind,” and “our own minds,” that is, conscience. The last is “the most authoritative,” however.1 For the argument from conscience “is a proof common to all, to high and low, from earliest infancy. It is carried about in a compact form in every soul. It is ever available-it requires no learning . . . ”2 Newman’s argument from conscience is, in essence, this.
