B. Faith is a knowledge conditioned by holy affection.—The faith which apprehends God’s being and working is not opinion or imagination. It is certitude with regard to spiritual realities, upon the testimony of our rational nature and upon the testimony of God. Its only peculiarity as a cognitive act of the reason is that it is conditioned by holy affection. As the science of æsthetics is a product of reason as including a power of recognizing beauty practically inseparable from a love for beauty, and as the science of ethics is a product of reason as including a power of recognizing the morally right practically inseparable from a love for the morally right, so the science of theology is a product of reason, but of reason as including a power of recognizing God which is practically inseparable from a love for God. We here use the term “reason” to signify the mind’s whole power of knowing. Reason in this sense includes states of the sensibility, so far as they are indispensable to knowledge. We cannot know an orange by the eye alone; to the understanding of it, taste is as necessary as sight. The mathematics of sound cannot give us an understanding of music; we need also a musical ear. Logic alone cannot demonstrate the beauty of a sunset, or of a noble character; love for the beautiful and the right precedes knowledge of the beautiful and the right. Ullman draws attention to the derivation of _sapientia_, wisdom, from _sapĕre_, to taste. So we cannot know God by intellect alone; the heart must go with the intellect to make knowledge of divine things possible. “Human things,” said Pascal, “need only to be known, in order to be loved; but divine things must first be loved, in order to be known.” “This [religious] faith of the intellect,” said Kant, “is founded on the assumption of moral tempers.” If one were utterly indifferent to moral laws, the philosopher continues, even then religious truths “would be supported by strong arguments from analogy, but not by such as an obstinate, sceptical heart might not overcome.”
