Pascal: “Nature confounds the Pyrrhonist, and Reason confounds the Dogmatist. We have an incapacity of demonstration, which the former cannot overcome; we have a conception of truth which the latter cannot disturb.” “There is no Unbelief! Whoever says. ‘To-morrow,’ ‘The Unknown,’ ‘The Future,’ trusts that Power alone. Nor dares disown.” Jones, Robert Browning, 314—“We cannot indeed prove God as the conclusion of a syllogism, for he is the primary hypothesis of all proof.” Robert Browning, Hohenstiel-Schwangau: “I know that he is there, as I am here, By the same proof, which seems no proof at all, It so exceeds familiar forms of proof”; Paracelsus, 27—“To know Rather consists in opening out a way Whence the imprisoned splendor may escape Than in effecting entrance for a light Supposed to be without.” Tennyson, Holy Grail: “Let visions of the night or day Come as they will, and many a time they come.... In moments when he feels he cannot die, And knows himself no vision to himself, Nor the high God a vision, nor that One Who rose again”; The Ancient Sage, 548—“Thou canst not prove the Nameless, O my son! Nor canst thou prove the world thou movest in. Thou canst not prove that thou art body alone, Nor canst Thou prove that thou art spirit alone, Nor canst thou prove that thou art both in one. Thou canst not prove that thou art immortal, no, Nor yet that thou art mortal. Nay, my son, thou canst not prove that I, who speak with thee, Am not thyself in converse with thyself. For nothing worthy proving can be proven, Nor yet disproven: Wherefore be thou wise, Cleave ever to the sunnier side of doubt, And cling to Faith beyond the forms of Faith.” III. Other Supposed Sources of our Idea of God’s Existence. Our proof that the idea of God’s existence is a rational intuition will not be complete, until we show that attempts to account in other ways for the origin of the idea are insufficient, and require as their presupposition the very intuition which they would supplant or reduce to a secondary place. We claim that it cannot be derived from any other source than an original cognitive power of the mind. 1. Not from external revelation,—whether communicated (_a_) through the Scriptures, or (_b_)through tradition; for, unless man had from another source a previous knowledge of the existence of a God from whom such a revelation might come, the revelation itself could have no authority for him.
