mind that held it; as the intellectual life evoked by many of the erroneous theories and exploded hypotheses of the past has been great. But no error could do so permanently. No illusion could survive as an educative and elevating power over humanity; and no alleged instinct could sustain its claim, and vindicate its presumptive title, if it could not stand the test we mention. A theoretic error is seen to be such when we attempt to reduce it to practice; as a hidden crack or fissure in a metal becomes visible when a strain is applied, or the folly of an ideal Utopia is seen in the actual life of a mixed commonwealth. Many of those scientific guesses which have served as good provisional hypotheses, have been abandoned in the actual working of them out, and so the flaw that lurks within an alleged intuition, (if there be a flaw) will become apparent when we try to apply it in actual life, and take it as a regulative principle in action. Thus, take the belief in the Divine existence, attested, as we affirm, by intuition, and apply it in the act of worship or adoration. Does that belief (which fulfils the conditions of our previous tests,--for it appears everywhere and clings tenaciously to man, and comes into collision with no other normal tendency of our nature, or defrauds any instinct of its due) does it elevate the nature of him who holds it? The reply of history is conclusive, and its attestation is abundantly clear. The power of the theistic faith over the rest of human nature is such that it has quickened the other faculties into a more vigorous life. Its moral leverage has been vast, while it has sharpened the æsthetic sense to some of its most delicate perceptions, and in some instances brought a new accession of intellectual power. The intuition which men trust in the dark, gradually leads the whole nature towards the light. Its dimness and its dumbness are exchanged for clearness and an intelligible voice; and while it thus grows luminous, it gains new power, and our confidence in its verdict strengthens. We have now stated what seems to us the general nature of the theistic intuition, and added one or two criteria by which all intuitions must be tested. It remains that we indicate more precisely the phases which it assumes; and the channels in which it works. Though ultimate and insusceptible of analysis, it has a triple character. It manifests itself in the consciousness which the human mind has of the Infinite (an intellectual phase); in its perception of the world-soul, which is Nature's 'open secret' revealed to the poet (an æsthetic phase); and in the act of worship, in which an object correlative to the worshipper is revealed in his very sense of dependence (a moral and religious phase).
