Transcendentalism was, in fact, a reaction against the moral and political skepticism which resulted directly from the prevailing philosophy of sensation. Since Bacon's day, religious beliefs had been taking hold on the enlightened mind of England and Europe. The drift of speculation was strongly against, not the Christian system alone, but natural religion, and the ideal foundation of morality. The writings of Collins, Dodwell, Mandeville, expressed more skepticism than they created, and betrayed a deeply-seated and widely-spread misgiving in regard to the fundamental truths of theology. Hume's argument against the credibility of miracles was never answered, and the anxiety to answer it was a confession of alarm from the heart of the church. The famous XVIth chapter of Gibbon's "Decline and Fall of the Roman Empire" was assailed furiously, but in vain, each assault exposing the weakness of the assailants; and it was only by adopting his history, and editing it with judicious notes, that the church silenced the enemy it could not crush. The deists of the seventeenth century in no wise balanced their denials by their affirmations, but left Christianity fearfully shattered by their blows. The champions of the church fought skepticism with skepticism, conceding in substance the points they superficially attacked. Towards the close of the seventeenth century Cudworth confronted atheism with idealism, retreating upon Plato when the foe had carried the other works; early in the century following, Butler, in the celebrated "Analogy," fought infidelity with weapons that infidelity might have turned, and since has turned with deadly effect, against himself. The ablest representative of Unitarianism was Joseph Priestley, a materialist of the school of Hartley. The cardinal beliefs of religion were debated in a way that was quite unsatisfactory in the light of reason, showing the extent to which faith had been undermined. Indeed, had it not been for the power of institutions, customs, respectability, and tradition, the popular beliefs would have all but disappeared, so deep into the heart of the people unbelief had penetrated. The church stood fast, because it was allied with power and fashion, not because it was supported by reason or faith. The whole tone of feeling on sacred and ethical topics was low; divine ideas were defended by considerations of expediency; God was a probability; the immortality of the soul a possibility, a supplement to skepticism, an appendix to a philosophy which, finding no God here, presumed there must be one hereafter. There is no more soulless reading than the works of the Christian apologists of the seventeenth century. The infidels had more ideas, and apparently more sincerity, but in neither was there any spiritual impulse or fervor.
