In the earliest age of the church, previous to the establishment of Christianity as the state religion, we observe the unaided appeal to argument, and especially the abundant use made of the internal evidence, or philosophical argument concerning the excellence of Christianity, as a means for arresting attention, preparatory to the presentation of the external and historic proof.(1029) In the long interval of the middle ages, the church was able to supplement or supersede argument by force; yet it must be admitted that the political and intellectual condition of the European mind was then, to a large extent, such as to receive benefit from the imposition of an external rule of religious authority and doctrine, in the same manner that individuals, when in a state of childhood, need a rule, not a principle; a law, not a reason.(1030) This method however was unsuited when the mind of Europe awoke, and when free thought could no longer be suppressed by force. The history of evidences since the spread of modern unbelief exhibits not only the return to the ancient Christian weapon of argument instead of force; but not unfrequently to the ancient mode of presenting the philosophical proof prior to the historical. An attempt of this kind was intermingled with the English school of evidences of the last century; and the argument of analogy used by Butler, if viewed as constructive, and not refutative, may be considered to have for its object to prepare the mind for accepting revealed religion, by first showing the probability of it on the ground of its similarity to nature. (48) And in the German movement, where the doubt thrown by criticism over the historical evidences even still more compelled the resort to the philosophical argument on the part of those who strove to defend the faith, we have seen various attempts to reconstruct Christianity from the philosophical side.(1031) Both methods, the philosophical and the historical, have had their place; but their use has varied with the wants of the age. In proportion as the pressure of doubt left less opportunity for the constraining force of the latter, the persuasiveness of the _à priori_ moral argument has been used. The history of the means which have been successful in removing doubts lends little support to the opinion which would save the faith by the sacrifice of the reason, or would imperil the truth of religion by throwing discredit on the immutability of moral distinctions, perceived by the conscience which Providence has placed in the human mind; to which the great writers on evidence have been wont to make their appeal; and which they have justly perceived must lie at the basis of the evidences themselves. “If the light that is in thee be darkness, how great is that darkness!”
