Opinions have changed with regard to the value of evidences in general, and the historic form of them in particular. When Boyle(650) at the end of the seventeenth century, and Bampton and Hulse in the latter half of the eighteenth, established their respective lectures, they looked forward to the probability of the occurrence of new forms of doubt, and to the importance of reasoning as the weapon for meeting them. In more recent times evidences have been undervalued, through the two opposite tendencies of the present age, the churchly and corporate tendency on the one hand, which rests on church authority, and the individualising tendency on the other, which rests on intuitive consciousness.(651) Evidences essentially belong to a theory, which places the test of truth objectively in a revealed book, and subjectively in the reason, as the organ for discovering morality and interpreting the book.(652) While evidences in general have been undervalued for these reasons, the historic branch of them has been regarded as obsolete, because having reference only to an age which doubts the documents and charges the authors with being deceivers or deceived, and unavailing, like an old fortification, against a new mode of assault. This latter statement is in substance correct. It lessens the value of this argument as a practical weapon against the doubts which now assail us, but does not detract from the literary value of the works in the special branch to which they apply. If the progress of knowledge be the exciting cause of free thought, a similar alteration in the evidences would be expected to occur from causes similar to those which produce an alteration in the attack, independently of the change which occurs from the necessity of adjusting the one to the other.
