I reckon my fifth period to begin from the time when I had totally abandoned the claim of the Canon of Scripture, however curtailed, to be received as the object of faith, as free from error, or as something raised above moral criticism; and looked out for some deeper foundation for my creed than any sacred Letter. But an entirely new inquiry had begun to engage me at intervals, viz., the essential logic of these investigations. Ought we in any case to receive moral truth in obedience to an apparent miracle of sense?
