To close our lecture with the only consoling view which the subject affords:—It is a happiness that even the most inveterate champions of this manner of thinking are always, against their own thought and will, something better than their speech proclaims them; and that the spark of a higher life in Man, however it may be concealed, is yet never extinguished, but gleams on with silent and secret power until material is presented to it at which it may kindle and burst forth into bright and steady flame. To fan this spark of a higher life, and as far as possible to furnish it with materials for its activity, is also one of the objects of these lectures.
