If it be true that general development in morality proceeds in spite of the original predominance of evil in the world, through the self-destructive nature of the latter, it is only necessary to examine the reasons why the excellence of the good may have been subject also to progress, and how the remainder of the race may have been influenced thereby. The development of morality is then probably to be understood in the following sense: Since the Divine Spirit, as the prime force in moral progress, cannot in itself be supposed to have been in any way under the influence of natural laws, its capacities were no doubt as eternal and unerring in the first man as in the last. But the facts and probabilities discussed above point to development of _religious sensibility_, or capacity to appreciate moral good, or to receive impressions from the source of good. The evidence of this is supposed to be seen in—_First_, improvement in man’s views of his duty to his neighbor; and _Second_, the substitution of spiritual for symbolic religions: in other words, improvement in the capacity for receiving spiritual impressions. What the primary cause of this supposed development of religious sensibility may have been, is a question we reverently leave untouched. That it is intimately connected in some way with, and in part dependent on, the evolution of the intelligence, appears very probable: for this evolution is seen—_First_, in a better understanding of the consequences of action, and of good and of evil in many things; and _Second_, in the production of means for the spread of the special instrumentalities of good. The following may be enumerated as such instrumentalities: 1. Furnishing literary means of record and distribution of the truths of religion, morality and science. 2. Creating and increasing modes of transportation of teachers and literary means of disseminating truth. 3. Facilitating the migration and the spread of nations holding the highest position in the scale of morality. 4. The increase of wealth, which multiplies the extent of the preceding means. And now, let no man attempt to set bounds to this development. Let no man say even that morality accomplished is all that is required of mankind, since that is not necessarily the evidence of a spiritual development. If a man possess the capacity for progress beyond the condition in which he finds himself, in refusing to enter upon it he declines to conform to the Divine law. And “from those to whom little is given, little is required, but from those to whom much is given, much shall be required.” ------------------------------------------------------------------------ _SCIENTIFIC ADDRESSES._ ------------------------------------------------------------------------
