There are unquestionably fundamental powers and laws in human nature which have their development in the course of history. There are certain primitive ideas, imbedded in the constitution of each individual mind, which are revealed in the universal consciousness of our race, under the conditions of experience--the exterior conditions of physical nature and human society. Such are the ideas of cause and substance; of unity and infinity, which govern all the processes of discursive thought, and lead us to the recognition of Being in se;--such the ideas of right, of duty, of accountability, and of retribution, which regulate all the conceptions we form of our relations to all other moral beings, and constitute morality;--such the ideas of order, of proportion, and of harmony, which preside in the realms of art, and constitute the beau-ideal of esthetics;--such the ideas of God, the soul, and immortality, which rule in the domains of religion, and determine man a religious being. These constitute the identity of human nature under all circumstances; these characterize humanity in all conditions.
