Etween the present volume and my work published i many years ago, and entitled Outlines of Moral Philosophy, there exists connection, in so far as that production of my youth, in which everything was only brie?y and generally sketched, finds here more c0pious expression; but besides this there is alteration, as the necessary consequence of a more profound research into the first principles and the religious postulates on which the science of Ethics is founded. Readers of my Christian Dogmatics will find here the same fundamental conceptions which formed the basis of that work, but treated from another point of view relatively independent of doctrines of belief.
