The Spciety which I have the privilege of addressing, has been organized with the above for its motto. Some of my hearers have entirely abandoned the tenets of the positive religions; others continue to hold them true, but, are discouraged by the lack of spiritual force, the prominence given to mere externals, the barren formalism in the churches and synagogues. We agree in believing that theology is flourishing at the expense of religion. It seems to us that differences in creed are constantly increasing, and will continue to multiply with the growth and differentiation of the human intellect. We perceive that every attempt to settle problems of faith has thus far signally failed, nor can we hope for better results in the future. Certainty even with regard to the essential dogmas appears to us impossible. We do not therefore deny dogma, but prefer to remit it to the sphere of individual conviction with which public associations should have no concern. Far from believing that the doctrines of religion as commonly taught are essential to the well being of society, we apprehend that the disputes concerning the "author of the law" have diverted the attention of men from the law itself, and that the so-called duties toward God too often interfere with the proper performance of our duties toward one another. It were better to insist less upon a right belief, and more upou right action. In order to find a common basis whereon good men, whether believers or unbelievers can unite, we look to the moral law itself, whose certainty rests in the universal experience of civilized Humanity. We shall hold questions of faith in abeyance, shall endeavor to stimulate the conscience and to this end shall seek to awaken an interest in the grave social problems of our day, which need nothing so much as a vigorous exertion of our moral energies, in order to arrive at a peaceable solution. To broaden and deepen the ethical sentiment in ourselves, and to hold up to the sad realities of the times, the mirror of the ideal life, is the object with which we set out. We do not therefore delude ourselves with the hope that the ideal will ever be fully realized, but are convinced that in aspiring to noble ends the soul will take on something of the grandeur of what it truly admires. Starting with the assumption that the doctrines of religion are incapable of proof, it behooves us to show in one or more instances the fallacy of the arguments upon which they are commonly founded, and we shall begin with the doctrine of IMMORTALITY.
