Felix Adler

We cannot adopt the way of living that was satisfactory a hundred years ago. The world in which we live has changed, and we must change with it. - Felix Adler

Ethical religion can be real only to those who are engaged in ceaseless efforts at moral improvement. By moving upward we acquire faith in an upward movement, without limit. - Felix Adler

The unique personality which is the real life in me, I can not gain unless I search for the real life, the spiritual quality, in others. I am myself spiritually dead unless I reach out to the fine quality dormant in others. For it is only with the god enthroned in the innermost shrine of the other, that the god hidden in me, will consent to appear.  - Felix Adler, "The Ethical Philosophy of Life"
