Quotes from the same author

The right for the right's sake is the motto which everyone should take for his own life. With that as a standard of value we can descend into our hearts, appraise ourselves, and determine in how far we already are moral beings, in how far not yet.
 Felix Adler
In order to join vigorously in the moral work of the world I must believe that somehow the best I can accomplish will endure, will leave its trace on things, will aid the final consummation.
 Felix Adler

 Felix Adler
I believe in the supreme excellence of righteousness; I believe that the law of righteousness will triumph in the universe over all evil; I believe that in the attempt to fulfil the law of righteousness, however imperfect it must remain, are to be found the inspiration, the consolation, and the sanctification of human existence. We live in order to finish an, as yet, unfinished universe, unfinished so far as the human, that is, the highest part of it, is concerned. We live in order to develop the superior qualities of man which are, as yet, for the most part latent.
 Felix Adler
There is a universal element in man which he can assert by so acting as if the purpose of the Universe were also his purpose. It is the function of the supreme ordeals of life to develop in men this power, to give to their life this distinction, this height of dignity, these vast horizons.
