By what sort of experience are we led to the conviction that spirit exists? On the whole, by searching, painful experience. The rose Religion grows on a thorn-bush, and we must not be afraid to have our fingers lacerated by the thorns if we would pluck the rose.
Felix AdlerReligion is a wizard, a sibyl . . . She faces the wreck of worlds, and prophesies restoration. She faces a sky blood-red with sunset colours that deepen into darkness, and prophesies dawn. She faces death, and prophesies life.
Felix AdlerLove is the expansion of two natures in such fashion that each include the other, each is enriched by the other. Love is an echo in the feelings of a unity subsisting between two persons which is founded both on likeness and on complementary differences. Without the likeness there would be no attraction; without the challenge of the complementary differences there could not be the closer interweaving and the inextinguishable mutual interest which is the characteristic of all deeper relationships.
Felix AdlerWe should seek to free the moral life from the embarrassments and entanglements in which it has been involved by the quibbles of the schools and the mutual antagonisms of the sects; to introduce into it an element of downrightness and practical earnestness; above all, to secure to the modern world, in its struggle with manifold evil, the boon of moral unity, despite intellectual diversity.
