“The [sun and moon] provide us with different-appearing worlds, which in turn form our two different minds; the one that reasons and the one that dreams.”

“There's so many different worlds, so many different suns. And we have just one world, but we live in different ones.”

“215. As in the stellar firmament there are sometimes two suns which determine the path of one planet, and in certain cases suns of different colours shine around a single planet, now with red light, now with green, and then simultaneously illumine and flood it with motley colours: so we modern men, owing to the complicated mechanism of our "firmament," are determined by DIFFERENT moralities; our actions shine alternately in different colours, and are seldom unequivocal—and there are often cases, also, in which our actions are MOTLEY-COLOURED.”

“God has given us many faiths but only one world in which to co-exist. May your work help all of us to cherish our commonalities and feel enlarged by our differences.”

“In that little party there was not one who would desert another; yet we were of different countries, different colours, different races, different religions--and one of us was of a different world.”

“The real world has its limits; the imaginary world is infinite. Unable to enlarge the one, let us restrict the other, for it is from the difference between the two alone that are born all the pains which make us truly unhappy.”
