It is impossible to feel equal respect for things that are in fact unequal unless the respect is given to something that is identical in all of them. Men are unequal in all their relations with the things of this world, without exception. The only thing that is identical in all men is the presence of a link with the reality outside the world.
All human beings are absolutely identical in so far as they can be thought of as consisting of a centre, which is an unquenchable desire for good, surrounded by an accretion of psychical and bodily matter.
