The desire to achieve unity in various sections of human life, belief, and activity--and in humanity itself--is only a dream. The differences are there, and will, in some altered form, still be there even under the surface of any cheerful pseudo-Utopia of a unified world, or section of the world. There is no profit in denying them, only self-deception. The only real unity can come out of inner expansion, out of a great heart which excludes nothing and no one; but this will still not be uniformity.
