"We make our friends; we make our enemies; but God makes our next-door neighbour."

We make our friends; we make our enemies; but God makes our next-door neighbour. Hence he comes to us clad in all the careless terrors of nature; he is as strange as the stars, as reckless and indifferent as the rain. He is Man, the most terrible of the beasts. That is why the old religions and the old scriptural language showed so sharp a wisdom when they spoke, not of one's duty towards humanity, but one's duty towards one's neighbour. The duty towards humanity may often take the form of some choice which is personal or even pleasurable. That duty may be a hobby; it may even be a dissipation. We may work in the East End because we are peculiarly fitted to work in the East End, or because we think we are; we may fight for the cause of international peace because we are very fond of fighting. The most monstrous martyrdom, the most repulsive experience, may be the result of choice or a kind of taste....But we have to love our neighbour because he is there-- a much more alarming reason for a much more serious operation. He is the sample of humanity which is actually given us. Precisely because he may be anybody he is everybody. He is a symbol because he is an accident.

-Heretics (1905)
