"Altruism is an instinct we've inherited from the small society where we knew for whom we work, whom we serve. When you pass from this, as I like to call it, 'concrete society', where we are guided by what we see, to the abstract society which far transcends our range of vision, it becomes necessary that we are guided not by the knowledge of the effect of what we do, but by some abstract symbols. Now, the only symbol which tells us where we can make the best contribution is profit. And in fact by pursuing profit, we are as altruistic as we can possibly be, because we extend our concern to people who are beyond our range of personal conception. This is a condition which makes it possible to produce what I call an extended order, an order which is not determined by our aim, by our knowing what are the most urgent needs, but by an impersonal mechanism which by a system of communication puts a label on certain things which is fully impersonal."
