Even if the common ground of the Friendship is nothing more momentous than stamp-collecting, the circle rightly and inevitably ignores the views of the millions who think it a silly occupation and of the thousands who have merely dabbled in it. The founders of meteorology rightly and inevitably ignored the views of the millions who still attributed storms to witchcraft. There is no offence in this. As I know that I should be an Outsider to a circle of golfers, mathematicians, or motorists, so I claim the equal right of regarding them as Outsiders to mine. People who bore one another should meet seldom; people who interest one another, often.
