From C.S. Lewis, FOUR LOVES:
It is therefore easy to see why Authority frowns on Friendship. Every real Friendship is a sort of secession, even a rebellion.
In each knot of Friends there is a sectional “public opinion” which fortifies its members against the public opinion of the community in general. Each therefore is a pocket of potential resistance. Men who have real Friends are less easy to manage or “get at”; harder for good Authorities to correct or for bad Authorities to corrupt. Hence if our masters, by force or by propaganda about “Togetherness” or by unobtrusively making privacy and unplanned leisure impossible, ever succeed in producing a world where all are Companions and none are Friends, they will have removed certain dangers, and will also have taken from us what is almost our strongest safeguard against complete servitude.
Down with democracy. Long live the Republic!
