You think that a wall as solid as the earth separates civilization from barbarism. I tell you the division is a thread, a sheet of glass. A touch here, a push there, and you bring back the reign of Saturn.
John Buchan (1875-1940) Scottish novelist, poet, and politician; Governor-General of Canada (1935 -1940)
The Power-House, ch. 3 (1916)
