G.k. Chesterton said this quote

England and the English governing class never did call on this absurd deity of race until it seemed, for an instant, that they had no other god to call on… the truth of the whole matter is very simple. Nationality exists, and has nothing in the world to do with race. Nationality is a thing like a church or a secret society. It is the product of the human soul and will; it is a spiritual product. And there are men… who would think anything and do anything rather than admit anything could be a spiritual product.
