It is probably true to say it is not ‘common sense which is the commonest thing in the world’, but common kindness. In the remotest regions, one can be amazed by seeing it suddenly and unexpectedly flower, as one can come upon a single poppy standing all by itself in a lonely valley, identical with every other poppy in the world, though it has never seen any of them, and has never known anything other the wind which from time to time ruffles the silk of its lonely scarlet standard.
