A famous student of history has bequeathed to us a definition of nationality which is worth attention: I refer to Ernest Renan, of whom George Meredith once said to me, while the great French critic was still living, that there was more in his head than in any other head in Europe. Renan tells us that "Man is enslaved neither by his race, nor by his language, nor by his religion, nor by the course of rivers, nor by the direction of mountain ranges. A great aggregation of men, sane of mind and warm of heart, creates a moral consciousness which is called a nation."
