(Friedrich Nietzsche (1844-1900), German philosopher, classical scholar, critic of culture. Friedrich Nietzsche, Sämtliche Werke: Kritische Studienausgabe, vol. 5, p. 89, eds. Giorgio Colli and Mazzino Montinari, Berlin, de Gruyter (1980). Beyond Good and Evil, "Fourth Part: Maxims and Interludes," section 81 (1886).)
I don't see America as a mainland, but as a sea, a big ocean. Sometimes a storm arises, a formidable current develops, and it seems it will engulf everything. Wait a moment, another current will appear and bring the first one to naught.
(Jacques Maritain (1882-1973), French philosopher. Reflections on America, ch. 4 (1948).)
Who heeds the waste abyss of possibility? The ocean is everywhere the same, but it has no character until seen with the shore or the ship.
