Victor Hugo, Les Miserables

Matter is, the moment is, interest is, the belly is; but the belly must not be the only wisdom. The momentary life has its rights, we admit, but the permanent life has its also. Alas! to have risen does not prevent falling. We see this in history oftener than we would wish. A nation is illustrious; it tastes the ideal; then it bites the filth, and finds it good; and if we ask why it abandons Socrates for Falstaff, it answers: "Because I love statesmen."
