because in so doing I believe I have found a kind of key that opens
at the same time many mysteries in Roman history and in contemporary
life. The ancient writers and moralists wrote so much of Roman
corruption, because--nearer in this, as in so many other things, to
the vivid actuality--they understood that wars, revolutions, the great
spectacular events that are accomplished in sight of the world, do not
form all the life of peoples; that these occurrences, on the contrary,
are but the ultimate, exterior explanation, the external irradiation,
or the final explosion of an internal force that is acting constantly
in the family, in private habit, in the moral and intellectual
disposition of the individual. They understood that all the changes,
internal and external, in a nation, are bound together and in part
depend on one very common fact, which is everlasting and universal,
and which everybody may observe if he will but look about him--on the
increase of wants, the enlargement of ideas, the shifting of habits,
the advance of luxury, the increase of expense that is caused by every
generation.

Look around you to-day: in every family you may easily observe the
same phenomenon. A man has been born in a certain social condition and

luxuries increased. When a certain point was reached, he stopped. The
men are few who can indefinitely augment their particular wants, or
keep changing their habits throughout their lives, even after the
disappearance of vigour and virile elasticity. The increase of wants
and of luxury, the change of habits, continues, instead, in the new
