(c). Argument from fact: instances of old men in
public and in private life who till death were
actively at work 23-26

B. Rebuttal of the second charge, that old age weakens the physical powers.

(a). Old age does not desire nor require the strength
of youth, because it may exert influence
through other means. Instances cited to show
this 27-32

(b). Temperate habits will retain a good measure
of strength till old age (33, 34); many instances
of weakness in old age may be attributed to
ill-health, which is common to all periods of
life (35); proper care will greatly retard decay 33-38

C. Refutation of the third charge, that old age takes away the capacity for
enjoyment

(a). The pleasures in which youth finds its keenest
enjoyment are in themselves bad, and old age
is beneficent in freeing from their allurements 39-44

(b). Old age has pleasures far more refined and satisfying
than those of sense 45-64
Such as, those of conversation and literature
(45-50); especially those of agriculture (51-61);
