The primary _officium_ (in a larger sense than our word Duty) of man is
(they said) to keep himself in the state of nature; the second or
derivative _officium_ is to keep to such things as are _according to
nature_, and to avert those that are _contrary to nature_; our
gradually increasing experience enabled us to discriminate the two. The
youth learns, as he grows up, to value bodily accomplishments, mental
cognitions and judgments, good conduct towards those around him,--as
powerful aids towards keeping up the state of nature. When his
experience is so far enlarged as to make him aware of the order and
harmony of nature and human society, and to impress upon him the
comprehension of this great _ideal_, his emotions as well as his reason
become absorbed by it. He recognizes this as the only true Bonum or
Honestum, to which all other desirable things are referable,--as the
only thing desirable for itself and in its own nature. He drops or
dismisses all those _prima naturae_ that he had begun by desiring. He
no longer considers any of them as worthy of being desired in itself,
or for its own sake.
