So you desire the happiness of others, perhaps that of your own child…

What are you going to do?

We should not
give the individual,
in so far as he desires his own happiness,
any precepts
or recommendations
as to the road leading to happiness;

for individual happiness
arises from particular laws
that are unknown
to anybody,

and such a man/woman
will only be hindered or obstructed
by recommendations
which come to him from outside sources.

Those precepts
which are called moral
are in reality directed against individuals,
and do not by any means make for the happiness of such individuals.

a. It is a prejudice to think that morality is more favorable to the
development of the reason than immorality.

b. Evolution does not make happiness its
goal; it aims merely at evolution, and nothing else.
