Every man is recommended by nature to his own care, being fitter to

take care of himself than of another person
Every man is recommended by nature to his own care, being fitter to
take care of himself than of another person. We approve, therefore, of
each one seeking their own good; but then it must not be to the hurt of
any other being. The primary feeling of self-preservation would not of
itself, however, be shocked at causing injury to our fellows. It is
when we pass out of this point of view, and enter into the mental state
of the spectator of our actions, that we feel the sense of injustice
and the sting of Remorse. Though it may be true that every individual
in his own breast prefers himself to mankind, yet he dares not look
mankind in the face, and avow that he acts on this principle. A man is
approved when he outstrips his fellows in a fair race; he is condemned
when he jostles or trips up a competitor unfairly. The actor takes home
to himself this feeling; a feeling known as Shame, Dread of Punishment,
and Remorse.
