Concupiscence

Concupiscence
is the spontaneous movement of our
sensual appetite
toward what we imagine as pleasant
and away from what we imagine as
painful.

Concupiscence of the eyes
is an unreasonable desire
to see, hear, and know
what is harmful to our virtue,
inconsistent with our state
in life,
or detrimental to
our higher duties.

An example
would be the desire
to accumulate material possessions
irrespective of the means employed,
satisfy our ambitions,
or nurture our pride.
