Ethics

1. Does "ethics" in the text below mean "logic, reasoning, and argument"?

2. Does "the excess of destructiveness" mean "the enormous destructiveness"?

3. Does "in the exercise of ‘mastery or the will to power’" mean "in the form of domination and power seeking"?

However, the gist of my argument will be that the artist, rather than taking him- or herself as an object to be destroyed, finds a surrogate ‘object’ to channel the potentially dangerous defusion of the instincts involved in primary masochism so that the fragmentation they incur is experienced at a distance, although, paradoxically, an
extremely intimate one. The ethics involved here is that the excess of destructiveness that seems to be inherent in human sexuality is dissipated via an internal relation to a surrogate self rather than projected outwards and inflicted on an external object in the exercise of ‘mastery or the will to power’ (Art and Psychoanalysis by Maria Walsh).
