He is known for the proposition of the Master/Slave morality. In discussing Slave morality, he is true. Ressentiment characterizes the average prole, the average citizen, simmering in rage, to be comforted by beer and television, sports and gossip and conflict with the family and neighbors.
But the Morality of the Master is hopelessly muddled. The Master and the Free Spirit are hopelessly muddled together.
The Master is the Slavemaster. His/her will to power is over something or someone. The will to power of the free spirit is within one’s self, over one’s self, not over external beings. External beings do not play into the will to power within the self. That is why Nietzsche offered the concept that God is Dead. Whether or not God is Dead, in fact, is immaterial to the Free Spirit. Other spirits may be greeted warmly, but with a sense of distance; they matter little in the matter of one’s self. Slave, God or Master – all of these are but the same.
The Slavemaster cannot exist as but a mirror of the Slave. They strive towards a different morality, copied from the Free Spirit. But the Will to Power is only the jealousy of the prole, satisfied; the ressentiment of not having a certain thing, satisfied. To go back to the slave is to measure one’s self in the mirror of the Slave.
Remember these two beings are as different as night and day.
