According to Nietzsche in On the Genealogy of Morals what is the value of morality?
Nietzsche in this text argues very strongly against any concept of morality, believing it to be untrue and deeply unhelpful to humanity as a whole. He argues very cogently that the beliefs a civilisation consider to be "moral" are actually based not in any sense of essential, unchanging "goodness," but actually are based on a sense of resentment and hatred of anything that emerged from a sense of inadequacy and expressed towards others that were stronger than man and more powerful. The only purpose of morality, therefore is to keep the human species back from achieving what it is capable of achieving and turning mankind's aggressive instincts against themselves as they try to live up to a moral code that they have convinced themselves is based in such untouchable ideas as belief in God or a higher order, whereas actually in fact they are only keeping themselves back from developing as they ought. Note what Nietzsche writes about morality and the danger that it represents to man in the following quote:
We can see nothing today that wants to grow greater, we suspect that things will continue to go down, down, to become thinner, more good-natured, more prudent, more comfortable, more mediocre, more indifferent, more Chinese, more Christian—there is no doubt that man is getting 'better' all the time.
The value of morality therefore only lies in the way that it deceives mankind to believe its creeds and to dedicate their lives to try and follow a moral code that is only created and definitely not a reflection of any divine truths. Nietzsche saw morality as a key enemy of mankind, something that held mankind's development up and represented a danger to man's progression.
