Sorry friedrich, i don't agree. There are legitimate concepts of good bad and evil. Sure some of these may be based off other values, but the total idea of 'good' or 'bad' based of a mixture of those other values.

"that which has proved itself useful is good" - see i don't agree with that. There are many things that would be useful. Slavery would be extremely useful. Cheap labor = cheaper products and less civil (for lack of a better word) drama. Yea that would be more useful.

Another problem i have: I have never heard the rich call themselves or be called the "truthfull". I don't know any wealthy people who consider themselves more truthful than others, i know plenty who know they are liars.

I feel like i'm watching a televangilist or a stuck up forbes reporter or a political figure who speaks like they know the people and the peoples thoughts/needs, but they really don't.

in short: Nietzsche, i'm not in agreement sir.
