text: describe utilitarianism as an ethical system which is good and powerful? also give critizisms for which utilitarianism is weak and bad. it depends on which definition you employ: 1. worth or value is determined solely by utility; or, 2. that action is best which brings the greatest happiness to the greatest number.  #2 on the surface appears to be more humane than #1 although both are accepted definitions. look beyond the surface and you have to question the value of happiness and utility.  people would be happier if gas prices were low, but the planet would suffer making the happiness of future generations more elusive.
