An overman as described by Zarathustra, the main character in Thus Spoke Zarathustra, is the one who is willing to risk all for the sake of enhancement of humanity. In contrary to the last man whose sole desire is his own comfort and is incapable of creating anything beyond oneself in any form. This should suggest that an overman is someone who can establish his own values as the world in which others live their lives, often unaware that they are not pregiven. This means an overman can affect and influence the lives of others. In other words, an overman has his own values, independent of others, which affects and dominates others lives that may not have predetermined values but only herd instinct. An overman is then someone who has a life which is not merely to live each day with no meanings when nothing in the past and future is more important than the present, or more precisely, the pleasure and happiness in the present, but with the purpose for humanity.
