One of my exponents favorite in areas of a job social rather philosophic is the philosopher Friedrich Nietzsche, was born on October 15, 1844, in Röcken bei Lützen, Germany. In his brilliant but relatively brief career, he published numerous major works of philosophy,  In the last decade of his life he suffered from insanity; he died on August 25, 1900. I chose it because its approach is very revolutionary, in many areas as politicians, social, religious, etc. And for this last was considered the antichrist, accusing of a false morality collective generating behaviour and social prejudice suppress our instinct animal, so, why the animal instinct it is important according to him, because considers that the conduct social and naturalized arise from social processes that suppress our soul, what it is supposed which is the only thing we belongs to us as individuals, enabling justified in branches philosophical and social that we as people we must strip us of morality and hold on to our own ethics. And achieve define the good or evil from ourseleves.
