Beyond Good and Evil is one of the most representative works of Friedrich Nietzsche (1844-1900). He considered it his most important and most comprehensive book. Here the poet-philosopher (as he was called by many) puts in check all Western philosophy practiced until his time.

The thinker who came to reinvent philosophy argued that philosophy should reflect deeply on the world around it and position itself, no matter what. In this work, whose theme is, above all, the cultural and spiritual precariousness of his time, Nietzsche affirms the need for men, in the eternal return of life and human history, to rise, accepting their own finitude, surpassing their own condition and living sovereignly in the joy and pain of the truth itself. Against the weak, the humble, the pitiful, he affirms the ideal of supermen, upon whom the future of humanity would depend.

Controversial and always provocative, Nietzsche develops the concepts of 'will to power' and 'lord morale'. The moral of the lord is the one to be followed and imposed, which shows what is good, true and beautiful, in contrast to the 'slave morality'. It is up to each human being to decide whether he is master or slave.
