There are many forms of dehumanization, and one of them, the most crucial, perhaps one that is systematic in disregard of differences, to the extent that such a failure - in the micro sense - takes the individual away from their ability to co-exist and, consequently, away from the possibility of learning, personal growth and development; in the macro sense, leads society to xenophobisms, exaggerated nationalism, genocidisms, biocidisms, apartheids, socio-economic exclusion and unilateral and unorthodox ways of seeing the world, culminating in wars, armed conflicts, hatred and radical political positions.However, one cannot and should not lose hope, although for many it, the search for respect for differences, sounds just as another great utopia. That is, you must still believe that man can become qualitatively. It is necessary to believe, as Nietzsche would tell us that "man can and must be overcome."Like all works on human development by the author produced, this also brings an afterthought, a second unit as a complementary theme, about the possibilities of change, humanization and development of being. We hope that this work, as well as many others, can be useful to the formation of a more just and democratic society in that it is able to contribute to the formation of a less alienated generation and uncompromised with the social, economic and humanitarian.
