Who do we mean when we talk about a person? Alexander the Great or Newton, Russian or French, peasant or craftsman, man or woman, adult or child? We can say that a person is all the people who once lived and now live. But often people kill other people, i.e. denied them the right to be human. One person may treat another or others as inferior beings, considering them cogs for the implementation of their plans, cannon fodder for waging wars. Yes, and in many people the animal nature sometimes breaks through, such merciless anger and hatred that it is difficult to call them people. Often the very conditions of existence force a person to suppress human qualities in himself, to hide them, to constantly change his nature. Each of the people can call himself a man, but this is not recognized by everyone. Yes, he himself does not recognize the same person in everyone. Not always, therefore, this name is true. Man is a creature that does not always correspond to his concept.
