The main problem of the article is the question, if human death is necessary. There are three types of necessity of death: logical necessity, metaphysical necessity and biological necessity. The subject of the article is logical necessity of death. According to the author human death is not necessary, because the sentence “All humans are mortal” is not necessary truth. We can imagine people who will never die, so we cannot say, that mortality is the necessary feature of human beings. Strictly speaking, neither mortality, nor immortality constitute the essence of the human nature.
