Hope philosophy is also called "utopian philosophy". A philosophical thought put forward by e Bloch in Germany. It is generally considered to belong to western Marxism. It is believed that man and the world are open, the unfinished progress is in a state of "not yet", and the future is open to man, with infinite possibilities, from which man has all kinds of "hopes" for the future (the future of the world and his own future). Hope is the most human passion among all kinds of human passions. Because people in reality are always one-sided and incomplete. Full of humanity, real humanity is still ahead, and people should keep moving forward. For people, hope is not a dispensable thing, it is an inherent human need rooted in human nature and an indispensable ontological phenomenon. People live in hope, but they don't consciously realize its existence. They often exaggerate the power of the external objective world and ignore the inherent hope and creative power of human nature. The real mission of philosophy is to awaken people's utopian ability of hope and emotion. Human nature is full of hope and longing for the future. The history of human civilization is composed of countless utopias, including utopias aimed at redesigning the whole society and various local utopias, such as religious utopias, entertainment utopias, drama utopias and so on. Utopia can be divided into two categories: abstract Utopia and concrete Utopia. Marxism is a concrete utopia.
