Ludwig Feuerbach is a great and controversial German philosopher of the 19th century. His concept, according to which Christianity is not a religion, but a form of consciousness of man and humanity as a whole, amazed his contemporaries. Feuerbach called for giving up illusions, but not falling into pessimism, but, on the contrary, understanding that nature itself is designed to give each of us happiness. The scientist’s entire system is built on the concept of “consciousness”: a truly conscious individual does not need religion , not in an outdated tradition, but creates happiness for himself and others. Although Feuerbach spoke about personal happiness, he created a unique teaching about society as a union of different people who are ready to protect not only the common property, but also each other’s feelings. The influence of Feuerbach was experienced by a variety of thinkers: from Karl Marx, who saw in him the main link between the idealistic Hegel and historical materialism, to religious thinkers who noticed reflections of the new theology in his atheism. Feuerbach's thoughts sound unexpectedly relevant - but the search for oneself, the meaning of life, and everything lofty that exists in our world is always relevant.
