For a philosopher, art is a creative way of knowing the world, in the process of which artistic images are created. In aesthetics, it is a form of human activity that satisfies the artistic needs of people. For an art historian, this is the artistic culture of society as a whole and its individual types. In social science, art is a part of the spiritual sphere of social life, which reproduces reality through creativity. Having added and mixed all these definitions, we will derive a universal formula that gives a peculiar answer to the question of what art is. Art is different types of human cultural activity aimed at understanding the world with the help of artistic images, reproducing reality through creativity and satisfying the aesthetic needs of people.
