What are the sources of progressive development?

The sources of progressive development in many philosophical systems look different. For John Locke, this is a person with his aspirations to realize his ideals, and Hegel believed that in the process of development, human society cognizes itself and the world around it, merging with nature and the Absolute. An individual, pursuing his own goals, does not realize that he is pursuing the interests of others. For Marx, the driving force behind progress was the class struggle between the capitalists and the proletariat for the instruments of production. Gumilyov believed that the interaction of civilization with the environment is the path to progress and development.
