Karl Marx, one of the most influential thinkers in history, was profoundly shaped by the ideas of Georg Wilhelm Friedrich Hegel. Although Marx diverged from Hegel in significant ways, particularly by grounding his philosophy in materialism rather than idealism, he incorporated several key elements of Hegelian thought into his own theories. This essay explores five major Hegelian concepts that Marx adopted: the historical nature of thought and humanity, the process of self-transformation and self-actualization, the development of history through conflict and contradiction, the overcoming of alienation, and the dialectical method as a critical approach to understanding the world.
