Abstract: From Hegel， Feuerbach to Marx， successive philosophical revolutions have led to the focus of disputes over the concept of reality. Hegel promoted reality as the content of philosophical research. Reality in Hegelian philosophy is something inevitable in the process of its development， and it is the objectified existence of spiritual entity. After Feuerbach's philosophical revolution of Hegel， the fundamental provisions of reality have changed from rationality to perceptuality， from the objective existence of absolute spirit to the existence of directness. In Marx's revolution of Feuerbach's philosophy， Hegelian philosophy and empiricism， reality has become the objectified existence of labor， and reality is historical. The process of philosophical revolution is also the history of the changes of the meaning of the concept of reality.
