马克思主义是关于人的发展、人的自由与解放的学说。唯物史观的创立使人性理论成为科学。人性复归是人对自己人性的把握和占有,是人类解放与自由的一个重要环节。社会关系是制约人性复归的客观现实环境,劳动异化的消除是人性复归的必要条件,利益对抗的消失是人性复归的根本前提,生产力的高度发达是人性复归的根本物质力量。 Marxism is a doctrine of human development, human freedom and liberation. The creation of historical materialism made humanity theory a science. The return of human nature is the grasping and possession of human nature by human beings and is an important link of human liberation and freedom. Social relationship is an objective reality that restricts the return of human nature. The elimination of labor alienation is a necessary condition for the return of human nature. The disappearance of antagonism of interest is the fundamental premise of the return of human nature. The highly developed productive forces are the fundamental material forces for the return of human nature.
