Abstract: Marx, from the reality of people, from the historical production process, and from the criticism of capital, defines need as human "normal" survival and development, object-oriented practice need and the need of social relations, and the unification of value category, practice category and relation category. Heller considers Marx's need as the value category in her book The Theory of Need in Marx. The value judgments and value orientation are included in the content of need, the classification of need and the significance of need. Heller puts too much emphasis on value judgments and ignores social and historical analysis of capitalism, which plunges her into the utopia.
