Abstract: The intellectuals, also known as the producers of views and values, are an important academic thesis. The criticism of “Person in Abstract” and the revelation of “Person in Reality” in German Ideology concern the ideology of intellectuals, and are of great significance to contemporary intellectuals. If starting from “Person in Abstract”, the intellectuals might lose their realistic concern, falling to “Intellectual in Abstract”, and be caught in personality illusions, thus seeking personality achievement and human liberation by moral preaching. In addition, intellectuals might stray into the wrong paths from pure speculation detached from reality to double arrogation of theory and reality. It will lead to identity loss, professional conceit and losing class consciousness caused by class origins with unclear labor divisions. Only from the perspective of “Person in Reality” to conduct self-recognition and research can the intellectuals in the new era achieve ideal personalities in practice, speculate and critique based on the reality, and pursue the truth without losing their class property, thus making a big difference in the new journey as well as realizing their own values.
