Habermas political philosophy is the political implementation of his practice philosophy,but not a independent system.He believes that subject emerges from the inter-subject communication; denies any “unanimous agreement” because it will be a hindrance of the openness of communication and the self-discipline of subject; the openness of the legislation is the thoroughfare between private and public self-discipline.The ideas on openness are affected by Hegel and Marx.
