It is through man that Nothingness comes into the world. Freedom is the nature of man. This consciousness of freedom is disclosed in anxiety. There is thus an internal connection among nothingness, freedom and anxiety. These are inter related structural determinants of being of man.
Bad faith is a form of self-deception which in making use of freedom denies it.
Bad faith is again to lying, yet not identical with it. In lying one hides the truth from others. In bad faith one hides the truth from oneself. Bad faith does not come from outside. Consciousness affects itself with it.
