Bad faith is commonly conceived as lying to oneself or self-deception. This folk definition is too simplistic as it undermines the rich ontological underpinnings of bad faith. While both simple self-deception and bad faith are opposed to the general phenomenon of lying (to others), for Sartre bad faith is also meant to explain both the working of consciousness and the ubiquity of pre-judicative nothingness. Together, consciousness and nothingness supply the special ontological foundation required for bad faith to operate. To enter (...) into bad faith is to escape from the anguish of the experience of insubstantiality and freedom into deterministic attitudes about the self, such as the deceiver/deceived bipolarity of Freudian psychoanalysis. Sartre rejects the thesis that there can be hidden motivations in consciousness by arguing for the reflexivity and the translucency of consciousness. Further, he would take the ubiquity of nothingness to explain the wide prevalence of bad faith as a state-of-being in the world. Bad faith cannot be equated with simple cases of self-deception as bad faith is sustained by a unique mix of ontological postulates. Sartre argues for this point cogently through his examples of bad faith in Being and Nothingness. In these examples, Sartre shows that sincerity, the purported anti-thesis of self-deception, causes one to fall even deeper into bad faith. (shrink)
