This is a citation from the Existentialists-most particularly Jean-Paul Sartre.As you know,I think we need to learn from everyone and every situation.Muslims, particularly, need to reflect on this phenomenon as it is endemic in our community.It does have a parallel concept in Islam-nifaq(hypocrisy) but that concept has a more specific meaning around those who don’t really believe in the religion.The concept of”bad faith” has a more general application and can apply to believing Muslims and Christians as well.Thus it has a more general applicability.See if you can spot it in or around you.This is a very important matter for Muslims who are more susceptible to social and family pressure than most and often use the terms of the religion -‘adab’, ‘bir walideyn’,avoiding ‘ghiba’ etc. to prevent themselves from being authentic.Think about it.
Bad faith (French: mauvaise foi) is a philosophical concept utilized by existentialist philosophers Simone de Beauvoir and Jean-Paul Sartre to describe the phenomenon in which human beings, under pressure from social forces, adopt false values and disown their innate freedom, hence acting inauthentically.[1] It is closely related to the concepts of self-deception and ressentiment.
