Lying to Yourself

We discussed in class that Sartre believed in us having Bad Faith or the act of us "fleeing from our freedom". We also stated that amongst this idea was the concept of lying to yourself. We went back and forth how if lying to ourselves was actually in fact to deceive as when lying to others, or if we typically know the truth the entire time. Well we came to the agreement that we can't deceive ourselves since we already know the truth, but I take it as we try to "lie to ourselves" in order to comfort ourselves or as Sartre puts it flee from our freedom. In existentialism in Sartre's point of view when we decide to make a choice you negate or decline to make any other choice you could possibly make. When taking this into consideration with the idea of lying to yourself  it coincides with my belief with only try to comfort ourselves. We flee from the freedom of failing or rejection or whatever we don't agree with and negate to believe we succeeded in whatever we may do. This concept of lying to ourselves is in part due to we can't accept our facticity in the state of  "being-in-itself". The facticity of a being-in-itself is basically what is given to us so the way we are perceived by others. This perception can even cause us to be the judgmental of  ourselves and harder on ourselves to not face the criticisms of others. We try to flee from the freedom of being concerned with what others think of us, but that idea of trying to not be concerned with what they think is an action based on what others think. When we attempt to lie to comfort ourselves we must think does the statements of others truly define us as a person? Do the facticity of being-in-itself truly identify you? The answer would be no, but that would be a lie yourself because in the world we live in we are always defined by something that wasn't given to us.
