Facticity is both a limitation and a condition of freedom. It is a limitation in that a large part of one’s facticity consists of things one couldn’t have chosen (birthplace, etc.), but a condition in the sense that one’s values most likely depend on it. However, even though one’s facticity is “set in stone” (as being past, for instance), it cannot determine a person: The value ascribed to one’s facticity is still ascribed to it freely by that person. As an example, consider two men, one of whom has no memory of his past and the other remembers everything. They have both committed many crimes, but the first man, knowing nothing about this, leads a rather normal life while the second man, feeling trapped by his own past, continues a life of crime, blaming his own past for “trapping” him in this life. There is nothing essential about his committing crimes, but he ascribes this meaning to his past.
However, to disregard one’s facticity when, in the continual process of self-making, one projects oneself into the future, would be to put oneself in denial of oneself, and would thus be inauthentic. In other words, the origin of one’s projection must still be one’s facticity, though in the mode of not being it (essentially). Another aspect of facticity is that it entails angst, both in the sense that freedom “produces” angst when limited by facticity, and in the sense that the lack of the possibility of having facticity to “step in” for one to take responsibility for something one has done also produces angst.
What is not implied in this account of existential freedom, however, is that one’s values are immutable; a consideration of one’s values may cause one to reconsider and change them. A consequence of this fact is that one is responsible for not only one’s actions, but also the values one holds. This entails that a reference to common values doesn’t excuse the individual’s actions. Even though these are the values of the society of which the individual is part, they are also their own in the sense that they could choose them to be different at any time. Thus, the focus on freedom in existentialism is related to the limits of the responsibility one bears as a result of one’s freedom: the relationship between freedom and responsibility is one of interdependency, and a clarification of freedom also clarifies that for which one is responsible.
