Sartre, Being-for-Others, & the Invisible Guest Theory
Every now and then, interesting conversations arise on social media, allowing for philosophical perspectives to interject and offer insight into the topic. I came across just such a conversation this past week when I saw people discussing the “Invisible Guest Theory.” As I tend to do, I immediately thought about how existential philosophy applies to this theory.
The Invisible Guest Theory suggests that people in social situations, such as a party, are too preoccupied with themselves and their own insecurities to pay any attention to anyone else; in effect, they are thinking entirely of themselves and have no time or attention to focus on or judge you.
This makes you an “invisible guest”––others are so consumed with themselves they don’t even notice you.
For example, you spend all night picking out your outfit for a party. You pick an outfit that you think will blow everyone else’s out of the water. Then you go, and you receive maybe one remark. After that party, a small percentage of people might remember even one article of clothing you had on.
You were an invisible guest. But how many others’ outfits did you commit to memory and would be able to recite afterward, either?
It makes sense that many of us experience what we’ve come to call “social anxiety” when going out and about in the world: we are living our lives and experiencing everything we do and perceive vividly. However, other people don’t experience us the same way.
In fact, this goes further than simply wondering how we are perceived in a large gathering of people. Something that was an important memory for us––be it good, bad, thrilling, embarrassing––is not necessarily so for somebody else, because they are not you. They are themselves, and the experience was perceived through their own consciousness.
Enter Jean-Paul Sartre into the Invisible Guest Theory.
This theory could well have come from Sartre’s Being and Nothingness. It is almost a perfect analogy for such concepts of his as Being-for-itself, Being-for-others, and The Look.
For Jean-Paul Sartre, the Self––that is, your being that you experience through your consciousness––is Being-for-itself. It is a free and conscious entity that defines its existence through choices that exercise its freedom in the world (i.e., every human being).
For every Being-for-itself (for every human being) there is a threat that presents itself to our freedom, as a threat to our Self: the Other.
The presence of the Other (another person) threatens our Self, because it upsets our sense of being in the center of the world. This is because, try as we might, we can all only experience the world as one Self––as our Self––and not through the consciousness of the Other.
Part of this entails understanding that to the Other, we cease to be the subject of our existence, but become an object of someone else’s. In a way, Sartre writes, we lose our subjective freedom. The Other will never understand the full subjectivity of our Self, because they do not have access to our consciousness, just as we do not have access to theirs.
This is a phenomenological concept Sartre coined as “The Look.” The Look describes how being observed by the Other turns us into a fixed object, triggering anxiety, self-awareness and self-consciousness, shame, and even loss of one’s identity.
Sartre writes that the Look turns us into Beings-for-others, beings whose only experience is being viewed and objectified by others, living only through the gaze of the Other and losing our sense of Self.
You might be wondering what all of this has to do with the Invisible Guest Theory I started this newsletter off with. Here’s how it connects.
Ultimately, you are never just a Being-for-itself or just a Being-for-others. You are both simultaneously, as both are simply aspects of all of our existences and personal experiences of Being-in-the-world.
In a practical sense, our takeaway with this realization should be coupled with another of Sartre’s concepts to be best applied to everyday life: that of Good Faith and authenticity.
You see, when you pick an outfit for a party to either fit in or stand out, you are playing at being something you are not: you are living inauthentically, in Bad Faith. You are playing at being an object, at Being-for-others.
The way to embrace your Being-for-itself is to act authentically, in Good Faith: to pick an outfit true to your Self, what the consciousness of the Other might perceive be damned.
In another of Sartre’s works, his play No Exit, his characters dramatically embody the problem of Being-for-others, and the way that the Other’s perception can distort your sense of Self so severely that you feel you are in Hell.
The paramount quote of the book, spoken by the man Garcin, reads, “Yes, now’s the moment . . . I understand that I’m in hell . . . all those eyes intent on me. Devouring me. What? Only two of you? I thought there were more; many more. So this is hell. I’d never have believed it . . . There’s no need for red-hot pokers. Hell is–other people!” (45).
Garcin had died and gone to Hell, stuck in a room with two women who, in talking with them, understood that his eternal sentence was to become an object of perception for others, a fate more torturous than any for this anxious, self-loathing man.
It’s funny, though––to end the play, Garcin and the women remark how humorous it is that they lived their lives in such a manner that Satan saw it best to confine them with each other and simply have them drive each other insane with their perception of each other.
Garcin’s final line is, “Let’s get on with it.”
And that is exactly what we must do: we must all get on with it. You are a Self with a consciousness that helps you see the world, your Self, and the Other(s) in the world a certain way, and that is enough.
The real freedom in life, whether we be an invisible guest or an object, is that nobody is judging you as severely as you are judging yourself. Nobody is paying nearly as much attention to you as you are paying to yourself.
Good, bad, all of it. Once you realize this, you can stop playing at being a subject, stop playing at being a Self… and simply get on with it and truly be those things.
Thanks for reading.
