Wittgenstein uses this beetle analogy to suggest that the felt states and sensations that occur in a person’s mind; things like smell, pain, love, happiness, sadness, and so on are things that no one can communicate sufficiently enough to share and reveal their experiences to others. I can never see your beetle, and you can never see mine. When we attempt to think and communicate about the beetle, though, the word has to be a word that everyone understands and can be taught for the word to have any meaning. According to Wittgenstein and many others, language is entirely social. This theory is known as the Private Language Argument, which proposes that no language can be understandable if it is solely to one individual. Rather, language is only formed through shared use amongst a community of others. Thus, the sensation of something might exist exclusively to one’s self, but it can never be understood in terms of language exclusively to one’s self. Meaning, we can never know if anyone experiences anything the same way we experience it, even if everyone talks about it in the same words. We can only assume. Arguably, trying to rationalize, communicate, and comprehend the mental experience of a sensation as it actually is, becomes inconceivable after a certain point. For example, one could say that fresh cut grass smells good, but when asked what it smells like, they would have to go on to say things like it smells natural or like the season of spring. If then asked, what that smells like, perhaps if one tried hard enough, they could come with a few other smells to compare it to, but they would eventually and inevitably reach the limits of language. There would be a final question of what it smells like that would have no answer. A sensation beyond words that no one besides the smeller could know for sure what is like. “Whereof one cannot speak, thereof one must be silent.” Wittgenstein writes when referring to the notion of subjective experience and that which exceeds language and logical understanding. Beyond the suggestions of language and shared meaning, arguably what is most thought-provoking about all of this is the notion that we can never know what it feels like to be anyone else other than our self. We can never know what the world might look, taste, smell, sound, and feel like from outside our own heads. We can never verify what anyone else’s color blue looks like, or what anyone else’s punch in the arm feels like, or what anyone else’s sense of love or happiness is like. We are all locked inside our minds, yelling out to each other in an attempt to find out, but never capable of entering anyone else’s to find out for sure. Even if the framework, structure, and wiring of each of our brains are mostly identical, the unknowable conscious psychological layer on top of it all transmutes the experience of neurological occurrences into something abstract, distanced enough from the measurable and communicable to ever know exactly what any of it is, where it comes from, and how it might change in different heads. Ultimately, no matter the philosophical stance or scientific theory, it is fair to argue that at a minimum no one can or will ever know what it means to have navigated and experienced this universe in the way that you have and will. Each moment that you experience, a particular sense or image of the world with your particular conditions of consciousness, is forever yours exclusively, withholding the mystery of what it means to actually be you for all of eternity. Perhaps we all feel and experience in nearly identical ways, or perhaps we all feel and experience in very dissimilar ways. Your version of blue, your sensation of pain, your experience of love, could perhaps be its only version of blue, its only version of pain, and its only version of love to ever exist in the entire universe. The point is, we don’t know because each of us holds the answer that no one can ever access.
