We Think We Know, But Oh How We Don’t: Nietzsche’s “On Truth and Lying in a Non-Moral Sense”
Overall, this reading was honestly depressing. As humans, we think we know things and we think we understand how the world works but we do not. Nietzsche brings up many points and concepts that I usually do not think about because, simply put, it is scary. He questions many things like whether or not humans can really know anything at all, even about humans. “What do human beings really know about themselves? Are they even capable of perceiving themselves in their entirety just once, stretched out an in an illuminated glass case?” Anything we know is through the lens of human interpretation so in reality do we know the truth about anything? How can we if we can not remove the lens of human interpretation to make our observations purely objective? Everything we know and think we know about the world is really just the human interpretation of something that is not remotely human, it is something clearly larger and tremendously more complex than we can ever fully comprehend. It can be said that this is why humans believe in things like religion. We need an order to things so that we feel safe and we need direction and guidance to feel like we are living meaningful lives. By believing in a higher power such as god, it can give a sense of security and a feeling of safety as we go through life. It is easier to go through life believing things happen because they are “meant to be” or because “god has a plan” rather than just because of chance.
Nietzsche explains another way we can realize that there is no truth is by looking at something like a bird in comparison to ourselves. If one was asked who has a better understanding of the world- a bird or human, almost everyone would probably say a human without any hesitation. However, why is that true? We understand the world from a humans perspective and to us that seems to be the truest truth but maybe it is the bird who has a better understanding of the world. They see humans for what we are on our most basic level- a species- and maybe it is foolish to believe we are anything more.
Another way Nietzsche proves that there is just no truth, is by using the example of language. Language is a series of metaphors that we use to label and categorize everything so that we have order. “What is a word? The copy of nervous stimulations in sounds.” He goes on to give the example, “The stone is hard’, as if ‘hard’ were something known to us in some other way, and not merely as an entirely subjective stimulus?” This shows that even something as crucial to human life as language, what we rely on as a truth to communicate with one another, is flawed. It is subjective- everything is. “We believe that when we speak of trees, colors, snow and flowers, we have knowledge of the things themselves, and yet we possess only metaphors of things which in no way correspond to the original entities.” We create concepts and truths that make sense to us and we build on these over time. But in reality, nothing is true because what even is truth? There is a quote from the Broadway musical Wicked that states “The truth isn’t a thing of fact, or reason. It’s simply what everyone agrees on.” This quote is frighteningly accurate and in my opinion directly ties in to what Nietzsche’s whole point is: we think we know, but oh how we don’t.
