What is there left to believe in?: Truth, According to Nietzsche’s “On Truth and Lies in a Nonmoral Sense”
Nietzche brings into question ideas other people don’t usually think twice about, such as “what is truth?” He points out that certain truths are fixed and that language is the conduit with which these “truths” are conveyed. He implies that “fixed truths” are a natural interaction between human beings. As in people are constantly lying to each other (whether they realize it or not). He also points out that “truth is only desired by human beings in a limited sense, they desire the pleasant, life-preserving consequences of truth, they are indifferent to pure knowledge if it has no consequences but they are actually hostile towards truths which may be harmful and destructive” (766). In other words, people like to hear or believe only what they want to. This is correct because people tend to take in only what is convenient to them, if the truth being told is not relevant or convenient to them they don’t absorb it. If the truth has no impact to them then it just passes them by (goes in through one ear and leaves out the other).
Nietzche also explains how language, in particular words, are arbitrary. For example, the words “leaf” and “honest” represent certain concepts but they can’t represent every single leaf out there or every single case of honesty (767). We know for a fact there are countless different leafs and honesty can mean something different for each individual in different scenarios. This ties into epistemology and the question of “how do we know what we know?” Nietzche makes the point that concepts are metaphors which do not correspond to reality. But although metaphors are concepts invented by humans, humans forget this (the fact that they invented them) and come to consider them as “truths.” Then the relationship between these truths and reality forms, and humans get stuck believing in them (forgetting entirely that they were once simply metaphors invented by them). Essentially truth is what we want it to be. Certain truths seem more real or valid because they’ve been around for a long time, but these were once just metaphors. Interestingly, Nietzche goes on to say that language and science are what drive the “truths” people believe in. People tend to accept certain things because they are “scientific truths.” This is an interesting point to make because people do tend to believe blindly in scientific discoveries, theories etc. As if a scientist were never wrong. However, time has shown us that science can definitely be wrong, which leads one to question, if people can’t even believe in the scientific truth then what is there left to believe in?
