Now, the most important thing you need to know about Nietzsche is the concept of relativism. I’ll never get tired of saying it: if there is one word that truly needs to be associated with Nietzsche in order to understand him, it’s relativism. Relativism can be defined as the recognition that there is no universal or objective truth. “There are no facts, only interpretations”, Nietzsche wrote. His philosophy fundamentally puts into discussion the existence of any Truth, with a capital T: meaning is inherently subjective and independent, and all notions of good and evil, all set values, are instead discarded. After Nietzsche, then, there will be no more search for a single truth. This may seem almost trivial to you today. But just try thinking about what this concept might have meant to society 200 years ago, where science, religion, politics, education, and more all sought to reveal immutable truths. For example, there was a time where everyone thought that earth was flat: and that was an unquestionable truth, that could not be contested. And it was the same thing with religious beliefs: everyone believed in life after death. Now it is absolutely not the same. And so the very idea of relativism was shocking to society at the time. In a way, relativism is one of the reasons why we might be more tolerant to accept multiple opinions today: for example, we accept that different people believe in different gods. Nietzsche’s introduction of relativism will be his most influential contribution to philosophical thought.
