045 - Fourth Book The World As Will Second AspectParagraph 71

In this enlightening exploration, Schopenhauer introduces the concept of will, a term that embodies humanitys deepest impulses—desire, striving, wanting, effort, and urging. His philosophy reveals that all of nature, including human existence, is driven by an unquenchable will to life, which paradoxically leads to our suffering. The relentless pursuit of more is the root of this pain. Schopenhauer also delves into the notion of representation (Vorstellung), referring to the mental images we form of objects perceived as separate from our minds. This includes our own bodies, which he termed the immediate object, given its closest connection to our consciousness housed in the brain. (Summary by Wikipedia)
