Will to life
The will to live (German: der Wille zum Leben) is a concept developed by the German philosopher Arthur Schopenhauer, representing an irrational "blind incessant impulse without knowledge" that drives instinctive behaviors, causing an endless insatiable striving in human existence. This is contrasted with the concept of the will to survive under life threatening conditions used in psychology since Schopenhauer's notion of the will to live is more broadly understood as the "animal[istic] force to endure, reproduce and flourish".
