The idea of freedom in Arthur Schopenhauer (1788-1860) is linked to his philosophy of the will. He outlined his concept of the will in his major works “About the fourfold root of the principle of sufficient reason” (1808) and “The world as will and representation” (1818).
According to Schopenhauer, the will (which I translate as “life force”) is the underlying force driving all human actions, goals and desires.
Schopenhauer defined the will as an insatiable and irrational force that drives human beings towards reproduction and other goals such as success, fame, and wealth accumulation.
From this perspective, individual freedom is influenced by the relentless demands of the will. Humans are pushed to seek the satisfaction of endless desires, leading to inevitable failure and frustration.
