Which philosopher is known for the idea that individuals' lives are primarily a quest for power?

The philosopher who is known for the idea that individuals' lives are primarily a quest for power is Thomas Hobbes. Hobbes, in his work "Leviathan," posits that human beings are inherently self-interested and motivated by a desire for power and security. He argues that in a natural state without political authority, life would be "solitary, poor, nasty, brutish, and short," as individuals would constantly compete for resources and power. This recognition of the fundamental drive for power leads Hobbes to advocate for a strong central authority to maintain order and prevent conflict among individuals.

This perspective fundamentally shaped political philosophy and continues to influence discussions about the nature of human behavior, governance, and societal organization.
