In the philosophical teachings of Epictetus, a prominent Stoic thinker, it is emphasized that self-interest is a fundamental driving force in the lives of all beings. He asserts that every creature is inherently connected to its own needs and desires, highlighting the universal nature of this truth. This perspective encourages individuals to recognize that self-preservation and personal motivation are core to their actions and decisions.

Epictetus' reflection serves as a reminder to remain realistic about human behavior, underscoring the importance of understanding one's own self-interest. By acknowledging this universal law, individuals can navigate their relationships and interactions more effectively, fostering a deeper awareness of both their motivations and those of others.
