Unmoved mover

Definition

The unmoved mover is a fundamental concept in Aristotle's philosophy, referring to an ultimate cause or source of motion that itself is not subject to change or movement. This idea posits that everything in motion must have been set in motion by something else, leading to the conclusion that there must be a first cause that itself is uncaused. The unmoved mover is essential in understanding Aristotle's metaphysics and theology, as it underlines his belief in a necessary being that initiates all actions and changes in the universe without being influenced by anything else.

Review Questions

• How does Aristotle's concept of the unmoved mover explain the existence of change and motion in the world?
  • Aristotle’s concept of the unmoved mover explains change and motion by asserting that every motion has to originate from a prior cause. This leads to the conclusion that there must be an initial source of movement that itself remains unchanged. Without this unmoved mover, there would be an infinite regression of causes, which Aristotle argues is logically untenable. Hence, this first cause is essential for establishing the existence of motion in the universe.
• Discuss the relationship between the unmoved mover and Aristotle's understanding of substance and essence.
  • The unmoved mover is intricately connected to Aristotle's notions of substance and essence. The unmoved mover represents pure actuality, embodying what it means to be a substance without potentiality for change. In contrast, other substances exist in a state of potentiality until they realize their essence through action. Thus, while substances may undergo change, the unmoved mover remains constant and serves as the ultimate reference point for defining both substance and essence within his metaphysical framework.
• Evaluate how the idea of the unmoved mover impacts Aristotle's views on divinity and its role in the cosmos.
  • The idea of the unmoved mover significantly shapes Aristotle's views on divinity as it establishes God as a necessary being who initiates all movement without undergoing any change itself. This conception influences his understanding of divine intelligence; God exists as an object of desire for all beings, drawing them towards their purpose and perfection. By positing God as the unmoved mover, Aristotle integrates theology with metaphysics, suggesting that divine influence operates throughout the cosmos while remaining unaltered by it, thus shaping a coherent philosophical system.
