What philosophical issue does Aristotle tackle with the concept of the Prime Mover?

The concept of the Prime Mover is central to Aristotle's metaphysics and addresses the nature of reality and existence. The Prime Mover is an essential aspect of Aristotle's explanation of the universe's existence and order. He posits that there must be a first cause, an uncaused cause, which initiates the motion and change in the universe without itself being moved. This allows for a coherent explanation of how change occurs while avoiding an infinite regress of causes.

In this context, the Prime Mover serves to explain the existence of the universe by positing a necessary being that is the ultimate source of all reality. This connects deeply with discussions about the nature of being, causation, and existence itself, as it seeks to establish a foundation for understanding everything that exists.

While the other issues raised in the options, such as empirical observation, the problem of evil, and contradictions within Platonic thought, hold significant philosophical importance, they do not directly engage with the metaphysical inquiries surrounding the existence and nature of reality that Aristotle addresses through the concept of the Prime Mover.
