"And since all things have been named light and night and things corresponding to their powers for each, everything is full alike of light and invisible night, both equal since nothing has a share in neither"

This quote by Parmenides speaks about the concept of light and night, and how everything in the world includes both elements in equal step. The philosopher argues that light and darkness are not mutually special, however rather exist side-by-side within every element of existence. He recommends that these aspects are not just physical attributes, but likewise represent the forces of power and energy within whatever around us. According to Parmenides, nothing on the planet can exist without these fundamental forces, and they are equally important and present in all things. This quote points towards the balance in between light and darkness worldwide, and the necessity of both for life to thrive.
