Quote by Anaximander: “The Boundless is the origin of existing things.”

Anaximander proposed that the universe originated from an indefinite, primordial substance he called 'The Boundless' or *apeiron*. This idea suggests that all things come from an eternal, unlimited source that encompasses everything before specific forms or elements emerge from it.

Anaximander was among the first pre-Socratic philosophers who sought naturalistic explanations for the cosmos, moving beyond mythological accounts. He theorized a single, infinite source for all existence, rather than a specific element like water or air.

Greek philosopher from Miletus who lived approximately 610–546 BCE, a student of Thales. He is known for developing the concept of the apeiron — an indefinite, boundless source of all things — and for producing one of the earliest known maps of the world. Only a single fragment of his writing survives, quoted by later philosophers.
