Anaximander

Who was Anaximander?
Anaximander (610–546 BCE) was a pre-Socratic Greek philosopher from Miletus [now in Turkey] who lived in the 6th century BCE. He was the first philosopher to develop a cosmology, or systematic philosophical view, of the world.
Anaximander, a student or associate of Thales, wrote about astronomy, geography, and nature. He introduced the gnomon to Sparta, demonstrating equinoxes, solstices, and possibly hours. He created a world map, later refined by Hecataeus, and may have built a celestial globe. Anaximander posited that the world originated from the apeiron (the infinite or indefinite) and that the Earth was cylindrical and remained in place because it was equidistant from all things.

Where and when did Anaximander live?
Anaximander, a Greek philosopher, was born in Miletus, now in Turkey, in 610 BCE and died in 546 BCE. He is recognized as the first to develop a cosmology, offering a systematic philosophical perspective of the world. Although only a small fragment of Anaximander's work has survived, later Greek writers, such as Aetius, Hippolytus, and Simplicius, reconstructed his philosophy and astronomy. He was a student of Thales of Miletus and wrote about geography, astronomy, and nature. Anaximander used a gnomon at Sparta to demonstrate equinoxes and solstices and drew a map of the known world.

What is Anaximander known for in philosophy?
Anaximander (born 610 BCE) was a Greek philosopher known for developing a cosmology, a systematic philosophical view of the world. He postulated that everything originated from the apeiron (the "infinite" or "indefinite") and that eternal motion, along with the apeiron, was the originating cause of the world. Anaximander also held an evolutionary view of living things, believing that humans originated from other animals.
Additionally, Anaximander is credited with introducing the gnomon to Greece, using it to demonstrate equinoxes and solstices. He also drew a map of the known world.

What is the concept of the 'apeiron' that Anaximander introduced?
Anaximander, a Greek philosopher, introduced the concept of the apeiron (Greek for "unlimited" or "indefinite") as the origin of all things. Rather than a specific element, Anaximander posited the apeiron as an eternal, boundless source, driven by perpetual motion. This motion separates opposites, like hot and cold, leading to the formation of the world. He believed the world isn't eternal and will return to the apeiron, with existing things balancing their injustices in time.

How did Anaximander try to explain the origins of the universe?
Anaximander, a Greek philosopher, posited that everything originated from the apeiron (the "infinite," "unlimited," or "indefinite") rather than a specific element. He suggested eternal motion and the apeiron were the origin of the world. This motion separated opposites, like hot and cold, as the world came into being. Anaximander believed the world isn't eternal and will return to the apeiron, from which new worlds emerge. He also held an evolutionary view of living things, suggesting the first creatures came from the moist element by evaporation and that humans originated from another animal.

In what ways did Anaximander influence later Greek philosophers?
Anaximander, a Greek philosopher, significantly influenced subsequent Greek thinkers through his cosmology and rational explanations of nature. He introduced the concept of the apeiron—an unlimited and indefinite substance—as the origin of all things, differing from his predecessor Thales, who posited water as the primary element.
Anaximander's postulation of eternal motion as the cause of the world's origin and his evolutionary view of living things also had a lasting impact. His efforts to provide a unified, rational account of the world, even though his astronomy was eventually superseded, left a lasting legacy on philosophical thought.

Anaximander (born 610 bce, Miletus [now in Turkey]—died 546 bce) was a Greek philosopher who was the first to develop a cosmology, or systematic philosophical view of the world.
Only a short fragment of Anaximander’s work survives, so reconstructions of his philosophy and astronomy must be based on summaries by later Greek writers, such as the 1st- or 2nd-century ce compiler of philosophical opinions Aëtius, the 3rd-century theologian and antipope Hippolytus, and the 6th-century Neoplatonist philosopher Simplicius. Anaximander is said to have been a pupil or associate of the Greek philosopher Thales of Miletus and to have written about astronomy, geography, and the nature of things. Anaximander set up a gnomon (a shadow-casting rod) at Sparta and used it to demonstrate the equinoxes and solstices and perhaps the hours of the day. He drew a map of the known world, which was later corrected by his fellow Milesian, the author Hecataeus, a well-traveled man. He may also have built a celestial globe.
In his thinking about Earth, he regarded the inhabited portion as flat, consisting of the top face of a cylinder, whose thickness is one-third its diameter. Earth is poised aloft, supported by nothing, and remains in place because it is equidistant from all other things and thus has no disposition to fly off in any one direction. He held that the Sun and the Moon are hollow rings filled with fire. Their disks are vents or holes in the rings, through which the fire can shine. The phases of the Moon, as well as eclipses of the Sun and the Moon, are due to the vents’ closing up.
Anaximander held an evolutionary view of living things. The first creatures originated from the moist element by evaporation. Man originated from some other kind of animal, such as fish, since man needs a long period of nurture and could not have survived if he had always been what he is now. Anaximander also discussed the causes of meteorological phenomena, such as wind, rain, and lightning.
In his cosmogony, he held that everything originated from the apeiron (the “infinite,” “unlimited,” or “indefinite”), rather than from a particular element, such as water (as Thales had held). Anaximander postulated eternal motion, along with the apeiron, as the originating cause of the world. This (probably rotary) motion caused opposites, such as hot and cold, to be separated from one another as the world came into being. However, the world is not eternal and will be destroyed back into the apeiron, from which new worlds will be born. Thus, all existing things must “pay penalty and retribution to one another for their injustice, according to the disposition of time,” as he rather figuratively expressed it.
While Thales had already dispensed with divine explanations of the world around him, he had not written a book about his philosophy. Moreover, Anaximander went much further in trying to give a unified account of all of nature. Although Anaximander’s primitive astronomy was soon superseded, his effort to provide a rational explanation of the world had a lasting influence.
