Milesian school

The Milesian school (/maɪˈliːʃiən, -ʃən/) was a school of thought founded in the 6th century BC. The ideas associated with it are exemplified by three philosophers from the Ionian town of Miletus, on the Aegean coast of Asia Minor: Thales, Anaximander, and Anaximenes. They introduced new opinions contrary to the prevailing belief of how the world was organized, in which natural phenomena were explained solely by the will of anthropomorphized gods. The Milesians conceived of nature in terms of methodologically observable entities, and as such was one of the first truly scientific philosophies.

The Milesian school is not synonymous with the Ionian, which includes the philosophies of the Milesians plus distinctly different Ionian thinkers such as Heraclitus. The Ionian School contains the three philosophers that form the Milesian School as well as a few more who were added on during the 5th Century, but the Ionian School looked more into the thought behind everything while the Milesian School was more focused on nature.[1]

548 BC

The year 548 BC was a year of the pre-Julian Roman calendar. In the Roman Empire, it was known as year 206 Ab urbe condita. The denomination 548 BC for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Absolute (philosophy)

In philosophy, the concept of The Absolute, also known as The (Unconditioned) Ultimate, The Wholly Other, The Supreme Being, The Absolute/Ultimate Reality, and other names, is the thing, being, entity, power, force, reality, presence, law, principle, etc. that possesses maximal ontological status, existential ranking, existential greatness, or existentiality. In layman's terms, this is the one that is, in one way or another, the greatest, truest, or most real being.

There are many conceptions of The Absolute in various fields and subjects, such as philosophy, religion, spiritual traditions, mathematics, and even natural science. The nature of these conceptions can range from "merely" encompassing all physical existence, nature, or reality, to being completely unconditioned existentially, transcending all concepts, notions, and types, kinds, and categories of being.

The Absolute is often thought of as causing to come into being manifestations that interact with lower or lesser forms of being. This is either done passively, through emanations, or actively, through avatars and incarnations. These existential manifestations, which themselves can possess transcendent attributes, only contain minuscule or infinitesimal portions of the true essence of The Absolute.

The term itself was not in use in ancient or medieval philosophy, but closely related to the description of God as Actus purus (Pure Actuality) in scholasticism. It was introduced in modern philosophy, notably by Hegel, for "the sum of all being, actual and potential".

The term has since also been adopted in perennial philosophy.

Amistad Onus

Amistad Onus (Translated from the Latin to: "Alliance Load" or "Friend Load") is the Latin name of a Tax that was famously first implemented by the Milesian school. The practice was quickly spread as students of the Milesian school became scholars themselves, and by 318 BC it was a common practice amongst many Greek schools and tutors.


Anaxagoras (; Greek: Ἀναξαγόρας, Anaxagoras, "lord of the assembly"; c. 510 – c. 428 BC) was a Pre-Socratic Greek philosopher. Born in Clazomenae at a time when Asia Minor was under the control of the Persian Empire, Anaxagoras came to Athens. According to Diogenes Laërtius and Plutarch, in later life he was charged with impiety and went into exile in Lampsacus; the charges may have been political, owing to his association with Pericles, if they were not fabricated by later ancient biographers.Responding to the claims of Parmenides on the impossibility of change, Anaxagoras described the world as a mixture of primary imperishable ingredients, where material variation was never caused by an absolute presence of a particular ingredient, but rather by its relative preponderance over the other ingredients; in his words, "each one is... most manifestly those things of which there are the most in it". He introduced the concept of Nous (Cosmic Mind) as an ordering force, which moved and separated out the original mixture, which was homogeneous, or nearly so.

He also gave a number of novel scientific accounts of natural phenomena. He produced a correct explanation for eclipses and described the sun as a fiery mass larger than the Peloponnese, as well as attempting to explain rainbows and meteors.


Anaximander (; Greek: Ἀναξίμανδρος Anaximandros; c. 610 – c. 546 BC) was a pre-Socratic Greek philosopher who lived in Miletus, a city of Ionia (in modern-day Turkey). He belonged to the Milesian school and learned the teachings of his master Thales. He succeeded Thales and became the second master of that school where he counted Anaximenes and, arguably, Pythagoras amongst his pupils.Little of his life and work is known today. According to available historical documents, he is the first philosopher known to have written down his studies, although only one fragment of his work remains. Fragmentary testimonies found in documents after his death provide a portrait of the man.

He was an early proponent of science and tried to observe and explain different aspects of the universe, with a particular interest in its origins, claiming that nature is ruled by laws, just like human societies, and anything that disturbs the balance of nature does not last long. Like many thinkers of his time, Anaximander's philosophy included contributions to many disciplines. In astronomy, he attempted to describe the mechanics of celestial bodies in relation to the Earth. In physics, his postulation that the indefinite (or apeiron) was the source of all things led Greek philosophy to a new level of conceptual abstraction. His knowledge of geometry allowed him to introduce the gnomon in Greece. He created a map of the world that contributed greatly to the advancement of geography. He was also involved in the politics of Miletus and was sent as a leader to one of its colonies.

Ancient Greek philosophy

Ancient Greek philosophy arose in the 6th century BC and continued throughout the Hellenistic period and the period in which Ancient Greece was part of the Roman Empire. Philosophy was used to make sense out of the world in a non-religious way. It dealt with a wide variety of subjects, including astronomy, mathematics, political philosophy, ethics, metaphysics, ontology, logic, biology, rhetoric and aesthetics.Greek philosophy has influenced much of Western culture since its inception. Alfred North Whitehead once noted: "The safest general characterization of the European philosophical tradition is that it consists of a series of footnotes to Plato". Clear, unbroken lines of influence lead from ancient Greek and Hellenistic philosophers to Early Islamic philosophy, the European Renaissance and the Age of Enlightenment.Some claim that Greek philosophy was in turn influenced by the older wisdom literature and mythological cosmogonies of the ancient Near East, though this is debated. Martin Litchfield West gives qualified assent to this view by stating that "contact with oriental cosmology and theology helped to liberate the early Greek philosophers' imagination; it certainly gave them many suggestive ideas. But they taught themselves to reason. Philosophy as we understand it is a Greek creation".Subsequent philosophic tradition was so influenced by Socrates as presented by Plato that it is conventional to refer to philosophy developed prior to Socrates as pre-Socratic philosophy. The periods following this, up to and after the wars of Alexander the Great, are those of "classical Greek" and "Hellenistic" philosophy.

In Western philosophy, the spread of Christianity in the Roman Empire marked the ending of Hellenistic philosophy and ushered in the beginnings of Medieval philosophy, whereas in Eastern philosophy, the spread of Islam through the Arab Empire marked the end of Old Iranian philosophy and ushered in the beginnings of early Islamic philosophy.

Colonies in antiquity

Colonies in antiquity were post-Iron Age city-states founded from a mother-city (its "metropolis"), not from a territory-at-large. Bonds between a colony and its metropolis remained often close, and took specific forms during the period of classical antiquity. Generally, colonies founded by the ancient Phoenicians, Carthage, Rome, Alexander the Great and his successors remained tied to their metropolis, but Greek colonies of the Archaic and Classical eras were sovereign and self-governing from their inception. While Greek colonies were often founded to solve social unrest in the mother-city, by expelling a part of the population, Hellenistic, Roman, Carthaginian, and Han Chinese colonies were used for expansion and empire-building.


Hylozoism is the philosophical point of view that matter is in some sense alive. The concept dates back at least as far as the Milesian school of pre-Socratic philosophers. The term was introduced to English by Ralph Cudworth in 1678.

Ionian Enlightenment

The Ionian Enlightenment was a set of advances in scientific thought, explanations on nature, and discovering the natural and rational causes behind observable phenomena, that took place in archaic Greece beginning in the 6th century BC. This movement began on the Ionian coast of western Anatolia by small numbers of forward-thinking Greeks (see Ionian School and Milesian School) from cities such as Miletus, Samos, and Halicarnassus. They saw the world as something ordered and intelligible, its history following an explicable course and its different parts arranged in a comprehensible system. Most historians agree that Thales, one of the Seven Sages of Greece, started this movement by predicting a solar eclipse that actually occurred, though some believe this feat to be false.

Ionian School (philosophy)

The Ionian school of Pre-Socratic philosophy was centred in Miletus, Ionia in the 6th century BC. Miletus and its environs was a thriving mercantile melting pot of current ideas of the time. The Ionian School included such thinkers as Thales, Anaximander, Anaximenes, Heraclitus, Anaxagoras, and Archelaus. The collective affinity of this group was first acknowledged by Aristotle who called them physiologoi (φυσιολόγοι), meaning 'those who discoursed on nature'. The classification can be traced to the second-century historian of philosophy Sotion. They are sometimes referred to as cosmologists, since they were largely physicalists who tried to explain the nature of matter.

While some of these scholars are included in the Milesian school of philosophy, others are more difficult to categorize.

Most cosmologists thought that, although matter could change from one form to another, all matter had something in common which did not change. They did not agree on what all things had in common, and did not experiment to find out, but used abstract reasoning rather than religion or mythology to explain themselves, thus becoming the first philosophers in the Western tradition.

Later philosophers widened their studies to include other areas of thought. The Eleatic school, for example, also studied epistemology, or how people come to know what exists. But the Ionians were the first group of philosophers that we know of, and so remain historically important.

Miletus (; Ancient Greek: Μίλητος, translit. Milētos; Hittite transcription Millawanda or Milawata (exonyms); Latin: Miletus; Turkish: Milet) was an ancient Greek city on the western coast of Anatolia, near the mouth of the Maeander River in ancient Caria. Its ruins are located near the modern village of Balat in Aydın Province, Turkey. Before the Persian invasion in the middle of the 6th century BC, Miletus was considered the greatest and wealthiest of Greek cities.Evidence of first settlement at the site has been made inaccessible by the rise of sea level and deposition of sediments from the Maeander. The first available evidence is of the Neolithic.

In the early and middle Bronze age the settlement came under Minoan influence. Legend has it that an influx of Cretans occurred displacing the indigenous Leleges. The site was renamed Miletus after a place in Crete.

The Late Bronze Age, 13th century BC, saw the arrival of Luwian language speakers from south central Anatolia calling themselves the Carians. Later in that century other Greeks arrived. The city at that time rebelled against the Hittite Empire. After the fall of that empire the city was destroyed in the 12th century BC and starting about 1000 BC was resettled extensively by the Ionian Greeks. Legend offers an Ionian foundation event sponsored by a founder named Neleus from the Peloponnesus.

The Greek Dark Ages were a time of Ionian settlement and consolidation in an alliance called the Ionian League. The Archaic Period of Greece began with a sudden and brilliant flash of art and philosophy on the coast of Anatolia. In the 6th century BC, Miletus was the site of origin of the Greek philosophical (and scientific) tradition, when Thales, followed by Anaximander and Anaximenes (known collectively, to modern scholars, as the Milesian School) began to speculate about the material constitution of the world, and to propose speculative naturalistic (as opposed to traditional, supernatural) explanations for various natural phenomena.

Miletus is the birthplace of the Hagia Sophia's architect (and inventor of the flying buttress) Isidore of Miletus and Thales, a pre-Socratic Greek philosopher (and one of the Seven Sages of Greece) in c. 624 BC.

Natural philosophy

Natural philosophy or philosophy of nature (from Latin philosophia naturalis) was the philosophical study of nature and the physical universe that was dominant before the development of modern science. It is considered to be the precursor of natural science.

From the ancient world, starting with Aristotle, to the 19th century, natural philosophy was the common term for the practice of studying nature. It was in the 19th century that the concept of "science" received its modern shape with new titles emerging such as "biology" and "biologist", "physics" and "physicist" among other technical fields and titles; institutions and communities were founded, and unprecedented applications to and interactions with other aspects of society and culture occurred. Isaac Newton's book Philosophiae Naturalis Principia Mathematica (1687), whose title translates to "Mathematical Principles of Natural Philosophy", reflects the then-current use of the words "natural philosophy", akin to "systematic study of nature". Even in the 19th century, a treatise by Lord Kelvin and Peter Guthrie Tait, which helped define much of modern physics, was titled Treatise on Natural Philosophy (1867).

In the German tradition, Naturphilosophie (philosophy of nature) persisted into the 18th and 19th century as an attempt to achieve a speculative unity of nature and spirit. Some of the greatest names in German philosophy are associated with this movement, including Goethe, Hegel and Schelling. Naturphilosophie was associated with Romanticism and a view that regarded the natural world as a kind of giant organism, as opposed to the philosophical approach of figures such as John Locke and Isaac Newton who espoused a more mechanical view of the world, regarding it as being like a machine.

Pre-Socratic philosophy

A number of early Greek philosophers active before and during the time of Socrates are collectively known as the pre-Socratics. Their inquiries spanned the workings of the natural world as well as human society, ethics, and religion, seeking explanations based on natural principles rather than the actions of supernatural gods. They introduced to the West the notion of the world as a kosmos, an ordered arrangement that could be understood via rational inquiry.In Classical antiquity, the pre-Socratic philosophers were called physiologoi (Greek: φυσιολόγοι; in English, physical or natural philosophers). Aristotle was the first to make a clear distinction between these physiologoi or physikoi ("physicists", after physis, "nature") who sought natural explanations for phenomena, and the earlier theologoi (theologians), or mythologoi (story tellers and bards) who attributed these phenomena to various gods. Diogenes Laërtius divides the physiologoi into two groups: Ionian, led by Anaximander, and the Italiote, led by Pythagoras.


Science (from the Latin word scientia, meaning "knowledge") is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.The earliest roots of science can be traced to Ancient Egypt and Mesopotamia in around 3500 to 3000 BCE. Their contributions to mathematics, astronomy, and medicine entered and shaped Greek natural philosophy of classical antiquity, whereby formal attempts were made to explain events of the physical world based on natural causes. After the fall of the Western Roman Empire, knowledge of Greek conceptions of the world deteriorated in Western Europe during the early centuries (400 to 1000 CE) of the Middle Ages but was preserved in the Muslim world during the Islamic Golden Age. The recovery and assimilation of Greek works and Islamic inquiries into Western Europe from the 10th to 13th century revived natural philosophy, which was later transformed by the Scientific Revolution that began in the 16th century as new ideas and discoveries departed from previous Greek conceptions and traditions. The scientific method soon played a greater role in knowledge creation and it was not until the 19th century that many of the institutional and professional features of science began to take shape.Modern science is typically divided into three major branches that consist of the natural sciences (e.g., biology, chemistry, and physics), which study nature in the broadest sense; the social sciences (e.g., economics, psychology, and sociology), which study individuals and societies; and the formal sciences (e.g., logic, mathematics, and theoretical computer science), which study abstract concepts. There is disagreement, however, on whether the formal sciences actually constitute a science as they do not rely on empirical evidence. Disciplines that use existing scientific knowledge for practical purposes, such as engineering and medicine, are described as applied sciences.Science is based on research, which is commonly conducted in academic and research institutions as well as in government agencies and companies. The practical impact of scientific research has led to the emergence of science policies that seek to influence the scientific enterprise by prioritizing the development of commercial products, armaments, health care, and environmental protection.

Timeline of Western philosophers

This is a list of philosophers from the Western tradition of philosophy.


Vitalism is the belief that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things".a Where vitalism explicitly invokes a vital principle, that element is often referred to as the "vital spark", "energy" or "élan vital", which some equate with the soul. In the 18th and 19th centuries vitalism was discussed among biologists, between those who felt that the known mechanics of physics would eventually explain the difference between life and non-life and vitalists who argued that the processes of life could not be reduced to a mechanistic process. Some vitalist biologists proposed testable hypotheses meant to show inadequacies with mechanistic explanations, but these experiments failed to provide support for vitalism. Biologists now consider vitalism in this sense to have been refuted by empirical evidence, and hence regard it as a superseded scientific theory.Vitalism has a long history in medical philosophies: many traditional healing practices posited that disease results from some imbalance in vital forces.
