Classical Greek philosophy begins in the eastern Mediterranean in the 6th century BC, with the earliest thinkers of the city of Miletus. Along with later figures such as Heraclitus and Parmenides, they are the Pre-Socratics, who put forth pioneering speculations about the natural world, knowledge, and the gods. Things take a more ethical turn with Socrates, with his relentless questioning which challenges other citizens of Athens to give an account of their values. His student Plato, and Plato's student Aristotle, then set the agenda for the rest of the history of philosophy with wide-ranging inquiry into everything from logic and epistemology to beauty, virtue, and myth. This series of episodes concludes with a look at the immediate followers of Plato and Aristotle.
Decades of historical and philological research in the 19th century culminated in 1903 in the epoch-making first comprehensive edition, by Hermann Diels, of the texts (fragments and testimonia) of early Greek philosophy. In its later editions, with revisions and additional material by Walther Kranz (1922-1952), Die Fragmente der Vorsokratiker (often referred to as Diels-Kranz) became the indispensable standard in its particular field, throughout the 20th century and still to this day. But later scholarship and the advent (from the 1970s) of the digital Thesaurus Linguae Graecae made it poignantly evident that a new collection of the texts of the early Greek philosophers would be needed.
Laks and Most are aware of the defects cited in the two preceding paragraphs. And (just as it happened with the early editions of Diels-Kranz), there will be lists of errata in future editions or printings of the Loeb set and of the corresponding French edition by Fayard. In the interim, until such future editions, corrections have now been posted on the academia.edu in the sites, respectively, for Glenn Most (for the Loeb set) and for Andrà Laks (for the French edition).
During the 7th Century BC, philosophy dealt more with natural science rather than moral questions. One of the first Greek philosophers to concentrate on scientific thought was Thales of Miletus. Thales was born around 624 BC in the city of Miletus in Asia Minor and was part of the new wave of thinkers trying to determine how the cosmos was constructed. This was the philosophical branch of metaphysics. Thales was a Monist, meaning that he considered a single element to be the main building block of the cosmos.
He hypothesized that everything in the universe was governed by the principles of mathematics and considered the discipline to be the foundational model for philosophy. He discovered the complex relationships between numbers in the form of proportions and ratios, a line of thinking that was reinforced by his observations of sound and harmonics.
Socrates is one of the most famous Greek philosophers in history, and his thirst for knowledge changed the course of philosophy forever. Socrates was born in 469 BC and he served in the Peloponnesian War. Socrates believed that knowledge was the ultimate good and that pursuing knowledge was vital to living a good, virtuous life. Socrates argued that good and evil were absolute and that only through pursuing knowledge can we learn the difference. To Socrates, ignorance was the ultimate evil.
Plato believed that this contrast between the Ideal Forms and our imperfect copies also applied to concepts such as Goodness and Justice. Plato suggested that using reason to reveal the perfect Form of Goodness, instead of our imperfect copy, was the ultimate purpose of philosophy.
After the death of Alexander the Great, the focus of philosophy moved away from epistemology and metaphysics and instead focused on personal ethics. Philosophical schools sprang up across the Hellenistic World. One of these was The Garden, founded by the Greek philosopher Epicurus.
But being free from social conventions and expectations, Diogenes did not care what others thought of his philosophy. Famously, Alexander the Great sought out Diogenes and asked if there was anything he could do for him. The Cynic merely looked at the young conqueror and requested that he stop blocking his sunlight.

Ancient Greek philosophy is a system of thought, first developed in the 6th century BCE, which was informed by a focus on the First Cause of observable phenomena. Prior to the development of this system by Thales of Miletus (l. c. 585 BCE), the world was understood by the ancient Greeks as having been created by the gods.
These three men initiated the path of inquiry known as ancient Greek philosophy, which was developed by the so-called Pre-Socratic Philosophers, defined as those who engaged in philosophic speculation and the development of different schools of thought from Thales' first efforts up to the time of Socrates of Athens (l. 470/469-399 BCE), who, according to his most famous pupil Plato (l. 424/423-348/347 BCE), enlarged the scope of philosophy to address not only the First Cause but also the individual's moral and ethical obligation to self-improvement for its own sake and the good of the greater community. Plato's work inspired his student Aristotle of Stagira (l. 384-322 BCE) to establish his own school with his own vision based on but significantly different from Plato's own.
Aristotle would go on to become the tutor of Alexander the Great (l. 356-323 BCE) who, through his conquest of Persia, spread the concepts of Greek philosophy throughout the East from the regions of modern-day Turkey up through Iraq and Iran, across through Russia, down to India, and back toward Egypt where it would influence the development of the school of thought known as Neo-Platonism as formulated by the philosopher Plotinus (l. c. 202-274 CE) whose vision, developed from Plato's, of the Divine Mind and a higher reality which informs the observable world would influence that of Paul the Apostle (l. c. 5-64 CE) in his understanding and interpretation of the mission and meaning of Jesus Christ, laying the foundation for Christianity's development.
The works of Aristotle, which would come to inform Christianity as much as Plato's, would also be instrumental in the formulation of Islamic thought after Islam was established in the 7th century CE as well as the theological concepts of Judaism. In the present day, Greek philosophy is the underlying form of belief systems, cultural values, and legal codes all around the world as it has largely contributed to their development.
It has long been established that ancient Greek philosophy begins in the Greek colonies of Ionia along the coast of Asia Minor as the first three Pre-Socratic philosophers all came from Ionian Miletus and the Milesian School is the first Greek philosophical school of thought. The standard explanation as to how Thales first conceived of his philosophy has been the first one cited above. The second theory, however, actually makes more sense in that no school of thought develops in a vacuum and there is nothing in the Greek culture of the 6th century BCE to suggest that intellectual inquiry into the cause of observable phenomena was valued or encouraged.
Scholar G. G. M. James notes that many later philosophers, from Pythagoras to Plato, are said to have studied in Egypt and, in part, to have developed their philosophies there. He suggests that Thales might also have studied in Egypt and established this practice as a tradition others would follow. While this certainly may be the case, there is no documentation to definitively support it while it is known that Thales did study in Babylon. He would have certainly been exposed to Mesopotamian, as well as Egyptian, philosophy in his studies there, and this was most likely the source of his inspiration.
Socrates is considered by some to have been a kind of Sophist, but one who taught freely without expectation of reward. Socrates himself wrote nothing, and all that is known of his philosophy comes from his two students Plato and Xenophon (l. 430 - c. 354 BCE) and the forms his philosophy took in the later philosophic schools founded by his other followers such as Antisthenes of Athens (l. c. 445-365 BCE), Aristippus of Cyrene (l. c. 435-356 BCE), and others.
Aristotle became the tutor of Alexander the Great who would then spread his philosophy, as well as that of his predecessors throughout the world of the Near East and as far as India while, at the same time, Aristotle set up his own school, the Lyceum, in Athens and taught students there. He investigated virtually every area and discipline of human knowledge throughout the rest of his life and was known simply as The Master by later writers.
Not every one of these later thinkers ascribed to his philosophy completely, however, and among these was Plotinus who took the best of Plato's idealism and Aristotle's teleological approach and combined them in the philosophy known as Neo-Platonism, which also contained elements of Indian, Egyptian, and Persian mysticism. In this philosophy, there is an Ultimate Truth - so great that it cannot be comprehended by the human mind - which was never created, can never be destroyed, and cannot even be named; Plotinus called this the nous which translates as Divine Mind.
