Patricia F. O'Grady is an Australian historian of philosophy specializing in ancient Greek philosophy and in particular on Thales of Miletus. She earned a doctorate in 1998 at Flinders University, with the dissertation Thales: Some Problems in Early Greek Science and Philosophy. [1]

Her books include:

She was the author of the first book to cover Thales, [5] although another has subsequently appeared. [6] Some of her claims about Thales have been controversial. One of these concerns Thales' prediction of the eclipse of Thales in May 585 BCE. Following Bartel Leendert van der Waerden, O'Grady suggested that Thales could have predicted this solar eclipse through its occurrence 23 1/2 months after a lunar eclipse, using Mesopotamian data on prior eclipses. However, although David Sherry finds this theory convincing, [7] it has been disputed by Dirk L. Couprie, who argued against the possibility of making the prediction in this way and provided an alternative theory. [8] Another of these claims concerns a passage in Aristotle stating that Thales described the Earth as floating on water. The consensus of scholars is that Thales thought that the world was flat, and floats like a leaf or a raft on a flat ocean, but O'Grady takes the non-standard and disputed position that Thales thought of the Earth as a sphere surrounded by space, with its land masses ("earth", using the same word as Earth in ancient Greek as one does in English) floating on its oceans, and that Thales was misinterpreted by Aristotle.

Anaximander Pre-Socratic Ionian philosopher

Anaximander was a pre-Socratic Greek philosopher who lived in Miletus, a city of Ionia. 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.

Anaximenes of Miletus Ancient Greek Pre-Socratic philosopher

Anaximenes of Miletus was an Ancient Greek, Ionian Pre-Socratic philosopher from Miletus in Asia Minor, active in the latter half of the 6th century BC. The details of his life are obscure because none of his work has been preserved. Anaximenes' ideas are only known today because of comments about him made by later writers, such as Aristotle.

Thales of Miletus Ancient Greek philosopher and mathematician

Thales of Miletus was a Greek mathematician, astronomer and pre-Socratic philosopher from Miletus in Ionia, Asia Minor. He was one of the Seven Sages of Greece. Many, most notably Aristotle, regarded him as the first philosopher in the Greek tradition, and he is otherwise historically recognized as the first individual known to have entertained and engaged in scientific philosophy. He is often referred to as the Father of Science.

Pre-Socratic philosophy, also known as early Greek philosophy, is ancient Greek philosophy before Socrates. Pre-Socratic philosophers were mostly interested in cosmology, the beginning and the substance of the universe, but the inquiries of these early philosophers spanned the workings of the natural world as well as human society, ethics, and religion. They sought explanations based on natural law rather than the actions of gods. Their work and writing has been almost entirely lost. Knowledge of their views comes from testimonia, i.e. later authors' discussions of the work of pre-Socratics. Philosophy found fertile ground in the ancient Greek world because of the close ties with neighboring civilizations and the rise of autonomous civil entities, poleis.

A sophist was a teacher in ancient Greece in the fifth and fourth centuries BC. Sophists specialized in one or more subject areas, such as philosophy, rhetoric, music, athletics, and mathematics. They taught arete – "virtue" or "excellence" – predominantly to young statesmen and nobility.

A specialist in the philosophical alloying of science and religion, for over thirty years he held university positions in North America, Europe, and Russia.

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 BCE. This movement began on the Ionian coast of western Anatolia by small numbers of forward-thinking Greeks 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.
