His writings, which survived into the Hellenistic Ageno longer exist except in passages in the works of later authors. Consequently, interpretations of his beliefs are frequently in conflict.
Pythagorean theorem There are two theorems of Thales in elementary geometryone known as Thales' theorem having to do with a triangle inscribed in a circle and having the circle's diameter as one leg, the other theorem being also called the intercept theorem.
In addition Eudemus attributed to him the discovery that a circle is bisected by its diameter, that the base angles of an isosceles triangle are equal and that vertical angles are equal.
According to a historical Note,  when Thales visited Egypthe observed that whenever the Egyptians drew two intersecting lines, they would measure the vertical angles to make sure that they were equal.
Thales concluded that one could prove that all vertical angles are equal if one accepted some general notions such as: Aristotle laid out his own thinking about matter and form which may shed some light on the ideas of Thales, in Metaphysics b6 8—11, 17— The passage contains words that were later adopted by science with quite different meanings.
That from which is everything that exists and from which it first becomes and into which it is rendered at last, its substance remaining under it, but transforming in qualities, that they say is the element and principle of things that are. Thales the founder of this type of philosophy says that it is water.
In this quote we see Aristotle's depiction of the problem of change and the definition of substance. He asked if an object changes, is it the same or different?
In either case how can there be a change from one to the other? Aristotle conjectured that Thales reached his conclusion by contemplating that the "nourishment of all things The life and philosophical thoughts of thales moist and that even the hot is created from the wet and lives by it.
Thales thought the Earth must be a flat disk which is floating in an expanse of water. It seems likely that Thales viewed the Earth as solidifying from the water on which it floated and the oceans that surround it. The book Dictionary of Greek and Roman Biography and Mythology noted  Thales dogma that water is the origin of things, that is, that it is that out of which every thing arises, and into which every thing resolves itself, Thales may have followed Orphic cosmogonies, while, unlike them, he sought to establish the truth of the assertion.
Hence, Aristotle, immediately after he has called him the originator of philosophy brings forward the reasons which Thales was believed to have adduced in confirmation of that assertion; for that no written development of it, or indeed any book by Thales, was extant, is proved by the expressions which Aristotle uses when he brings forward the doctrines and proofs of the Milesian.
Historian Abraham Feldman holds this does not stand up under closer examination. In Babylonian religion the water is lifeless and sterile until a god acts upon it, but for Thales water itself was divine and creative.
He maintained that "All things are full of gods", and to understand the nature of things was to discover the secrets of the deities, and through this knowledge open the possibility that one could be greater than the grandest Olympian.
He certainly handled the shell-fish of the Phoenicians that secreted the dye of imperial purple. Rather than seeing water as a barrier Thales contemplated the Ionian yearly religious gathering for athletic ritual held on the promontory of Mycale and believed to be ordained by the ancestral kindred of Poseidon, the god of the sea.
He called for the Ionian mercantile states participating in this ritual to convert it into a democratic federation under the protection of Poseidon that would hold off the forces of pastoral Persia.
Feldman concludes that Thales saw "that water was a revolutionary leveler and the elemental factor determining the subsistence and business of the world"  and "the common channel of states. He would have seen that minerals could be processed from water such as life-sustaining salt and gold taken from rivers.
Feldman points out that Thales held that the lodestone was alive as it drew metals to itself. He holds that Thales "living ever in sight of his beloved sea" would see water seem to draw all "traffic in wine and oil, milk and honey, juices and dyes" to itself, leading him to "a vision of the universe melting into a single substance that was valueless in itself and still the source of wealth.
The social significance of water in the time of Thales induced him to discern through hardware and dry-goods, through soil and sperm, blood, sweat and tears, one fundamental fluid stuff Neopythagoreanism and Neoplatonism Thales applied his method to objects that changed to become other objects, such as water into earth or so he thought.
Thales also applied his method to the act of change itself, approaching it through lodestone and amber which, when electrified by rubbing together, also attracts.
The lodestone and the amber must be alive, and if that were so, there could be no difference between the living and the dead. The idea did not originate with him, as the Greeks in general believed in the distinction between mind and matter, which was ultimately to lead to a distinction not only between body and soul but also between matter and energy.
This belief was no innovation, as the ordinary ancient populations of the Mediterranean did believe that natural actions were caused by divinities. Accordingly, Aristotle and other ancient writers state that Thales believed that "all things were full of gods.
Zeus was the very personification of supreme minddominating all the subordinate manifestations. From Thales on, however, philosophers had a tendency to depersonify or objectify mind, as though it were the substance of animation per se and not actually a god like the other gods.
The end result was a total removal of mind from substance, opening the door to a non-divine principle of action. Instead of referring to the person, Zeus, they talked about the great mind:The translation of The Hymns to Amun is part of my Ancient Egyptian Readings (), a POD publication in paperback format of all translations available at ashio-midori.com readings span a period of thirteen centuries, covering all important stages of Ancient Egyptian literature.
