Adam Kadmon - in Greek Philosophy

In Greek Philosophy

The various philosophical views concerning the primal man are, in spite of their differences, intimately related, being a compound of widespread mythology, Greek philosophy, and rabbinical theology. Around the late first century BC, Arius Didymus wrote in Concerning the Opinions of Plato:

Ideas are certain patterns arranged class by class of the things which are by nature sensible, and that these are the sources of the different sciences and definitions. For besides all individual men there is a certain conception of man ... uncreated and imperishable.

And in the same way as many impressions are made of one seal, and many images of one man, so from each single idea of the objects of sense a multitude of individual natures are formed, from the idea of man all men, and in like manner in the case of all other things in nature.

Also the idea is an eternal essence, cause, and principle, making each thing to be of a character such as its own.
