The Secret Doctrines (The School of the Initiates)
There was a resurgence of esotericism in the 20th century -pagan beliefs-, and these societies flourished in France, England and the United States -mainly-, where the first revolutionary antecedents emerged that would shape the future mixture of beliefs that corporations had prepared to transcend religion and science. The word esotericism comes from the Greek esoterikos. From the prefix eso- (within), the comparative suffix -eros (interiority), and the suffix -ic (relating to). Therefore, esoteric would mean to go inward. For the philosopher Aristotle, esoteric referred to very complex philosophies that only the wise could understand -those who look inward-. In contrast, the term exoteric exists -towards the outside of interiority-, referring to simple philosophies that anyone from outside could understand. In Ancient Greece, the term esoteric referred to teachings learned exclusively within schools -or in secret societies-, while exoteric referred to teachings of the street. Since ancient times, priests have jealously guarded knowledge, and many teachings were reserved for a select number of people -ignorant-. While others were maintained in secret groups -elites-. It is said that all the wise philosophers of Greece imparted a double education:
The knowledge of those who listened to their talks and read their dialogues. The knowledge learned within their schools -initiates-.
