Metaphysics is a branch of philosophy that investigates principles of reality transcending those of any particular science. Cosmology and ontology are traditional branches of metaphysics. It is concerned with explaining the fundamental nature of being and the world. Someone who studies metaphysics would be called either a "metaphysician" or a "metaphysicist."
The word derives from the Greek words μετά (metá) (meaning "beyond" or "after") and φυσικά (physiká) (meaning "physical"), "physical" referring to those works on matter by Aristotle in antiquity. The prefix meta- ("beyond") was attached to the chapters in Aristotle's work that physically followed after the chapters on "physics," in posthumously edited collections. Aristotle himself did not call these works Metaphysics. Aristotle called some of the subjects treated there "first philosophy."
A central branch of metaphysics is ontology, the investigation into what types of things there are in the world and what relations these things bear to one another. The metaphysician also attempts to clarify the notions by which people understand the world, including existence, objecthood, property, space, time, causality, and possibility.
Before the development of modern science, scientific questions were addressed as a part of metaphysics known as "natural philosophy"; the term "science" itself meant "knowledge" of epistemological origin. The scientific method, however, made natural philosophy an empirical and experimental activity unlike the rest of philosophy, and by the end of the eighteenth century it had begun to be called "science" in order to distinguish it from philosophy. Thereafter, metaphysics became the philosophical enquiry of a non-empirical character into the nature of existence.
Esotericism or Esoterism is a term with two basic meanings. In the dictionary sense of the term, "esoterism" signifies the holding of esoteric opinions or beliefs, and derives from the Greek ἐσωτερικός (esôterikos), a compound of ἔσω (esô): "within", thus "pertaining to the more inward", mystic. Its antonym is "exoteric". In scholarly literature, the term designates a series of historically related religious currents including Gnosticism, Hermetism, magic, astrology, alchemy, Rosicrucianism, Vajrayana Buddhism, the Christian Theosophy of Jacob Böhme and his followers, Illuminism, Mesmerism, Swedenborgianism, Spiritualism, and the theosophical currents associated with Helena Blavatsky and her followers. There are competing views regarding the common traits uniting these currents, not all of which involve "inwardness", mystery or secrecy as a crucial trait.
Esoteric knowledge, in the dictionary (non-scholarly) sense, is thus that which is available only to a narrow circle of "enlightened", "initiated", or specially educated people. Esoteric items may be known as esoterica. In contrast, exoteric knowledge is knowledge that is well-known or public; or perceived as informally canonic in society at large.
As a Gnostic, we try to investigate all possiblities and keep an open mind. We are in search of the truth and as time goes on what seems unlikely, science begins to prove. God and Science are one.
