Philosophy is derived from the Greek word philosophia (meaning a love of wisdom) and is a broad term for human understanding of existence, with headings of;
- metaphysics: deals with existence, identity, space, time, causality
- ethics: addresses questions about justice and morality.
- logic: the study of the principles of reasoning.
- epistemology: based on the Greek words “episteme” (meaning knowledge) and “logos” (meaning account/explanation) – epistemology addresses the questions, “What is knowledge?”
- spiritual/religious: deals with what people believe, particularly in the area of a higher power or God
- aesthetics: concerned with the nature and appreciation of art, beauty and good taste.
- perception : concerned with the nature of perceptual experience and the status of perceptual data, in particular how they relate to beliefs about, or knowledge of, the world.
Many of these philosophies deal with the issue of mind-matter interaction, and science today also is dealing with the same issues, due to the emergence of Quantum physics.
Spiritual philosophy, particularly the understanding of mind-matter interaction such as creativity, spirit/intuition, God/Higher Power relevance and universal consciousness, is a broad subject of millions of books. However there are several useful introductory philosophical terms and concepts worth understanding, including pantheism, monism, panpsychism, Ietsism, Existentialisim and panentheism.
Aldous Huxley defined philosophy as ; “The metaphysic that recognizes a divine Reality substantial to the world of things and lives and minds; the psychology that finds in the soul something similar to, or even identical with, divine Reality, and the ethic that places man’s final end in the knowledge of the immanent and transcendent Ground of all being.”
