An acronym standing for "Infinite Diversity in Infinite Combination", the way of IDIC is the central thesis of the Vulcan Science Academy. Vulcan doctrines of the soul and the reality of the spiritual infuse the concept of IDIC as well; the Vulcan Science Academy has well respected schools of theology, philosophy, and arts. Everything that is or that can be conceived of is part of the Truth; diminishing one aspect of Truth to conform to bias or prejudice or for any other reason is illogical. The closest Earth equivalent to the doctrine of IDIC, emphasizing the permutations and combinations of reality to reveal the surreal, is kabbalah, although both Christian Scholasticism and Taoism share some IDIC-like features.
