Early Greek philosophers developed the ancient science of techne to explain personal inner powers or other metaphysical forces. Since this science was so profound and considered so magical, no doubt the early Catholic Church suppressed it along with everything associated with the Arian Heresy or pagan powers.
The word techne means “skill, art, cunning or a method of making or doing something.” Techne is a form of the root tek– as used in words such as used in tekmerion meaning “proof” or tekon meaning “giving birth.” These related words also help to define techne.
Ancient philosophers wanted to know how things come into being. Thus, they used the word techne to explain the source of power existing between cause and effect, In other words, techne explains how a hidden cause becomes its manifested effect. In short, techne was an ancient science of personal power to find creative solutions to problems independent of the normal methods of learning.
