A few words about the origin of the graphic symbols. We have represented black sensing with the symbol :Se: — a figure that suggest the fullest contact with the external world. Intuition is a triangle :Ne:, which fits perfectly into a circle. Logic and ethics are the external form and the internal content of the same process. Therefore, if we represent logic with a square :Te: — a symbol of strict reasoning — then a symbol that fits into a square must be chosen to represent the internal aspect of the same process. Thus was born a square without one corner — :Fe:.
We will assign corresponding field elements the same symbols, only with a different color: :Si:, :Ni:, :Ti:, and :Fi:.
