Virtual Virtual has a wide range of meanings. Some merely see it as the opposite of Reality, whereby Virtual Raelity would be opposed to Relaity. Some go further. Hence Counterfactual History is also called Virtual History as if to emphasize its oppostion even to truth. This overlooks the history of Virtual Reaity, e.g. Evans, Sutherland who were both concerned with military applicaitons and Krueger who was fascinated by artistic, creative implications.

The word virtus is linked with the Latin word for man: vir which also means power and strength and is based on the Sanskrit vira and vIra which goes back to at elast 2000 B.C. The word Virtuality also occurs in the Celtic tradition among the three cauldrons of: Virtuality, Acquisition, Wisdom whioch again have their parallels in the Sanskrit triad of Potentiality, Agency, Actuality that is linked with the ever recurring: sattva, rajas and tamas. which generates a whole series of trads, triple or trinities including: Essence, Activty, Inertia Goodness, Passion, Darkness Jing, Qi, Shen Light, Energy, Inertia Potentiality, Agency, Actuality Shin, Resh,Tav Spirit, Force, Matter Vairocana, Lotus, Vajra Virtue , Foulness, Ignorance Virtue, Motion/Passion, Lethargy Wisdom, Power, Compassion the limitless One, the delimiting Divisor, the limited Several and more familiar versions such as: Thought, Speech, Action Thought, Word, Deed.
