the person himself—not his body or his name, the physical universe, his mind, or anything else; that which is aware of being aware; the identity which is the individual. The term was coined to eliminate any possible confusion with older, invalid concepts. It comes from the Greek letter theta (0?-), which the Greeks used to represent thought or perhaps spirit, to which an n is added to make a noun in the modern style used to create words in engineering. It is also 0?-n, or "theta to ?the nth degree," meaning unlimited or vast. —FutureOrg Trends Approved 4.3.91
