Reason, after all, has sup-posedly reigned supreme since the Age of Enlightenment back in the 17th century. Yet even the most casual observer of history can bear witness to our species' sad legacy of attempts at pure reason. When we try by means of reason alone to divine the workings of the universe or to conduct relationships with one another, we falter. Linearity, logic, and clarity of thought unquestionably play a significant role in the unfolding of nature's secrets. Call it intuition.
Intuition exists outside the stream of ordinary consciousness.
It may arrive as a mathematical equation, as an invention, or as a decision about the best path to take. Two such technologies are the ancient Chinese oracle known as the I Ching and the Tarot.
