I bought myself a Citizen Eco-Drive watch. It’s great, I’m really happy with it; it looks good, it’s waterproof; but I bought it because it will never need a battery replacement or a wind-up. It’s powered very successfully, by the sun or artificial light – that was important because I live in Seattle.
Descartes: “Cognito ergo sum,” – “I think therefore I am,” the great maxim of the rationalists; which has been adequately answered by Kierkegaard’s Existentialism and Husserl’s Phenomenology: “I am, therefore I am“.
Which is disturbingly equal to something Moses wrote about 4000 years ago! Now Existentialism may have answered Rationalism adequately, but it is yet to answer itself adequately.
Newton’s famous third law of motion, the law of reciprocal actions, states that for every action there is an equal and opposite reaction. This is true in physics, and physics, as we have always known, is all about relationships. But it is also true in personal relationships, and the more intimate the relationship, the more profound the action and reaction.
