I think there is something wonderful in the concept of inverses. Inverses are not opposites. Inverses are regularly needed in mathematical formulas. Lets take it to the world of philosophy. HallsofIvy...for example is my inverse. He/She is 2 over 1. I am 1 over 2. 2 is analytical genius. 1/2 is philosophical genius. We desperately need each other. Mathematicians need philosophers. Philosophers need mathematicians. Without inverses, many formulas in mathematics would not work. Let us work together. Let us remerge philosophy and mathematics!
