On problem-solving at the dance hall. The three sisters of modern thought and problem-solving are Deduction, Induction, and Abduction. All recognize each is beautiful, very rich, but quite proper. However, each is most different from the other. They arrive at the ballroom, ready to dance. No time at all passes before partners line up for their favors. Deduction is a bit stilted on the dance floor but knows every step that follows the previous. You will end up complete and correct. When the band stops, she will whisper QED in your ear. Induction needs much practice and many steps, but then finally knows the next step, and therefore full dance correctly and with rhythm. She can also dance backward. She could really dance all night. Abduction, if so inclined, will leap into your arms and teach you a few new dance steps you never dreamed of. You may not finish the dance, but you will know how to get there. When the music stops, she will disappear, almost as if floating away
