But that is another chapter in the philosophy of blindness. Let's turn away from cane travel for a moment and consider swimming. To a non-swimmer or even an impartial observer who is standing on the ground, the idea of swimming is foolish. We don't have air sacs along our spines like fish. Our only air sacs expand and contract with every breath.

It will not support you, and you will soon drown. I can go all the places I want to go my own way. The only way to learn to swim is to actually get into the water. Yes, at first you do thrash around, and sink, and come up coughing with your eyes and nose full of water. It takes a while to learn how to relax the right way to let the water support you.
