I remember passing a window in London in which a sewing-machine was displayed. The machine was working. A large doll sat beside it, its hand on the wheel. The doll's hand appeared to be turning the handle. As a matter of fact, the machine was electrically driven, and the wheel turned the hand of the doll.In the realm of cause and effect we are frequently the dupes and victims of a very dexterous system of legerdemain. The resultant quantity is invariably clear; the contributing causes are not what they seem.
I find myself believing today pretty much what I believed twenty years ago; but I find myself believing the same things for different reasons. As life goes on, a man learns to put more and more confidence in his conclusions, and to become more and more chary of the reasons that led to those conclusions. If a certain course seems to him to be right, he automatically adopts it, and he confidently persists in it even after the reasons that first dictated it have fallen under suspicion.
‘More than once in an emergency at sea,’ says Dr. Grenfell, the hero of Labrador, ‘I have swiftly decided upon a certain line of action. If I had waited to hem my reason into a corner before adopting that course, I should not be here to tell the tale.’
We often flatter ourselves that we base our conclusions upon our reasons. In reality, we do nothing of the kind. The mind works so rapidly that it tricks us. It is another case of legerdemain. Once more, it is the machine that turns the doll, and not the doll that turns the machine.
