I’ve always preferred holding a guitar plectrum with my middle finger and thumb instead of the usual index and thumb. I always felt guilty about it since I’ve noticed professionals seem to always use the index finger.
On two occasions I have been asked, 'Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?' I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.
