Perhaps that view is, to some extent, influenced by a reluctance to offer excuses for what I did or to hide behind mitigation of my own convenient construction, rather than face up to the fact that to have derived so much enjoyment from what I did, and to have disguised that enjoyment as having simply been doing my duty, is at best morally questionable.
During my time there I never believed in corporal punishment in the sense of it being of any real educational value. And in later years, after leaving the profession, it was that fact that often made me feel somewhat ashamed. At least many of those colleagues known for their over-frequent use of the cane and/or slipper actually believed, rightly or wrongly, in what they were doing. But I was doing it purely for myself. Given my views, if I had not enjoyed administering those slipperings, I would never have used CP even once in all the years I taught at that school.
