It’s a strange thing that something utterly immediate at the time can fade into nothingness so quickly. A couple months ago I shattered my knuckle, resulting in unbearable pain. But oddly enough, when I look back on it now, the experience is so painless, so sanitised, that I wonder why I made such a fuss. Not only that, I actually begin to think that it may have been a good experience, somehow character-building. I can remember it happened, I can remember I never wanted it to happen again and I gritted my teeth, but I can’t actually feel it.
It’s like the memory of a smell. I can remember roses smell good, I could even recognise the smell. But I just can’t smell it in my memory. With sight and sound it’s different. If you were asked to conjure up an image of your house, you could probably do it. Not just remember that your house is blue, that it looks ugly, that you prefer red houses, but actually remember the image of the house, and be able to see it again when you close your eyes. Now try and close your eyes and remember what pain feels like.
Of course, when I say you can conjure up the memory of your house, you can do it, but only up to a point. Even if you think you can see it in your mind, I could ask you the colour of the flowers in the window and you probably won’t know. That's because your memory doesn’t really have an image imprinted on it like a computer. Memory just takes the best parts, the one’s you’re most interested in, and forgets the rest. Nonetheless, you still can make an image, however vague, in your mind. But you can’t recreate pure physical pain. Pain isn’t even something with lots of details to remember, like a song, or a picture. Pain is just a pure emotion, in fact even less than an emotion, just a pure physical state. It’s like not being able to recall the colour red, in fact even more elemental than that.
So what about Pavlov and his dogs or Skinner and his rats? It’s been proved that you can condition an animal by punishing it with physical pain. Could it be that only humans forget the actuality of pain, that other animals have no such difficulties in remembering it? More likely, I think, that other animals, no matter how simple can learn and remember that pain is not something they wish to happen to them again.
Perhaps I’m looking at this too much from the perspective of a middleclass English white boy. After all, a beaten dog may wince even at the sight of the whip. However, even then I think that what is remembered is the emotional anguished caused by the physical pain, and not the pain itself. Under the influence of pain, at the extremes, one can be persuaded to anything (after all, think of room 101 in 1984, or if you prefer non-fiction, of the countless false confessions by torture throughout history). There is no denying the power of imprinting in such a state, but I think that it makes the lack of recall even more odd.
On the other hand, it would be bizarre if we could in fact recall pain. Unlike other memories, like a voice, pain is not limited in time to a specific event or even series of events, but is constant in life, always ready to be awakened. Being able to recall pain would be like being able to recall what it feels like to be asleep. Imagine the absurdity of people yelping in pain or falling asleep while re-living their memories! And if you could turn pain on in order to remember it, then you would have to be able to turn it off just as easily, something the human body could never allow because it knows the inherent weakness of the human mind.
If it were not for our ability to forget our pain, so much of the violence, perseverance, sacrifices and striving of humanity might never have come to pass.
