Simon, I think we imagine repeating similar experiences as having to exactly replicate them as we might in rituals where deviation in the smallest detail can disrupt the chain of causality (or displease the gods) leading to failure? Doing the same thing over and over again is a sign of madness, or a sign of learning what works, or a lazy shortcut, or a sign of expertise, or who knows what? Often we know what we want so well we see it caused by everything we do. Reading about difference right now and I don’t think it is understood for the beauty of its representing something unresolved.
