"I doubt that 'trying and failing' will do the trick. After all, many times we try to do something, fail at it, and yet - for whatever reasons - do not conclude "I can't do it." (It happened to me recently. I was trying to install a new pump on a dishwasher and was having no success, indeed I was failing miserably. I stopped for a while, tried again, and succeeded.) I am absolutely convinced that there is no phenomenological, introspective, felt (call it what you will) difference whatsoever between failing to do something which is possible (e.g. installing a dishwasher pump) and failing to do something which necessitarians call 'nomically impossible', e.g. flapping my arms and flying.
What do I feel when I find that I repeatedly fail to do something? Disappointment, remorse, anger, sadness, annoyance, irritability, fury, etc. Do I experience (physical or nomological) impossibility? Not that I can tell. I would not know how to recognize it if I did. I can experience that I have not done what I wanted; that I have tried especially hard; etc. But I do not see that I have experienced that I cannot do it. I may say, "I can't do it." But I have not experienced anything more than failure." -Norman Swartz
What evidence do you have that we experience something more than failure?
