ただし，understand と pain は，一度しか用いてはならない。
It is not possible to understand other people's pain.
Of course it's impossible to truly understand another's pain, because we cannot experience anything in the exact same way another person would. But that doesn't mean we cannot see when someone hurts and commiserate. Humans are empathetic creatures. We are able to detect others' feelings, and often we mirror them. Seeing others hurt, especially those we love, causes us anguish. (60)
Watching a person receive a beating or hearing the shriek of a distressed child causes an unpleasant emotional reaction in most psychologically healthy people. I argue that this reaction is evidence that we can understand others' sensations to at least some degree through visual and linguistic cues. To say it is impossible to comprehend another's pain is therefore an overstatement. (60)

・"It is not possible"という絶対的な言い方に注目。相手のpainを十分理解できる例外をひとつ挙げれば、disagreeの立場を支えられるかもしれません。
