Pain (n.) can ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠be acute and durable together, while no pleasure is both very intense and very durable — so the two cannot even be weighed in one balance.

Pain (n.) may ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠be rarer than pleasure, but it is infinitely more violent and durable: one hour of it can outweigh a month of our common insipid enjoyments.

Pain (n.) of ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠a gentle kind following a violent one seems as nothing or even becomes a pleasure; a violent pain after a gentle one is doubly grievous.

Pain (n.) is ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠not proportioned to the disorder: a toothache convulses more than consumption — and vice is not punished by nature in exact measure either.

Pain (n.) seems ⁠​‌​​​‌​​​‌​‌‌​​​​‌​‌​​‌‌​‌​​‌​​​​​‌‌​​‌​​​‌‌​‌‌​⁠unnecessary: creatures could be moved by a mere diminution of pleasure; if an animal can be free of pain for an hour, it could be free of it forever.
