Pain. 1979 Jun;6(3):253-264. doi: 10.1016/0304-3959(79)90047-2.
Pain is better classified as an awareness of a need-state than as a sensation. It serves more to promote healing than to avoid injury. It has more in common with the phenomena of hunger and thirst than it has with seeing or hearing. The period after injury is divided into the immediate, acute and chronic stages. In each stage it is shown that pain has only a weak connection to injury but a strong connection to the body state.
疼痛更应被归类为对需求状态的一种感知，而非一种感觉。它更多地是促进愈合，而非避免受伤。它与饥饿和口渴现象的共同点，比与视觉或听觉的共同点更多。损伤后的时期分为即刻期、急性期和慢性期。在每个阶段都表明，疼痛与损伤的关联较弱，但与身体状态的关联较强。
