" If the foot had never realized it belonged to the body, & that there never was a body on which it depended, if it had only known & loved itself & then came to know that it really belonged to the body on which it depended, think of the regret & shame it would feel for its past existence. It would recognize how useless it had been to the body in spite of the life poured into it, & how it would have been destroyed if the body had rejected it & cut it off as the foot cut itself off from the body! How it would have desired earnestly to be kept on! How obediently it would let itself be governed by the will in charge of the body, to the point of being amputated if necessary! Otherwise it would cease to a member, for every member must be ready to perish for the sake of the whole, for whose sake alone exists. "

― Blaise Pascal , The Mind on Fire: A Faith for the Skeptical and Indifferent
