Our reason could motivate us to extend our empathy, could motivate us to write a book like "Uncle Tom's Cabin," or read a book like "Uncle Tom's Cabin," and our reason can motivate us to create customs and taboos and laws that will constrain us from acting upon our impulses when, as rational beings, we feel we should be constrained.
A nossa razão pode motivar-nos a alargar a nossa empatia, pode levar-nos a escrever  "A Cabana do Pai Tomás", ou a ler "A Cabana do Pai Tomás". E a nossa razão pode motivar-nos a criar costumes e "tabus" e leis que nos impedem de agir de acordo com os nossos impulsos quando, enquanto seres racionais, sentimos que devemos ser restringidos.
