Aesop,
Æsop's Fables, Embellished with One Hundred and Eleven Emblematical Devices
“ Why should we think others born to hard treatment more than ourselves? Or imagine it can be reasonable to do to another, what we ourselves should be unwilling to suffer? In our behaviour to all mankind, we need only ask ourselves these plain questions, and our consciences will tell us how to act. Conscience, like a good valuable domestic, plays the remembrancer to us upon all occasions, and gives us a gentle twitch, when we are going to do a wrong thing. It does not, like the adder in the fable, bite us to death, but only gives us kind cautions. ”
