‘For, in simple and permitted matters, our natural appetites warn us not to exceed the boundaries of what is permissible for us. The tiger, which spills blood in the natural course of things, because this is its state of being, its destiny, needs only for its sense of smell to inform it that a prey is within reach; immediately it leaps towards this prey, falls on it and tears it apart. That is its instinct, which it obeys. But mankind, on the contrary, is repelled by blood. It is not the laws of society that condemn murder, but the laws of nature.’
