“Since the great foundation of fear is pain, the way to harden and fortify children against fear and danger is to accustom them to suffer pain.”

“Inuring children gently to suffer some degrees of pain without shrinking, is a way to gain firmness to their minds, and lay a foundation for courage and resolution in the future part of their lives.”

“Arguments to the effect that it is wrong to cause pain and suffering to animals are often rejected by claiming that animals simply do not suffer. … Ironically, it is precisely upon the assumption that animals do suffer from stress, fear, and pain in a manner similar to humans that the validity of much of animal experimentation rests. Few, if any, conditions are studied as widely in animals as are pain, stress, ulcers, fear, and anxiety.”

“But the wise man is fortified against all inroads; he is alert; he will not retreat before the attack of poverty, or of sorrow, or of disgrace, or of pain. He will walk undaunted both against them and among them.”

“Pain is a gift. Humanity, without pain, would know neither fear nor pity. Without fear, there could be no humility, and every man would be a monster. The recognition of pain and fear in others give rise in us to pity, and in our pity is our humanity, our redemption.”

“Fear is pain arising from the anticipation of evil.”

“I don't think any drug that can cause brain damage, failing kidneys, hardening arteries, pain, and suffering should be made available. Drugs are not the way to the light. They won't lead to a fairy-tale life, they lead to suffering.”

“People fear death even more than pain. It's strange that they fear death. Life hurts a lot more than death. At the point of death, the pain is over. Yeah, I guess it is a friend”
