"The dog wags its tail only at living things. A tail wag, the equivalent of a human smile, is bestowed upon people, dogs , cats, squirrels, even mice and butterflies. - but no lifeless things. A dog won't wag its tail to its dinner or to a bed, card, stick, or even a bone."

They [rulers] must act like a good physician who, when gangrene has set in proceeds without mercy to cut, saw, and burn flesh, veins, bone, and marrow. Such a procedure must also be followed in this instance. Burn down their synagogues, forbid all that I enumerated earlier, force them to work, and deal harshly with them, as Moses did... If this does not help we must drive them out like mad dogs.
