Cesare Beccaria

"No man can be judged a criminal until he be found guilty; nor can society take from him the public protection, until it have been proved that he has violated the conditions on which it was granted. What right, then, but that of power, can authorise the punishment of a citizen, so long as there remains any doubt of his guilt? The dilemma is frequent. Either he is guilty, or not guilty. If guilty, he should only suffer the punishment ordained by the laws, and torture becomes useless, as his confession is unnecessary. If he be not guilty, you torture the innocent; for, in the eye of the law, every man is innocent, whose crime has not been proved."

"[On the death penalty] Seems so absurd to me that the laws, that are the expression of the public will, that hate and punish the murder, make one themselves, and, to dissuade citizens from the murder, order a public murder. (Chapter XXVIII)"

"As punishments become more cruel, the minds of men, which like fluids always adjust to the level of their surroundings, become hardened, and the ever lively power of the emotions brings it about that after a hundred years of cruel tortures, the wheel causes no more fear than prison previously did. For a punishment to serve its purpose, it is only necessary that the harm that it inflicts outweighs the benefit that “the criminal can derive from the crime, and into the calculation of this balance, we must add the certainty of punishment and the loss of the good produced by the crime. Anything more than this is superfluous, and therefore tyrannical."

"Von keinem Nutzen ist die Todesstrafe, da sie den Menschen ein Grausamkeitsbeispiel gibt."

"Jede Strafe, die nicht von der absoluten Notwendigkeit diktiert wird, sagt der große Montesquieu, ist tyrannisch, ein Satz, der so verallgemeinert werden kann: Jeder Akt von zwischenmenschlicher Autorität, der nicht durch absolute Notwendigkeit begründet ist, ist tyrannisch."
