“At first—long before indeed—he had been much occupied with one question; why almost all crimes are so badly concealed and so easily detected, and why almost all criminals leave such obvious traces? He had come gradually to many different and curious conclusions, and in his opinion the chief reason lay not so much in the material impossibility of concealing the crime, as in the criminal himself. Almost every criminal is subject to a failure of will and reasoning power by a childish and phenomenal heedlessness, at the very instant when prudence and caution are most essential. It was his conviction that this eclipse of reason and failure of will power attacked a man like a disease, developed gradually and reached its highest point just before the perpetration of the crime, continued with equal violence at the moment of the crime and for longer or shorter time after, according to the individual case, and then passed off like any other disease. The question whether the disease gives rise to the crime, or whether the crime from its own peculiar nature is always accompanied by something of the nature of disease, he did not yet feel able to decide.”

“The only power any government has is the power to crack down on criminals. Well, when there aren’t enough criminals, one makes them. One declares so many things to be a crime that it becomes impossible for men to live without breaking laws.”

“Remember particularly that you cannot be a judge of anyone. For no one can judge a criminal until he recognizes that he is just such a criminal as the man standing before him, and that ha perhaps is more than all men to blame for that crime. When he understands that, he will be able to judge...If you can take upon yourself the crime of the criminal your heart is judging, take it at once, suffer for him yourself, and let him go without reproach.”

“I need not pause to explain that crime is not a disease. It is criminology that is a disease.”

“There's no way to rule innocent men. The only power any government has is the power to crack down on criminals. Well, when there aren't enough criminals, one makes them. One declares so many things to be a crime that it becomes impossible for men to live without breaking laws.”

“In existing criminology there are concepts: a criminal man, a criminal profession, a criminal society, a criminal sect, and a criminal tribe; but there is no concept of a criminal state, or a criminal government, or criminal legislation. Consequently, the biggest crimes actually escape being called crimes.”
