If we look into history we shall find that laws, which are, or ought to be, conventions between men in a state of freedom. have been, for the most part the work of the passions of a few, or the consequences of a fortuitous or temporary necessity; not dictated by a cool examiner of human nature, who knew how to collect in one point the actions of a multitude, and had this only end in view, the greatest happiness of the greatest number. Happy are those few nations who have not waited till the slow succession of human vicissitudes should, from the extremity of evil, produce a transition to good; but by prudent laws have facilitated the progress from one to the other! And how great are the obligations due from mankind to that philosopher, who, from the obscurity of his closet, had the courage to scatter among the multitude the seeds of useful truths, so long unfruitful!
The art of printing has diffused the knowledge of those philosophical truths, by which the relations between sovereigns and their subjects, and between nations are discovered. By this knowledge commerce is animated, and there has sprung up a spirit of emulation and industry, worthy of rational beings. These are the produce of this enlightened age; but the cruelty of punishments, and the irregularity of proceedings in criminal cases, so principal a part of the legislation, and so much neglected throughout Europe, has hardly ever been called in question. Efforts, accumulated through many centuries, have never yet been exposed by ascending to general principles; nor has the force of acknowledged truths been ever opposed to the unbounded licentiousness of ill-directed power, which has continually produced so many authorised examples of the most unfeeling barbarity. Surely, the groans of the weak, sacrificed to the cruel ignorance and indolence of the powerful, the barbarous torments lavished, and multiplied with useless severity, for crimes either not proved, or in their nature impossible, the filth and horrors of a prison, increased by the most cruel tormentor of the miserable, uncertainty, ought to have roused the attention of those whose business is to direct the opinions of mankind.
The immortal Montesquieu has but slightly touched on this subject. Truth, which is eternally the same, has obliged me to follow the steps of that great man; but the studious part of mankind, for whom I write, will easily distinguish the superstructure from the foundation. I shall be happy if, with him, I can obtain the secret thanks of the obscure and peaceful disciples of reason and philosophy, and excite that tender emotion in which sensible minds sympathise with him who pleads the cause of humanity.
