INTRODUCTION.
In every human society, there is an effort continually tending to confer on one part the height of power and happiness, and to reduce the other to the extreme of weakness and misery. The intent of good laws is to oppose this effort, and to diffuse their influence universally and equally. But men generally abandon the care of their most important concerns to the uncertain prudence and discretion of those, whose interest it is to reject the best and wisest institutions; and it is not till they have been led into a thousand mistakes, in matters the most essential to their lives and liberties, and are weary of suffering, that they can be induced to apply a remedy to the evils with which they are oppressed. It is then they begin to conceive, and acknowledge the most palpable truths, which, from their very simplicity, commonly escape vulgar minds, incapable of analysing objects, accustomed to receive impressions without distinction, and to be determined rather by the opinions of others, than by the result of their own examination.
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 proceeding in criminal cases, so principal a part of the legislation, and so much neglected throughout Europe, has hardly ever been called in question. Errors, accumulated through many centuries, have never 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 authorized 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.
