If we would bring to the study of Beccaria’s treatise the same disposition of mind with which he wrote it, we must enter upon the subject with the freest possible spirit of inquiry, and with a spirit of doubtfulness, undeterred in its research by authority however venerable, by custom however extended, or by time however long. It has been from too great reverence for the wisdom of antiquity that men in all ages have consigned their lives and properties to the limited learning and slight experience of generations which only lived for themselves and had no thought of binding posterity in the rules they thought suitable to their own times. Beccaria sounded the first note of that appeal from custom to reason in the dominion of law which has been, perhaps, the brightest feature in the history of modern times, and is still transforming the institutions of all countries.
