Why "Blackstone in America"?
Sir William Blackstone was an 18th-century English legal scholar who wrote a four-volume treatise on English law -- known among lawyers simply as "Blackstone" -- that was authoritative for many generations. His writings were, for example, highly influential on the Founders.
Among other things, Blackstone asserted concisely and straightforwardly the value of individual liberty under a constitutional government. For example:
THE absolute rights of man, considered as a free agent, endowed with discernment to know good from evil, and with power of choosing those measures which appear to him to be most desirable, are usually summed up in one general appellation, and denominated the natural liberty of mankind. This natural liberty consists properly in a power of acting as one thinks fit, without any restraint or control, unless by the law of nature: being a right inherent in us by birth, and one of the gifts of God to man at his creation, when he endued him with the faculty of freewill. But every man, when he enters into society, gives up a part of his natural liberty, as the price of so valuable a purchase; and, in consideration of receiving the advantages of mutual commerce, obliges himself to conform to those laws, which the community has thought proper to establish. And this species of legal obedience and conformity is infinitely more desirable, than that wild and savage liberty which is sacrificed to obtain it. For no man, that considers a moment, would wish to retain the absolute and uncontrolled power of doing whatever he pleases; the consequence of which is, that every other man would also have the same power; and then there would be no security to individuals in any of the enjoyments of life. Political therefore, or civil, liberty, which is that of a member of society, is no other than natural liberty so far restrained by human laws (and no farther) as is necessary and expedient for the general advantage of the publick. Hence we may collect that the law, which restrains a man from doing mischief to his fellow citizens, though it diminishes the natural, increases the civil liberty of mankind: but every wanton and causeless restraint of the will of the subject, whether practiced by a monarch, a nobility, or a popular assembly, is a degree of tyranny. Nay, that even laws themselves, whether made with or without our consent, if they regulate and constrain our conduct in matters of mere indifference, without any good end in view, are laws destructive of liberty: whereas if any public advantage can arise from observing such precepts, the control of our private inclinations, in one or two particular points, will conduce to preserve our general freedom in others of more importance; by supporting that state, of society, which alone can secure our independence. . . . So that laws, when prudently framed, are by no means subversive but rather introductive of liberty; for (as Mr Locke has well observed) where there is no law, there is no freedom. But then, on the other hand, that constitution or frame of government, that system of laws, is alone calculated to maintain civil liberty, which leaves the subject entire master of his own conduct, except in those points wherein the public good requires some direction or restraint.
THE idea and practice of this political or civil liberty flourish in their highest vigour in these kingdoms, where it falls little short of perfection, and can only be lost or destroyed by the folly or demerits of its owner: the legislature, and of course the laws of England, being peculiarly adapted to the preservation of this inestimable blessing even in the meanest subject. Very different from the modern constitutions of other states, on the continent of Europe, and from the genius of the imperial law; which in general are calculated to vest an arbitrary and despotic power of controlling the actions of the subject in the prince, or in a few grandees. And this spirit of liberty is so deeply implanted in our constitution, and rooted even in our very soil, that a slave or a negro, the moment he lands in England, falls under the protection of the laws, and with regard to all natural rights becomes eo instanti a freeman.
