Classical Liberalism

The Enlightenment doctrine that legitimate government rests on consent, is limited to protecting life, liberty and property, and is bound by law it cannot itself override.

Key thinkers

• John Locke
• Adam Smith
• John Stuart Mill

Origins

Emerged from the English constitutional conflicts of the seventeenth century, given systematic form by John Locke in 1689, extended into economics by Adam Smith in 1776 and into the philosophy of liberty by John Stuart Mill in 1859.

The three claims

Classical liberalism rests on a small number of connected propositions. Political authority is artificial rather than natural, constructed by those subject to it. It exists for a limited purpose, the protection of persons and their holdings. And it is bound by general, prospective rules that apply to rulers as well as to the ruled — the principle later called the rule of law, as distinct from rule by law.

Each claim was radical when made. Together they denied the divine right of kings, established a criterion by which any government could be judged deficient, and supplied the intellectual basis for the American and French revolutions.

Smith and the market argument

Adam Smith's contribution in The Wealth of Nations (1776) is routinely reduced to a defence of self-interest, which misreads him badly. Smith's central analytical insight concerns the division of labour and the extent of the market; his argument for competition is that it disciplines producers, and his sharpest criticism throughout the book is directed at merchants who use political influence to escape that discipline.

Smith supported public education, infrastructure funded by general taxation, progressive elements in taxation, and regulation of banking. Read alongside The Theory of Moral Sentiments (1759), which grounds social life in sympathy rather than calculation, he is a considerably more qualified figure than either his admirers or his critics usually allow.

Mill and the harm principle

John Stuart Mill's On Liberty (1859) supplied the tradition's clearest statement of the limits of legitimate interference: power may be exercised over a person against their will only to prevent harm to others. Mill was as concerned with social conformity as with state coercion, arguing that the tyranny of prevailing opinion can penetrate more deeply into private life than any law.

Mill also marks the point at which the tradition begins to divide. His later economic writing moved toward cooperative ownership and substantial redistribution, opening the path to the social liberalism of the twentieth century — while other heirs held to the earlier emphasis on non-interference. Both descend from Mill, which is why classical liberalism cannot be assigned to a single point on a compass.

What it did and did not deliver

The tradition's achievements are substantial and easy to take for granted: constitutional government, religious toleration, freedom of the press, due process, the abolition of legal privilege by birth, and the legal framework within which the largest expansion of material welfare in human history took place.

Its historical limitations are equally clear. Its universal language coexisted with property qualifications for the franchise, the exclusion of women from civic life, and colonial rule. Whether these were contradictions of the doctrine or applications of it remains genuinely disputed — but the pressure that eventually removed them came largely from people holding classical liberalism to its own premises.

Core tenets

• Government by consent, with authority derived from the governed.
• Rights to life, liberty and property that precede and constrain government.
• The rule of law: general prospective rules binding on rulers.
• Freedom of conscience, expression and association.
• Free exchange and competitive markets, with a limited state.

Common criticisms

• Formal liberty without material means may amount to very little in practice, a criticism Mill himself came to accept.
• The doctrine developed alongside slavery and empire, and its universalism was applied selectively for two centuries.
• Treating property rights as pre-political ignores that they are defined and enforced by law.
• Its individualist starting point underweights the communities and relationships that actually form people.
• Concentrated private power can coerce as effectively as the state, which the classical framework addresses poorly.
