According to Locke, in the hypotheticalstate of nature” that precedes the creation of human societies, men live “equal one amongst another without subordination or subjection,” and they are perfectly free to act and to dispose of their possessions as they see fit, within the bounds of natural law. From these and other premises Locke draws the conclusion that political society—i.e., government—insofar as it is legitimate, represents a social contract among those who have “consented to make one Community or Government…wherein the Majority have a right to act and conclude the rest.” These two ideas—the consent of the governed and majority rule—became central to all subsequent theories of democracy. For Locke they are inextricably connected: “For if the consent of the majority shall not in reason, be received, as the act of the whole, and conclude every individual; nothing but the consent of every individual can make anything be the act of the whole: But such a consent is next to impossible ever to be had.” Thus no government is legitimate unless it enjoys the consent of the governed, and that consent cannot be rendered except through majority rule.

Given these conclusions, it is somewhat surprising that Locke’s description of the different forms of government (he calls them “commonwealths”) does not explicitly prescribe democracy as the only legitimate system. Writing in England in the 1680s, a generation after the Commonwealth ended with the restoration of the monarchy (1660), Locke was more circumspect than this. Nevertheless, a careful reading of the relevant passages of the Second Treatise shows that Locke remains true to his fundamental principle, that the only legitimate form of government is that based on the consent of the governed.

Locke differentiates the various forms of government on the basis of where the people choose to place the power to make laws. His categories are the traditional ones: If the people retain the legislative power for themselves, together with the power to appoint those who execute the laws, then “the Form of the Government is a perfect Democracy.” If they put the power “into the hands of a few select Men, and their Heirs or Successors,…then it is an Oligarchy: Or else into the hands of one Man, and then it is a Monarchy.” Nevertheless, his analysis is far more subversive of nondemocratic forms of government than it appears to be. For whatever the form of government, the ultimate source of sovereign power is the people, and all legitimate government must rest on their consent. Therefore, if a government abuses its trust and violates the people’s fundamental rights—particularly the right to property—the people are entitled to rebel and replace that government with another to whose laws they can willingly give their consent. And who is to judge whether the government has abused its trust? Again, Locke is unequivocal: the people themselves are to make that judgment. Although he does not use the term, Locke thus unambiguously affirms the right of revolution against a despotic government.

Less than a century later, Locke’s views were echoed in the famous words of the United States Declaration of Independence:

We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty, and the pursuit of Happiness. That to secure these rights, Governments are instituted among Men, deriving their just powers from the consent of the governed, that whenever any Form of Government becomes destructive of these ends, it is the Right of the People to alter or abolish it, and to institute new government, laying its foundation on such principles and organizing its powers in such form, as to them shall seem most likely to effect their Safety and Happiness.

Answers to fundamental questions

Although Locke’s ideas were radical—even quietly revolutionary—in his time, his answers to questions 1 through 3 would need further elaboration, and even some alteration, as the theory and practice of democracy continued to develop.

Regarding question 1—What is the appropriate association within which a democratic government should be established?—despite the generality of his conclusions, Locke clearly intended them to apply to England as a whole, and presumably also to other nation-states. Departing from views that still prevailed among political philosophers of his time, Locke held—as the Levelers did—that democracy did not require a small political unit, such as a city-state, in which all members of the dēmos could participate in government directly. Here again, Locke was at the forefront of the development of democratic ideas.

Regarding question 2—Who should constitute the dēmos?—Locke believed, along with almost everyone else who had expressed an opinion on the issue, that children should not enjoy the full rights of citizenship, though he maintained that parents are morally obliged to respect their children’s rights as human beings. With almost no substantive argument, Locke adopted the traditional view that women should be excluded from the dēmos, though he insisted that they retain all other fundamental rights. More than a century would pass before “the consent of the people” was generally understood to include the consent of women.

Unlike the men of Athens or the small male aristocracy of Venice, obviously the men of England could not govern directly in an assembly. In this case, then, the answer to question 3—What political institutions are necessary for governing?—would have to include the use of representatives chosen by the people. Yet, though it seems clear that Locke’s government by consent requires representation, he provided little guidance as to the form it might take. This is perhaps because he, like his contemporary readers, assumed that democracy and majority rule would be best implemented in England through parliamentary elections based on an adult-male franchise.

Montesquieu

The French political theorist Montesquieu, through his masterpiece The Spirit of the Laws (1748), strongly influenced his younger contemporary Rousseau (see below Rousseau) and many of the American Founding Fathers, including John Adams, Jefferson, and Madison. Rejecting Aristotle’s classification, Montesquieu distinguishes three ideal types of government: monarchy, “in which a single person governs by fixed and established laws”; despotism, “in which a single person directs everything by his own will and caprice”; and republican (or popular) government, which may be of two types, depending on whether “the body, or only a part of the people, is possessed of the supreme power,” the former being a democracy, the latter an aristocracy.

According to Montesquieu, a necessary condition for the existence of a republican government, whether democratic or aristocratic, is that the people in whom supreme power is lodged possess the quality of “public virtue,” meaning that they are motivated by a desire to achieve the public good. Although public virtue may not be necessary in a monarchy and is certainly absent in despotic regimes, it must be present to some degree in aristocratic republics and to a large degree in democratic republics. Sounding a theme that would be loudly echoed in Madison’s “Federalist 10,” Montesquieu asserts that without strong public virtue, a democratic republic is likely to be destroyed by conflict between various “factions,” each pursuing its own narrow interests at the expense of the broader public good.

Hume

The destructive power of factions was also strongly emphasized by the Scottish philosopher and historian David Hume, whose influence on Madison was perhaps even greater than Montesquieu’s. For it was from Hume that Madison seems to have acquired a view about factions that turned the issue of the desirability of larger political associations—i.e., those larger than the city-state—on its head. For the purpose of diminishing the destructive potential of factionalism, so Hume and Madison argued, bigger is in fact better, because in bigger associations each representative must look after a greater diversity of interests. It is also likely that Madison was influenced by Hume when in “Federalist 10” he rejected the term democracy for the type of government based on representation, preferring instead to call it a republic.

Rousseau

When compared with Locke, Jean-Jacques Rousseau sometimes seems the more radical democrat, though a close reading of his work shows that, in important respects, Rousseau’s conception of democracy is narrower than Locke’s. Indeed, in his most influential work of political philosophy, The Social Contract (1762), Rousseau asserts that democracy is incompatible with representative institutions, a position that renders it all but irrelevant to nation-states (see state). The sovereignty of the people, he argues, can be neither alienated nor represented. “The idea of representatives is modern,” he wrote. “In the ancient republics…the people never had representatives.…[T]he moment a people allows itself to be represented, it is no longer free: it no longer exists.” But if representation is incompatible with democracy, and if direct democracy is the only legitimate form of government, then no nation-state of Rousseau’s time or any other can have a legitimate government. Furthermore, according to Rousseau, if a political association that is small enough to practice direct democracy, such as a city-state, were to come into existence, it would inevitably be subjugated by larger nation-states and thereby cease to be democratic.

For these and other reasons, Rousseau was pessimistic about the prospects of democracy. “It is against the natural order for the many to govern and the few to be governed,” he wrote. “It is unimaginable that the people should remain continually assembled to devote their time to public affairs.” Adopting a view common among critics of democracy in his time, Rousseau also held that “there is no government so subject to civil wars and intestine agitations as democratic or popular government.” In a much-cited passage, he declares that, “were there a people of gods, their government would be democratic. So perfect a government is not for men.”

Despite these negative conclusions, Rousseau hints, in a brief footnote (Book III, chapter 15), that democratic governments may be viable if joined together in confederations. Some years later, in a discussion of how the people of Poland might govern themselves, he allowed that there is simply no alternative to government by representation. However, he left the problem of the proper size or scale of democratic political associations largely unsolved.

Mill

In his work On Liberty (1859) John Stuart Mill argued on utilitarian grounds that individual liberty cannot be legitimately infringed—whether by government, society, or individuals—except in cases where the individual’s action would cause harm to others. In a celebrated formulation of this principle, Mill wrote that

the sole end for which mankind are warranted, individually or collectively, in interfering with the liberty of action of any of their number, is self-protection.…The only purpose for which power can be rightfully exercised over any member of a civilised community, against his will, is to prevent harm to others. His own good, either physical or moral, is not a sufficient warrant.

Mill’s principle provided a philosophical foundation for some of the basic freedoms essential to a functioning democracy, such as freedom of association (see below Ideal and representative democracy), and undermined the legitimacy of paternalistic laws, such as those requiring temperance, which in Mill’s view treated adult citizens like children. In the area of what he called the liberty of thought and discussion, another freedom crucial to democracy, Mill argued, also on utilitarian grounds, that legal restrictions on the expression of opinion are never justified. The “collision of adverse opinions,” he contended, is a necessary part of any society’s search for the truth. In another work, Considerations on Representative Government (1861), Mill set forth in a lucid and penetrating manner many of the essential features of the new type of government, which had not yet emerged in continental Europe and was still incomplete in important respects in the United States. In this work he also advanced a powerful argument on behalf of woman suffrage—a position that virtually all previous political philosophers (all of them male, of course) had ignored or rejected.

Dewey

According to the American philosopher John Dewey, democracy is the most desirable form of government because it alone provides the kinds of freedom necessary for individual self-development and growth—including the freedom to exchange ideas and opinions with others, the freedom to form associations with others to pursue common goals, and the freedom to determine and pursue one’s own conception of the good life. Democracy is more than merely a form of government, however; as Dewey remarks in Democracy and Education (1916), it is also a “mode of associated life” in which citizens cooperate with each other to solve their common problems through rational means (i.e., through critical inquiry and experiment) in a spirit of mutual respect and good will. Moreover, the political institutions of any democracy, according to Dewey, should not be viewed as the perfect and unchangeable creations of visionary statesmen of the past; rather, they should be constantly subject to criticism and improvement as historical circumstances and the public interest change.

Participation in a democracy as Dewey conceived it requires critical and inquisitive habits of mind, an inclination toward cooperation with others, and a feeling of public spiritedness and a desire to achieve the common good. Because these habits and inclinations must be inculcated from a young age, Dewey placed great emphasis on education; indeed, he called public schools “the church of democracy.” His contributions to both the theory and practice of education were enormously influential in the United States in the 20th century (see also education, philosophy of).

Dewey offered little in the way of concrete proposals regarding the form that democratic institutions should take. Nevertheless, in The Public and Its Problems (1927) and other works, he contended that individuals cannot develop to their fullest potential except in a social democracy, or a democratic welfare-state. Accordingly, he held that democracies should possess strong regulatory powers. He also insisted that among the most important features of a social democracy should be the right of workers to participate directly in the control of the firms in which they are employed.

Given Dewey’s interest in education, it is not surprising that he was greatly concerned with the question of how citizens might better understand public affairs. Although he was a proponent of the application of the social sciences to the development of public policy, he sharply criticized intellectuals, academics, and political leaders who viewed the general public as incompetent and who often argued for some form of democratic elitism. Only the public, he maintained, can decide what the public interest is. In order for citizens to be able to make informed and responsible decisions about their common problems, he thought, it is important for them to engage in dialogue with each other in their local communities. Dewey’s emphasis on dialogue as a critical practice in a democracy inspired later political theorists to explore the vital role of deliberation in democratic systems.

Habermas

In a series of works published after 1970, the German philosopher and social theorist Jürgen Habermas, employing concepts borrowed from Anglo-American philosophy of language, argued that the idea of achieving a “rational consensus” within a group on questions of either fact or value presupposes the existence of what he called an “ideal speech situation.” In such a situation, participants would be able to evaluate each other’s assertions solely on the basis of reason and evidence in an atmosphere completely free of any nonrational “coercive” influences, including both physical and psychological coercion. Furthermore, all participants would be motivated solely by the desire to obtain a rational consensus, and no time limits on the discussion would be imposed. Although difficult if not impossible to realize in practice, the ideal speech situation can be used as a model of free and open public discussion and a standard against which to evaluate the practices and institutions through which large political questions and issues of public policy are decided in actual democracies.

Rawls

From the time of Mill until about the mid-20th century, most philosophers who defended democratic principles did so largely on the basis of utilitarian considerations—i.e., they argued that systems of government that are democratic in character are more likely than other systems to produce a greater amount of happiness (or well-being) for a greater number of people. Such justifications, however, were traditionally vulnerable to the objection that they could be used to support intuitively less-desirable forms of government in which the greater happiness of the majority is achieved by unfairly neglecting the rights and interests of a minority.

In A Theory of Justice (1971), the American philosopher John Rawls attempted to develop a nonutilitarian justification of a democratic political order characterized by fairness, equality, and individual rights. Reviving the notion of a social contract, which had been dormant since the 18th century, he imagined a hypothetical situation in which a group of rational individuals are rendered ignorant of all social and economic facts about themselves—including facts about their race, sex, religion, education, intelligence, talents or skills, and even their conception of the “good life”—and then asked to decide what general principles should govern the political institutions under which they live. From behind this “veil of ignorance,” Rawls argues, such a group would unanimously reject utilitarian principles—such as “political institutions should aim to maximize the happiness of the greatest number”—because no member of the group could know whether he belonged to a minority whose rights and interests might be neglected under institutions justified on utilitarian grounds. Instead, reason and self-interest would lead the group to adopt principles such as the following: (1) everyone should have a maximum and equal degree of liberty, including all the liberties traditionally associated with democracy; (2) everyone should have an equal opportunity to seek offices and positions that offer greater rewards of wealth, power, status, or other social goods; and (3) the distribution of wealth in society should be such that those who are least well-off are better off than they would be under any other distribution, whether equal or unequal. (Rawls holds that, given certain assumptions about human motivation, some inequality in the distribution of wealth may be necessary to achieve higher levels of productivity. It is therefore possible to imagine unequal distributions of wealth in which those who are least well-off are better off than they would be under an equal distribution.) These principles amount to an egalitarian form of democratic liberalism. Rawls is accordingly regarded as the leading philosophical defender of the modern democratic capitalist welfare state.

Ideal democracy”

As noted above, Aristotle found it useful to classify actually existing governments in terms of three “ideal constitutions.” For essentially the same reasons, the notion of an “ideal democracy” also can be useful for identifying and understanding the democratic characteristics of actually existing governments, be they of city-states, nation-states, or larger associations.

It is important to note that the term ideal is ambiguous. In one sense, a system is ideal if it is considered apart from, or in the absence of, certain empirical conditions, which in actuality are always present to some degree. Ideal systems in this sense are used to identify what features of an actual system are essential to it, or what underlying laws are responsible, in combination with empirical factors, for a system’s behaviour in actual circumstances. In another sense, a system is ideal if it is “best” from a moral point of view. An ideal system in this sense is a goal toward which a person or society ought to strive (even if it is not perfectly attainable in practice) and a standard against which the moral worth of what has been achieved, or of what exists, can be measured.

These two senses are often confused. Systems that are ideal in the first sense may, but need not, be ideal in the second sense. Accordingly, a description of an ideal democracy, such as the one below, need not be intended to prescribe a particular political system. Indeed, influential conceptions of ideal democracy have been offered by democracy’s enemies as well as by its friends.
