Criticism of democracy has been a key part of democracy and its functions. As Josiah Ober explains, "the legitimate role of critics" of democracy may be difficult to define, but one "approach is to divide critics into 'good internal' critics (those who call upon the constitutional regime to be true to its own highest principles) and 'bad external' critics who reject the values embraced and nurtured by constitutional democracy".
Since classical antiquity and through the modern era, democracy has been associated with "rule by the people", "rule by the majority", and free selection or election, either through direct participation or elected representation, respectively.
Political thinkers have approached critiques of democratic political systems from different perspectives. Many times it is not necessary to oppose democracy by its simplest definition – "rule by the people" – but, rather, seek to question or expand this popular definition. In their work, they distinguish between democratic principles that are effectively implemented through undemocratic procedures; undemocratic principles that are implemented through democratic procedures; and variations of the same kind. For instance, some critics of democracy would agree with Winston Churchill's famous remark, "No one pretends that democracy is perfect or all-wise. Indeed, it has been said that democracy is the worst form of government except all those other forms that have been tried from time to time." Other critics may be more prepared to describe existing democratic regimes as anything but "rule by the people".
Leading contemporary thinkers in critical democratic theory include Jürgen Habermas, Robert A. Dahl, Robert E. Goodin, Bernard Manin, Joseph Schumpeter, James S. Fishkin, Ian Shapiro, Jason Brennan, Hélène Landemore, and Hans-Hermann Hoppe.
Critics of democracy have often tried to highlight democracy's inconsistencies, paradoxes, and limits by contrasting it with other forms of governments such as a less democratic epistocracy or a more democratic lottocracy.
