John Stuart Mill on Proportional Representation
Two very different ideas are usually confounded under the name democracy. The pure idea of democracy, according to its definition, is the government of the whole people by the whole people, equally represented. Democracy as commonly conceived and hitherto practiced, is the government of the whole people by a mere majority of the people, exclusively represented. The former is synonymous with the equality of all citizens; the latter, strangely confounded with it, is a government of privilege, in favor of the numerical majority, who alone possess practically any voice in the State. This is the inevitable consequence of the manner in which the votes are now taken, the complete disenfranchisement of minorities.
The confusion of ideas here is great, but is so easily cleared up, that one would suppose the slightest indication would be sufficient to place the matter in its true light before any mind of average intelligence. It would be so, but for the power of habit; owing to which the simplest idea, if unfamiliar, has as great difficultly in making its way to the mind as a far more complicated one. That the minority must yield to the majority, the smaller number to the greater, is a familiar idea; and accordingly men think there is no necessity for using their minds any further, and it does not occur to them that there is any medium between allowing the smaller number to be equally powerful with the greater, and blotting out the smaller number altogether. In a representative body actually deliberating, the minority must of course be overruled; and in an equal democracy (since the opinions of the constituents when they insist on them, determine those of the representative body) the majority of the people, through their representatives, will outvote and prevail over the minority and their representatives. But does it follow the minority should have no representatives at all? Because the majority ought to prevail over the minority, must the majority have all the votes, the minority none? Is it necessary that the minority should not even be heard? Nothing but habit and old association can reconcile any reasonable being to the needless injustice. In a really equal democracy, every or any section would be represented, not disproportionately but proportionately. As majority of the electors would always have a majority of the representatives; but a minority of the electors would always have a minority of the representatives. Man for man, they would be as fully represented as the majority. Unless they are, there is not equal government, but a government of inequality and privilege; one part of the people rule over the rest; there is a party whose fair and equal share of influence in the representation is withheld from them contrary to all just government, but above all, contrary to the principle of democracy, which professes equality as its very root and foundation.
The injustice and violation of principle are not less flagrant because those who suffer by them are a minority; for there is not equal suffrage where every single individual does not count for as much as any other single individual in the community. But it is not only a minority who suffer. Democracy, thus constituted, does not even attain its ostensible object, that of giving the powers of government in all cases to the numerical majority. It does something every different: it gives them to a majority of the majority; who may be, and often are, but a minority of the whole. . . . If democracy means the certain ascendancy of the majority, there are no means of insuring that, but by allowing every individual figure to tell equally in the summing up. Any minority left out, either purposely or by the play of the machinery, gives the power not to the majority, but to a minority in some other part of the scale.
And it is not solely through the votes of minorities that this system of election would raise the intellectual standard of the House of Commons. Majorities would be compelled to look out for members of a much higher calibre. When the individuals composing the majority would no longer be reduced to Hobson's choice, of either voting for the person brought forward by their local leaders, or not voting at all; when the nominees of the leaders would have to encounter the competition not solely of the candidate of the minority, but of all the men of established reputation in the country who were willing to serve; it would be impossible any longer to foist upon the electors the first person who presents himself with the catchwords of the party in his mouth, and three or four thousand pounds in his pocket. The majority would insist on having a candidate worthy of their choice, or they would carry their votes somewhere else.
[With proportional representation] the champions of unpopular doctrines would not put forth their arguments merely in books and periodicals, read only by their own side; the opposing ranks would meet face to face to hand, and there would be a fair comparison of their intellectual strength, in the presence of the country. It would then by found out whether the opinion which prevailed by counting votes, would also prevail if the votes were weighted as well as counted. The multitude have often a true instinct for distinguishing an able man, when he has the means of displaying his ability in a fair filed before them. If such a man fails to obtain at least some portion of his just weight, it is through institutions or usages which keep him out of sight.
[Some critics of proportional representation] are unable to reconcile themselves to the loss of what they term the local character of the representation. A nation does not seem to them to consist of persons, but of artificial units, the creation of geography and statistics. Parliament must represent towns and counties, not human beings. But no one seeks to annihilate towns and counties. Towns and counties, it may be presumed, are represented, when the human beings who inhabit them are represented. Local feelings cannot exist without somebody who feels them; nor local interests without somebody interested in them. If the human beings whose feelings and interests these are, have their proper share of representation, these feelings and interests are represented, in common with all other feelings and interests of those persons. But I cannot see why the feelings and interests which arrange mankind according to localities, should be the only ones thought worthy of being represented; or why people who have other feelings and interests, which they value more than they do their geographical ones, should be restricted to these as the sole principle of their political classification.
