The temptation toward paternalism is one that I feel keenly. And I think  that paternalism can be justified in some situations. So it is in important measure to cause myself to examine my own motives and cause myself second thoughts on that front that I post here what John Stuart Mill writes in the introduction to On Liberty about the paternalistic temptation:

The ancient commonwealths thought themselves entitled to practise, and the ancient philosophers countenanced, the regulation of every part of private conduct by public authority, on the ground that the State had a deep interest in the whole bodily and mental discipline of every one of its citizens; a mode of thinking which may have been admissible in small republics surrounded by powerful enemies, in constant peril of being subverted by foreign attack or internal commotion, and to which even a short interval of relaxed energy and self-command might so easily be fatal, that they could not afford to wait for the salutary permanent effects of freedom. In the modern world, the greater size of political communities, and above all, the separation between spiritual and temporal authority (which placed the direction of men’s consciences in other hands than those which controlled their worldly affairs), prevented so great an interference by law in the details of private life; but the engines of moral repression have been wielded more strenuously against divergence from the reigning opinion in self-regarding, than even in social matters; religion, the most powerful of the elements which have entered into the formation of moral feeling, having almost always been governed either by the ambition of a hierarchy, seeking control over every department of human conduct, or by the spirit of Puritanism. And some of those modern reformers who have placed themselves in strongest opposition to the religions of the past, have been noway behind either churches or sects in their assertion of the right of spiritual domination: M. Comte, in particular, whose social system, as unfolded in hisSysteme de Politique Positive, aims at establishing (though by moral more than by legal appliances) a despotism of society over the individual, surpassing anything contemplated in the political ideal of the most rigid disciplinarian among the ancient philosophers.

Apart from the peculiar tenets of individual thinkers, there is also in the world at large an increasing inclination to stretch unduly the powers of society over the individual, both by the force of opinion and even by that of legislation: and as the tendency of all the changes taking place in the world is to strengthen society, and diminish the power of the individual, this encroachment is not one of the evils which tend spontaneously to disappear, but, on the contrary, to grow more and more formidable. The disposition of mankind, whether as rulers or as fellow-citizens, to impose their own opinions and inclinations as a rule of conduct on others, is so energetically supported by some of the best and by some of the worst feelings incident to human nature, that it is hardly ever kept under restraint by anything but want of power; and as the power is not declining, but growing, unless a strong barrier of moral conviction can be raised against the mischief, we must expect, in the present circumstances of the world, to see it increase.
