"Good men (not bad men) consistently acting upon that position would act as cruelly and unjustly as the greatest tyrants. They might in some respects act even worse. Of all tyrannies a tyranny sincerely exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron’s cruelty may sometimes sleep, his cupidity may at some point be satiated; but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience. They may be more likely to go to Heaven yet at the same time likelier to make a Hell of earth. Their very kindness stings with intolerable insult. To be ‘cured’ against one’s will and cured of states which we may not regard as disease is to be put on a level with those who have not yet reached the age of reason or those who never will; to be classed with infants, imbeciles, and domestic animals"

"If I were in authority... indefinitely without having to ask those who are governed whether they like what is being done, then I would not have the slightest doubt that I could govern much more effectively in their interests."
