Unfortunately, the relation between the ends and the means remains widely misunderstood.  Many of those who profess the most individualistic objectives support collectivist means without recognizing the contradiction.  It is tempting to believe that social evils arise from the activities of evil men and that if only good men (like ourselves, naturally) wielded power, all would be well.  That view requires emotion and self praise-easy to come by and satisfying as well. To understand why it is that ‘good’ men in positions of power will produce evil, while the ordinary man without power but able to engage in voluntary cooperation with his neighbors will produce good, requires analysis and thought, subordinating the emotions to the rational faculty.
