"That some leader dangerous to the basic institutions of American society would arise, Lincoln thought inevitable. Safeguarding these institutions would require a public sufficiently united, sufficiently attached to freedom, and sufficiently wise, "to successfully frustrate his designs." Today it would also require a public sufficiently resistant to incessant criticisms and condemnations of their society for failing to achieve cosmic justice. Moreover, if the dangers in our own times were limited to those of "towering genius," there would be much less danger than there is. However, all that is needed are towering presumptions, which are increasingly mass-produced in our schools and colleges by the educational vogue of encouraging immature and inexperienced students to sit in emotional judgment on the complex evolution of whole ages and vast civilizations."
