It is little short of a miracle that modern methods of instruction have not already completely strangled the holy curiosity of inquiry.... I believe that one could even deprive a healthy beast of prey of its voraciousness if one could force it with a whip to eat continuously whether it were hungry or not.
There are two ways of resisting war: the legal way and the revolutionary way. The legal way involves the offer of alternatinve service not as a privilege for a few but as a right for all.
