参考翻译
This is no time for any man to withdraw into some ivory tower and proclaim the right to hold himself aloof from the problems and the agonies of his society.The times call for bold belief that the world can be changed by man's endeavor,and that this endeavor can lead to something new and better.No man can sever the bonds that unite him to his society simply by averting his eyes.He must ever be receptive and sensitive to the new;and have sufficient courage and skill to fave novel facts and to deal with them.
