我的一生被三种简单而又无比强烈的激情所控制:对爱的渴望,对知识的探索和对人类苦难的难以抑制的同情。这些激情像狂风,把我恣情吹向四方,掠过苦痛的大海,迫使我濒临绝望的边缘。
Three passions, simple but overwhelmingly strong, have governed my life: the longing for love, the search for knowledge, and unbearable pity for the suffering of mankind. These passions, like great winds, have blown me hither and thither, in a wayward course, over a great ocean of anguish, reaching to the very verge of despair.
