Read this excerpt from "My Escape from Slavery.”In the first narrative of my experience in slavery, written nearly forty years ago, and in various writings since, I have given the public what I considered very good reasons for withholding the manner of my escape. In substance these reasons were, first, that such publication at any time during the existence of slavery might be used by the master against the slave, and prevent the future escape of any who might adopt the same means that I did. The second reason was, if possible, still more binding to silence: the publication of details would certainly have put in peril the persons and property of those who assisted... My success was due to address rather than courage, to good luck rather than bravery.How does the speaker feel about his early writings about his escape now that he is older?
