 In 1995 , Kaczynski mailed several letters , including some to his victims and others to major media outlets , outlining his goals and demanding that his 50 @-@ plus page , 35 @,@ 000 @-@ word essay Industrial Society and Its Future , abbreviated to " Unabomber Manifesto " by the FBI , be printed verbatim by a major newspaper or journal . He stated that if this demand were met , he would then end his bombing campaign . The document was a densely written manifesto that called for a worldwide revolution against the effects of modern society 's " industrial @-@ technological system " . There was a great deal of controversy as to whether the document should be published , but the United States Department of Justice , along with FBI Director Louis Freeh and Attorney General Janet Reno , recommended publication out of concern for public safety and in hopes that a reader could identify the author . Bob Guccione of Penthouse volunteered to publish it , but Kaczynski replied that , since Penthouse was less " respectable " than the other publications , he would in that case " reserve the right to plant one ( and only one ) bomb intended to kill , after our manuscript has been published . " The pamphlet was finally published by The New York Times and The Washington Post on September 19 , 1995 . Penthouse never published it .
