Letters I found on the internet

I try to include the original source.

[1] There are 2 versions: One including the letters sent by the turkish anarchist and one only including Ted's answer.

[2] The auction text: 11 April 2010 letter from Unabomber Ted Kaczynski, who writes his full name on the front of letter and signs, casually, ''Ted'' on verso. In the letter Kaczynski rebuffs the recipient for writing about personal details instead of focusing on resisting the cause. Letter, sent from prison, reads, in part: ''I don't correspond with people for fun or friendship. I correspond with them for the purpose of resisting the technoindustrial system and for that purpose alone...'' Two 8.5'' x 11'' pages, front and verso. Fine condition.
