The Kzinti Lesson was derived from the initial defense of the solar system against the Kzin war fleet. The early human interstellar ships used asteroid-mounted laser launchers to push the ships up to speeds where the Bussard Ramjets worked. These ginormous lasers also served quite well as weapons. <http://www.larryniven.net/kzin/worlds.shtml> That said, I vaguely recall the “Kzinti Lesson” being described differently in “Ringworld”, which, iirc, is the first canonical mention of the thing. Louis has a discussion with Speaker about it. Been a very long time since I re-read Ringworld. -- Bruce Johnson University of Arizona College of Pharmacy Information Technology Group Institutions do not have opinions, merely customs
