“Knowledge is a tool, and like all tools, its impact is in the hands of the user.”

“...are you a person - with volition and maybe some stubborness and at least the capacity if not the actual determination to do something surprising - or are you a tool? A tool just serves its user. It's only as good as the skill of its user, and its not good for anything else. So if you want to accomplish something special - something more than you can do for yourself - you can't use a tool. You have to use a person and hope the surprises will work in your favor. You have to use something that's free to not be what you had in mind.”

“Humans are just barely intelligent tool users; Darwinian evolutionary selection stopped when language and tool use converged, leaving the average hairy meme carrier sadly deficient in smarts.”

“Man is a tool using animal. Without tools he is nothing, with tools he is all.”

“Knowledge and ability were tools, not things to show off.”

“...are you a person with volition and maybe some stubbornness and at least the capacity if not the actual determination to do something surpring or are you a tool? A tool just serves it's user, and it's not good for anything else. So if you want to accomplich something special -something more than you can do for yourself - you can't use a tool. You have to use a person and hope the surprises will work in your favor. You have to use something that's free to not be what you had in mind.”
