"Are you a person—with volition and maybe some stubbornness 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 it’s 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." — Thomas Covenant (in Stephen R Donaldson's The One Tree)
