Murr on human beings

I know that they make a great deal of something that is supposed to sit in their heads, which they call reason. I am not altogether sure of what exactly they mean by that. But this much is certain: if I am correct in concluding from certain discourses of my master and patron that reason is nothing other than the capacity to act with consciousness, and not to play any dumb tricks, then I would not change places with any human being.
