Western civilization has moved inexorably away from the Dark Ages and in the general direction of modernity. A lot of good things happened over that time. Some of those good things have been the result of inventions and scientific advancements. Yet just as many have been the result of evolving thought about humans and how we should interact with one another. This movement led away from cruel fiefdoms and total subjugation beneath kings and toward the notion that humans should be able to determine their own lives. The invention of the movable press allowed the mass production of books and pamphlets, which, in turn, led to greater enlightenment and debate. It forced people to confront other people with different ideas, without (always) trying to lop their heads off. Print led to the various revolutions, including the American Revolution, which put the finest point yet on the notion that humans are capable of self-determination and have been granted rights by God Himself to govern themselves. I haven't seen a cat accomplish any of this.
