Plants don't think. Animals are guided by the power of instinct over which they themselves have no control. Animals have a certain kind of brain that makes it impossible to learn anything except very simple things. No generation of animals ever learns anything from any previous generation. We act like animals when we fail to use this magnificent piece of equipment.
Sterling W SillOne of the most productive things that we ever do in our lives is to think. To be able to think is to be able to decide, to judge, to have opinions and convictions, and to entertain a point of view. To be able to think is to be able to love, to believe, to work, to originate, and to organize.
