If You Can Read This by Jack Bowen, starting with bumper sticker lines followed by commentary using references to biology, neuroscience, and psychology as well as technology, marketing, and pop culture, provides an accessible way to approach philosophy. The short sections and lively style make it a good bedside book. Jack said that his favorite bumper sticker is "Reading is Sexy"; he ends his commentary on it by saying: "Maintaining an active brain has been proven to ward off Alzheimer's disease - in the use it or lose it mentality of a muscle, reading is like a lively little weight room for the brain."
