Your computer doesn’t know a binary string from a ham sandwich. Your math book doesn’t know algebra. Your Rolodex doesn’t know your cousin’s address. Your watch doesn’t know what time it is. Your car doesn’t know where you’re driving. Your television doesn’t know who won the football game last night. Your cell phone doesn’t know what you said to your girlfriend this morning. ¶ People know things. Devices like computers and books and Rolodexes and watches and cars and televisions and cell phones don’t know anything. They don’t have minds. They are artifacts — paper and plastic and silicon things designed and manufactured by people — and they provide people with the means to leverage their human knowledge. ¶ Computers (and books and watches and the like) are the means by which people leverage and express knowledge. Computers store and process representations of knowledge. But computers have no knowledge themselves.
