Knowledge is simply a manefestation of the mind. And the mind simply a manifestation of the body. With a single datum you know nothing. Collect them and you still know nothing, but now you have data. Organize a lot of data and you get information...and, you still know nothing. Extrapolate cause-and-effect relationships between sets of information and, for the first time you know something (you have knowledge). This is what Google is still trying to do effectively. But be careful...you still have a long way to go. From a lot of knowledge you need to work hard to generalize principles...then, if you are lucky, you may develop foresight. Over years of charting your course through life with foresight as your guide, your experience will compound. You may experience a rare thing indeed...that is wisdom. With wisdom and long-life, you may achieve enlightenment. But few are those who ever achieve enlightenment. Fortunately, for us mere mortals, working to make a living each day just to get through life...there are some shortcuts. Books that record the collected wisdom of countless generations. Consult their stories and a theme will emerge. One theme; wisdom (and thus knowledge) is not just opinion...it is "knowable" and consistent. It is knowable by the filter of generations and time. Another is, Knowledge, itself, is arrogance. It is our own brain and body believing it knows more than the universe. Knowledge holds our spirit hostage and thus our body and mind hostage as well. With enlightenment, you should find, the truth. The truth that you really know nothing and the person who may seem a moron, is really smarter than you.
