Everyone I know is jam packed with information gleaned from their individual life experiences. This is one of the things that make us well … unique individuals. But there is no central knowledge base for us to use … or that we are all willing to use anyway. Information is not of itself knowledge (can be) because it is too subject to embellishments from a multitude of sources … usually from some higher authority or another. If that is the case, the first thing I would think of would be to question the veracity of that said authority … I seem to have been born a doubter. The real problems with human communications are the preconceived ideas we all have about most things we are willing to discuss. If there is a political, religious, social, racial (etc.) line you refuse to cross in your search for the truth … then you will never understand the truth behind your beliefs or gain as much knowledge as is humanly possible … after all is said and done … we are only human. What is it that causes people to put up such restrictive barriers if they are really interested in the truth??? The only thing I can see ... is the exact opposite. I prefer to do my own thinking as well and logically as I can is all.
