Maybe you're reading the wrong books. Or maybe you don't know what books exist. The written word enables human beings to communicate ideas across time and space. It's totally democratic, there's no entry requirements on a book, the information's all there for you and you can fit it into your own ideas and expand your horizons and understanding about things you'll never be able to experience otherwise, or maybe learn about things you didn't know existed. The information can help you develop your own ideas, refine them, expand them. What's the alternative, believing that everything important is contained inside your own head, needing no input or collaboration with the outside world, that you can't learn anything from anything except your own direct experience? I don't think civilisation would have quite got as far as it has without sharing ideas.
