The path to discovery
When we have no idea about the things of the world, we can either ask other people or look for information that gives the answer to our questions. And even if people give concrete answers and books provide specific solutions to problems that you ask, you still have a portion in your mind that is not satisfied. This is, mostly, how people think. Unless you see it for yourself, touch it, and hear it, you would not completely believe that it is true. This is really how men are built. You have to ask questions, look for information, then explore. This is also what makes our lives worthwhile. If we do not see for ourselves, travel, and be adventurous, we are not really living our lives but merely existing.
