Unique but incorrect understandings

 When people meet things of the world, people have their own distinctive understanding of the things, whether they recognize it or not. It is only natural that their own unique selves, made by what has happened to them in the past, have different understanding respectively.

 However, apart from the matter of the diversity of such understanding, there exists a matter of whether or not each understanding is right. The bigger problem is that most people mistake their understanding as the right answer. The much bigger problem is that some people say they admit such mistaking, or even advocate that such mistaking should not be made, but do not realize that they are actually making the same mistake.
