How do I know what I know?

Knowledge, by the standards of the American dictionary, is defined as the psychological result of perception and learning and reasoning. As such, it's safe to say that what one knows is subjective, and wholly depends on how much sense they can create from a given idea or result. People tend to question what they do not understand or know, and as such, knowing comes through understanding the answer.

How exactly can one know what they know? The simple answer therefore seems to be that they know a given piece of knowledge when an idea stemming from point 'A'  has supporting evidence to prove a point 'B'. When one knows something, they have all the planks necessary construct a complete rope bridge across. However, many times, people tend to mistake assumptions for knowledge; having some only some of the planks, which may seem complete, but provides instability when walked upon.

Even though knowledge may be subjective and assumptions for the most part, such as with cases regarding religion, society fortunately has come upon certain pieces of evidence that appeal to the majority of it's members. As such, subjective ideology becomes a more or less unanimous knowledge, simply because everyone has opted to accept it. It's never impossible to find or create gaps within bridges, thus it can be argued that as humans, true and absolute knowledge might just be assumptions in the end.
