Meaning happens when the purposes of the writer come together with what the reader thinks is important. Since all aspects of any one thing cannot be perceived all at once, we focus our attention on this or that aspect of a thing depending upon what we want to achieve. This is why we can read a particular text many times and find new insights each time.
This is also why we cannot agree on what the Second Amendment of the U.S. Constitution means. The amendment reads:
A well regulated Militia, being necessary to the security of a free State, the right of the people to keep and bear Arms, shall not be infringed.
Many of us who support restriction on the kind of guns and the size of ammunition magazines that private citizens can own focus attention on the clause, “a well regulated Militia.” On the other hand, many who do not support restrictions on the kinds of guns private citizens may own focus attention on the clause “the right of the people to keep and bear Arms shall not be infringed.”
