The wave existed, only during its "life". The pattern that corresponds to it is real, but non-existent.

Therefore reality contains that which exists, and patterns.

My problem with this scheme is that I think that saying that patterns are non-existent is just a shorthand; patterns are mental objects, and therefore they exist as some cerebral disposition of biological, chemical, physical matter. (There is no pattern of X aside from my mentalization about X).

In my words, the wave existed, only during its "life". The pattern that corresponds to it existed, only during the observer's life.

We end with all-pervasing death; death to that which is real and death to the pattern. Neat!
