When a light goes out/burns out...
what is the NATURAL DEFAULT
to it's non existence.
Do you think that darkness is the default natural state? I think light can be a natural default, because it exists. Ofcourse, the energy and matter that make up light can change into something else, something that may not give any light but still be there. So while we could perceive that space occupied by this energy and matter as darkness, it could nevertheless be filled with something. Darkness and light, I think, have more to do with the senses of vision than they do actual reality. But, with regards to good and evil - why couldn't good exist without evil? Personally, it is my hope that all of existence will one day be free of evil, with one possible exception. That evil would be controlled and used responsibly in a way which would promote the positive development of beings. So, say, if the only way for a being to develop a useful perspective is by experiencing some kind of evil, then this would ultimately be a good thing. But, perhaps there is no truly good use for evil, and equally as effective options are available through the use of good or neutral processes - in which case, good ridance.
