If this is correct, then it is conclusively true that wet equals dry, light equals dark, tall equals short, ugly equals quite beautiful, intelligent equals moronic, etc.
If an opposite is not an opposite, then this theory has been proved incorrect. Nothing exists. This entry does not exist. You do not exist. I do not exist. Zaphod Beeblebrox does not exist. The Guide does not exist. But then again it does. And so on. It is an infinite cycle from nothing to something and from something to nothing. You are everything but nothing. Alright, I believe I am going a bit beyond the call of duty. Which is nothing.
Oh, but it is something.
A summary: Life is a cycle of existence and lack thereof.
