# Re: Overcoming Incompleteness

```You are right when it comes to the combination of two independent
systems A and B. What the original poster's idea was a
self-simulating, or self-aware system. In this case, consider the liar
```
I cannot prove this statement

Whilst I cannot prove this statement, I do know it is true, simply
because if I could prove the statement it would be false.

To know that it is true, I am using self-reference about my own proof
capabilities.

I don't think anyone yet has managed a self aware formal system,
although self-reproducing systems have been known since the 1950s, and
are popularly encountered in the form of computer viruses. There has
to be some relationship between a self-reproducing system and a
self-aware system...

Cheers
