How about a little imagination?

I looked around and found this little bit:

We also do a remarkable thing that no other creatures seem able to do: whenever our usual ways to think fail, we can start to think about our thoughts themselves—and if this “reflective thinking’ shows where we went wrong, that can help us to invent new and more powerful ways to think. However, we still know very little about how our brains manage to do such things. How does imagination work?

The Emotion Machine, by Marvin Lee Minsky.

I think this brings up something very important. I would argue that machines cannot be conscious of they are incapable of having an imagination and the ability to reflect on their own thoughts in order to determine new ways of thinking.
