There is nothing we can define, other than by comparing and contrasting to our previous experiences. Concsiousness also requires desire, for without desire there would be no reason to attempt something more than once, or to try someting in a different way than has already been recorded.

I do not believe there can be a passive consciousness, as an ability to modify your environment (even in such a small way as a baby moving it's hand for the first time)allows you to create a loop environment where an output (or action) will have a detectable effect via an input channel.

This leaves us in an interesting place.

I think ,therefore I think I am, I think.

I think you think therefore, I think you think you think you are, you think, I think.
