What does the bible say about thinking?

I read books on economic thinking.
I read books on doctor's thinking.
I read books on teacher's thinking.

Many people claim the horrors and disasters of TV, unfiltered advertisements or even the lack of literature. Side effects cannot be clearly sighted, but all claim a sub-conscious altering of the mind, the patterns and rails of thought patterns being hijacked by over-planned media and capitalism.

But Really.

What does the bible say of our thought patterns?

The bible does talk about the heart, talks about the machinations of the putrid evil of the faithless. But does it talk about logic, fact, cognition? It talks about blindness, but is that a heart issue or a lack of a logical thought process?

And, if we should consider ourselves responsibile christians, how should we go about these processes.

Guesses:
Look at "dwell", "consider", "ponder", and I would even submit "wait"
