Does the Bible say anything about a Conscious and Unconscious Mind? Unfortunately, I don't have a rigorous definition of "conscious" and "unconscious" mind, although I think most of us would agree that they exist. 

Question: Is there any verse in the Bible that says anything about the split between conscious and unconscious mind?
2 Peter 2:12 talks about unrighteous men who indulge the flesh. The verse describes them as "creatures of instinct" and "unreasoning animals".

It seems significant that they are described as being moved by "instinct" rather than "reason".

This seems to indicate that it is error to be led by the "unconscious mind" at the expense of the "conscious mind".

I'm not sure "walking" should be classified as "unconscious", though; indeed, if it were, you may walk into traffic without thinking, as a sleep-walker might. ;p
