| Mind-Shield | ||
| A mental defense or barrier that prevents access to one brain by another person or device. |
As far as I know, this is the first use of the term, if not the concept.
| "You will lower your mind shield. Of course, I don't expect absolutely free access to your brain. I have no objection to your controlling your thoughts on a narrow range all around the subject. But your shield must go down - now! |
