the mind's a very versatile tool. just as a claw hammer can extract nails as well as put them into walls, so can imagination be used to see through deception – as well as to create it. i usually know what i'm doing with a hammer.. but occasionally, i assume one process is taking place inside my head only to realise, belatedly, that it was actually another. there's a whole lot of doubt about what i'm seeing and thinking..
