Question: You can go invisible when nobody is looking at you, how would you use this power?
Answer: I really would like to acquire this ability, to be able to move undetected as one who wades into water without causing even a ripple.
Then I could enter the desires, viewpoints of others, collecting a “holographic” image of the world, that is undisturbed, undistorted by my inherently self-centered, subjective point of view.
This would be similar to the principle of “do no harm”, getting to know others and through them the world, without touching, influencing anything.
