"If our personality survives, then it is strictly logical and scientific to assume that it retains memory, intellect, and other faculties and knowledge that we acquire on earth...

"...I am inclined to believe that our personality hereafter will be able to affect matter. If this reasoning be correct, then, if we can evolve an instrument so delicate as to be affected, moved, or manipulated...by our personality as it survives in the next life, such an instrument, when made available, ought to record something.”
-Thomas Edison, 1920
