Suppose you could send messages back in time to Archimedes of Syracuse, using a chronophone which - to avoid transmitting anachronistic information - transmits the results of executing cognitive strategies, rather than words.
"You have no idea what you're about to discover!" "What you thought is real, is really not the truth!" "You can't imagine the facts!" "What is real, is only real to you!"
Just some ideas. Anna
