Hi,
Hell yes! The question is - practical value for the person with the gift or for the society? I mean the latter would be the biggie I think. I mean just imagine politics in a world where politicians couldn't lie, or cheat or try to defraud etc. Just the very presence of this magic would be a threat to probably half (maybe all) those who seek power. Then there's justice and criminal trials.I mean with this gift there's no more beyond reasonable doubt - the truth is out there! And how would normal, everyday people go about their lives just knowing that there are people about who can read their minds? Think of a society in which people are forced to be truthful in everything because of this. And then think of all those who want to get rid of them!
Cheers, Greg.
