The 30th anniversary of the GIRI meetings was celebrated in Amsterdam, - an old city where René Descartes resided 500 years ago, who framed the distinction between ‘matters real’ and ‘matters mental’, a separation that still haunts Western science. Besides, Descartes originated from France where the GIRI was established in 1987 by a group of ‘material scientists’ – so history made full circle… ...So this meeting brought together some key jigsaw pieces that explain the effect of highly diluted solutions in the human ill organism. And I mention ‘ill’ here on purpose, as the sensitivity of an ill person is totally different from that of a healthy person. I hope this inspiring meeting will stimulate even more cooperative projects than already feature the GIRI.
