Quotes from past Metapsychics Researchers –
I am absolutely convinced of the fact that those who once lived on earth can and do communicate with us. It is hardly possible to convey to the inexperienced an adequate idea of the strength and cumulative force of the evidence. Sir William F. Barrett, F.R.S.
The facts revealed necessitate the complete overthrow of the materialistic physiology and conception of the universe. – Dr. Gustave Geley, Metaphysic Institute, Paris.
I tell you we do persist. Communication is possible. I have proved that the people who communicate are who and what they say they are. The conclusion is that survival is scientifically proved by scientific investigation. – Sir Oliver Lodge.
