What does "public acceptance" here mean?
Does it allude to their confession to spiritual interpretation before the public?
“We have had experience in these latter days of mediums giving themselves up in the same unreserved way to scientific investigation and being betrayed by the investigators, who had not the moral courage to admit those results which would have entailed their own public acceptance of the spiritual interpretation.”
