In 1917, Edward Clodd analyzed the mediumship of the trance medium Gladys Osborne Leonard and came to the conclusion that Leonard had known her séance sitters before she had held the séances, and could have easily obtained such information by natural means. The British psychiatrist Charles Arthur Mercier wrote in his book Spiritualism and Sir Oliver Lodge (1917) that Oliver Lodge had been duped into believing mediumship by trickery and his spiritualist views were based on assumptions and not scientific evidence.
The suffix Voyant in Clairvoyant does not necessarily imply seeing pictures, graphics or pictorial presentation as such. ‘Seeing’ may also mean ‘understanding’ like in ‘Oh, I see!’ In this context the ability of the clairvoyant medium may also include clairsentience, which means that the clairvoyant medium clearly senses the things and the situations. He experiences a kind of gut feeling about what is going to happen or how a situation can be best tackled to provide good results. https://drive.google.com/file/d/1F-Dbl7jUcRo6ni-O3q1IgUdOkJN-kDM7/view?usp=sharing
In the late 1920s and early 1930s there were around one quarter of a million practising Spiritualists and some two thousand Spiritualist societies in the UK in addition to flourishing microcultures of platform mediumship and 'home circles'. Spiritualism continues to be practised, primarily through various denominational Spiritualist churches in the United States, Canada, Australia and the United Kingdom. In the United Kingdom, over 340 Spiritualist churches and centres open their doors to the public and free demonstrations of mediumship are regularly performed.
