There are now thousands of types of tarot decks to choose from, Hello Kitty to zombies. A traditional deck has 22 Major Arcana (or trumps) which are the archetypal images. There are 56 Minor Arcana cards, sixteen Court or Personality cards; the Kings, Queens, Princes and Pages, just like modern playing cards. There are four elements or suits: Fire, Earth, Air and Water, with 10 cards in each. There are no inherently negative cards.
In 1991, Wendy Grossman in the New Scientist criticized the parapsychologist Stephen E. Braude for ignoring evidence of fraud in mediumship. According to Grossman "[Braude] accuses sceptics of ignoring the evidence he believes is solid, but himself ignores evidence that does not suit him. If a medium was caught cheating on some occasions, he says, the rest of that medium's phenomena were still genuine." Grossman came to the conclusion that Braude did not do proper research on the subject and should study "the art of conjuring."
In 1891 at a public séance with twenty sitters the medium Cecil Husk was caught leaning over a table pretending to be a spirit by covering his face with phosphor material. The magician Will Goldston also exposed the fraud mediumship of Husk. In a séance Goldston attended a pale face materialization appeared in the room. Goldston wrote "I saw at once that it was a gauze mask, and that the moustache attached to it was loose at one side through lack of gum. I pulled at the mask. It came away, revealing the face of Husk." The British materialization medium Annie Fairlamb Mellon was exposed as a fraud on October 12, 1894. During the séance a sitter seized the materialized spirit, and found it to be the Mellon on her knees with white muslin on her head and shoulders.
Theosophy is in opposition to the spiritualist interpretation of evolution. Theosophy teaches a metaphysical theory of evolution mixed with human devolution. Spiritualists do not accept the devolution of the theosophists. To theosophy humanity starts in a state of perfection (see Golden age) and falls into a process of progressive materialization (devolution), developing the mind and losing the spiritual consciousness. After the gathering of experience and growth through repeated reincarnations humanity will regain the original spiritual state, which is now one of self-conscious perfection. Theosophy and spiritualism were both very popular metaphysical schools of thought especially in the early 20th century and thus were always clashing in their different beliefs. Madame Blavatsky was critical of spiritualism; she distanced theosophy from spiritualism as far as she could and allied herself with eastern occultism.
