What is Spiritism?

Spiritism as defined by Allan Kardec is truly a remarkable science able to aid the serious student on holistic and spiritualist disciplines to sort out opinions from facts and challenge dogma, blind faith, mysticism and taboos. Kardec was a remarkable scientist who conducted his studies of spiritual phenomena with rare lucidity, open mind and rationality. His studies have a strong influence to me and that's why I decided to put out my own short version of  "What is Spiritism", highlighting a few points that is often missed. I hope you like it!
