It begins by explaining that according to Spiritism, the meaning of life is transcendence through successive lives on Earth in order to develop our spiritual potential. It then discusses how Kardec discovered the subconscious through his research on psychic phenomena, pre-dating Freud's work. Finally, it notes that some psychiatrists criticize Spiritism for invading their domains, but that Kardec in fact raised the problem of the subconscious scientifically before Freud through his Spiritist research.
