Ellen G. White repeatedly affirms in her writings that "the dead know nothing." She bases this on several biblical passages, especially Ecclesiastes 9:5-6, 10 and Psalm 146:4. Here are some key annotated statements from her books: - "The Bible declares that the dead know not anything, that their thoughts have perished; they have no part in anything that is done under the sun; they know nothing of the joys or sorrows of those who were dearest to them on earth." (GC 556.1) - "The word of God declares in positive terms that 'the dead know not anything.' Ecclesiastes 9:5, 6: 'For the living know that they shall die: but the dead know not anything, neither have they any more a reward; for the memory of them is forgotten. Also their love, and their hatred, and their envy, is now perished; neither have they any more a portion forever in anything that is done under the sun.'" (1T 298.1) - "What say the Scriptures concerning these things? David declares that man is not conscious in death. 'His breath goeth forth, he returneth to his earth; in that very day his thoughts perish.' Psalm 146:4. Solomon bears the same testimony: 'The living know that they shall die: but the dead know not anything.' 'Their love, and their hatred, and their envy, is now perished; neither have they any more a portion forever in anything that is done under the sun.' 'There is no work, nor device, nor knowledge, nor wisdom, in the grave, whither thou goest.' Ecclesiastes 9:5, 6, 10." (GC 545.3) - "The Hebrews were expressly forbidden to engage in any manner in pretended communion with the dead. God closed this door effectually when He said: 'The dead know not anything.... Neither have they any more a portion forever in anything that is done under the sun.' Ecclesiastes 9:5, 6. 'His breath goeth forth, he returneth to his earth; in that very day his thoughts perish.' Psalm 146:4." (PP 685.3) Ellen White uses these statements to warn against spiritualism and the idea that the dead can communicate with the living, emphasizing that such beliefs are contrary to Scripture and are a deception.
