That spiritistic ‘literature’ which has led astray…so many weak and impressionable minds.

The only perfectly ascertained fact of spiritistic science is the rap.

New support for unfounded spiritualistic and spiritistic chimeras.

No living person can enter the perception of his fellow save as a body. This holds in the most spiritistic of systems. Even the bodyless dead must have a living body for a medium of their manifestation; nor can any event of heaven or hell make sense except by way of bodily reference.

All conventional philosophies assume the existence of a real world — a reality apart from knowers and their knowing — although not all indulge themselves in speculations concerning ontological matters. I make this claim even of the most spiritistic forms of idealism, in that to speak about the universe at all implies someone speaking and something spoken about — these two constituting the existent reality.
