The hypothesis of surviving intelligence and personality - not only surviving but anxious and able with difficulty to communicate - is the simplest and most straightforward and the only one that fits all the facts.

Life must be considered sui generis; it is not a form of energy, nor can it be expressed in terms of something else.

Death is the end of a stage, not the end of the journey. The road stretches on beyond our comprehension.

The discovery which has been pointed to by theory is always one of profound interest and importance, but it is usually the close and crown of a long and fruitful period, whereas the discovery which comes as a puzzle and surprise usually marks a fresh epoch and opens a new chapter in science.

The old series of sittings with Mrs. Piper convinced me of survival for reasons which I should find it hard to formulate in any strict fashion, but that was their distinct effect.

If the 'Principle of Relativity' in an extreme sense establishes itself, it seems as if even Time would become discontinuous and be supplied in atoms, as money is doled out in pence or centimes instead of continuously;-in which case our customary existence will turn out to be no more really continuous than the events on a kinematograph screen;-while that great agent of continuity, the Ether of Space, will be relegated to the museum of historical curiosities.

Death is not a foe, but an inevitable adventure.
