A fish probably has no means of apprehending the existence of water; it is too deeply immersed in it.

The properties which differentiate living matter from any kind of inorganic imitation may be instinctively felt, but can hardly be formulated without expert knowledge.

The amount of sophistication varies according to the quality of the medium, and to the state of the same medium at different times; it must be attributed in the best cases physiologically to the medium, intellectually to the control.

Basing my conclusions on experience I am absolutely convinced not only of survival but of demonstrated survival, demonstrated by occasional interaction with matter in such a way as to produce physical results.

Any person without invincible prejudice who had the same experience would come to the same broad conclusion, viz., that things hitherto held impossible do actually occur.

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.

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.
