ABSTRACT
There are many cases in which the subject is warned by visual hallucinations of present danger. The experimental branch of extra-sensory perception shows the same indifference to the time-factor and to the divisions between the telepathic, clairvoyant, and precognitive modes of the faculty as do the spontaneous cases. Extra-sensory perception has every appearance of breaking away from the scheme of the world as the people at present understand it, and of refusing to fall into line with the causal scheme. In the case of Precognition it is more obvious and startling, but in truth the difficulty pervades extra-sensory perception as a whole. Precognition is possible only with regard to future sections of the immovable wires. Free-will acts alter the movable wires and thus, to some extent, the whole of the future.
