Are we told that science cannot grasp these phenomena to investigate them? The statement is not true. They cannot be grasped at any time by anybody, but no more can the depths of stellar space be fathomed by whoever chooses whenever it suits his leisure. Great telescopes are scarce; nights perfectly fitted for observation must be waited for with patience. But when they come, the men who have got the telescopes take observations and make reports, and their records are studied by other astronomers, and used as the foundation of theories, as the raw material of current knowledge. If similar methods were adopted with even the crudest spiritualistic, not to speak of scientific, research in occult mystery, the world at large would not be blundering about as it is, with absurd denials of facts known to thousands. Clairvoyance again, by flights of perception through the invisible world, bridges gulfs that are materially impassable. But what does modern culture know of it? As a scientific fact, it is enormously more certain than the existence, for example, of the satellites of Mars; but who disputes the latter fact? They have been seen, those satellites, if they are not seen easily or often, and therefore their existence has been established. But five newspapers out of six in the present day—barometers of prevailing belief—would profess to disbelieve in clairvoyance if the subject had to be mentioned; to _disbelieve_ in that which is an elementary truth having to do with the most easily accessible region of supermaterial knowledge!
