Now it is well known that every advance in scientific knowledge is greeted with mocking laughter. We know the jeers with which even clever men greeted the Marconi claims. It is not so many years ago that a distinguished member of the French Academy of Science rose up amongst his colleagues and pronounced the Edison phonograph to be nothing more than an acoustical illusion. So we are told that soldiers' visions are optical illusions. That is no answer. Call them optical delusions if you like, then the query arises what causes these optical delusions, of which we have countless instances, which inform a man of the hour, and sometimes the manner, of his death? To call an effect by another name does not dispose of the cause of such effect, nor is it any solution of the mystery. Few thinkers now, worthy of the name, seriously dispute the existence of super-natural forces and influences. The whole system of Christianity, of belief in all ages, is founded upon such things. To-day front-rank men are investigating in avenues of research where once they sneered. There is much fraud and cheap talk in ordinary life, but not under fire. Men are not cheap then, nor are they paltry. Strange that where death is busiest the evidence of life beyond and above it all should abound. The invisible, full of awe, is also full of teaching, it is pregnant with whispers. The mind, tuned up to a new tension, receives all kinds of Marconi-like messages. What sends such whispers? Is it that in the moment of supreme self-sacrifice and splendid devotion to duty that spiritual perceptions are sharpened? Who shall say? "He was hit, and he rushed forward shouting, 'Why, there's my----' then he dropped dead, but he saw someone, of that I am sure." So spoke a man of the A.S.C., who saw his comrade die. Deep calls to deep, and if we put our ear to the call we may hear the message. On the battlefield, as in no other place, there is the call of soul to soul, of heart to heart, intensified by all our powers of emotion, which duty calls forth at their best. Tommy Atkins stares more fixedly into the dim future, the greater the gloom the more he searches for the gleam, and sometimes it is vouchsafed to him. There is no doubt that mind calls to mind. After all, time and space are artificial things. They cannot be spiritual barriers. Why should a mother, thinking of her lad at the front in a supreme moment of affection and deep yearning, not be able to do what frequently happens unconsciously among ordinary acquaintances? Often a thought will pass from one mind to another in a moment of silence. The uncanny under fire must take its place among things to be investigated, the evidence is too convincing to be pooh-poohed. Science and philosophy are now boldly entering the dim regions of the occult in search of its laws; on the battlefield Tommy Atkins is already there thinking over weird things and he comes to conclusions, finding the lights by which he steers.
