The body acts upon the mind, and the mind upon the body in so many, and in such mysterious ways, that I cannot differentiate between them. But of one thing I am quite certain, and it is this: that the best way to learn something of a criminal’s mind is to ascertain everything possible with regard to his body.

In prison this can easily be done, for in prison there is an abundance of time, ample opportunity, and a sufficiency of means for this interesting study. In one Continental prison this is done. There the doctor, not the governor, is the most important personage. From him I sometimes get very instructive communications. The author of the “manual” quoted tells us “that it is his aim to present such a psychology as will deal with all states of mind that might possibly be involved in the determination and judgment of crime.” This is a large order, for he promises an impossibility. I marvel at his temerity, I am then struck by his audacity. But on consulting his index and searching his five hundred pages I admire his prudence, for he never attempts to keep his promise. I find no reference to the influence that physical disease, affliction or deprivation exercises upon the mind. Of epileptics he has nothing to say. He ignores afflictions! Of the blind, the deaf and dumb he is apparently unaware; the cripple, the hunchback, the maimed, the one-armed, the one-legged, the sufferers from sunstroke, and the vast army whose lives have been spoiled through physical accidents—of their psychology we are told nothing.

Yet every one knows, or might know, that their psychological condition is absolutely dominated by their physical condition. In each of them physical nature has been outraged, it has been assaulted; and Nature, knowing no pity, hits back again with a vengeance.

We know, or we might if we cared to know, that these unfortunates, having suffered loss, must receive compensation of some kind, and if that compensation be not of a comforting and inspiring character, including training, education, control and new favourable developments, they become potential criminals. Their wits become sharpened to deceive, their tempers violent, explosive and dangerous. Some one has said, “I am my body.” While this may not be wholly true, there is still a world of truth in the statement. So I again suggest that before we try to grope in the dark recesses of the mind, we set to work to learn more of the body, for that is an open book.

Believe me, it is given to very few to bear about with them a deformed, mutilated or afflicted body without their minds becoming changed also.

Verily, the writers of our old fairy tales and our early novelists were not very far wrong. Have any of my readers ever walked through Parkhurst prison? It is a sort of convalescent home for criminals—a sanatorium, if you will, in the Isle of Wight.

If you have not, then come with me in imagination! Never mind the building, take no heed of the officials, let us concentrate our attention on the prisoners, the criminals, for they are all undergoing penal servitude.

You gasp! and well you may. You never saw such a strange, pitiful mass of smitten humanity! Well! that is something to be thankful for.

“Do you want any specialist in psychology to reveal the working of their queer minds?” “No,” you say, “their poor bodies reveal their minds.” “But they are convicts.” “Oh, no,” you say, “surely they are patients.”

And patients they ought to be; but convicts the law declares them, and convicts they will remain till their smitten bodies and poor minds part company.
