Written in 1915: In many cases, there is doubt as to the organic nature of the paralysis. Numerous cases occur to which, in civil practice, the term “hysterical” would be applied. Many of the patients are, however, men who have proved their bravery in the field, and it seems to me that “psychical” is a fairer term to use. The frightful sights and sounds of a battle-field, combined with some amount of actual personal injury, undoubtedly inflict at times a psychical trauma, which in all probability could be shown to have a definite physical basis, had we means fine enough to investigate it. Nothing could be further from the truth than to suggest any trace of malingering in such cases, yet it is undoubtedly true that in many instances that paralysis would vanish under sufficient mental stimulus - such as the classical “house on fire.”
