I do not believe demons will ever be directly detected by scientific instrumentation, but the evidence of their presence can be inferred by changes in peoples behavior. Schizophrenics often hear voices with no apparent observable reasons. However, demons and organic reasons can be implied.

In regard to demons and schizophrenia most psychiatrists believe that schizophrenia is caused by chemical and physical disturbances of the brain. Indeed, brain scans have found significant differences between the brains of normal persons and schizophrenics. But here again there is a hidden materialist assumption, as well as the logical fallacy of assumed causality. When two things occur, one does not necessarily cause the other. A famous case of this was the law suit brought against Corning for supplying material to make breast implants. Some woman with these implants developed breast cancer, and claimed that the implants caused the cancer. Statistical evidence showed that woman with implants did not develop cancer at a higher rate than those without implants. Although some did, as in any group of women (i.e. women who eat carrots). But the lawyers were so cleaver and manipulative, and the cancerous women so piteous that the jury voted against Corning and made them pay a huge amount for damages.

Similarly, in the case of brain irregularities and schizophrenia, the presence of abnormal chemistry and structure of the schizophrenic’s brain does not mean those factors are the cause. In my hypothesis they are the signs of demonic presence. That is, that demonic entrance into the person stopped normal brain development and caused various chemical imbalances. The vector is: demon to brain, to abnormal brain. This of course could only be proven by large scale tests, including before and after scans of voice hearing schizophrenic patients who undergo deliverance prayer and the laying on of hands to restore normality to the brain. Such an experiment would not show demons directly, but the “trails” of their destructiveness.
