Q: Dear Fr. Fortea, do demons know the future?
A: No. Demons do not have knowledge of future events. In addition, what belongs to human freedom is undetermined; they do not know in advance our free choices. However, since their intelligence is far superior to ours, they can often predict the future simply by observation and deduction. With their superior intelligence, they can see the effects of certain causes whereas we would perceive nothing. Thus, there are times when they can accurately predict what will happen, even though the most intelligent of human beings would not even suspect such a result, no matter how many factors are analyzed in the present. On other occasions, due to the complexities and variability of human action, even the most powerful angelic intellect can be mistaken in its predictions.
