A stupid person has no insight into the connection of natural phenomena, either when they follow their own course, or when they are intentionally combined, i.e., are applied to machinery. Such a man readily believes in magic and miracles.

Context

“Deficiency of understanding is called [pg 028] stupidity. It is just dulness in applying the law of causality, incapacity for the immediate apprehension of the concatenations of causes and effects, motives and actions. A stupid person has no insight into the connection of natural phenomena, either when they follow their own course, or when they are intentionally combined, i.e., are applied to machinery. Such a man readily believes in magic and miracles. A stupid man does not observe that persons, who apparently act independently of each other, are really in collusion; he is therefore easily mystified, and outwitted; he does not discern the hidden motives of proffered advice or expressions of opinion, &c.” source
