External Impressions
Malebranche’s story is of a woman who, after witnessing a criminal broken at the wheel , a common form of public execution at the time, gave birth to a developmentally disabled child. This child’s limbs were fractured in the same locations as had the criminal’s been broken. One possible medical explanation for this is the congenital disease osteogenesis imperfecta, also known as brittle bone disease, which results from one’s inability to produce type 1 collagen, a protein used in bone creation.
Malebranche also wrote of a woman who from “much gazing at a picture of St. Pius,” had a child who resembled the saint. The explanation of these phenomena was simple: “Children see what their Mothers see, they hear the same Cries, they receive the same Impressions of the Objects, and are moved by the same Passions.”
