Emanuel Swedenborg's Investigations in Natural Science and the Basis for His Statements Concerning the Functions of the Brain — Reading Notes

Swedenborg's Scientific Range

Ramström opens by cataloging Swedenborg's investigations across mathematics, mechanics, astronomy, geology, mineralogy, chemistry, physics, cosmology, anatomy, and physiology. This breadth is not merely listed but used to argue that Swedenborg's later brain theories grew from a systematic natural-science foundation. The author notes that Swedenborg's anatomical work, especially on the brain, was part of a larger pattern of empirical inquiry. Ramström emphasizes that Swedenborg's approach was not speculative but grounded in the dissection and observation of his era, though he does not claim Swedenborg anticipated modern neuroscience.

The Localization Debate

Ramström scrutinizes Swedenborg's doctrine of brain localization, particularly his claims about the anterior region's role in psychical functions. He compares Swedenborg's brief citations of clinical cases—such as Wepfer's account of a woman who lost speech after a cortical hemorrhage—with the original descriptions. Ramström points out that Swedenborg omitted key details: the lesion's precise location, measurements, and the fact that the woman could still move her right-side extremities. This discrepancy, Ramström argues, weakens Swedenborg's argument for anterior localization. He also notes that Swedenborg's habit of providing detailed introductions to chapters is absent in De Cerebro, possibly due to the work's incomplete state or editorial choices by Dr. Rudolf Tafel.

Sources and Omissions

Ramström traces Swedenborg's anatomical sources, highlighting Thomas Willis's Cerebri anatome (1667) and its portrayal of the corpus striatum. He shows how Swedenborg selectively used earlier authors to support his own theories. A striking example is the case of a youth with right-sided facial paralysis: the original report by Pacchioni noted that the cyst extended from the crown to the temple, indicating an anterior lesion. Swedenborg cited this case but did not include the full details. Ramström suggests that if Swedenborg had provided the complete accounts, his localization claims might have been more convincing. The author's method is to compare Swedenborg's excerpts with the originals, revealing a pattern of simplification that sometimes undermines the evidence.

The Unfinished <em>De Cerebro</em>

Ramström notes that Swedenborg's anatomical work De Cerebro was not fully completed or edited for publication. The missing introduction to a key chapter, which would have contained detailed case reports, was intended for Part II—which was never printed. Ramström speculates that this lacuna may explain some of the weaknesses in Swedenborg's argument. He also mentions that the Royal Swedish Academy of Sciences planned to publish De Cerebro in its edition of Swedenborg's scientific works, which would clarify these questions. This section underscores the provisional nature of the evidence available to Ramström and the reader.

Ramström's monograph is valuable for its forensic approach to Swedenborg's scientific method. By comparing Swedenborg's citations with their originals, Ramström reveals both the strengths and limitations of Swedenborg's empirical work. Readers interested in the history of neuroscience or the intersection of science and religion will find a focused, evidence-based analysis that avoids hagiography or dismissal.

Reading Ramström’s careful tracing of Swedenborg’s brain studies brought back the feel of a school desk by a dusty window, my finger under diagrams in Astronomy for Young Australians — Context and Discussion. Both books share that quiet awe before a system—the way a mind or a sky holds together tighter than we first suspect, a patient architecture.
