Copernicus’ Secret by Jack Repcheck
Copernicus is famous for kicking off the scientific revolution by proclaiming his heliocentric (sun-centered) theory of the universe. Someone who reads much about the scientific revolution that came about in the 15th and 16th centuries will come across his name. Even so, there are many misconceptions regarding the astronomer.
The main misconception is that Copernicus was prosecuted for his heliocentric theory. Though his book on the subject was eventually banned by the Roman Catholic Church for about two centuries, he was an official of the church who had taken first orders and he was mostly well received in both the scientific and religious communities of his day. His primary book on the subject wasn’t even published until the very end of his life.
Copernicus had his share of troubles. One he brought on himself by keeping a mistress. His ordination included a vow of celibacy. The other came from being an official of Catholic government in a territory surrounded by recently converted Lutheran countries.
Oddly enough, it was Lutheran mathematics professor who helped the Catholic astronomer prepare is book for publication. Joachim Rheticus was educated at Wittenberg where he taught astronomy and astrology (astrology was widely accepted at the time and practiced by almost all astronomers). He was given a leave of absence, which he stretched out for three years before returning to his duties, and took it upon himself to find Copernicus and become his student.
This was a dangerous situation for Rheticus, Lutherans were banned from Copernicus’ home territory of Warmia, and doubly so for Copernicus because of his role as a church and civil official. That he housed a Lutheran seemed to have been tolerated better than his long affair with a woman.
Copernicus’ Secret is an interesting look at the astronomer’s professional life and its development. It touches on his personal life, especially his long-term relationship with the mistress who lived with him until he was forced to break off the relationship, but this part is much weaker. This may be because Copernicus was a private person. Even so, Repcheck show’s that trouble Copernicus faced had more to do with his personal life and the political tensions of the day than with his proposal of a heliocentric universe.

Descarte’s Secret Notebook by Amir D. Aczel
A famous mathematician with suspected ties to a secretive cabal of global reformers dies from possible poisoning at the hand of a doctor employed by a European power. A French official surveys his papers, including a coded notebook, and has them quietly sent to the safekeeping of a relative. Years later, another brilliant mathematician, suffering from attacks on his reputation, seeks out the notebook to uncover its secrets.
It sounds like the plot of a thriller. Amir Aczel uses it to frame his biography of philosopher and mathematician René Descartes.
Descartes’ greatest hit as a philosopher was, “Cogito, ergo sum” (I think, therefore I am). He was a leader in rationalism, a philosophy that emphasizes the discovery of truth by use of reason. His method focused on methodical doubt by which he aimed to find truth (to him, all knowledge was connected, not discreet, unrelated truths) by reasoning out those things that could not be doubted. Thusly he reasoned his existence because he couldn’t very well doubt it when he was sitting there thinking about it. His method set him against the prevailing philosophy of the day, scholasticism, which focused on learning from authoritative figures and sources, particularly Aristotle.
High school algebra students will immediately recognize Descartes’ contribution to math. From today’s perspective, it may be hard to understand why it was such a big deal in the 17th Century. Descartes created analytic geometry, which uses algebraic equations to describe and understand geometric shapes. Before this, geometry and algebra were distinct fields, not parts of a unified mathematics. As part of this, he gave us Cartesian coordinates, the familiar x,y graph that has makes so many high school kids cross-eyed. Despite complaints that they’ll never use it, behind the scenes Cartesian coordinates are ubiquitous.
Descartes was not part of a secret society. He was a devout Catholic and was careful not to publish anything that would put him in direct conflict with the church. Even so, the writings of the Rosicrucians, a group of philosophers who sought political and religious reform and the advancement of science, influenced him. He even knew one of the brotherhood, though he may have been unaware of it. Despite his efforts to distance himself from the Rosy Cross, his books used terms that made some believe he was a Rosicrucian and his notebook included alchemical symbols that the group used.
Gottfried Leibniz, co-creator of calculus, was under attack from proponents of Isaac Newton, who independently created calculus contemporaneously with Leibniz. Other accused Leibniz of deriving his work from Descartes, which is why he diligently tracked down the Frenchman’s papers.
What did Descartes’ secret notebook contain? Leibniz handily decoded it. Descartes discovered Euler’s theorem. For polyhedrons, the sum of the number of faces (F) and the number of vertices (V) minus the number of edges (E) is 2 (F + V – E = 2). Descartes kept his discovery secret because some may have construed it as supporting a theory of Johann Kepler that used regular polyhedrons to describe planetary orbits in a Copernican model of the solar system. This was contrary to the teaching of the church, which Descartes wanted to avoid because of his personal devotion and because conflict with the Inquisition could be a career-ending (and life-ending) move.
Amir D. Aczel also wrote Chance.

Dark Nights of the Soul by Thomas Moore
Psychotherapist Thomas Moore, a former Catholic monk, expressed some unusual ideas about depression in his book Dark Nights of the Soul. I feel I should preface my comments with a caveat. If you have clinical depression, or think you might, please seek help from an appropriate professional in psychology, counseling or medicine. If you need medication, take it. I think you can undertake the kind exploration that Moore suggests without abandoning traditional therapies, especially if you need them to mitigate extreme symptoms that threaten your life and health.
As an alternative to this approach, Moore focuses on the opportunities in depression, persistent dark moods and hard times—dark nights may take any of these forms—as opportunities to mature, grow and heal the soul. Instead of rushing to get by depression and get better, sit with it, explore it and learn from it. It could be a calling from your truest self to examine your life and become deeper, more engaged person. Instead of a curse, the dark night may turn out to be a gift.
Moore draws heavily on religion and mythology. He also discusses dreams. In the mode of Carl Jung, he sees value in symbols to illuminate what is going on in your life, as well as the value of symbolic and ritual action.
For instance, he draws a model from myth for the experience of depression. It begins with a separation or departure. One feels cut off, alone or isolated, especially from normal life. In a myth, this leaving of normal life is the beginning of an adventure. The mythic adventurer enters a new world, often and underworld, where he is challenged and gains a new perspective. These challenges help him discover who he really is. It is helpful to be able to move back and forth between the underworld and night to the upper world and day, to be able to benefit from the darkness without being consumed by it. In the end, the adventurer returns to his normal life, but it is not always easy because he is changed by his experiences in the underworld. Hopefully the lessons of his dark night well help him integrate his new life with the best of his old home.
Perspective seems to be one of the big benefits of a dark night. Everything looks different in the dark. You can reevaluate what things mean to you, the seeming trash that is truly a treasure and the seeming treasure that is truly worthless. It's a chance to clear out the clutter. It pushes you to accept that the darkness is real and part of you. Because the underworld is essentially your inner life, you can find by exploring it those places that are abandoned, ignored, neglected or run over roughshod by your outer life.
Each chapter takes on the exploration of various aspects of life that may bring about a dark night. These include love, sex, marriage, family, art, beauty, anger, disease and aging.
These journeys into darkness need not be undertaken alone. Sometimes you need professional help. The honesty and vulnerability needed to properly explore the dark parts of yourself could help you be a more open person and deepen your relationship with others. To succeed in the journey, it helps to have the attitude toward yourself of a graceful healer participating in your own life, and that attitude can make you receptive to the healing grace of others and your role as a helper of others.

The Faith of JFK edited by T. S. Settel
The Faith of JFK is a compilation of segments of John F. Kennedy’s speeches and writings and related material, mostly from the time of his presidency. One might hope for an analysis of his faith and its influence on his public life, but perhaps it was too early for such considerations in 1965.
The segments of Kennedy’s speeches and proclamations gives one a sense of his espoused views on the subjects of his religion, American government and foreign affairs, which he sometimes presented forcefully. On a few occasions, the quotes are so short as to have almost no context except to show that he quoted some source. Generally, the edited segments strike a nice balance between being representative and brief.
The largest segment of the book juxtaposes parts of Kennedy’s speeches in which he quoted scripture with the verses from the Bible. Sometimes they show a thoughtful reflection on how biblical ideas applied to the issues at hand (probably this was something of the intent of the collection, to demonstrate the president’s adherence to both Catholic and American ideals). Often, the biblical quotations are selected to support a point in the speech, but when one reads the passage from which it is taken it appears to be at best tangentially related or actually related to another subject altogether. This is far too common even today. Even in this second case, this chapter is illuminating, because seeing the sometimes tenuous connection between the Bible and the speech that quotes it can help one more clearly see what each is really addressing.
The best parts of the book are those that don’t relate to Kennedy’s quotations of the Bible, poems or other literature. Kennedy seemed to express his ideals and policies most eloquently when he was not leaning on other sources. In those times, he might have most clearly expressed his true views, without obscuring them with quotes that carry their own weight and meaning.
