HP95 – Reformation


ReformationWelcome to episode 95. This episode was a request via email from Jonathan Grunert.

The reformation was a religious revolution that took place in the western church in the 16th century; its greatest leaders where Martin Luther and John Calvin. Having far-reaching political, economic, and social effects, the Reformation became the basis for the founding of Protestantism, one of the three major branches of Christianity.

The world of the late medieval Catholic Church from which the 16th century reformers emerged was a complex one. Over the centuries the church, particularly in the office of the papacy, had become deeply involved in the political life of western Europe. The resulting intrigues and political manipulations, combined with the churches increasing power and wealth, contributed to the bankrupting of the church as a spiritual force. Abuses such as sale of indulgences (or spiritual privileges) and relics and the corruption of the clergy exploited the pious and further undermined the churches spiritual authority.

The Reformation of the 16th century was not unprecedented. Reformers within the medieval church such as St. Francis, Peter Waldo, John Huss, and John Wycliffe addressed abuses in the life of the church in the centuries before 1517. In the 16th century, Easmus of Rotterdam, a great Humanist scholar, was the chief proponent of liberal Catholic reform that attacked moral abuses and popular superstitions in the church and urged the imitation of Christ, the supreme teacher. These movements reveal an ongoing concern for reform within the church in the years before Luther posted his Ninety-five Theses on the door of All Saints Church, Wittenberg, on October 31, 1517, the eve of All Saint’s Day—the traditional date for the beginning of Reformation.

Martin Luther claimed that what distinguished him from previous reformers was that while they attacked corruption in the life of the church; he went to the theological root of the problem—the perversion of the church’s doctrine of redemption and grace. Luther, pastor and professor at the University of Witenburg, deplored the entanglement of God’s free gift of grace in a complex system of indulgences and good works. In his 95 Theses, he attacked the indulgence system, insisting that that the pope had no authority over purgatory and that the doctrine of the merits of the saints had no foundation in the gospel. Here lay the key to Luther’s concerns for the ethical and theological reform of the church; scripture alone is the authoritive, and justification is by faith, not by works. While he did not intend to break with the Catholic Church, a confrontation with the papacy was not long in coming. In 1521, Luther was tried before the Imperial Diet of Worms and was eventually excommunicated; what began as an internal reform movement had become a fracture in western Christendom.

The Reformation movement within Germany diversified almost immediately, and other reform movements arose independently of Luther. Huldrych Zwingli built a Christian theocracy in Zurich in which church and state joined for the service of God. Zwingli agreed with Luther in the centrality of the doctrine of justification by faith, but he espouse a much more radical understanding of the Eucharist. Luther had rejected the Catholic churches doctrine of transubstantiation, according to which the bread and wine in the Eucharist became the actual body and blood of Christ. According to Luther’s doctrine of consubstantiation, the body of Christ was physically present in the elements because Christ is present everywhere, but Luther was not willing to go as far as Zwingli, who claimed that the Eucharist was simply a memorial of the death of Christ and a declaration of faith by the recipients.

From the group surrounding Zwingli emerged those more radical then himself. These Radical Reformers, part of the so-called left wing of the Reformation, insisted that the principle of scriptural authority be applied without compromise. Unwilling to accept what the considered violations of the biblical teachings, the broke with Zwingli over the issue of infant baptism, thereby receiving the nickname “Anabaptistis” on the grounds that they rebaptized adults who had been baptized as children. The Swiss Anabaptist sought to follow the example of Jesus found in the gospels. The refused to seat oaths or bear arms, taught the strict separations of church and state, and insisted on the visible church of adult believers—distinguished from the world by its disciplined, regenerated life.

Another important form of Protestantism (as those protesting against Rome were designated by the Diet of Speyer in 1529) is Calvinism, named for John Calvin, a French lawyer who fled France after his conversion to the Protestant cause. In Basel, Calvin brought out the first edition, of his Institutes of the Christian Religion in 1536, the first extensive, systematic, theological treatise of the new reform movement. Calvin agreed with Luther’s teaching on justification by faith. However, he found a more positive place for the law within the Christian community than Luther did in his concern to distinguish sharply between law and gospel. In Geneva, Calvin was able to experiment with his ideal of a disciplined community of the elect. Under Calvin’s forceful leadership, church and state were united for the “glory of God.”

The Reformation spread to other European countries over the course of the 16th century. By mid-century, Lutheranism dominated Northern Europe. Eastern Europe offered a seedbed for even more radical varieties of Protestantism, because kings were weak, nobles strong, and cities few, and because religious pluralism had long existed. Spain and Italy were to be the great centres of the Counter-Reformation and Protestantism never gained a strong foothold there.

In England the Reformations roots were primarily political rather than religious. Henry the VIII, incensed by Pope Clement VII’s refusal to grant him a divorce, repudiated papal authority and in 1534 established the Anglican Church with the king, as it’s supreme head. In spite of its political implications, Henry’s reorganization of the church permitted the beginning of religious reform in England, which included the preparation of a liturgy in English, The Book of Common Prayer. In Scotland, John Knox, who spent time in Geneva and was greatly influenced by John Calvin, led the establishment of Presbyterianism, which made possible the eventual union of Scotland with England.

HP94 – Vannevar Bush


This request is from David Potesta way back in July 2005. You may remember some of David’s other requests, such as Bobby Fischer, episode 29 and John Hanson, episode 11.

Vannevar Bush

Born: March 11, 1890

Died: June 28, 1974

US government official and electrical engineer who developed the differential analyzer, the first electronic analogue computer.

Bush was born on March 11, 1890, in Chelsea, Massachusetts. He had two sisters. His father was a Universalist minister.

What is Universalism?

In Christianity, Universalism, Universal reconciliation, or universal salvation, is the doctrine that all people will eventually be saved and go to heaven at some point after they are dead. This is based on the belief that a loving God would not submit any person, regardless of their sins, to everlasting torment, but would instead reform them.

As a child, Bush was sickly and was occasionally bedridden for long stretches of time. Still, he was self-confident and sometimes got into fights with other boys. He once said, “all of [my] recent ancestors [before my father] were sea captains, and they have a way of running things without any doubt. So it may have been partly that, and partly my association with my grandfather, who was a whaling skipper. That left me with some inclination to run a show once I was in it.” (Zachary, 23).

Bush did well in school where he showed an aptitude for math. When he graduated he went off to Tufts College to study engineering. Half of his expenses were paid by a scholarship. He worked as a tutor and aid in the math department to pay the other half. Bush studied earnestly and earned a master’s degree in the time it usually takes to earn a bachelor’s degree. His academic success fueled his desire to do things his way not depending on others’ rules. This trait would become increasingly evident later in his life.

While at Tufts Bush enjoyed his first experience as an inventor. His invention was a land surveying device he called the profile tracer. It looked something like a lawnmower. As it was pushed over land it automatically calculated elevations and drew a crude map. It allowed one man to do the work usually done by three. Bush thought it would be commercially successful, but it never caught on. He learned from this failure. He learned that to become a real engineer he needed to learn more than math and physics. He needed to learn how to effectively deal with people.

After graduation from Tufts, Bush went to work for General Electric testing electrical equipment. He was laid off after a fire broke out in his plant.

Bush taught at Tufts University, Medford, Massachusetts, from 1914 to 1917. After conducting submarine-detection research for the US Navy, he joined the facility for the Massachusetts Institute of Technology (MIT) at Cambridge in 1919. In the late 1920s he devised the network analyzer to simulate the performance of large electrical networks. In 1930 he worked with a team at MIT to build the differential analyzer for solving differential equations. The finished machine, which could handle up to 18 independent variables, foreshadowed the electric computers developed after World War II. Bush’s other developments included the Rapid Selector, a device using a code and microfilm to facilitate information retrieval.

In 1940 Bush was appointed chairman of the National Defense Research Committee. The following year he became director of the newly established Office of Scientific Research and Development (OSRD), which coordinated the nation’s weapons-development research for World War II and advised the government on scientific research and development. Many useful innovations resulted from OSRD research and development including improvements in radar, the proximity fuse, anti-submarine tactics, and various secret devices for the OSS (the precursor of the CIA). Bush was also very closely involved in the Manhattan Project, which developed the first atomic bomb. After the war he served as chairman of the Joint Research and Development Board and was a member of the Research and Development Board of the National Military Establishment. Bush also served as president of the Carnegie Institution from 1939 to 1955.

In the article “As We May Think”, published in Atlantic Monthly in 1945, he described a theoretical machine called a “memex.” It was an obvious extension of Bush’s earlier work with the rapid selector. The memex was also to be a storage and retrieval device using microfilm. It would consist of a desk with viewing screens, a keyboard, selection buttons and levers, and microfilm storage. Information stored on the microfilm could be retrieved rapidly and projected on a screen. The machine was to extend the powers of human memory and association. Just as the human mind forms memories through associations, the user of the memex would be able to make links between documents. Bush called these associative trails. Sound familiar?

This system is remarkably similar to modern hypertext. In fact, Ted Nelson, who coined the term “hypertext” in the 1960’s, acknowledges his debt to Bush.

Vannevar Bush died on June 30, 1974, years before the Internet became widely popular or the World Wide Web even existed. With the growing popularity of the Internet many now look back through its history and see Bush as a visionary.
