Rudolph Goclenius the Elder (Latin: Rudolphus Goclenius; born Rudolf Gockel or Göckel; 1 March 1547 – 8 June 1628) was a German scholastic philosopher. He is sometimes credited with coining the term psychology in 1590, though the term had been used by Pier Nicola Castellani and Gerhard Synellius 65 years earlier.
Goclenius was born in the town of Korbach, located in Waldeck (present-day Waldeck-Frankenberg, Hesse).
He studied at the University of Erfurt, the University of Marburg and the University of Wittenberg, earning his M.A. in 1571. While at Wittenberg, Goclenius published his first book, a collection of short poems. In 1573, he returned to Korbach to direct the local gymnasium, and two years later, he took up the same role in Kassel (Michaelmas 1575). Prior to his appointment in Korbach, he had written to the town’s consuls, Antonius Leusmann and Johannes von Ditmarkhausen, urging the restoration of the school, emphasizing the importance of philosophical education, and requesting financial support due to personal hardship. During that period, he also responded to unusual natural phenomena: Jeremias Nicolai, a student at Korbach Stadtschule from Autumn 1574 onwards, brother of Philipp Nicolai, reported that Goclenius "promptly" composed a poem about "fiery air phenomena" (feurige Lufterscheinungen) observed in the city on November 14, 1574. It was published in Marburg later that year. City historian Wolfgang Medding has suggested that this poem was inspired by an aurora, a hypothesis supported by historical records of auroral observations. The atmospheric phenomena Goclenius first addressed poetically in 1574 reappeared in scholarly form three decades later, when he treated auroras ("chasmata") in his Mirror of Complete Physics (1604).
In 1581, Landgrave Wilhelm IV of Hesse-Kassel, himself a distinguished astronomer, denied Goclenius’s request to return to his hometown of Korbach but instead granted him a professorship at the University of Marburg. Goclenius was officially appointed on September 9 of that year and began his academic career by addressing his colleagues on the subject of physics. He delivered three hours of lectures daily: one for the general public (pro lectione publica), one for master's students (pro magistrandis), and one for bachelor's students (pro baccalaureandis). Over time, he held chairs in physics, logic, mathematics, and ethics, though the precise date of his appointment to the logic professorship remains uncertain, as noted by historian Franz Gundlach. As of December 18, 1589, Goclenius was still serving as Professor of Physics, a role in which he conferred the title of Magister upon thirty students. His transition to the logic chair is suggested by the preface dated January 13, 1590, to his Three Books of Philosophical Debates, on Certain Logical and Physical Questions, published in Marburg that same year. He began teaching mathematics intermittently from 1598, and on May 9, 1603, he succeeded Petrus Nigidius the Younger in the ethics professorship, adding it to his existing role in logic.
Goclenius was frequently consulted for his learned judgment on a variety of matters. In a letter to Otto Melander (dated July 4, 1597), he recounts having been commissioned by Wilhelm IV, Landgrave of Hesse-Kassel—through his Chancellor—to investigate the physical causes of witches floating, a task that led him to compose a speech on the subject. In the same letter, Goclenius expressed his approval of Melander’s work refuting the practice of witch purgation by cold water. On the occasion of student performances of Friedrich Dedekind’s The Christian Knight in February 1604 at the Katharineum in Braunschweig, Goclenius responded to a question posed by Rector Johannes Bechmann: “Whether comedies and tragedies are permissible in a well-ordered state.” He argued affirmatively that such plays, when performed with pious intent, contribute significantly to students’ intellectual and ethical development.
In 1618, Wilhelm's son Moritz appointed Goclenius as one of four delegates to represent Hesse-Kassel at the Synod of Dort, alongside Georg Cruciger, Paul Steinius, and Daniel Angelocrator. His instructions, dated October 1, 1618, outlined the approach and guidelines for conducting the delegates’ business. Moritz decreed that Steinius would serve as the leading delegate with voting rights. Although Goclenius was initially designated as an extraordinary delegate—“not indeed to sit, but only to listen, and to be consulted privately if necessary”—he was nonetheless granted the opportunity to address the assembly formally. In the sixty-seventh session, held on January 25, 1619, he delivered a speech in which he “thoroughly refuted the principal syllogism of the Remonstrants, which was derived from the execution of predestination, using logical principles.”
In his later years, Goclenius faced profound personal and institutional upheaval. The death of his son, Rudolph Goclenius the Younger, in 1621 deeply affected him, both emotionally and professionally. Following the Aulic Council’s judgment of 1623, which resolved the Marburg inheritance dispute in favor of Louis V, Landgrave of Hesse-Darmstadt, Goclenius was among the professors retained at the University of Marburg. On March 27, 1624, he formally swore allegiance to Louis V, thereby securing his continued position at the university. Correspondence from this period—particularly letters addressed to Johann Peter Lotichius—reveal Goclenius’s personal reflections on the political and academic turmoil of the time. The letters also reveal his declining health and literary output, alongside continued admiration for Lotichius’s scholarly achievements.
Recognizing Goclenius’s advanced age, George II, Landgrave of Hesse-Darmstadt, granted him retirement in 1627. George II directed the professors to nominate suitable successors for the chairs of Logic and Rhetoric. Responding to this directive, the faculty convened and, on June 20, 1627, recommended Reverend Konrad Greber for the extraordinary professorship of Logic and Dr. Theodor Höpingk for the professorship of Rhetoric. Although officially retired, Goclenius remained active in academic life and continued to participate in examinations throughout the following year. The final exam, however—held just one day before his death—took place in his absence. On the morning of Trinity Sunday, on June 8, 1628, as Goclenius was preparing to go to church, he suffered a stroke and died. The previous day, he had dinner with Hermann Vultejus and his son-in-law Christoph Deichmann, Chancellor of Lippe. Vultejus recalled, that Goclenius was mentally sharp and articulate, just as he had been in his younger days. After his burial, which took place two days later, Wolfgang Riemenschneider (Loriseca) delivered a speech praising Goclenius as "leader of today's philosophers, Marburgian Plato, European light, Hessian immortal glory". Paul Freher, in Theatrum virorum eruditione clarorum (1688), noted that Goclenius, “besides those to whom he granted the first degree in philosophy over a span of 35 years, personally conferred the honors of Master upon more than 600 individuals.”
Johann Balthasar Schupp, once Goclenius's pupil, satirically recounted that his teacher had declared the 1598 work Analecta, published in Lich, to be the best book he had ever written. The anecdote appears in Schupp’s Ambassadeur Zipphusius, a satirical allegory in which Zipphusius—a fictional schoolmaster from Mount Parnassus, the mythical seat of the Muses and a symbol of intellectual and artistic excellence—is dispatched to the princes and estates of the Holy Roman Empire with a critique of the educational system.
Before enrolling at Wittenberg on July 31, 1570, to pursue his master’s degree, Goclenius married his first wife, Margarethe. Abraham Saur, a jurist in Marburg, recorded the following in his chronicle for April 10:
M. Rudolphus Goclerius [sic] holds wedding. On this day / in the year of Christ 1570 as the Sun entered the Sign of Taurus / of which Astrologers say / it is auspicious for marriage / M. Rudolphus Goclerius [sic] / a young learned Man and Poet / celebrated his wedding in Korbach.
