No. 4."Ernest Renan (1823-1892) was a French philologist, philosopher and historian. His father died when he was aged five, and his mother wanted him to become a priest. Until he was about 16 years old, he was trained by the Church, but due to his investigative and truth-seeking nature as well as his studies (e.g. Hebrew), he was in doubt as to the historical truth of the Scriptures, and with the help of his sister he chose his own path in life. "He studied intensively the languages of the Bible and filled a number of minor academic positions, frequently encountering difficulties because of the heterodoxy and outspokenness of his religious opinions." (Printing and the Mind of Man 352). In 1840 he began studying philosophy and later philology, in 1847 he took his degree as Agrégé de Philosophie and became master at the Lycée of Vendome. After having returned from a mission to Italy in the year 1850 where he gathered material for his historical-philosophical masterpiece, "Averroës et l'Averroisme", he was offered employment at the "Bibliothèque Nationale" (at the manuscript department). In 1861 he was chosen to become professor of Hebrew at the Collège de France, but because the emperor refused to ratify the appointment (inspired by the Clerical party), he was not established in the chair untill 1870. In 1878 he was elected for the Academy. Renan is considered a scolar of the greatest excellence and an impressive writer. Renan's closest confidante was his sister, Henriette, who helped him quit the clerical carrier. They helped eachother financially, travelled together (e.g. on archaeological expeditions) and lived together for many years of their lives. His widely famous work, "Vie de Jésus" is dedicated to her, and their correspondence is very interesting and catching.

(16), 910 pp. A fine copy of the first edition of Moller’s commentaries on the psamls of David, published the same year as he was awarded the rectorship in the Wittenberg Academy. After initially receiving school education in his birthplace, he enrolled at the University of Wittenberg on June 14, 1546. He came into contact with Philipp Melanchthon, who primarily guided him in his preferred studies of oriental languages. The following year he enrolled at the University of Rostock. Back in Wittenberg, he acquired the academic degree of Master of Philosophy on February 24, 1551 and was accepted into the teaching staff of the philosophical faculty on July 7, 1554. At Melanchthon's efforts, after Paul Eber resigned from his professorship of Hebrew at the philosophy faculty, Moller received the position of professor of the Hebrew language at the University of Wittenberg. At the philosophical faculty he took over the deanship in 1562 and held the rectorship of the academy in 1573 and the equivalent vice-rectorate in 1565. He also became an assessor at the Wittenberg consistory in 1573. Moller was drawn to theological studies; he was listed as a theologian as early as 1561 and read about the minor prophets from the original text of the Bible. When in 1574 at the state parliament convened in Torgau the disputes between Philippists and Gnesiolutherans were decided in favor of the latter through the Torgau Articles, Moller and other Philippists refused to sign. He was then imprisoned in Wittenberg, Torgau and Leipzig and finally expelled from Electoral Saxony. On August 8, 1574, he returned to Hamburg and pursued both theological and medical studies. This enabled him to work as a doctor, which he continued until his death from a stroke. Not in Adams.

Berlin, G. reimer, 1842. 4to. No wrappers. In: Crelle's "Journal für die reine und angewandte Mathematik.", 24. Band, zweites Heft., Titlepage to Zweites Heft and pp. 93-188 and 3 plates. Lobatschewsky's paper pp. 164-170. First edition and THE FIRST PRINTING of any part of Lobatschefskij's FIRST MAJOR work on geometry, as it is his own translation of the last to chapters of his "Geometriya" from 1823, a work which was never published in his lifetime. In its original form the "Geometriya" was published in 1909. - The geometrical studies which it contains, led Lobatschewski to his main discovery, the Non-Euclidean Geometry , published in Russian in Kazan 1829, and in it he developes the idea of geometry independent of the fifth postulate. The last two chapters of the unpublished work is offered here, and the chapters deals with the solution of triangles, on given measurements, and on probable errors in calculation, deaply connected to his attempts to establish experimentally what sort of geometry obtains in the real world. - "The period 1835 to 1838 saw him concerned with writing "Novye nachalaa geometrii s polnoi teoriei parallellnykh" (New Principles of Geometry with a Complete Theory of Parallels), which incorporated a version of his first work,the still unpublished "Geometriya". The last two chapters of the book were abbriviated and translated for publication in Crelle's Journal in 1842." (DSB)."Lobachevsky was interested in the theory of parallels from at least 1815. Lecture notes of the period 1815-17 are ectant, in which Lobachevsky attempts various waus to establish the Euclidean theory. he proves Legendre's two propositions, and employs also the ideas of direction and infinite areas. In 1823 he prepared a treatise on geometry for use at the university, but it obtained so unfavourable a report that it was not printed. The MS. remained buried in the University archives until it was discovered and printed in 1909. In this book he states that "a rigorous proof of the postulate of Euclid has nit hitherto been discovered; those which have been given may be called explanations, and do not deserve to be considered as mathematical proofs in the full sense."(Sommerville: The Elements of Non-Euclidean geometry. 1914).

(6), VIII, 417, (1) pp. Scarce first edition of the work in which a welfare principle is presented for the first time, laying the groundwork for the welfare state as we know it today. Høffding’s “Ethics” came to have a profound impact upon European politics and philosophical ethics of the Positivist era and directly influenced the development of the Scandinavian welfare state. “[I]t was Høffding who was the first in the world to work out a welfare-principle, namely in his “Etik” (Ethics) in 1887. Today, Høffding is not widely known, but in his lifetime and up to the 1950ties he was an internationally famous philosopher, whose works were translated into many languages and who was several times nominated for the Nobel Prize.” (Andersen, A.T.: The Dialogic and Religious Theme of Welfare in Harald Høffding…, p. 104). “Etik” constitutes an ethical system. Høffding discusses the principal questions in order to develop a scientific ethics, or a moral science if one will, analyzes the ethical principles that are expressed in ethical assessments, and on the basis hereof develops an individualistic and a social ethic that was way ahead of its time, but which found great resonance within the reading public. The book had an enormous impact. It appeared five times in Høffding’s life-time, sold extremely well, and was quickly translated into German and French – “Denmark had gotten its first internationally known and acknowledged philosopher, several decades before Kierkegaard had his breakthrough on the international scene.” (Koch, Dansk filosofi i positivisments tidsalder, p. 41 – translated from Danish). “Høffding became a mentor to many – not least because of the humanity that marks this book [i.e. Ethics] and because of the well-balanced treatment it gives of the social and political questions of the time, of the relationship between the sexes and between church and state, just to mention a few of the “important life conditions” it deals with. Students in personal crisis contacted him, and people in difficult circumstances wrote to him for advice. Not least because of his ethical view, he came to appear as the old, wise man of the nation… His influence in the neighboring countries was also great. For instance, his ethical considerations in the years around 1900 came to play a significant role for the young Swedish social democrats and for their conception of a coming welfare state.” (Koch, Dansk filosofi i positivisments tidsalder, p. 60 – translated from Danish). “Harald Høffding, the Danish philosopher and historian of philosophy, was born in Copenhagen and lived there throughout his life. From 1883 to 1915 he was professor of philosophy at the University of Copenhagen. Høffding received a degree in divinity in 1865, but he had already decided not to take orders. A study of Søren Kierkegaard's works, and especially of his views on Christianity, had led to an intense religious crisis ending in a radical break with Christianity. Høffding sought in philosophy a new personal orientation and gradually developed into an extraordinarily many-sided liberal humanist. His philosophical development was influenced during a stay in Paris (1868–1869) by the study of French and English positivism… his activity as a scholar ranged over every branch of philosophy, including psychology. His works display a vast knowledge, a keen eye for essentials, and a critically balanced judgment. They were translated into many languages and widely used as textbooks. By the turn of the twentieth century Høffding's reputation was worldwide and he knew personally many leading thinkers. He was the outstanding Danish philosopher of his day, and in 1914 the Royal Danish Academy of Sciences and Letters assigned him the honorary residence of Gammel Carlsberg, where he lived to the end of his life. The residence later passed to the physicist Niels Bohr, a younger friend of Høffding.” (Frithiof Brandt, Encyclopaedia of Philosophy). “The Danish philosopher Harald Høffding was the first in the world to work out a welfare-principle. He expressed a dialogic and democratic standpoint, a fellowship and an ideal concerning equality, and consequently a distinct philosophical basis for the realization of the formation of the welfare state.” (Andersen, A.T.: The Dialogic and Religious Theme of Welfare in Harald Høffding…, p. (103).).

First printing of a MILESTONE PAPER IN ELECTROCHEMISTRY in which Davy shows that electricity is capable of decomposing the most stable elements."Humphry Davy was one of the most brilliant chemists of the early nineteenth century. His early study of nitrous oxide brought him his first reputation, but his later and most importent investigations were devoted to electrochemistry. Following Galvani's experiments and the discovery of the voltaic pile, interest in galvanic electricity had become widespread. The first electrolysis by means of the pile was carried out in 1800 by Nicholson and Carisle, who obtained oxygen and hydrogen from water. Davy began to examine the chemical effects of electricity in 1800, and his numerous discoveries were presented in his Bakerian lecture to the Royal Society on November 20, 1806 (the paper offered here). His experiments, along the lines stated in this paper, lead to his discoveries of potassum and sodium in 1807 and the year after to barium, calcium and boron.(A Source Book in Chemistry p. 243). - Sparrow: Milestones of Science No 52. - Wheeler Gift: 2511.

(London, Harrison and Sons, 1898). 4to. No wrappers as extracted from "Philosophical Transactions" Year 1897, Volume 190 - Series A. - Pp. 205-300, textillustr. Clean and fine. First appearance of an importent paper announcing the first formulation of the complete Lorentz-transformation and with the first prediction of time dilation. "It seems churlish however to deny that Larmor had gained an importent, if limited insight into time dilation, two years before Lorentz's striking similar and independent insight of 1899."(Harvey R. brown in "Physical relativity", p. 61). - The paper also presents the "Larmor formula".It's notable that Larmor was the first who recognized that some sort of time dilation is a consequence of the Loretz transformation as well, because individual electrons describe corresponding parts of their orbits in times shorter for the [rest] system in the ratio 1/y.Parallel to the development of Lorentz ether theory, Larmor published the complete Lorentz transformations in the Philosophical Transactions of the Royal Society in 1897 (in the paper offered) some two years before Hendrik Lorentz (1899, 1904) and eight years before Albert Einstein (1905). Larmor predicted the phenomenon of time dilation, at least for orbiting electrons, and verified that the FitzGerald-Lorentz contraction (length contraction) should occur for bodies whose atoms were held together by electromagnetic forces. In his book Aether and Matter (1900), he again presented the Lorentz transformations, time dilation and length contraction (treating these as dynamic rather than kinematic effects). Larmor opposed Albert Einstein's theory of relativity (though he supported it for a short time). Larmor rejected both the curvature of space and the special theory of relativity, to the extent that he claimed that an absolute time was essential to astronomy.Larmor held that matter consisted of particles moving in the aether. Larmor believed the source of electric charge was a "particle" (which as early as 1894 he was referring to as the electron). Thus, in what was apparently the first specific prediction of time dilation, he wrote "... individual electrons describe corresponding parts of their orbits in times shorter for the [rest] system in the ratio (1 - v2/c2)1/2" (in the paper offered).

XXX, (2), 336 pp. + (8), 346 pp. + (2), 368 pp. + 372 pp. + XXVI, 352 pp. + 324 pp. Rare first edition of the first Danish translation of Rousseau's monumental work (Emilius, or an Essay on Education), being one of the absolutely most important and influential works on education. Virtually no work has had as great an impact on paedagogics as this one. Being one of the most influential thinkers of the 18th century, Rousseau is considered one of the indirect causes of the French Revolution. In Rousseau one certainly finds one of the most influential spokesmen for 18th century thought, and it is primarily the thoughts of him and Voltaire that are put into action with the Revolution. Not only in France can the effects of his philosophy and thoughts on upbringing and education be clearly seen; -his ideas were of decisive character to the generation of artists, writers, poets, philosophers etc. in the beginning to middle of the 19th century, which seminally affects Danish thought, as it is in this period that our most important and famous cultural personas are being influenced (e.g. H.C. Andersen and Søren Kierkegaard); thus this first Danish translation is of great importance and interest. In Danish literature there is talk about the Rousseauan spirit, and it is in this spirit that the entire literary production of H.C. Andersen can be viewed, -directly or indirectly. Rousseau's three main thoughts in Émile - on the childlike, on the natural and on simple religious faith - fits like a glove on the main messages and morals of H.C. Andersen's works.Søren Kierkegaard is known to have owned a copy of Rousseau's Émile in French as well as a copy of this first Danish translation (see "Auktionsprotokol over Søren Kierkegaards Bogsamling" no. 941-43). As opposed to H.C.A., though, the philosophy and educational program of Rousseau does not correspond with the Christianity of Kierkegaard, who, however, quotes and comments on Rousseau and his writings on several occasions in his diaries.In Émile, Rousseau poses an entirely new approach to education and the upbringing of children. His thoughts were exceedingly controversial, the work was burnt by the executioner immediately after its first appearance and Rousseau had to flee the country due to a warrant for his arrest. There is no need to say that these new thoughts were also widely influential on Danish thought, and this especially after the appearance of the Danish translation (34-37 years after the French original). Not only Kierkegaard and H.C.A. were influenced by this great thinker, so were the likes of Ingemann, one of our greatest poets."The first and last of these (i.e. Héloise and Émile), with their sentimental expression of deism, gave much offence, and Rousseau, like Voltaire, was forced to flee to Prussia. Restless and locally unpopular, he fled again to England, where he had a great welcome. Hume, who had offered him asylum, looked after him patiently..." (PMM 207, Printing and the Mind of Man).

Reval, Kluge, 1872. 8vo. Completely uncut and unopened in the original printed orange wrappers. A bit of soiling to wrappers, minor lacks to capitals, a small tear to the spine and a tear to the back wrapper - no loss. (10), 405, (1) pp. Uncommon first edition of Dellingshausen's noteworthy main work, which constitutes one of the first attempts to prove the identity of particles and waves, thus anticipating by many decades a theory that eventually led to the creation of wave-mechanics, by many considered the single most important contribution to theoretical physics in the twentieth century.The honour of founding wave-mechanics befalls Louis de Broglie, who won the Nobel Prize for it in 1929. With his PhD-thesis of 1924, which inspired Einstein, who supported his theory of the wave-particle duality of matter, De Broglie had set the basis for one of the greatest innovations of the 20th century. It is, however, often forgotten - or not known - that a few solid minds had actually had theories along the same lines, long before de Broglie writes his seminal PhD-thesis. The first and most well-founded of these seems to be Dellingshausen, who presents his theory in full in his great main work "Grundzüge einer Vibrationstheorie der Natur". "Before we analyze Louis de Broglie's decisive contributions to the conceptual development of quantum mechanics and, in particular, his introduction of what is often called "matter waves", we shall ask ourselves whether - as it has so often occurred with great innovations in science - his ideas had not been anticipated, at least in part, by speculative thinkers in the past. Because of his optical-mechanical analogy Hamilton is often regarded as a direct precursor of de Broglie's hypothesis. This, however, is only partially true [...] Hamilton's interest, it is clear, lay wholly in the formal-mathematical aspects and not in the problem of the physical nature of light.There were in the nineteenth century, however, some unorthodox thinkers who maintained, whether on physical or philosophical grounds, the ultimate identity between particles and waves. One of the most eloquent proponents of these ideas was Baron Nicolai Dellingshausen. After studying physics at the University of Dorpat, Leipzig, and Heidelberg, he returned to his Baltic estate and wrote a number of interesting studies on physics while administering his lands and farms. His major work, an enlarged version of an earlier essay, was published in 1872 under the title "Grundzüge einer Vibrationstheorie der Natur". Basing his ideas on the cartesian conception of extension as the chief characteristic of matter and on the kinetic theory of heat which reduced heat to motion, Dellingshausen identified atoms with standing waves and interpreted motion of particles as a vibrational process. According to his doctrine bodies are merely "Extended centers of vibrational motions" and the "nature of matter is extension in motion." (Jammer, pp. 239-40).

First European publication of this classic paper which announced one of the most celebrated experiments in the history of physics and eventually led Einstein to his Relativity Theory (see PMM 378,410,408). The paper appeared first in the "American Journal of Science" just one month before in November, not in August as stated in PMM. The offered paper appeared in the December issue 1887 and in a slightly modified form.Michelson was the first American to be awarded the Nobel Prize for Physics, in 1907, for the measurement of the speed of light through the design and application of precise optical instruments such as the interferometer, which was used in this experiment."Michelson, trained at the U.S. Naval Academy, and Morley, minister turned chemist, began a series of experiments to determine the relation of ether drift and the velocity of light, effects of extremely minute values. They used a slightly silvered glass set angular to a ray of sunlight so that a part ofthe ray was transmitted, a part reflected out and again returned, thereby providing two paths, one perpendicular to the other. If drift existed, the superimposed rays would produce interference. None was observed, showing that the earth's motion did not affect the light's speed. The negative result held revolutionary implications which led directly thru Lorentz and Einstein to the acceptance of new standards of reference of time and space from geometry and cosmometry."(Dibner).Dibner No 161 (listing the offered paper from Philosophical Magazine). - Norman 1505.- Magee "A Source Book in Physics", pp. 369 ff.
