Isaac Newton: First

Preface (8 May 1686)
Philosophiae Naturalis Principia Mathematica (1687)
Context: The ancients considered mechanics in a twofold respect; as rational, which proceeds accurately by demonstration, and practical. To practical mechanics all the manual arts belong, from which mechanics took its name. But as artificers do not work with perfect accuracy, it comes to pass that mechanics is so distinguished from geometry, that what is perfectly accurate is called geometrical; what is less so is called mechanical. But the errors are not in the art, but in the artificers. He that works with less accuracy is an imperfect mechanic: and if any could work with perfect accuracy, he would be the most perfect mechanic of all; for the description of right lines and circles, upon which geometry is founded, belongs to mechanics. Geometry does not teach us to draw these lines, but requires them to be drawn; for it requires that the learner should first be taught to describe these accurately, before he enters upon geometry; then it shows how by these operations problems may be solved.

Query 28 : Are not all Hypotheses erroneous in which Light is supposed to consist of Pression or Motion propagated through a fluid medium?
Opticks (1704)
Context: To make way for the regular and lasting Motions of the Planets and Comets, it's necessary to empty the Heavens of all Matter, except perhaps some very thin Vapours, Steams or Effluvia, arising from the Atmospheres of the Earth, Planets and Comets, and from such an exceedingly rare Æthereal Medium … A dense Fluid can be of no use for explaining the Phænomena of Nature, the Motions of the Planets and Comets being better explain'd without it. It serves only to disturb and retard the Motions of those great Bodies, and make the frame of Nature languish: And in the Pores of Bodies, it serves only to stop the vibrating Motions of their Parts, wherein their Heat and Activity consists. And as it is of no use, and hinders the Operations of Nature, and makes her languish, so there is no evidence for its Existence, and therefore it ought to be rejected. And if it be rejected, the Hypotheses that Light consists in Pression or Motion propagated through such a Medium, are rejected with it.
And for rejecting such a Medium, we have the authority of those the oldest and most celebrated philosophers of ancient Greece and Phoenicia, who made a vacuum and atoms and the gravity of atoms the first principles of their philosophy, tacitly attributing Gravity to some other Cause than dense Matter. Later Philosophers banish the Consideration of such a Cause out of natural Philosophy, feigning Hypotheses for explaining all things mechanically, and referring other Causes to Metaphysicks: Whereas the main Business of natural Philosophy is to argue from Phenomena without feigning Hypotheses, and to deduce Causes from Effects, till we come to the very first Cause, which certainly is not mechanical.

Vol. I, Ch. 13: Of the King who did according to his will, and magnified himself above every God, and honored Mahuzzims, and regarded not the desire of women
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: Hitherto the principles of the Encratites had been rejected by the Churches; but now being refined by the Monks, and imposed not upon all men, but only upon those who would voluntarily undertake a monastic life, they began to be admired, and to overflow first the Greek Church, and then the Latin also, like a torrent. Eusebius tells us, that Constantine the great had those men in the highest veneration, who dedicated themselves wholly to the divine philosophy; and that he almost venerated the most holy company of Virgins perpetually devoted to God; being certain that the God to whom he had consecrated himself did dwell in their minds. In his time and that of his sons, this profession of a single life was propagated in Egypt by Antony, and in Syria by Hilarion; and spread so fast, that soon after the time of Julian the Apostate a third part of the Egyptians were got into the deserts of Egypt. They lived first singly in cells, then associated into cœnobia or convents; and at length came into towns, and filled the Churches with Bishops, Presbyters and Deacons. Athanasius in his younger days poured water upon the hands of his master Antony; and finding the Monks faithful to him, made many of them Bishops and Presbyters in Egypt: and these Bishops erected new Monasteries, out of which they chose Presbyters of their own cities, and sent Bishops to others. The like was done in Syria, the superstition being quickly propagated thither out of Egypt by Hilarion a disciple of Antony. Spiridion and Epiphanius of Cyprus, James of Nisibis, Cyril of Jerusalem, Eustathius of Sebastia in Armenia, Eusebius of Emisa, Titus of Bostra, Basilius of Ancyra, Acacius of Cæsarea in Palestine, Elpidius of Laodicea, Melitius and Flavian of Antioch, Theodorus of Tyre, Protogenes of Carrhæ, Acacius of Berrhæa, Theodotus of Hierapolis, Eusebius of Chalcedon, Amphilochius of Iconium, Gregory Nazianzen, Gregory Nyssen, and John Chrysostom of Constantinople, were both Bishops and Monks in the fourth century. Eustathius, Gregory Nazianzen, Gregory Nyssen, Basil, &c. had Monasteries of Clergymen in their cities, out of which Bishops were sent to other cities; who in like manner erected Monasteries there, till the Churches were supplied with Bishops out of these Monasteries.... Not long after even the Emperors commanded the Churches to choose Clergymen out of the Monasteries by this Law.

Vol. I, Ch. 11: Of the Times of the Birth and Passion of Christ
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: John therefore baptized two summers, and Christ preached three. The first summer John preached to make himself known, in order to give testimony to Christ. Then, after Christ came to his baptism and was made known to him, he baptized another summer, to make Christ known by his testimony; and Christ also baptized the same summer, to make himself the more known: and by reason of John's testimony there came more to Christ's baptism than to John's. The winter following John was imprisoned; and now his course being at an end, Christ entered upon his proper office of preaching in the cities. In the beginning of his preaching he completed the number of the twelve Apostles, and instructed them all the first year in order to send them abroad. Before the end of this year, his fame by his preaching and miracles was so far spread abroad, that the Jews at the Passover following consulted how to kill him. In the second year of his preaching, it being no longer safe for him to converse openly in Judea, he sent the twelve to preach in all their cities: and in the end of the year they returned to him, and told him all they had done. All the last year the twelve continued with him to be instructed more perfectly, in order to their preaching to all nations after his death. And upon the news of John's death, being afraid of Herod as well as of the Jews, he walked this year more secretly than before; frequenting deserts, and spending the last half of the year in Judea, without the dominions of Herod.

Vol. I, Ch. 13: Of the King who did according to his will, and magnified himself above every God, and honored Mahuzzims, and regarded not the desire of women
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: Hitherto the principles of the Encratites had been rejected by the Churches; but now being refined by the Monks, and imposed not upon all men, but only upon those who would voluntarily undertake a monastic life, they began to be admired, and to overflow first the Greek Church, and then the Latin also, like a torrent.

Vol. I, Ch. 12: Of the Prophecy of the Scripture of Truth
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: Thus the Empire of the Greeks, which at first brake into four kingdoms, became now reduced into two notable ones, henceforward called by Daniel the kings of the South and North. For Ptolemy now reigned over Egypt, Lybia, Ethiopia, Arabia, Phœnicia, Cœlosyria, and Cyprus; and Seleucus, having united three of the four kingdoms, had a dominion scarce inferior to that of the Persian Empire, conquered by Alexander the great. All which is thus represented by Daniel: And the king of the South [Ptolemy] shall be strong, and one of his Princes [Seleucus, one of Alexander's Princes] shall be strong above him, and have dominion; his dominion shall be a great dominion.

Vol. I, Ch. 14: Of the Mahuzzims, honoured by the King who doth according to his will
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: Gregory Nyssen tells us, that after the persecution of the Emperor Decius, Gregory Bishop of Neocæsarea in Pontus, instituted among all people, as an addition or corollary of devotion towards God, that festival days and assemblies should be celebrated to them who had contended for the faith, that is, to the Martyrs. And he adds this reason for the institution: When he observed, saith Nyssen, that the simple and unskilful multitude, by reason of corporeal delights, remained in the error of idols; that the principal thing might be corrected among them, namely, that instead of their vain worship they might turn their eyes upon God; he permitted that at the memories of the holy Martyrs they might make merry and delight themselves, and be dissolved into joy. The heathens were delighted with the festivals of their Gods, and unwilling to part with those delights; and therefore Gregory, to facilitate their conversion, instituted annual festivals to the Saints and Martyrs. Hence it came to pass, that for exploding the festivals of the heathens, the principal festivals of the Christians succeeded in their room: as the keeping of Christmas with ivy and feasting, and playing and sports, in the room of the Bacchanalia and Saturnalia; the celebrating of May-day with flowers, in the room of the Floralia; and the keeping of festivals to the Virgin Mary, John the Baptist, and divers of the Apostles, in the room of the solemnities at the entrance of the Sun into the signs of the Zodiac in the old Julian Calendar. In the same persecution of Decius, Cyprian ordered the passions of the Martyrs in Africa to be registered, in order to celebrate their memories annually with oblations and sacrifices: and Felix Bishop of Rome, a little after, as Platina relates... "consulting the glory of the Martyrs, ordained that sacrifices should be celebrated annually in their name." By the pleasures of these festivals the Christians increased much in number, and decreased as much in virtue, until they were purged and made white by the persecution of Dioclesian. This was the first step made in the Christian religion towards the veneration of the Martyrs: and tho it did not yet amount to an unlawful worship; yet it disposed the Christians towards such a further veneration of the dead, as in a short time ended in the invocation of Saints.

Vol. I, Ch. 2: Of the Prophetic Language
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: For understanding the Prophecies, we are, in the first place, to acquaint our-selves with the figurative language of the Prophets. This language is taken from the analogy between the world natural, and an empire or kingdom considered as a world politic. Accordingly, the whole world natural consisting of heaven and earth, signifies the whole world politic, consisting of thrones and people, or so much of it as is considered in the Prophecy: and the things in that world signify the analogous things in this. For the heavens, and the things therein, signify thrones and dignities, and those who enjoy them; and the earth, with the things thereon, the inferior people; and the lowest parts of the earth, called Hades or Hell, the lowest or most miserable part of them. Whence ascending towards heaven, and descending to the earth, are put for rising and falling in power and honor: rising out of the earth, or waters, and falling into them, for the rising up to any dignity or dominion, out of the inferior state of the people, or falling down from the same into that inferior state; descending into the lower parts of the earth, for descending to a very low and unhappy estate; speaking with a faint voice out of the dust, for being in a weak and low condition; moving from one place to another, for translation from one office, dignity, or dominion, to another; great earthquakes, and the shaking of heaven and earth, for the shaking of kingdoms, so as to distract or overthrow them; the creating a new heaven and earth, and the passing away of an old one, or the beginning and end of the world, for the rise and ruin of the body politic signified thereby.

Vol. I, Ch. 4: Of the vision of the four Beasts
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: I beheld, saith Daniel, till the Beast was slain, and his body destroyed, and given to the burning flames. As concerning the rest of the Beasts, they had their dominion taken away: yet their lives were prolonged for a season and a time [Chap. vii. 11, 12. ]. And therefore all the four Beasts are still alive, tho the dominion of the three first be taken away. The nations of Chaldea and Assyria are still the first Beast. Those of Media and Persia are still the second Beast. Those of Macedon, Greece and Thrace, Asia minor, Syria and Egypt, are still the third. And those of Europe, on this side Greece, are still the fourth.

Vol. I, Ch. 11: Of the Times of the Birth and Passion of Christ
Observations upon the Prophecies of Daniel, and the Apocalypse of St. John (1733)
Context: The times of the Birth and Passion of Christ, with such like niceties, being not material to religion, were little regarded by the Christians of the first age. They who began first to celebrate them, placed them in the cardinal periods of the year; as the annunciation of the Virgin Mary, on the 25th of March, which when Julius Cæsar corrected the Calendar was the vernal Equinox; the feast of John Baptist on the 24th of June, which was the summer Solstice; the feast of St. Michael on Sept. 29, which was the autumnal Equinox; and the birth of Christ on the winter Solstice, Dec. 25, with the feasts of St. Stephen, St. John and the Innocents, as near it as they could place them. And because the Solstice in time removed from the 25th of December to the 24th, the 23d, the 22d, and so on backwards, hence some in the following centuries placed the birth of Christ on Dec. 23, and at length on Dec. 20: and for the same reason they seem to have set the feast of St. Thomas on Dec. 21, and that of St. Matthew on Sept. 21. So also at the entrance of the Sun into all the signs in the Julian Calendar, they placed the days of other Saints; as the conversion of Paul on Jan. 25, when the Sun entered Aquarius; St. Matthias on Feb. 25, when he entered Pisces; St. Mark on Apr. 25, when he entered Taurus; Corpus Christi on May 26, when he entered Gemini; St. James on July 25, when he entered Cancer; St. Bartholomew on Aug. 24, when he entered Virgo; Simon and Jude on Oct. 28, when he entered Scorpio: and if there were any other remarkable days in the Julian Calendar, they placed the Saints upon them, as St. Barnabas on June 11, where Ovid seems to place the feast of Vesta and Fortuna, and the goddess Matuta; and St. Philip and James on the first of May, a day dedicated both to the Bona Dea, or Magna Mater, and to the goddess Flora, and still celebrated with her rites. All which shews that these days were fixed in the first Christian Calendars by Mathematicians at pleasure, without any ground in tradition; and that the Christians afterwards took up with what they found in the Calendars.
