The Scientific Revolution and the Emergence of Modern Science
Background to the Scientific Revolution
Late Medieval scholastic philosophers had advanced mathematical and physical thinking in many ways
The subjection of these thinkers to a strict theological framework and their unquestioning reliance on a few ancient authorities, especially Aristotle & Galen, limited where they could go
Medieval scholars made use of Latin translations of Aristotle, Galen & Ptolemy to develop many of their positions in the fields of physics, medicine, & astronomy
Renaissance scientist mastered Greek which exposed them to different works by past masters
Copernicus, founder of heliocentrism, found that Philolaus and a number of ancients believed that the earth moved not the sun
Renaissance artists desire to imitate nature led them to rely upon a close observation of nature which in turn impacted scientific study
The 15th & 16th centuries witnessed a proliferation of books dedicated to machines & technology which espoused the belief that innovation in techniques was necessary
The Scientific Revolution of the 17th Century was based upon the intellectual and scientific accomplishments of previous centuries
The origins of the Scientific Revolution can be traced to the work of a very small number of great European intellectuals
According to Da Vinci mathematics was the key to understanding the nature of things
Scholars devoted to Hermeticism believed in seeing the world as a living embodiment of divinity where humans could use mathematics and magic to dominate nature
Possible influences and causes of the Scientific Revolution include: mathematical and naturalistic skills of Renaissance artists, the humanists rediscovery of Greek mathematicians and thinkers, and the Hermetic belief in magic and alchemy
Toward a New Heaven: A Revolution in Astronomy
The greatest achievements in science during the 16th and 17th Centuries came in astronomy, mechanics, and medicine
The Ptolemaic conception of the universe was also known as the geocentric conception
Nicholaus Copernicus (1473-1543)
The general conception of the universe before Copernicus was that the earth was the stationary center and heavenly spheres orbited it
Born in Poland
Received a doctorate in canon law and studied in both Poland and Italy
Focus was on mathematics and astronomy
Published On the Revolutions of the Heavenly Spheres in 1543 which attacked the Ptolemaic concept of an earth-centered universe
Ideas of Copernicus were nearly as complicated as Ptolemy’s
using elaborate astronomical and mathematical calculations Copernicus argued that the universe consisted of eight spheres with the sun motionless in the center
Planets revolved around sun and moon revolved around earth
Ideas immediately condemned, especially by Protestant leaders like Luther who condemned the discovery as contrary to their notions of creation
Tycho Brahe (1546-1601)
Danish nobleman
Outfitted castle with a library , observatory, and instruments to more accurately observe astronomical sites. (Uraniborg)
Johannes Kepler (1571-1630)
Germany’s best-known astronomer
Used data to derive laws of planetary motion that confirmed Copernicus’s heliocentric theory but that showed the orbits were elliptical
Friend of Galileo and members together of a new European scientific community maintaining contact through letters and new publications
Ideas gained acceptance despite disproving the great Aristotle’s conviction that the motion of planets was steady and unchanging
Galileo Galilei (1564-1642)
Came from a lesser Pisan noble family (Italian)
Abandoned medicine for his true love, mathematics
Taught mathematics at prestigious university at Padua
Was first European to make systematic observations of the heavens by means of a telescope
Through his observations, he concluded that planets were not made of some perfect substance but had natural properties similar to earth
Galileo’s The Starry Messenger (1610) probably did more to make Europeans aware of the new picture of the universe than the mathematical theories of Copernicus or Kepler
In The Starry Messenger, Galileo had revealed himself as a firm proponent of Copernicus’s heliocentric system (encouraged by Jesuits and Dominicans ~ Church condemned him)
The Catholic Roman Inquisition attacked Galileo for his scientific ideas with encouragement of the Dominican and Jesuits orders of the church pledged to defend ancient Aristotelian ideas and Catholic orthodoxy
Unphased by condemnation, Galileo published his most famous work, Dialogue on the Two Chief World Systems: Ptolemaic andCorpernican (1632)~ written in Italian for greater effect
Dialogue displayed further support for ideas of Copernicus
Catholic Church’s Roman Inquisition ordered him to recant in a public trial and humiliation
Spent last eight years of his life under house arrest in Florence where he studied the principle of motion
Stressed principle of inertia
If a uniform force were applied to an object, it would move at an accelerated speed rather than a constant speed
Condemnation of Galileo by the Inquisition seriously hampered further scientific work in Italy
Isaac Newton (1642-1727)
Born in little English village of Woolsthorpe
studied mathematics at Cambridge
from 1684 to 1686, he wrote Mathematical Principles of Natural Philosophy (aka Principia) which demonstrated through his rules of reasoning that the universe was a regulated machine operating according to universal laws [Written in LATIN—one of the last major European works to be written in Latin]
although a great scientist, he was also intensely interested in the OCCULT; considered himself a representative of the Hermetic tradition
Newton’s mathematical discoveries included the calculus, a mathematical means of measuring rates of change
Newton defined the basic concepts of mechanics by elaborating on the laws of motion:
every object continues in a state of rest or uniform motion in a straight line unless deflected by a force
the rate of change of motion of an object is proportional to the force acting upon it
to every action there is always an equal and opposite reaction
Newton’s universal law of gravity proved that through its mathematical proof it could explain all motion in the universe
Newton’s ideas were readily accepted in England, but it took much of the 18th Century before his ideas were accepted on the rest of the continent
only English scientist buried at Westminster Abbey
Advances in Medicine
Medicine also experienced a transformation during this era
Galen’s influence on the medieval medical world was pervasive in anatomy, physiology, and disease
Treatment of disease was highly influenced by Galen’s doctrine of four bodily humors: blood, yellow bile, phlegm, black bile
Three figures are associated with changes in medicine in the 16th and 17th Centuries:
1. Paracelsus (1493-1541)
born Philippus Aureolus von Hohenheim in Switzerland
associated with the diagnosis and treatment of diseases
revolutionized medicine by advocating the chemical philosophy of medicine
Andreas Vesalius (1514-1564)
best known for his book On the Fabric of the Human Body (1543)
presented a careful examination of the individual organs and the general structure of the human body
his hands-on approach advocated in book helped overthrow some of Galen’s most glaring errors
b. still clung to some of Galen’s incorrect ideas on blood flow
3. William Harvey (1578-1657)
English scientist who studied at Cambridge and at Padua
His book, On the Motion of the Heart and Blood (1628) demolished Galen’s idea that the liver was the beginning point of blood circulation
Harvey’s theory of the circulation of the blood laid the foundation for modern physiology
Women in the Origins of Modern Science
During the Middle Ages, except for members of religious orders, women who sought a life of learning were severely hampered by the traditional attitude that a woman’s proper role was as a daughter, wife, and mother
During the 14th and 15th centuries learned men began encouraging women to read and study classical Christian texts
In a similar way to how women were drawn to humanism, women were drawn to the Scientific Revolution
Opportunities for women as well as alternatives to formal humanistic education could often be found in aristocratic and princely courts and in artisan workshops
Most women involved in the Scientific Revolution were from the aristocracy
Examples of women taking part in the Scientific Revolution include:
Margaret Cavendish (1623-1673)
Duchess of Newcastle (English)
Participated in her day’s scientific debates
Wrote Observations upon Experimental Philosophy and Grounds of Natural Philosophy
Attacked the belief that humans through science were masters of nature
Due to gender, she was excluded from membership in the Royal Society
Maria Sibylla Merian (1647-1717)
accomplished entomologist
wrote Wonderful Metamorphosis and Special Nourishment of Caterpillars
major work was Metamorphosis of the Insects of Suriname
Maria Winkelmann (1670-1720)
famous German astronomer
married the leading German astronomer of the time, Gottfried Kirch
became husband’s assistant at Berlin’s Academy of Science observatory
denied official post at Berlin Academy because of gender/lack of degree
The overall effect of the Scientific Revolution on the argument about women was to generate facts about differences between men and women that were used to prove male dominance (EX: Spinoza—thought women were “naturally” inferior)
Toward a New Earth: Descartes, Rationalism, and a New View of Humankind
Rene Descartes (1596-1650)
born into a family of lower French nobility
considered the father of modern rationalism
wrote Discourse on Method (1637) that expounded his theories about the universe
his philosophy stressed a separation of mind and matter
believed that the world could be understood by the same principles inherent in mathematical thinking
books were placed on the Papal Index of Forbidden Books lists and were condemned by many Protestant religious leaders
Scientific Method
The development of a scientific method was crucial to the evolution of science in the modern world
Francis Bacon (1561-1626)
Englishman with few scientific credentials
important to the Scientific Revolution for his emphasis on empirical, experimental observation
most important work was the unfinished The Great Instauration
Believed that carefully organized experiments and thorough, systematic observations, led to correct generalizations being developed
the scientific method was valuable in answering the question “how” something works, and its success in doing this gave others much confidence in the method
Science and Religion in the 17th Century
Organized religions in the 17th Century rejected scientific discoveries that conflicted with the Christian view of the world
Benedict de Spinoza (1632-1677)
Dutch philosopher who grew up in Amsterdam
excommunicated by his Dutch synagogue and ostracized by major Dutch churches
Spinoza was fiercely independent, refusing an appointment to the University of Heidelberg for fear of having to sacrifice some of his views
was influenced by Descartes, but saw no separation between mind and matter
believed women were “naturally” inferior to men
believed the failure to understand God led to people using nature for their own self-interest
brilliant mathematician and accomplished scientist
French scientist who sought to keep science and religion united
invented a calculating machine
major work was Pensees (Thoughts)
in Pensees, he attempted to convince rationalists that Christianity was valid by appealing to their reason and emotions
believed humans could not understand infinity, only God could
failed in his goal to unite Christianity and science
The Spread of Scientific Knowledge
The first of the scientific societies appeared in Italy
Concerning the first important scientific societies, the French Academy differed from the English Royal Society in the former’s government support and control
During the 17th Century, royal and princely patronage of science became an international phenomenon
The scientific societies of early modern Europe established the first scientific journals appearing regularly
Science became an integral part of Western culture in the 18th Century because it offered a new means to make profits and maintain social order
