The history of science is the study of the development of science and scientific knowledge, including both thenatural sciences and social sciences. (The history of the arts and humanities is termed as the history of scholarship.) Science is a body of empirical, theoretical, and practical knowledge about the natural world, produced by scientists who emphasize the observation, explanation, and prediction of real world phenomena. Historiographyof science, in contrast, often draws on the historical methods of both intellectual history and social history.
The English word scientist is relatively recent—first coined by William Whewell in the 19th century. Previously, people investigating nature called themselves natural philosophers. While empirical investigations of the natural world have been described since classical antiquity (for example, by Thales, Aristotle, and others), and scientific methods have been employed since the Middle Ages (for example, by Ibn al-Haytham, and Roger Bacon), the dawn of modern science is often traced back to the early modern period and in particular to the scientific revolution that took place in 16th- and 17th-century Europe. Scientific methods are considered to be so fundamental to modern science that some consider earlier inquiries into nature to be pre-scientific.[1] Traditionally, historians of science have defined science sufficiently broadly to include those inquiries.[2]
From the 18th century through late 20th century, the history of science, especially of the physical and biological sciences, was often presented in a progressive narrative in which true theories replaced false beliefs.[3] More recent historical interpretations, such as those of Thomas Kuhn, tend to portray the history of science in different terms, such as that of competing paradigms or conceptual systems in a wider matrix that includes intellectual, cultural, economic and political themes outside of science.

History of science it all starts with the greeks

  1. 1. History of Science
  2. 2. It all starts with the Greeks The Ancient Greeks are seen, in the west, as our intellectual forefathers. From Greece was born philosophy, drama, western artistic aesthetics, geometry, etc., etc., etc. Theology was never an important aspect of Greek thought and Orthodoxy was practically anathema.
  3. 3. Ancient Greek society did not have a permanent priestly class that imposed dogma. Greek Gods & Goddesses were NOT omnipotent nor omniscient.
  4. 4. Aristotle (384-322 BCE) • Tutor to Alex the Great • Scala Natura • His philosophy later adopted by the Christian West • Founded the Lyceum, (peripatetic school) which emphasized natural philosophy.
  5. 5. • Aristotle created a hierarchy of all living things, from simple to more complex. Although he did not mean to imply evolution, it nevertheless ranked all of creation from great to small. • This later became the “Great Chain of Being” – a hierarchically ordered system with God & angels at the top, progressing downward from more to lesser developed (moral/perfect) beings.
  6. 6. Ptolemy • Created a Geocentric model of the universe. • This worked pretty well for a long time – especially for planets. But, eventually, errors would be detected (once math & technology developed more).
  7. 7. Greek Civilization • It is difficult to underestimate the contributions of Greek philosophy, science, art, literature, etc. to our Western way of thinking. Although they were “pagans” (as later Christians would think), much Greek thought was incorporated into the Christian European tradition. Nevertheless, the sense of curiosity that drove Greek intellectual developments would not be adopted in the west until the Renaissance.
  8. 8. European Medieval thinking • After the fall of the Roman Empire (~478 AD), Europe would be politically fragmented and a period of intellectual conservatism would be the norm. • Meanwhile, Arab civilization would be the center of intellectual development – esp. in mathematics, optics, medicine. • In Europe, intellectual activity would be under the purview of the church – monasteries would be the loci of study, contemplation, documentation.
  9. 9. • According to the Church, all that could be known about the world came from the bible. • Creation had been perfect • Degeneration: after people were tossed out of Eden, it was all down hill – the further history moved away from creation, the more evil grew and the 2nd coming would restore God’s kingdom. • Likewise, the further one got from the holy land, the more degenerate
  10. 10. The Day the Universe Changed
  11. 11. The “New World” • The “discovery” of the Americas was one of the most important events in European history (although historians mostly focus on the impact of Europe on the Americas). • There were several troubling aspects to the discovery.
  12. 12. • First, the Bible had absolutely nothing to say about the Americas – not its location, people, history, etc. • Europeans came into contact with people entirely ignorant of God, Christ, etc. • The plants and animals of the Americas were unknown – although there were some that were the same.
  13. 13. • This led to 1) recognition that the Bible was not the ultimate authority on nature 2) debate over the nature of Indigenous people (were they animals or humans?) 3) classification of the animals & plants. 4) the fact that no one knew anything about the Americas sparked curiosity – the need to know.
  14. 14. Of course, there were many other ramifications to European domination of the Americas – • Economic: commerce would eventually lead to the industrial revolution • Power: struggles over control of the colonies and their wealth would spark intense competition between European nations (Spain vs. Britain, etc.) • Politics: Liberalism (our current form of government) would have its first experiment in the Americas (USA).
  15. 15. Our concern here, however, is in science. • The discovery of the new world began a process of separation of church and science. • Many would try to reconcile science & religion, but ultimately, science would largely reject theology as a way of knowing the natural world. • This would be a difficult period with many wounded – but the process was more or less inevitable.
  16. 16. Rene Descartes (1596-1650) •Descartes is often called the 'father' of modern philosophy. •Descartes argued that knowledge is genuinely possible, and that a mathematically-based scientific knowledge of the material world is possible.
  17. 17. Cogito, ergo sum • he rejected religious authority in the quest for scientific and philosophical knowledge (but he was a devout Catholic) • He argued for a rational justification for a universal, mathematical/ quantitative understanding of nature. • We still rely largely on the Cartesian view of the universe – a mechanistic view of nature.
  18. 18. Although Descartes and other philosophers established spaces for coexistence between science and religion, it would still be quite some time before Europe would be able to embrace evolution.
  19. 19. Up until Darwin, the predominant understanding of the world came from the Bible and Church doctrine. In this respect, truth had been revealed (via the Bible and Christ) . . . There was no need to question God’s creation . . . . This set of beliefs meant that people were highly resistant to evidence to the contrary and even went so far to create elaborate explanations to “fit” contradictions into religious belief.
  20. 20. Creationism Several compelling Christian dogmas are important to note: 1) Genesis: GOD created earth in 6 days (don’t forget – he took the last day off). Creation was also centered around Earth & Man (we are in his image).
  21. 21. 2) Relative Youth of the Earth there was a lot of debate about the exact age . . . but most theologians agreed it wasn’t so long ago. If the earth was indeed less than 6000 years old, then gradual change could not have occurred.
  22. 22. Bishop Ussher (1581-1656) • By working backwards from the Bible (so-and-so begat so-and-so), he calculated the first day of creation to have been Sunday, October 23rd , 4004 BC! • Although many have ridiculed this attempt to date the age of the earth, Ussher diligently correlated Middle Eastern and Mediterranean history and scripture to arrive at what was a “reasonable” calculation.
  23. 23. 3) The Permanence of the Earth’s Physical Structure According to Christian thought, the appearance of earth is the result of two factors: 1) Original creation by God. 2) The damage done by the great flood. Otherwise, the earth had not changed over
  24. 24. 4) The Fixity of Species Likewise, after God created plants & animals, these retained their true, original form, generation after generation. - no species had been lost - no species had changed Nevertheless, people did understand the process of selective (or artificial) breeding.
  25. 25. Crack in the armor #1 •Fossils – “figured stones” . . . for some time people considered these evidence of God’s “playful” nature . . . that he had decorated some rocks to as replicas of living things.
  26. 26. John Ray •Natural theology: the doctrine that the wisdom and power of God could be understood by studying His creation.
  27. 27. • Ray spent a great deal of time pondering the relationships of organismal form to function. • Living things showed adaptations to their environments, which for Ray were signs of God's design and hence worthy of study. • Unlike Linnaeus, who focused almost exclusively on classification for its own sake, Ray began to use classification to address questions in physiology, function, and behavior
  28. 28. Argument from Design • Rev. William Paley – Natural Theology “The marks of design are too strong to be got over. Design must have had a designer. That designer must have been a person. That person is GOD” Nature is a watch & GOD is the watchmaker.
  29. 29. Essentialism Due to neo-Platonism, variation in species was disregarded. As long as the ideal form existed (in God’s mind), then subtle, minute variations were insignificant and did not demonstrate change over time.
  30. 30. Evidence supporting evolution prior to Darwin
  31. 31. Uniformitarianism •James Hutton : came up with the observation •Lyell made the ideas popular.
  32. 32. Sir Charles Lyell (1797 – 1875) Wrote: Geological Evidence of the Antiquity of Man in 1863 and Principles of Geology Lyell argued that presently observable Geological processes were adequate to explain geological history; the action of the rain, sea, volcanoes, earthquakes, etc., explained the geological history of more ancient times.
  33. 33. Jean-Baptiste Lamarck (1744-1829) Inheritance of acquired characteristics
  34. 34. Georges Cuvier (1769- 1832) Catastrophism Opposed Lamarck Convinced others that extinction was a fact Known as the father of Comparative anatomy
  35. 35. Extinction Cuvier’s work demonstrated that some species had become extinct  this raised two issues: 1) Why would God allow some of his creations to disappear. 2. Young earth theory: how could so many strange species go extinct, be covered by sediments, if the earth was young?
  36. 36. Sequence of Fossil types • By the 1830’s there was general recognition that fossils had been organisms. • Further, it was apparent that older strata contained very simple animals. As one moved through time, the organisms became more and more complex. • There was no reason to believe that catastrophes had occurred . . . .
  37. 37. Existence of Rudimentary Organs • By the late 1700s, biologists recognized that some animals retained parts they didn’t use • snakes with vestiges of limbs • Flightless insects retained stunted wings. • These observations contradicted the argument from design theory.
  38. 38. Structural similarities • A human hand, fin of seal, wing of bat, etc. all show similar structure. • While Creationists argued that this was evidence of the uniform plan of God, evolutionists would argue that this was due to a common evolutionary past.
  39. 39. Embryological development • 18th century comparative anatomists noted that as animals went through embryonic development, it was difficult in the early stages to tell what type of animal it was. Chicken, lizard and human embryos look very similar and have similar structures (gill slits, etc.). • Darwin would use this to argue common descent.
  40. 40. Artificial Selection •Animal breeders had demonstrated that species are not immutable . . . That is, they can be changed through selective breeding.
  41. 41. Charles Darwin
  42. 42. Thomas Malthus (1766- 1834) • Essay on the Principle of Population (1798) • In nature, organisms produce far more offspring than can survive. • Man too is capable of overproducing if left unchecked (advocated limiting family size) • Famine would become globally epidemic and eventually consume Man.
  43. 43. Alfred Russel Wallace If not for me, Darwin would not have published his ideas . . Yet, no one remembers my name!! If not for me, Darwin would not have published his ideas . . Yet, no one remembers my name!!
  44. 44. Alfred Russel Wallace (1823- 1913) • Travels to Amazon & Malay Archipelago (1848-62) • Independently developed theory of natural selection (drew same conclusion from Malthus as had Darwin) • Wrote an essay “On the Tendency of Varieties to Depart Indefinitely From the Original Type” • Send ms off to Darwin for review – Darwin submitted his own, beating Wallace to
  45. 45. Herbert Spencer •Coined the term “Survival of the Fittest” •Tried to apply evolution to human populations and demonstrate moral superiority of Europeans
