Scientific Revolutions and Conceptual Change

We will be discussing the concept of revolutions in science and the work of Thomas Kuhn.

Key People: Kuhn; Laktos; Popper.

Key Concepts: Theory; Hypothesis; Fact; Cohen's stages of a revolution; Pre-science; "Normal" Science; Crisis; Paradigm; Incommensurability; "Conjecture & Refutation"; Research programmes;

Suggested Reading to clarify some issues from class:

Sep 1

The Scientific Revolution I: Introduction

The Scientific Revolution saw a radical change in the means by which knowledge was generated and disseminated. We're going to concentrate on astronomy and look at how the developement of instruments and experiments influenced the development of scientific thought.

Key People: Copernicus; Brahe; Kepler; Galileo; Bacon; Hooke;

Key Concepts: The Scientific Revolution; Ptolemaic system; Copernican System;

Sep 3

The Scientific Revolution II: Newton

We are going to concentrate on the life of Isaac Newton and his monumental Principia.

Key people: Newton; Hooke; Leibnitz;

Key concepts: Conic sections; Centripetal force; "active principles"; inverse-square law; mass; laws of motion; universal law of gravitation; vortices; gravity as fact, pathway & mechanism;

Required reading:

  • Squashed Philosophers version of Principia (Newton in 3,000 words)
  • Voltaire discussed Newton's ideas in his Letters Concerning the English Nation (1733) and offers a clear overview of how Newton's system differed from Descartes. Letter's XIV and XV are worth reading. [pdf]

Suggested reading for the Newtonophile:

  • A summary overview of the Principia [pdf]
  • The first three sections of Book I of Principia [pdf] - the limit of what Newton felt readers would understand of his methodology. Take a quick look at it so as to get a feel for his analytical style. Newton suggested that readers could then understand Book III.

Natural Theology in the Eighteenth Century

Natural theology, or natural religion, the inferring of the existence and characteristics of the Christian god from observations of nature, has a long tradition. The argument can actually be traced back to Plato and Aristotle and was christianized by Thomas Aquinas. Natural theology received a boost during the Scientific Revolution with the writings of such individuals as Isaac Newton but reached its most elegant expression in Paley's 1802 work.

William Paley (1743 - 1805) was an English churchman and author of popular apologetic works. One of these - Natural Theology - begins by making his famous watchmaker argument; just as the complexity of a watch implies a watchmaker, so too the complexity of living things implies a designer. The latter portion of the book (and the majority of our reading) attempts to argue for the attributes of God from observations of nature.

Key people: Newton; Paley; Hume

Key concepts: Natural theology; a priori and a posteriori proofs; evidentialism; Theism vs Deism; mechanical philosophy; Paley's argument as abduction to the best explanation; Paley's argument as argument from analogy; Argument to/from design; Hume's critique of natural religion; The problem of evil;

Required reading:

  • Newton, "General Scholium" to Principia [pdf]
  • Newton, "Query 31" of Opticks [pdf]
  • Paley, Natural Theology [pdf]
