  1. Scientific Revolutions: Historical Perspective  New visions on the Nature of Science: Bacon’s Empiricism

  2. Francis Bacon (1561-1626)

  3. Francis Bacon (1561-1626) Instauratio Magna NovumOrganum(1620) "True Direction Concerning the Interpretation of Nature."

  4. Francis Bacon (1561-1626) InstauratioMagna NovumOrganum(1620) Multi pertransibunt et augebiturscientia("Many will pass through and knowledge will be the greater").

  5. Multi pertransibunt et augebiturscientia("Many will pass through and knowledge will be the greater").

  6. Francis Bacon (1561-1626) Novum Organum The honor of the ancient authors, and indeed of all, remains untouched, since the comparison I challenge is not of wits or faculties, but of ways and methods, and the part I take upon myself is not that of a judge, but of a guide.

  7. Francis Bacon (1561-1626) Novum Organum Nor do I think that it matters any more to the business in hand whether the discoveries that shall now be made were long ago known to the ancients, and have their settings and their risings according to the vicissitude of things and course of ages, than it matters to mankind whether the new world be that island of Atlantis with which the ancients were acquainted, or now discovered for the first time. For new discoveries must be sought from the light of nature, not fetched back out of the darkness of antiquity.

  8. Francis Bacon (1561-1626) Logic and Induction All Men are Mortal Socrates is a Man Socrates is Mortal

  9. All Men are Mortal Socrates is a Man Socrates is Mortal There are and can be only two ways of searching into and discovering truth. The one goes from the senses and particulars to the most general axioms, and from these principles, the truth of which it takes for settled and immovable, proceeds to judgment and to the discovery of middle axioms. And this way is now in fashion. The other derives axioms from the senses and particulars, rising by a gradual and unbroken ascent, so that it arrives at the most general axioms last of all. This is the true way, but as yet untried.

And this way is now in fashion. The other derives axioms from the senses and particulars, rising by a gradual and unbroken ascent, so that it arrives at the most general axioms last of all. This is the true way, but as yet untried.

  11. Francis Bacon (1561-1626) Idols: “false notions which are now in possession of the human understanding, and have taken deep root therein, … they will again in the very instauration of the sciences meet and trouble us, unless men being forewarned of the danger fortify themselves as far as may be against their assaults."

  12. Francis Bacon (1561-1626) "Idols of the Tribe“ "Idols of the Cave" "Idols of the Marketplace" "Idols of the Theatre“

  13. Idols of the Tribe: have their foundation in human nature itself, and in the tribe or race of men. Tendency to perceive more order and regularity in systems than truly exists there. Due to people’s preconceived ideas about things. (“The fiction that all celestial bodies move in perfect circles”)

  14. Idols of the Cave: the idols of the individual man. For everyone (besides the errors common to human nature in general) has a cave or den of his own, which refracts and discolors the light of nature, owing either to his own proper and peculiar nature; or to his education and conversation with others. A tendency to inappropriately extrapolate from norms or tenets that apply to one’s own culture and social group.

  15. Idols of the Marketplace: idols due to words (i.e. related to the interaction between people – which occurs at the market place) “They are either names of things which do not exist … or they are names of things which exist, but yet confused and ill-defined, and hastily and irregularly derived from realities.”

  16. Idols of the Marketplace: idols due to words (i.e. related to the interaction between people – which occurs at the market place) “Of [this] kind are Fortune, the Prime Mover, Planetary Orbits, Element of Fire, and like actions which owe their origin tofalseand idle theories.”

  17. Idols of the Theater: following accepted academic dogmas and not asking questions about the world. “The Rational School of philosophers snatches from experience a variety of common instances, neither duly ascertained nor diligently examined and weighed, and leaves all the rest to meditation and agitation of wit.”

  18. Idols of the Theater: following accepted academic dogmas and not asking questions about the world. “The Empirical School of philosophers … having bestowed much diligent and careful labor on a few experiments, have thence made bold to educe and construct systems, wresting all other facts in a strange fashion to conformity therewith.”

  19. Idols of the Theater: following accepted academic dogmas and not asking questions about the world. Alchemists did some detailed experiments, unlike the rational school. But they devised a theory of matter that went far beyond what their experiments really supported.

  20. Idols of the Theater: following accepted academic dogmas and not asking questions about the world. William Gilbert did detailed work on properties of magnets but then generalized wildly, suggesting that the orbit of planets around the sun is due to magnetism.

  21. Francis Bacon (1561-1626) A critique of Aristotelian causes It is a correct position that true knowledge is knowledge by causes." And causes again are not improperly distributed into four kinds: the material, the formal, the efficient, and the final. But of these the final cause rather corrupts than advances the sciences, except such as have to do with human action. The discovery of the formal is despaired of. The efficient and the material (as they are investigated and received, that is, as remote causes, without reference to the latent process leading to the form) are but slight and superfivial, and contribute little, if anything, to true and active science.
