Called the father of empiricism, Sir Francis Bacon is credited with establishing and popularizing the “scientific method” of inquiry into natural phenomena. In stark contrast to deductive reasoning, which had dominated science since the days of Aristotle, Bacon introduced inductive methodology—testing and refining hypotheses by observing, measuring, and experimenting. An Aristotelian might logically deduce that water is necessary for life by arguing that its lack causes death. Aren’t deserts arid and lifeless? But that is really an educated guess, limited to the subjective experience of the observer and not based on any objective facts gathered about the observed. A Baconian would want to test the hypothesis by experimenting with water deprivation under different conditions, using various forms of life. The results of those experiments would lead to more exacting, and illuminating, conclusions about life’s dependency on water. |

This copy contains only the second of the six parts of Bacon’s planned great intellectual “restoration,” the Novum organum, followed by a sketch of the third part. (Works that represent the first and third parts were published later; of the fourth and fifth parts only prefaces were written; the sixth was never begun.) The Novum organum, or “new instrument,” a reference to Organon, Aristotle’s work on logic, is Bacon’s most significant work, laying out his guidelines for interpreting nature. Unlike the ancients, who often contended that nothing can be known, he argues here that there are progressive stages of certainty, and he will show how through inductive reasoning they can be achieved. |

Probably the most famous Baconian quote, usually translated from the Latin thus: Man, being the servant and interpreter of Nature, can do and understand so much and so much only as he has observed in fact or in thought about the order of Nature: beyond this he neither knows anything nor can do anything [p. 47]. The statement is the foundation of his scientific approach to acquiring knowledge. Later in the book, Bacon writes that printing, gunpowder, and the compass have revolutionized the world. But, of course, his scientific “method” (he never actually used that word) would have even more far-reaching effects. From our perspective today, what hasn’t it touched?Bacon’s thinking, applied to cartography, leads logically to thematic maps—particularly the quantitative variety—for they are visual hypotheses, either posed or proven, created from measurable, hence verifiable, data about the natural (physical and social) world. |
