The Novum Organumfully Novum Organum Scientiarum ‘new instrument of science’is a philosophical work by Francis Baconwritten in Latin and published in The title is a reference to Aristotle ‘s work Organonwhich was his treatise on logic and syllogism.

Instauratio Magna

In Novum OrganumBacon details a new system of logic he believes to be superior to the old ways of syllogism. This is now known as the Baconian method. For Bacon, finding the essence of a thing was a simple magns of reductionand the use of inductive reasoning. In finding the cause of a ‘phenomenal nature’ such as heat, one must list all of the situations where heat is found. Then another list should be drawn up, listing situations that are similar to those of the first list except for the lack of heat.

A ,agna table lists situations where lnstauratio can vary. The ‘form nature’, or cause, of heat must be that which is common to all instances in the first table, is lacking from all instances of the second table and varies by degree in instances of the third table.

The title page of Novum Organum depicts a galleon passing between the mythical Pillars of Hercules that stand either side of the Strait of Gibraltarmarking the exit from the well-charted waters of the Mediterranean into the Atlantic Ocean.

The Pillars, as the boundary of the Mediterranean, have been smashed through by Iberian sailors, opening a new world for exploration. Bacon hopes that empirical investigation will, similarly, smash the old scientific ideas and lead to greater understanding maggna the world and heavens. Bacon’s work was instrumental in the historical development of the scientific method. His technique bears a resemblance to the modern formulation of the scientific method in magma sense that it is centered on experimental research.

Bacon’s emphasis on the use of artificial experiments to provide additional observances of a phenomenon is one reason that he is often considered “the Father of the Experimental Philosophy” for example famously by Voltaire. On the other hand, modern scientific method does not follow Bacon’s mafna in its details, but more in the spirit of being methodical and experimental, and so his position in this regard can be disputed.

Bacon begins the work with a rejection of pure a priori deduction as a means of discovering truth in natural philosophy. Of his philosophy, he states:.

Now my plan is as easy to describe as it is magnx to effect. For it is to establish degrees of certainty, take care of the sense by a kind of reduction, but to reject for the most part the work of the mind that follows upon sense; in insgauratio I mean to open up and lay down a new and certain pathway from the perceptions of the senses themselves to the mind.

The emphasis on beginning with observation pervades the entire work. In fact, it is in the idea that natural philosophy must begin with the senses that we find the revolutionary part of Bacon’s philosophy, and its consequent philosophical method, eliminative induction, is amgna of Bacon’s most lasting contributions to science and philosophy. Novum organum was actually published as part of a much larger work, Instauratio magna magns great restoration’.

Originally intending Instauratio magna to contain six parts of which Novum organum constituted the secondBacon did insrauratio come close to completing this series, mana parts V and VI were never written at all.

Novum organumwritten in Latin and consisting of two books of aphorismswas included in the volume that Bacon published in ; however, it was also unfinished, as Bacon promised several additions to its content which ultimately remained unprinted.

In the first book of aphorisms, Bacon criticizes the current state of natural philosophy. The object of his assault consists largely in the syllogisma method that he believes to be completely inadequate in comparison to what Bacon calls “true Induction “:.

The syllogism is made up of propositions, propositions of words, and words are markers of notions. Thus if the notions themselves and this is the heart of the matter are confused, and recklessly abstracted from things, nothing built on them is sound. The only hope therefore lies in true Induction.

In many of his aphorisms, Bacon reiterates the importance inwtauratio inductive reasoning. Induction, methodologically opposed to deduction, entails beginning with particular cases observed by the senses and then attempting to discover the general axioms from those observations. In other words, induction presupposes nothing.


Deduction, on the other hand, begins with general axioms, or first principles, by which the truth of particular cases is extrapolated. Bacon emphasises the strength of the gradual process that is inherent in induction:. There are and can only be two ways of investigating and discovering truth.

The one rushes instaurati from the sense and particulars to axioms of the highest generality and, from these principles and their indubitable truth, goes on to infer and discover middle axioms; and this is the way in current use.

The other way draws instauuratio from the sense and particulars by climbing steadily and by instaauratio so that it reaches the ones of highest generality last of all; and this is the true but still untrodden way. After many similar aphoristic reiterations of these important concepts, Bacon presents his famous Idols.

Novum organumas suggested by its name, is focused just as much on a rejection of received doctrine as it is on a forward-looking progression. In Bacon’s Idols are found his most critical examination of man-made impediments which mislead the mind’s objective reasoning. Ibstauratio appear in previous works but were never fully fleshed out until their formulation in Novum organum:. For people falsely claim that human sense is the measure of things, whereas in fact all perceptions of sense and mind are built to the scale of man and not the universe.

Bacon includes in this idol the instaufatio of the human imagination to presuppose otherwise unsubstantiated regularities in nature. An example might be the common historical astronomical assumption that planets move in perfect circles. These “belong to the particular individual. For everyone has besides vagaries of human nature in general his own special cave or den which scatters and discolours the light of nature. Now this comes either of his own unique and singular nature; or his education and association with others, or the books he reads and the several authorities of those whom he cultivates and admires, or the different impressions as they meet in the soul, be the soul possessed and prejudiced, or steady and settled, or the like; so that the human spirit as it is allotted to particular individuals is evidently a variable thing, all muddled, and so to speak a creature of chance This type of idol stems from the particular life experiences of the individual.

Variable educations can lead the individual to a preference for specific instauuratio or methods, which then corrupt their subsequent philosophies. Bacon himself gives the example of Aristotle, “who made inshauratio natural philosophy a mere slave to his magnaa. These are “derived as if from the mutual agreement and association of the human race, which I call Idols of the Market on account of men’s commerce and insauratio. For men associate through conversation, but words are applied according to ibstauratio capacity of ordinary people.

Therefore shoddy and inept application of words lays siege to the intellect in wondrous ways” Aphorism instauraito Bacon considered these “the greatest nuisances of them all” Aphorism Because humans reason through the use of words they are particularly dangerous, because the received definitions magnz words, which are often falsely derived, can cause confusion.

He outlines two subsets of this kind of idol and provides examples Aphorism These idols manifest themselves in the unwise acceptance of certain philosophical dogmas, namely Instaueatio sophistical natural philosophy named specifically in Aphorism 63 which was corrupted by his passion for logic, and Plato’s superstitious philosophy, which relied too heavily on theological principles.

After enumerating the shortcomings of the current and past natural philosophies, Bacon can now present his own philosophy and methods.

Bacon retains the Aristotelian causes, but redefines them in interesting ways. While traditionally the final cause was held as most important among the four material, formal, efficient, and finalBacon claims that it is the least helpful and in some cases actually detrimental to the sciences aph. For Bacon, it is the formal cause which is both the most illusive and most valuable, although each of the causes provides certain practical devices.

By forms and formal causes, Bacon means the universal laws of nature. To these Bacon attaches an almost occult like power:. But he who knows forms grasps the unity of nature beneath the surface of materials which are very unlike.

Thus is he able to identify and bring about things that have never been done before, things of the kind which neither the vicissitudes of nature, nor hard experimenting, nor pure accident could ever have actualised, or human thought dreamed of.

And thus from the discovery of the forms flows true speculation and unrestricted operation aphorism 3. In this second book, Bacon offers an example of the process that of what he calls true induction. In this example, Bacon attempts to grasp the form of heat.


The first step he takes is the surveying of all known instances where the nature of heat appears to exist. To this compilation of observational data Bacon gives the name Table of Essence and Presence. The next table, the Table of Absence in Proximityis essentially the opposite—a compilation of all the instances in which the nature of heat is not present.

Because these are so numerous, Bacon enumerates only the most relevant cases. Lastly, Bacon attempts to categorise the instances of the nature of heat into various degrees of intensity in his Table of Degrees. The aim of this final table is to eliminate certain instances of heat which might be said to be the form of heat, and thus get closer to an approximation of the true form of heat.

Such elimination occurs through comparison. For example, the observation that both a fire and boiling water are instances of heat allows us to exclude light as the true form of heat, because light is present in the case of the fire but not in the case of the boiling water.

Through this comparative analysis, Bacon intends to eventually extrapolate the true form of heat, although it is clear that such a goal is only gradually approachable by degrees. Indeed, the hypothesis that is derived from this eliminative induction, which Bacon names The First Vintageis only the starting point from which additional empirical evidence and experimental analysis can refine our conception of a formal cause.

The “Baconian method” does not end at the First Vintage. Bacon described numerous classes of Instances with Special Powers, cases in which the phenomena one is attempting to explain is particularly relevant. These instances, of which Bacon describes 27 in Novum Organumaid and accelerate the process of induction.

They are “labour-saving devices or shortcuts intended to accelerate or make more rigorous the search for forms by providing logical reinforcement to induction. Aside from the First Vintage and the Instances with Special Powers, Bacon enumerates additional “aids to the intellect” which presumably are the next steps in his “method. These additional aids, however, were never explained beyond their initial limited appearance in Novum Organum.

It is likely that Bacon intended them to be included in later parts of Instauratio magna and simply never got to writing about them. As mentioned above, this second book of Novum organum was far from complete and indeed was only a small part of a massive, also unfinished work, the Instauratio magna.

Both thinkers were, in a sense, some of the first to question the philosophical authority of the ancient Greeks.

Bacon and Descartes both believed that a critique of preexisting natural philosophy was instauratko, but their respective critiques proposed radically different approaches to natural philosophy. Two over-lapping movements developed; “one was rational and theoretical in approach and was headed by Rene Descartes; the other was practical and empirical and was led by Francis Bacon.

On the one hand, Descartes begins with a doubt of anything which cannot be known with absolute certainty and includes in this realm of doubt the impressions of sense perception, and thus, “all sciences of corporal things, such as physics and astronomy. In this method of deduction, the philosopher begins by examining the most general axioms such as the Cogitoand then proceeds to determine the truth about particulars from an understanding of those general axioms.

Conversely, Bacon endorsed the opposite method of Induction, in which the particulars are first examined, and only then is there a gradual ascent to the most general axioms. While Descartes doubts the ability of the senses to provide us with accurate information, Bacon doubts the ability of the mind to deduce truths by itself as it is subjected to so many intellectual obfuscations, Bacon’s “Idols.

So, in a basic sense the central difference between the philosophical methods of Descartes and those of Bacon can be reduced to an argument between deductive and inductive reasoning and whether to trust or doubt the senses. However, there is another profound difference between the two thinkers’ positions on the accessibility of Truth.

Descartes professed mavna be aiming at absolute Truth. It is questionable whether Bacon believed such a Truth can be achieved. In his opening remarks, he proposes “to establish progressive stages of certainty.
