In lieu of an abstract, here is a brief excerpt of the content:Hume Contra Spinoza? Wim Klever In Book 1 ofthe TreatiseofHumanNature1 Spinoza enjoys thehonour ofbeing the only figure from the history of philosophy and science to be explicitly and extensively discussed by Hume. This honour is, however, a dubious one as the treatment he gets is not so friendly. The passage (T 232-51) is full of insults and denunciations: Spinoza is referred to as "that famous atheist" (T 241), (...) and characterized as "universally infamous" (T 240). His doctrine contains "a true atheism" (T 240). His theory about the thinking substance is an "hideous hypothesis" (T 241); Hume does not want to enter "farther into these gloomy and obscure regions" (T 241), although he spends ten pages on the subject. Richard Popkin2 suggests on account ofthis not too well studied section: "In introducing Spinoza into the discussion of the immateriality ofthe soul, Hume follows what was common practice in his day." This statement, if true, raises the question whether Hume was sincere in writing these 'satanicverses'. Does he, after all, hide the backside of his tongue? This would bring him pretty well in line with two of his English forerunners; with Hobbes about whom Aubrey recorded: "He toldme he [Spinoza]had outthrown him [Hobbes] a bar's length, for he [Hobbes] durst not write so boldly," and with Locke, who possessedinhis privatelibraryall Spinoza's worksbutnonetheless, for one reason or another, refused to assess the theories of "those decried names," saying "I am not so well read in Hobbes or Spinoza as to be able to say what were their opinions in this matter" (namely the pre-existence ofthe soul).4 One commentator, named Gilbert Boss, wrote a two volume dissertation in order to argue for the fundamental opposition between the philosophical systems of both thinkers. In this paper I wish to propose another view and to defend their overall agreement. I will not do so with regard to their thought on religion (as this is already done byPopkin), but I shall more specificallyfocuson the theoretical (mainly epistemological) part oftheir work. Coming to Hume's text the reader of Spinoza's work who is, moreover, convinced by his geometrical demonstration of the propositions, does feel himself quite well at home chez Hume. Hume's is not another world for him. Apart from the question who is the real first modern thinker, Descartes, Hobbes, Spinoza or Hume, there is much common in their treatises on man and world, not only methodologically. Hume's rejection of "the antient philosophy," in Volume XVI Number 2 89 WIM KLEVER which he criticizes the "fictions... concerning substances, and substantial forms, and accidents, and occult qualities" (T 219), "sympathies, antipathies, and horrors ofa vacuum" (T 224) could have been written by the three other candidates as well. In fact every one of thoseitems maybe tracedoutin Spinoza's work; compare, for instance, JSp 136 ("doctrinam illam puerilem et nugatoriam de formis substantialibus, qualitatibus etc.") or 2 PPC 8s ("Quare omnia ilia figmenta de sympathie et antipathie ut falsa sunt reicienda... Nunquam dicendum erit, quod corpus aliquod movetur, ne detur vacuum; sed tantum ex alterius impulsu"). But let us go to the main theme in Book 1 ofthe Treatise, already present in Part 1, Section 1, "Ofthe Origin ofour Ideas." All our ideas result from impressions, themselves also being ideas or perceptions, though withmoreforce andliveliness. The original perceptions aresaid to be "the causes of our ideas" (T 5). We find the impressions in our mind and their effects, our ideas. Hume does not explain the cognitive status ofthe impressions by reducing them to non-cognitive processes. The "universe of the imagination" (T 68) is a world apart, irreducible to matter; we can't step out ofit, "since nothing is ever present to the mind but perceptions, and since all ideas are deriv'd from something antecedently present to the mind" (T 67). Ideas, whatever their character (about external existences or not), can only be explained by other ideas. Hume carefully avoids the category mistake of transcending the border from mental to material things and keeps consequently, at least methodologically, to the absolute caesura between mind and body. The Spinozistic reader must necessarily feel sympathy for this position. The attributes of... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:More About Hume's Debt to Spinoza Wim Klever In a recent contribution to the question of Hume's relationship to SpinozaIadvocatedamoreorlessSpinozisticinterpretationofthefirst bookofA Treatise ofHumanNature.1 Ofthe Understanding, sowasmy claim, is not only very close to De natura et origine mentis (Ethica, second part) as far as its main affirmations are concerned; the convergence ofexternal and internal evidence makes it also probable that there is a remarkable influence from the one's (...) work on the other and, accordingly, that Hume's defamation of Spinoza's system might well have been disingenuous. This last point was previously also suggested by Richard Popkin in an article in which he compared Hume's philosophy ofreligion with Spinoza's.2 What motivated me to continue my research in this field? To say itinone word: the unintendeddiscoveryofmanystrikingresemblances betweenHume's secondbook, OfthePassions,andSpinoza'sthirdpart, De origine et natura affectuum. I happened to become a member of a group ofinterested people who concentrate on reading Hume, and, on the other hand, I had acquired some expertise as a Spinoza scholar for quite a number of years, so that I could not avoid seeing the commonaUties between the two philosophers. It seems to be fully impossible to explain the resemblances—which I, ofcourse, will show below—by referring to the Spinoza-article in Bayle's Dictionaire historique et critique (a source once mentioned by Hume in a letter to a London friend), since Bayle does not spend a word to the human passions. It is further a hard fact that there do not exist other written sourcesfrom which Humemighthave drawnhisSpinozisticinspiration in his French period apart from the Ethics; all available literature of the time turned around the questions theism versus atheism and free will versus determinism, without entering into the details ofhuman emotions.3 Only one conclusion was possible for me: Hume musthave been familiar with Spinoza's own text. Either the Chevaher Ramsay, whose intimate he was for some time,4 or anotherintermediaryfigure5 must have raised his interest. The best entrance into the material is constituted by Hume's closing remark in his A Dissertation on the Passions (1757), in which he elucidates what he in fact has been doing in hie analysis of the passions: Volume XDI Number 1 55 WIM KLEVER I pretend not to have here exhausted this subject. It is sufficient formy purpose, ifI have made it appear, that, in the production and conduct of the passions, there is a certain regular mechanism, which is susceptible of as accurate a disquisition, as the laws ofmotion, optics, hydrostatics, or any part ofnatural philosophy.6 In spite ofthe words "a certain," this fragment maynot be interpreted as a metaphorical assessment. The origin and the processes ofhuman passions are purely mechanical. If this is not what Hume intends to declare, he never could have added the phrase that passions are susceptible of exactly the same kind of accurate descriptions as other natural phenomena. This theory of the mechanism of the passions is certainly not Cartesian. Although Descartes, as a physical scientist, was a great promoter of the explanation of things by means of mechanical causality, he in fact did not extend this method to the life ofthe passions. In his dualistic philosophy he ascribes to the human mind (with its free will) the capability to interfere with the passions and even to dominate them.7 In this field it is Spinoza who paves the way for Hume by sharply criticizing Descartes' non-mechanistic explanation ofthe passions. His far-fetched solution ofthe mind-body interactivity by means of the pineal gland and the animal spirits pushing against it, is called "a hypothesis more occult than any occult quality." 8 Spinoza acknowledged that Descartes had good intentions in trying to explain the human affections by their direct causes, but he was inconsistent insofar as he at the same time attempted to demonstrate man's absolute dominion over them. He, Spinoza, on the contrary, "will consider human actions and appetites just as ifit were a question ofUnes, planes and bodies." 9 The analysis of passions is a piece of natural science comparable with geometry, optics10 and hydrostatics, to mention some other fields of Spinoza's research. Hume's statement... (shrink)

In lieu of an abstract, here is a brief excerpt of the content:A Vindication Wim Klever Comparing Hume with Spinoza I am accused ofhaving misread both, at least in certain respects; I would have gone too far in considering Spinoza as an influential root of Hume's thought. On occasion of Dr. Leavitt's criticism I would like to stress the following points: 1. In spite ofWolfson'sendeavourtoreduceSpinozatoAristotelian, scholastic and Jewish sources ofthe Middle Ages, many texts—in fact all texts in which Aristotle (...) ismentioned—constitute aconvincingproof that Spinoza not only rejected,just like Hume, all sorts ofAristotelian and scholastic speculation, buteven showedmuch contemptfor them.1 In the same way there cannot be any doubt that he rejected Maimonides' Jewish Aristotelianism.2 In the TTP he defines his position in sharp contrast to Maimonides. 2.Nominalism means that names may be used for the indication of many items whereas ideas are essentially ideas of particulars. According to Spinoza everything is reflected in its own specific idea,3 whereas names like 'ens', 'aliquid', 'man', etc. may be the sign, sometimes ambiguously but often also without confusion, of more things, which are vaguely conceived. This confused idea, then, is nevertheless the properideaofaparticularblurredimageinthebrains. Some eminent scholars like Stuart Hampshire and Martial Gueroult (I confess: not all ofthem) pretend that Spinoza is a true nominalist. I think the texts (and the whole structure of the system) enforce us to confess that they are right. 3.In the case of common things, that is, (elementary) things common to all beings, the human body included, the ideas of these things are, though particular, common too.4 In spite ofand in line with Hume's agreement with Spinoza's nominalism he does not deny, as Leavitt pretends, the existence of common notions. In "Of the Passions," part 1, section 10, he writes that "according to common notions a man has no power, where very considerable motives Ue betwixt him and the satisfaction of his desires, and determine him to forbearwhathe wishes toperform."5Thispassageis notatallinconflict with Treatise 1.1.7 in which the real existence ofabstract ideas in our mind is refuted. The ideas of things we have in common with other natural beings, may not be called abstract for that reason. This section (T 17-25) is perfectly congruous with Spinoza's position. 4.I keep to my claim that there is a striking parallel between Spinoza's famous distinction between three kinds of knowledge Volume XVII Number 2 209 WIM KLEVER (2 Ethics 40s2) and some statements ofHume. Additional evidence for this claim (compared with what I gave already) is to find in Treatise 1.3.11, where Hume marks "several degrees of evidence,... distinguishing] human reason into three kinds, viz. that from knowledge, from proofs, and from probabilities" (T 124, first emphasis added); and in the Enquiry, where all objects of human reason are dividedinto three (!)kinds as well, namely"Relations ofIdeas... either intuitively or demonstratively certain" and "Matters ofFact."6 Put into a diagram the resemblance becomes even more apparent: Spinoza Ethics opinio/imaginatio ratio intuitio Hume TreatiseEnquiry probabilityMatters of Fact proofdemonstratively knowledgeintuitively Careful comparison ofthe texts shows that the functions attributed to the various kinds ofknowledge are exactly the same in Spinoza as in Hume, contrary to what is suggested by Leavitt. I only need to remind him ofthe 'Spinozistic' opening ofTreatise 1.3.3: "Tis a general maxim in philosophy, that whatever begins to exist, must have a cause of existence... Tis suppos'd to be founded on intuition,... All certainty arises from the comparison of ideas, and from the discovery of such relations as are unalterable" (T 78-79). Both philosophers locate the highest kind of knowledge in the evidence of mathematics and the common properties of nature, explained in physics. Let us not forget that both are fully naturalists, for whom the understanding of things "sub specie aeternitatis" (Spinoza's description of the third kind of knowledge) means in fact the intuition of the particular essence of things in a scientific way. 5.In the TractatusTheologico-Politicus itiscertainly not Spinoza's intention to show that the third kind of knowledge is identical with prophecy. On the contrary, in the first two chapters he clearly demonstrates, in his scientific hermeneutics, that prophecy is... (shrink)

Gravity was a major theme in the seventeenth century scientific discussion. Trendsetters in the renewal of natural science were Galilei and Descartes. The first required a unified theory of all phenomena of gravity ; the second provided one with his vortex-hypothesis, which explained gravity by the mechanical push of subtile bodies of the vortex. This conception was tested and generally followed by Christiaan Huygens, whereas Newton presented the laws of the so called 'attraction' by which he did not at all (...) indicate the causes of those laws of motion. Spinoza comes on the scene of polemics as a critical Cartesian. Motion (of which downward motion of heavy bodies is only one instance) was explained by Descartes, but not so the rest of bodies or the equilibrium in the power relation between opposite forces, neither the reason why in some cases the particles form a hard body. Full fledged mechanism and consistent determinism lead Spinoza to account for rest and solidity in the same way, namely by means of the pressure of small and mostly unvisible bodies in the whirling environment. This paradoxical law was acknowledged as a real and important contribution to physical science by the Dutch spinozistic Cartesians Cuffeler and Overkamp, by the mathematician De Volder, by Spinoza's younger friend Tschirnhaus and in France by Malebranche. By the end of the century it was quite normal to speak about „the gravity of the air” and to consider the gravity of gross bodies as an illusion. (shrink)

One of the main items in Spinoza's philosophy is the non-existence of evil in nature. A thing may be good or bad for other finite beings or may be imagined as evil in itself. A scientific analysis, however, forbids us to attribute an ontological value to the moral concepts originating from our comparison of things. The rather extended correspondence between Spinoza and the Calvinistic merchant Willem van Blijenbergh gives us a lively access to all the ins and outs of the (...) traditional philosophical problem of evil. The four letters in which Spinoza reacts to the questions and objections of Christian dogmatics, constitute nothing less than a full treatise on the subject. Never before this part of the correspondence has been the object of a separate study. The result is not only a clarification of the systematic relevance of Spinoza's theory. Research also throws light on the principles of his reasoning and contributes to a better understanding of his hermeneutics as well as of his attitude towards Cartesianism. (shrink)

In an almost forgotten passage of the Postenor Analytics (Bk I, ch. III) Aristotle argues against 'another school', according to which it is possible to proof things 'by each other and in a circle'. His logical refutation of this opinion became so dominant in the Western philosophical tradition, that the 'vicious circle' has always deemed a crime since. A scientific demonstration has to be built on firm premisses in order to deduce conclusions from them in a straight, ongoing proces, in (...) which one does not have to return to the premisses for a reconsideration of them on the basis of their implications. Although Aristotle does not mention names, he in fact reacts against Plato and the mainstream of Greek thought, which stresses the essential circularity of human argumentation. In the first, the historical part of the treatise the roots of this circular logic are unearthed in the work of Heraclitus and Parmenides, who both defended a ring structure of their metaphysical explication of nature. Truth is described as well-rounded, because you can follow it in a circle, passing through each of its links in turn, back to your startingpoint. The association of circular motion with thought is fully present in the work of Plato, who speeks many times about the 'periforas tès dianoias' and the essential interdependance of our ideas. Not the theory of an anonymous alternative school but Aristotle's own rectilinear formal logic was the exceptional, untraditional standpoint, which, moreover, was in conflict with his explication of divine thinking as 'noèsis noèseôs'. In modern times Hegel, Nietzsche and Heidegger were the main representatives of an anti-Aristotelian attitude. All three reject the logical prohibition of the circular argument, because it is inadequate to the life of concrete scientific thinking. The path of science always turns around towards its origins and results in a correction of its fundamental hypotheses on a higher level. Circularity is considered as a hallmark of sound logical procedure, as a characteristic of excellence in human understanding. The famous 'hermeneutic circle' is interpreted as the modern equivalent of the Hegelian 'Kreislauf and the Greek ' to par'allèlôn'. In the second, the more systematic part of the text the circular nature of our cognitive and scientific behaviour is demonstrated along three different lines. Reflection on the natural language with its finite stock of words, whose meanings are structurally connected, leads us to the so called semiotical circularity. Natural language is a complex network in which circular argumentation is not only unavoidable, but even the only means of explication. We have to work with the material contained in our dictionary, in which the items are defined by each other. The second reason is constituted by the system-orientation of science. In science we try to systematize our knowledge by means of formalisations and abstractions. The development of science can be characterised as a succession of systems, in which every element gets its meaning from the whole organisation. If we accept systematicity as the arbiter of truth, our logic is anti-fundamentalistic and the path of our thought is in fact circular (or better : spiralistic). The third adstruction of our theory is afforded by the coupling, that is realised in a rational proof. We draw conclusions from the coherence of our perceptions, from the reciprocal implications of our ideas. Never any of our ideas is without the repercussions of the movements elsewhere in the field. When we proof something, we also disproof and correct our startingpoints at the same time. The tradition of the circular nature of human thinking is very old, but not antiquated. The accusation of committing a fallacy in the case of circularity in normal and in scientific thinking is unfouded. It is now the formal logicians turn to defend his claim. (shrink)

An accurate analysis of the text shows that the small treatises have a logical structure and a style which is in all aspects unspinozistic. The main points of difference are : a formalistic interpretation of mathematics‚ the opposition between mathematics and physics‚ slavish cartesianism‚ the presence of numerous pleonasms‚ carelessness of expression‚ parade of learning‚ prolixity‚ attention for irrelevant qualities of authors quoted‚ educational purpose. Together with De Vet’s demonstration that the author of SRR and RK is still alive in (...) 1693 (see Tijdschr. v. Filosofie 45‚ 1983) these arguments force us‚ to consign Spinoza’s authorship‚ recently still defended by Petry a.o.‚ to the realm of fancy. (shrink)
