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)

Outside France the epistemology of G. Bachelard is unknown ; in France his influence is considerable, especially on philosophers like L. Althusser, M. Foucault, G. Canguilhem, J. Hyppolite, M. Serres, G. G. Granger, D. Lecourt and many others. Bachelard occupies a strategic point on the crossroads of all theoretical debates concerning science. The fact that he seems to give satisfactory answers on the problems which have risen after the breakdown of the logical-positivistic philosophy of science, justifies an exposition and evaluation (...) of his original contribution to philosophy. The author distinguishes the following items. 1. The determination of Bachelards philosophy as a scientific philosophy which is wedded to a history of the sciences, especially the natural sciences. 2. The 'systematicity' as the criterium of science against other, traditional, criteria like empiricalness, logical deducibility, correspondence with reality and so on. 3. The rectification-principle : the formation of a scientific system cannot be conceived otherwise than as the restructuring or reorganisation of the ruling system or system-sets. 4. The transformation of scientific knowledge shows many discontinuities in all its phases and branches. Bachelard calls them ruptures. 5. The translation of a theory into another, more coherent and comprehensive one, is baptised as a 'dialectisation' of the concept. By a dialectisation a system is both generalised and specified. Formal logic, which is based on identity and the principle of the excluded middle, is not able to interprete this dynamic aspect of scientific thinking. 6. Central in Bachelards philosophy is also the concept of recurrence. Each new organisation of the scientific system (global or partial) sheds new light on their history and their logical foundations. History has to be rewritten after each progress. Recurrence, however, also has systematic implications. Science always desimplifies its own evidences. 7. The scientist has to demolish the obstacles which he made himself by surcharging the content of the concepts not in use and by not assimilating them in the system. 8. Bachelards philosophy of science is both idealistic and realistic ; the phenomenology becomes phenomenotechnique under the hands and in the brains of the scientist. 9. He always denies (negativity) the earlier theories and objects by incorporating them in new relationships. 10. This constructive aspect of theory formation is the same in natural science and mathematics. Bachelard opposes the logical-positivistic idea that these are methodically dissimilar. In a critical commentary the author discusses the question of 'dialectical logic' in the sciences, in relation to some recent research in this field by I. Lakatos en Errol E. Harris. In his opinion the epistemology of Bachelard affords a creative renewal of the understanding of science, although further research is needed in many aspects. (shrink)

The traditional philosophical treatises on culture, who mostly started from neohumanistic inheritance, recently got a serious, though revolutionary partner for discussion in the person of Herbert Marcuse. The ideas, which this thinker launches on culture and society, are not loose propositions or emotionally determined interpretations, but form a structural theory, that earns further consideration. This article tries to give a survey of his opinions on this theme as well as a critical look at their suppositions and coherence. Eventually are discussed (...) Marcuse's concept of the prevailing culture as an affirmative culture, i.e. an attitude in which one accepts the existing social conditions and resigns to them. After that it discusses Marcuse's deepened interpretation of culture as a civilisation, in which the repression of the truely human needs and impulses is so to say institutionalised, and finally his matured judgement on the recovery of culture by means of the play-impulse and sufficient space for speculative and practical negation in a non-operational dimension. Retrospecting we stated that Marcuse is taking back now something of his original, marxistic aversion of the theoretical attitude, that is inaugured by the Greeks. One must also criticise his unilateral reviewing of the technical and social acquisitions of mankind. But his realising and objectifying of the old spiritual ideal of culture is no doubt a profit in relation to the neo-humanistic philosophy of culture. (shrink)

Philosophers of science don't very often discuss the place of mathematics between other sciences or the meaning of mathematics for other sciences. They consider mathematics as a formal language with mainly analytical statements about the use of symbols (Carnap, Russell, Ayer ). Originally Wittgenstein defended this formalistic interpretation of mathematics in his TLP. Gradually, however, he develops himself towards an intuitionistic and ontological position, in which mathematics is conceived as the central and therefore normative part of our thought (of course (...) : on what there is and how it is). Mathematical science plays the role of logic in relation to other sciences. Its universal applicability and efficiency are consequences of its creating beings on a necessary level, in virtue of the number of its relations (always still by substitution). This highly important philosophy of mathematics (misinterpreted by Crispin Wright) starts with his lectures in Cambridge (in the thirties ) and reaches its culmination in the Remarks on the Foundations of Mathematics and in On Certainty. In a second part this philosophical determination of mathematical reasoning is traced backwards through history. David Hume's contribution is reinterpreted from a new point of view. Inside the total field of our beliefs he distinguishes between different sciences with the critérium of the intricacy of relations between items of our knowledge field. The more and stronger these relations, the more forceful and necessary their influence on the remaining parts of the system of our belief. So mathematics is in the centre, the loose reveries of our fancy on the periphery. Quine's representation of ‘the tribunal of sense experience’, by which the total field should be judged and corrected, must be disqualified. Hume's dictum ‘Whatever we conceive, we conceive it to be existent’ reveals sharply that this evaluative and corrective role is performed by the necessary thoughts (or, if one likes it so, ‘realities’) of mathematical science. That reason and especially mathematical reason is the highest judge on the population and structure of our world and a very precious heritage of Pythagorism and Platonism. From the sources of Sextus Empiricus and Aristotle the author tries to reconstruct exactly the original assertion of Pythagoristic mathematical philosophy, which has nothing to do with a naive hypostazation of numbers or a kabbalistic number mysticism. Philolaos' saying, that some propositions are stronger than we, is demonstrated to refer to mathematical laws. The pythagorical position is fully integrated in Plato's dialectical philosophy. Mathematics is the great mediator towards the intuition of true being, the ‘metaxu’ between sensible phenomena and ideas. This tradition of philosophical taxation of mathematics as the ‘logic of science’ is broken by Aristotle, who didn't use mathematics in his qualitative natural science and considered mathematics as an abstract science (about the quantitative aspect of being). Moreover, he disowned its logical role and created a special science for this task. Human reason is mathematical in so far it is sure of its language and thought, which is excellently expressed by the Greek μαθηματιxα (= what can be understood, learned and taught) and by the Dutch word ‘wiskunde’ (= science of what is certain). The remarks and reflections of Wittgenstein have produced a new perspective on the placevalue (‘Stellenwert’) of mathematics among all possible sciences and beliefs and have proven that its onto-logical purport is an unavoidable implication.

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)

Overzicht van de invloed van klassieke auteurs op het werk van de Nederlandse wijsgeer.

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)

A complete translation of Aristotle's classic that is both faithful and readable, along with an introduction that provides the modern reader with a means of understanding this seminal work and its impact on our culture. In this volume, Joe Sachs (translator of Aristotle's _Physics, Metaphysics,_ and the _Nicomachean Ethics _)also supplements his excellent translation with well-chosen notes and glossary of important terms. Focus Philosophical Library translations are close to and are non-interpretative of the original text, with the notes and a (...) glossary intending to provide the reader with some sense of the terms and the concepts as they were understood by Aristotle’s immediate audience.

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)
