Our focus in this article concerns Leibniz’s views on evil. Our goal is to examine which are the consequences of his conception of moral agency for the moral psychology of the genuinely evil person. For Leibniz, moral failure is an epistemic error since it involves some false practical judgement. Moral maxims may be represented in blind or symbolic cognitions, but then moral agents can misrepresent the evil consequences of their behaviour. Finally, we discuss Leibniz’s view on habits that may help virtuous persons strive for perfection but also enable evil persons to continue sinning.

The advance of mechanism in science and philosophy in the 17th century created a great interest to machines or automata. Leibniz was no exception - in an early memoir Drôle de pensée he wrote admiringly about a machine that could walk on water, exhibited in Paris. The idea of automatic processing in general had a large role in his thought, as can be seen, for example, in his invention of the binary code and the so-called Calculemus!-model for solving controversies. In metaphysics, the idea of an automata was expressed most clearly in the 1695 article New System of the Nature of Substances and their Communication, and the ensuing correspondence with, among others, Foucher, Bayle, Lamy, Jaquelot and Masham. In the article Leibniz discusses the soul as a spiritual machine in the context of pre-established harmony, arguing that God can "give to a substance at the outset a nature or internal force which could produce in it an orderly way (as in spiritual or formal automaton; but a free one, in the case of a substance which is endowed with a share of reason) everything that is going to happen to it, that is to say, all the appearances or expressions it is going to have, and all without the help of any created thing." The basic idea of Leibniz's spiritual machine is that the soul or entelechy is an autonomous and spontaneous unity, consisting of internal active force and producing its own perceptions (both confused and distinct). It is a self-moving machine, driven by its perceptions and appetites, but it follows (without being conscious of it) a lawful series or programme created by God. The entelechy remains the same despite undergoing an infinite number of changes. To Foucher he explained that each state of the individual substance is a consequence of its preceding one, "as if there were only God and the substance in the world". Despite this, the spiritual machine is related not only to God, but through the pre-established harmony to bodies or natural machines. However, as it is not dependent on them, the spiritual machine is superiot to natural machines. In this paper I concentrate on three moral themes related to the spiritual machine: moral deliberation, moral identity and the goal of moral action. All these themes are more or less implicit in the New System, but are discussed in more detail in the ensuing correspondence after the publication of the article. Finally, the themes are given an extended discussion especially in the second book of New Essays on Human Understanding (1704, published 1765), written partly at the same time as some of the correspondence and unpublished related material. I will first give an overview of Leibniz's position concerning the spiritual machine or automaton in the New System and then go on to explore the three moral themes one by one, as they feature in the subsequent correspondence and in the New Essays. I will show that the three topics are essential to the function of the spiritual machine – to Sophie Charlotte Leibniz wrote: "...let us say that everything in bodies happens mechanically, or in accordance with laws of motion, and that everything in the soul happens morally, or in accordance with perceived good or evil." There are many texts that anticipate the views in the New System (notably the unpublished memoir De Affectibus of 1679) and Leibniz continued to discuss its themes later on (in addition to correpondence, for example, in Theodicy of 1710 and Monadology and Principles of Nature and Grace of 1714). Here I focus on the short-term development of Leibniz's views on the topic (around 1695-1705), but I argue that his basic view of the spiritual machine did not change much after finishing the dialogue with Locke in 1704.

G. W. Leibniz developed a new model for rational decision-making which is suited to complicated decisions, where goods do not rule each other out, but compete with each other. In such cases the deliberator has to consider all of the goods and pick the ones that contribute most to the desired goal which in Leibniz’s system is ultimately the advancement of universal perfection. The inclinations to particular goods can be seen as vectors leading to different directions much like forces in Leibniz’s dynamics. The vectorial model of rational decision-making is related to Leibniz’s work with metaphysical physics and the calculus of variations and is a heuristic tool which helps in finding reasonable combinations – in ideal cases optimums - between competing goods. By applying the model, the decision-maker can map and compare outcomes of combinations of goods in question and practice a kind of pseudo-mechanical arithmetic of reasons. A central feature of the model is the possibility to employ geometrical figures to help the conceptualization. In this paper I present the vectorial model, examine its applications in practical cases from political theory, jurisprudence and ethics Leibniz presented, and compare the model to recent theories of acting under uncertainty, such as bounded rationality and optimizing under constraints.

Gottfried Wilhelm Leibnizia (1646–1716) on usein kutsuttu universaalineroksi. Luonnehdinta on varsin osuva ottaen huomioon Leibnizin intressien laajuuden, hänen luovan panoksensa monille eri aloille ja metafyysis-kulttuurisen vision, joka kajasti kaikkien hänen hankkeidensa, niin teoreettisten kuin käytännöllistenkin, taustalla. Leibniz tunnetaan nykyään ennen kaikkea filosofina ja matemaatikkona, mutta ei juurikaan siitä, että hän toimi suuren osan elämästään kahden eri kirjaston hoitajana: Hannoverin herttuallisen kirjaston ja edelleen maineikkaan, Wolfenbüttelissä sijaitsevan Herzog August Bibliothekin. Tämä katsausartikkeli esittelee Leibnizin kirjastouraa ja hänen kirjastonhoitoa koskevia näkemyksiään, jotka eivät omana aikanaan olleet aivan tavanomaisia. Leibnizin universaalikäsityksen mukaan kirjasto ei nimittäin ole kirjoilla täytetty tila vaan heijastus koko inhimillisen tiedon tilasta. Artikkelissa luodaan katsaus aiheesta kirjoitettuun kansainväliseen tutkimuskirjallisuuteen ja Leibnizin kirjastonhoitoa käsitteleviin muistoihin.

In his defense of innateness in New Essays on Human Understanding (1704), Leibniz attributes innateness to concepts and principles which do not originate from the senses rather than to the ideas that we are born with. He argues that the innate concepts and principles can be known in two ways: through reason or natural light (necessary truths), and through instincts (other innate truths and principles). In this paper I will show how theoretical and moral reasoning differ from each other in Leibniz, and compare moral reasoning and instincts as sources of knowledge in his practical philosophy. As the practical instincts are closely related to pleasure and passions, which are by nature cognitive, my emphasis will be on the affective character of instinctive moral action and especially deliberation which leads to moral action. I will argue that inclinations arising from moral instinct, which lead us to pleasure while avoiding sorrow, can direct our moral action and sometimes anticipate reasoning when conclusions are not readily available. Acting by will, which is related to moral reasoning, and acting by instincts can lead us to the same moral knowledge independently, but they can also complement each other. To illustrate the two alternative ways to reach moral knowledge, I will discuss the case of happiness, which is the goal of all human moral action for Leibniz.

Hahmottelen tässä artikkelissa tekoälyn historiaa varhaismodernin filosofian aikakaudella 1600–1700-luvuilla. Esittelemäni aiheet ovat hieman erillisiä toisistaan, mutta yhteistä niille on ajatus komputaatiosta tai automaatiosta, eräänlaisesta mekaanisesta laskemisesta tai toiminnasta, jota voi pitää tekoälyn varhaisena lähtökohtana. On kuitenkin huomattava, että pelkkä komputaatio eli informaation käsittely sinänsä ei riitä tekoälylle – kaikkia näitä pyrkimyksiä leimaa tietynlainen epistemologinen optimismi: automatisoidun ajattelun avulla uskotaan saatavan enemmän laadukasta tietoa ja kenties myös uudenlaisia ajatuksia, kun ajatteluprosessi tulee sujuvammaksi. Tekoälyn varhaishistoria liittyy siis nimenomaan inhimillisen ajattelun mekanisoimiseen ja uskoon siitä, että sen avulla voidaan lieventää ihmismielen rajoituksia ja ajatella paremmin. Yhteistä sekä tekoälyn että tietokoneen historialle on kuitenkin laskennan kehitys.

The famous philosopher Leibniz (1646-1716) was also active in the (cultural) politics of his time. His interest in forming scientific societies never waned and his efforts led to the founding of the Berlin Academy of Sciences. He also played a part in the founding of the Dresden Academy of Science and the St. Petersburg Academy of Science. Though Leibniz's models for the scientific society were the Royal Society and the Royal Science Academy of France, his pansophistic vision of scientific cooperation sometimes took on utopian dimensions. In this paper, I will present Leibniz's ideas of scientific cooperation as a kind of religious activity and discuss his various schemes for the founding of such scientific societies.

One of the features of John Locke’s moral philosophy is the idea that morality is based on our beliefs concerning the future good. In An Essay Concerning Human Understanding II, xxi, §70, Locke argues that we have to decide between the probability of afterlife and our present temptations. In itself, this kind of decision model is not rare in Early Modern philosophy. Blaise Pascal’s Wager is a famous example of a similar idea of balancing between available options which Marcelo Dascal has discussed in his important 2005 article “The Balance of Reason”. -/- Leibniz, however, was not always satisfied with this kind of simple balancing. In his commentary to Locke’s Essay, Nouveaux essais sur l’entendement humain, II, xxi, §66, he presented an alternative model which is based on an idea of plural, mutually conflicting inclinations. This kind of model, called as vectorial theory of rational decision by Simo Knuuttila, fits well with Leibniz’s theory of the soul where volitions are formed as a kind of compromise between different inclinations to different goods. -/- I will present these two models and show how they illustrate the practical rationality of Locke and Leibniz and how their moral philosophies differ, although being similar in certain respects. The topics include Leibniz’s criticism of Lockean hedonism and the discussion of akratic behaviour in II, xxi of Essay and Nouveaux essais.

Leibniz frequently argued that reasons are to be weighed against each other as in a pair of scales, as Professor Marcelo Dascal has shown in his article "The Balance of Reason." In this kind of weighing it is not necessary to reach demonstrative certainty – one need only judge whether the reasons weigh more on behalf of one or the other option However, a different kind of account about rational decision-making can be found in some of Leibniz's writings. In his article "Was Leibniz's Deity an Akrates?" Professor Jaakko Hintikka has argued that Leibniz developed a new vectorial model for rational decisions which is better suited to complicated decisions, where values are complementary to each other. This model, related closely to his work in metaphysics and the philosophy of mind, is a heuristic device which helps in finding rational combinations - and in an ideal case an optimum - between plural inclinations to the good. I shall argue that Leibniz applies more or less implicitly both of these models in his practical rationality. In simple situations he applied the pair of scales model and in more complicated situations he applied the vectorial model.

In §18 of Principles of Nature and Grace, Based on Reason, Leibniz says: ”Thus our happiness will never consist, and must never consist, in complete joy, in which nothing is left to desire, and which would dull our mind, but must consist in a perpetual progress to new pleasures and new perfections.” This passage is typical in Leibniz’s Nachlass. Universal perfection creates in us joy or pleasure of the mind and its source is our creator, God. When this joy is constant, we reach happiness and wisdom which is a kind of standing state of virtue, readiness to practice charity in the best of all possible worlds. However, it also indicates that our knowledge is never perfect. Perfecting our knowledge is a never-ending process which gives us joy in itself and motivates us to act in imitation of God. In this way some passions advance our knowledge and we can create ourselves a passionate habit of knowing more about the world and its perfection. In this paper I try to see this process of self-perfection from a cognitive rather than ethical point of view. While it is clear that in the final stage of wisdom we act mostly on our volitions which are founded on clear and distinct perceptions, it is less clear what cognitive status is to be attributed to our initial perceptions of perfection, our emotions and finally, the intellectual emotions which lead us to perfection and God. I will also reflect the role of the minute perceptions in our struggle for happiness. My argument is that a central cognitive role in Leibniz’s views on self-perfection is held by clear, but confused perfections which are subjective, undemonstrable impressions, shades, feelings. Therefore our ethical action is largely founded on passing, minute feelings rather than on deliberated conscious volitions, although the goal in Leibniz’s moral theory is to change this fact. My discussion is founded on several texts from Leibniz’s later philosophy, such as the discussion following from New System of the Nature and the Communication of Substances of 1695, Leibniz’s letter to Queen Sophie Charlotte of 1702 (also known as On What is Independent in Sense and Matter), New Essays on Human Understanding (1704),  Theodicy (1710) and naturally Leibniz’s most important epistemological text, Meditations of Truth, Knowledge and Ideas (1684).

Tyynen rauhallisesti, traagisen ennenaikaisesti, koomisen kommelluksen seurauksena, arkipäiväisen banaalisti... Filosofin kuolema sisältää neljäkymmentä tarinaa siitä, miten filosofi kohtaa kuoleman. Mitä Pythagoras ajatteli kuolemanjälkeisestä elämästä? Mikä oli Sokrateen itsemurhan tausta? Entä miten esimerkiksi Platon, Pyrrhon, Aristoteles, Plotinos, Avicenna, Descartes, Hume, Kant, Hegel, Schopenhauer, Wittgenstein, Benjamin, Kaila ja Foucault suhtautuivat kuolemaan ja miten he kuolivat? Heijastaako filosofin tapa kuolla hänen käsitystään elämästä ja kuolemasta?

Causality and Mind presents seventeen of Nicholas Jolley's essays on early modern philosophy, which focus on two main themes. One theme is the continuing debate over the nature of causality in the period from Descartes to Hume. Jolley shows that, despite his revolutionary stance, Descartes did no serious re-thinking about causality; it was left to his unorthodox disciple Malebranche to argue that there is no place for natural causality in the new mechanistic picture of the physical world. Several essays explore critical reactions to Malebranche's occasionalism in the writings of Leibniz, Berkeley, and Hume, and show how in their different ways Leibniz and Hume respond to Malebranche by re-instating the traditional view that science is the search for causes. A second theme of the volume is the set of issues posed by Descartes' innovations in the philosophy of mind. It is argued that Malebranche is once again a pivotal figure. In opposition to Descartes Malebranche insists that ideas, the objects of thought, are not psychological but abstract entities; he thus opposes Descartes' 'dustbin theory of the mind'. Malebranche also challenges Descartes' assumption that intentionality is a mark of the mental and his commitment to the superiority of self-knowledge over knowledge of body. Other essays discuss the debate over innate ideas, Locke's polemics against Descartes' theory of mind, and the issue of Leibniz's phenomenalism. A major aim of the volume is to show that philosophers in the period are systematic critics of their contemporaries and predecessors

G. W. Leibnizin mielenfilosofiassa ymmärrykselle on jatkuvasti läsnä erilaisia taipumuksia erilaisiin päämääriin. Nämä taipumukset tai syyt toimia jollakin tavoin saattavat perustua selviin ja tarkkoihin havaintoihin ja olla tiedostettuja ennakkotahtomuksia. Näiden lisäksi mielessämme on epälukuinen määrä epäselviin havaintoihin perustuvia tiedostamattomia ja hetkittäisiä passioita, oikkuja tai hurahduksia. Kun henkilö ryhtyy harkitsemaan toimintaansa, nämä erilaiset taipumukset ja ennakkotahtomukset alkavat ottaa mittaa toisistaan. Prosessin tuloksena on lopullinen tahtomus tai riittävä syy. Kun ymmärrys on muodostanut suosituksen, tahto seuraa Leibnizin mukaan sitä ja toteuttaa ao. toiminnan. Ideaalitapauksessa ymmärryksen suositus on optimi näistä eri suuntiin johtavista syistä. Tavallisesti kyseessä on kuitenkin kompromissi, joka johtuu epäselvien havaintojen häiritsevästä vaikutuksesta harkintaan. Mitä paremmin ymmärrys toimii ja mitä tarkempia havainnot ovat, sen parempi on ymmärryksen toimintasuositus ja sita vahvemmalla ovat selvän ja tarkan joukkue epäselvän joukkuetta vastaan. Kuvaan esitelmässäni ylläolevan tilanteen ja tarkastelen tapoja, jolla agentti voi vaikuttaa toimintaansa. Vertailen myös pikaisesti Hobbesin ja Leibnizin näkemyksiä riittävästä syystä.

will give an overview of the fascinating communication between G. W. Leibniz and Pierre Bayle on pre-established harmony and sudden change in the soul which started from Bayle’s footnote H to the article “Rorarius” in his Dictionnaire historique et critique (1697) and ended in 1706 with Bayle’s death. I will compare the views presented in the communication to Leibniz’s reflections on the soul in his partly concurrent Nouveaux essais sur l’entendement humain (1704) and argue that many topics in the communication with Bayle are discussed with more details in Nouveaux essais. I also argue that the communication helped Leibniz to respond to Locke’s views concerning uneasiness in An Essay Concerning Human Understanding, II, xxi. Bayle himself, however, was not able to completely understand Leibniz’s views on spontaneity as he was unaware of the contents of the Nouveaux essais, especially the systematic role of petites perceptions in Leibniz’s philosophy of mind. I will also reflect on whether the controversy could have ended in agreement if it would have continued longer.

According to Leibniz, there is no death in the sense that the human being or animal is destroyed completely. This is due to his metaphysical pluralism which would suffer if the number of substances decreased. While animals transform into other animals after “death”, human beings are rewarded or punished of their behavior in this life. This paper presents a comprehensive account of how Leibniz thought the “death” to take place and discusses his often unclear views on the life after death. I will also present a new, naturalistic reading of Leibniz’s views on afterlife.

Descartes argued that the passions of the soul were immediately felt in the body, as the animal spirits, affected by the movement of the pineal gland, spread through the body. In Leibniz the effect of emotions in the body is a different question as he did not allow the direct interaction between the mind and the body, although maintaining a psychophysical parallelism between them. -/- In general, he avoids discussing emotions in bodily terms, saying that general inclinations, passions, pleasures and pains belong only to the mind or to the soul (NE II, xxi, §72). He is also keen to point out that our passions derive mostly from our bodies. However, like Spinoza (Ethics III, prop. XI, Scholium) he thought that some emotions such as joy can produce pleasures which can be described also in bodily terms. For example, in a short memoir Felicity he says that music can be a pleasure for the ears and symmetry can be a pleasure for the eyes. These more intellectual emotions are actions in the sense that they represent perfection emanating from their source, the absolutely perfect being, that is, God. The feeling of perfection may produce a state of well-being which concerns both the soul and the body. -/- In my paper I will trace instances of Leibniz’s remarks on how these kind of emotions affect the body. I will also discuss the different ways the body gives rise to passions in the soul. My primary source is Nouveaux essais, book II, chapter xx and xxi, but I will also discuss various other writings by Leibniz.

Artikkelissaan ”The Balance of Reason” Marcelo Dascal on osoittanut, että metafora syiden punnitsemisesta järjen vaa’assa on yleinen Leibnizin kirjoituksissa ja sitä on pidettävä hänen yleisenä järkeilyn metodinaan tilanteissa, joissa ei voida suorittaa täydellistä loogista analyysiä. Keskustelen tässä esitelmässä tuosta metaforasta ja ehdotan Jaakko Hintikan ja Simo Knuuttilan aiempien esityksien pohjalle rakentaen, että käsityksissään ihmisen praktisesta rationaalisuudesta Leibniz sovelsi myös toista melko tuntemattomaksi jäänyttä heuristista päätöksentekomallia, joka liittyy hänen työhönsä luonnonfilosofiassa ja mielenfilosofiassa, ja jota hän sovelsi tapauksissa joissa päätökseen vaikuttavat arvot ovat toisiaan täydentäviä. Tämä moniarvoisuuden huomioon ottava malli edustaa uudenlaista ja modernia ajattelua moraalifilosofian historiassa.
