    Why Essences: Spinoza
    In Matias Kimi Slavov & Jan Forsman (eds.), Contemporary Perspectives and Historical Dimensions: Festschrift in Honor of Jani Hakkarainen, Tampere University. pp. 236-251. 2025.
    This essay attempts to answer a simple but largely neglected elemental question: why does Spinoza endorse essences? I begin by delineating three perennial metaphysical problems, namely those of individuation, change, and persistence, after which I analyze the way in which they function as the deeply ingrained backdrop that motivates Spinoza’s essentialism, allowing him to develop a sophisticated conceptual framework on which he builds his ethics proper. I end by discussing the relationship betwe…Read more

    This essay offers an in-depth reading of the geometrical illustration of Ethics IIP8S and shows how it can be used to explicate the whole architecture of Spinoza’s system by specifying the way in which all the key structural features of his basic ontology find their analogies in the example. The illustration can also throw light on Spinoza’s ontology of finite things and inform us about what is at stake when we form universal ideas. In general, my reading of IIP8S thus elucidates what it means, …Read more

    In this paper I argue that, contrary to what one might think, early modern rationalism displays an increasing and well-grounded sensitivity to certain metaphysical questions substantial form was designed to answer—despite the fact that the notion itself was in such disrepute, and emphatically banished from natural philosophy. This main thesis is established by examining the thought of Descartes, Spinoza, and Leibniz through the framework constituted by what have been designated as the two aspect…Read more

    This paper argues that what interests Locke most is not whether we are free to suspend desire but the nature of the liberty that suspension grants us, and that Lockean liberty is essentially about deliberation that takes place in what has nowadays come to be called the space of reasons. This allows me to offer a novel and balanced account that carefully designates both causal and rational elements of Locke’s theory of moral agency: after having reached judgment concerning the best course of acti…Read more

    Leibniz on Possibilia, Creation, and the Reality of Essences
    with Peter Myrdal and Arto Repo
    Philosophers' Imprint 23 (17): 1-18. 2023.
    This paper reconsiders Leibniz’s conception of the nature of possible things and offers a novel interpretation of the actualization of possible substances. This requires analyzing a largely neglected notion, the reality of individual essences. Thus far scholars have tended to construe essences as representational items in God’s intellect. We acknowledge that finite essences have being in the divine intellect but insist that they are also grounded in the infinite essence of God, as limitations of…Read more

    Elämän käsite Spinozan filosofiassa

    [The title in English: "The Concept of Life in Spinoza's Philosophy."] Tarkastelen tässä kirjoituksessa elämän käsitteen merkitystä Spinozan filosofian eri vaiheissa, ja selvitän, miksi käsitteellä ei enää hänen Etiikkansa ontologiassa ole keskeistä asemaa. Samalla piirtyy esiin joitakin Spinozan ajattelun olennaisia aspekteja.

    Häpeän filosofiasta
    In Jyrki Korkeila, Kaisla Joutsenniemi, Eila Sailas & Jorma Oksanen (eds.), Irti häpeäleimasta, Duodecim. pp. 54-62. 2011.
    [The title in English: "On the Philosophy of Shame."] Viimeaikaisessa filosofianhistoriallisessa tutkimuksessa on kiinnitetty yhä enemmän huomiota siihen, että ainakin osa tunteistamme on muuttunut historian saatossa. Lieneekin ilmeistä, että tunne-elämämme on merkittävässä määrin erilaista kuin esimerkiksi voimakkaasti kristinuskon leimaamalla keskiajalla. Toisinaan näkee väitettävän, että myös suhteemme häpeään olisi muuttunut varsin radikaalisti tai että se olisi jopa kokonaan kadonnut esimer…Read more

    Genealogia historiallisena ontologiana. Foucault’n suhteesta Nietzscheen ja hermeneutiikkaan
    In Sakari Ollitervo, Jussi Parikka & Timo Väntsi (eds.), Kohtaamisia ajassa. Kulttuurihistoria ja tulkinnan teoria, University of Turku. pp. 110-135. 2003.
    [The title in English: "Genealogy as Historical Ontology: On Foucault's Relationship to Nietzsche and Hermeneutics."] Foucault’n genealogiaa voidaan luonnehtia olemistamme konstituoivien valta–tieto-verkostojen määrittämien käytäntöjen historiallisen polveutumisen analyysiksi. Kysyn artikkelissani, miten Foucault’n genealogia määrittyy suhteessa Friedrich Nietzschen (1844–1900) ajatteluun ja hermeneuttiseen käsitykseen tulkinnasta. Tähän vastatakseni aloitan tarkastelemalla genealogian perusteit…Read more

    In this paper, I examine some main philosophical positions taken in the admittedly multifarious discussion concerning the possibility of rational evaluation in comparing different forms of life. Most importantly, I will outline a view of rational evaluation that would be as sensitive as possible to the diversity and offerings of various cultural viewpoints.

    Theory of Conatus
    In Andre Santos Campos (ed.), Spinoza: Basic Concepts, Imprint Academic. pp. 95-105. 2015.
    In this essay, I will begin by delineating the context of the conatus principle, after which I will provide a reading of the two propositions (EIIIP6 and P7) that contain the very core of the theory. This in turn will enable me to explain how Spinoza’s theory of conatus is connected to his views on desire, activity, and teleology.

    Spinoza on Virtue and Eternity
    In Matthew J. Kisner & Andrew Youpa (eds.), Essays on Spinoza's Ethical Theory, Oxford University Press. 2014.
    The goal of this essay is twofold. First, I will explicate the dynamic nature of Spinoza’s doctrine of virtue by discerning his reasons for defining virtuousness in terms of active power. Second, by taking this understanding of virtue as the point of departure, I will suggest a sense in which we can be said to be more or less eternal to the extent that we are virtuous and active. Spinoza’s specific brand of essentialism underpins both his doctrine of virtue and that of eternity, and reaching the…Read more

    In addition to the notion of power (potentia), Spinoza employs the notion of power of acting (agendi potentia), especially in the Ethics. This raises the question, if Spinoza uses both ‘power’ and ‘power of acting’, what is the difference between the two? What else could power be, for Spinoza, but power of acting? What is the relationship between power and activity in his system? This essays aims at giving answers to these questions; thereby emerges what may be called an actualist model of God’s…Read more

    Spinoza on Activity in Sense Perception
    In Jose Filipe Silva & Mikko Yrjönsuuri (eds.), Active Perception in the History of Philosophy: From Plato to Modern Philosophy, Springer. pp. 241-254. 2014.
    There can be little disagreement about whether ideas of sense perception are, for Spinoza, to be classed as passions or actions—the former is obviously the correct answer. All this, however, does not mean that sense perception would be, for Spinoza, completely passive. In this essay I argue argues that there is in the Ethics an elaborate—and to my knowledge previously unacknowledged—line of reasoning according to which sense perception of finite things never fails to contain a definite active co…Read more

    Spinoza’s Essentialism in the Short Treatise
    In Yitzhak Y. Melamed (ed.), The Young Spinoza: A Metaphysician in the Making, Oxford University Press. 2015.
    This essay traces the rather consistent essentialist thread that runs through the whole Short Treatise. This allows us not only to better understand the work itself but also to obtain a firmer grasp of the nature of Spinoza’s entire philosophical enterprise. In many ways, the essentialism we find in the Short Treatise is in line with Spinoza’s mature thought; but there are also significant differences, and discerning them throws light on the development of Spinoza’s philosophy.

    This chapter takes a fresh look at 3d2 of Spinoza’s Ethics, an absolutely pivotal definition for the ethical theory that ensues. According to it, “we act when something happens, in us or outside us, of which we are the adequate cause,” whereas we are passive “when something happens in us, or something follows from our nature, of which we are only a partial cause.” The definition of activity has puzzled scholars: how can we be an adequate, i.e. complete, cause of an effect outside us (which clear…Read more

    The Young Spinoza on Scepticism, Truth, and Method
    Canadian Journal of Philosophy 50 (1): 130-142. 2020.
    This paper offers a new interpretation of the young Spinoza’s method of distinguishing the true ideas from the false, which shows that his answer to the sceptic is not a failure. This method combines analysis and synthesis as follows: if we can say of the object of an idea which simple things underlie it, how it can be constructed out of simple elements, and what properties it has after it has been produced, doubt concerning the object simply makes no sense. The paper also suggests a way in whic…Read more

    Why Virtue Is not Quite Enough: Descartes on Attaining Happiness
    Archiv für Geschichte der Philosophie 103 (1): 54-69. 2021.
    Descartes explicitly states that virtue is sufficient for attaining happiness. In this paper I argue that, within the framework he develops, this is not exactly true: more than virtuous action is needed to secure happiness. I begin by analyzing, in Section 2, the Cartesian notion of virtue in order to show the way in which it closely connects to what, for Descartes, forms the very essence of morality – the correct use of our free will. Section 3, in turn, discusses Descartes’s view of happiness …Read more

    Schopenhauer’s Twofold Dynamism
    In Juhani Pietarinen & Valtteri Viljanen (eds.), The World as Active Power: Studies in the History of European Reason, Brill. pp. 305-330. 2009.
    Even if we grant that the concept of force has an important place in Schopenhauer’s view of natural sciences and that we definitely should avoid treating Schopenhauer’s theory of the will as a scientific hypothesis, it still does not follow that dynamic concepts would not be of utmost importance for metaphysics as Schopenhauer conceives it. A careful analysis that takes into account the context provided by early modern thinkers reveals that Schopenhauer’s system is based on an elaborate theory i…Read more

    Spinoza’s Essentialist Model of Causation
    Inquiry: An Interdisciplinary Journal of Philosophy 51 (4): 412-437. 2008.
    Spinoza is most often seen as a stern advocate of mechanistic efficient causation, but examining his philosophy in relation to the Aristotelian tradition reveals this view to be misleading: some key passages of the Ethics resemble so much what Suárez writes about emanation that it is most natural to situate Spinoza's theory of causation not in the context of the mechanical sciences but in that of a late scholastic doctrine of the emanative causality of the formal cause; as taking a look at the s…Read more

    Spinoza’s Geometry of Power
    Cambridge University Press. 2011.
    This work examines the unique way in which Benedict de Spinoza combines two significant philosophical principles: that real existence requires causal power and that geometrical objects display exceptionally clearly how things have properties in virtue of their essences. Valtteri Viljanen argues that underlying Spinoza's psychology and ethics is a compelling metaphysical theory according to which each and every genuine thing is an entity of power endowed with an internal structure akin to that of…Read more

    Kant on Moral Agency: Beyond the Incorporation Thesis
    Kant Studien 111 (3): 423-444. 2020.
    This paper aims to discern the limits of the highly influential Incorporation Thesis to give proper weight to our sensuous side in Kant’s theory of moral action. I first examine the view of the faculties underpinning the theory, which allows me to outline the passage from natural to rational action. This enables me to designate the factors involved in actual human agency and thereby to show that, contrary to what the Incorporation Thesis may tempt one to believe, we do not always act on maxims. …Read more

    Spinoza’s Ontology
    In Olli Koistinen (ed.), The Cambridge Companion to Spinoza's Ethics, Cambridge University Press. 2009.
    In this essay, I present the basics of Spinoza’s ontology and attempt to go some distance toward clarifying its most pertinent problems. I start by considering the relationship between the concepts of substance and mode; my aim is to show that despite his somewhat peculiar vocabulary there is much here that we should find rather familiar and intelligible, as Spinoza’s understanding of these matters harks back to the traditional distinction of substance and accident, or thing and property. After …Read more
