    Theological mysticism holds that there are certain aspects of God that are beyond human comprehension, and that our rational capacities can never truly understand. Such aspects would need to be merely accepted as features of the infinite divine nature, even if (or specifically if) they seem to contradict our rational understanding and logical analysis. In the early modern discussion, one of the most famous examples of theological mysticism is Descartes’s proclamation that even though God’s divin…Read more

    Margaret Cavendish on Dreaming
    Acta Philosophica Fennica 102. 2025.
    Margaret Cavendish’s (1623–1673) philosophy has been gaining increasing interest in recent years. Untypically to her time, she was a materialist, who denied the existence of immaterial substance. Deviating from other materialists of the period, like Thomas Hobbes (1588–1679), she likewise considered that matter was not in fact a ‘dead’ thing moved by external motion, but living, sensing, and thinking. Such curious commitments obviously raise questions about her views on human experience like per…Read more

    Émilie du Châtelet’n Vapaudesta 1700-luvun unohtuneena tekstinä
    In Sari Kivistö, Katariina Kärkelä, Erika Pihl & Isa Välimäki (eds.), Unohtuneet kirjoitukset: Katoaminen kirjallisuushistoriassa, Sks. pp. 229-251. 2025.
    Artikkeli tarkastelee Émilie du Châtelet’n vuonna 1737 kirjoittamaa ja pitkään unohduksissa ollutta käsikirjoitusta Vapaudesta (Sur/De la liberté), jonka Voltaire lähetti Preussin kruununprinssi Fredrikille omissa nimissään. Artikkeli rekonstruoi tekstin syntyhistorian, sen filosofiset ja poliittiset kontekstit sekä analysoivat sen tahdonvapauskäsitystä suhteessa aikakauden keskeisiin ajattelijoihin, kuten Christian Wolffiin, Leibniziin, Locke’en ja Samuel Clarkeen. Teksti puolustaa tahdon ja te…Read more

    At the beginning of the First Meditation, Descartes’s meditator considers not only the famous scenarios of dreaming and deceiver but also a third scenario: that she might be insane. This madness scenario is apparently rejected in favor of dreaming. I analyze the scenario of madness, drawing from Descartes’s comments about insanity as a medical condition, and compare it with the dreaming scenario. Overall, the scenario of madness has been generally neglected, receiving only minor discussion in th…Read more

    Émilie Du Châtelet on Freedom: The Wolffian Context
    with Jani I. Hakkarainen
    In Clara Carus & Jeffrey K. McDonough (eds.), Émilie Du Ch'telet in Relation to Leibniz and Wolff: Similarities and Differences, Springer Nature Switzerland. pp. 155-176. 2025.
    We contextualize Du Châtelet’s On Freedom (c. 1737) within the framework of Christian Wolff’s theory of free will and action. Wolff’s account resulted in a conflict with the German Pietists on whether internal spontaneity is central to free action, in its own right, or whether there needs to be some causal contribution from the will, independent of reason, to the action for that action to be free. Contextualizing Du Châtelet’s account with Wolff’s German Metaphysics (1719) and the ensuing Pietis…Read more

    Teresa’s Demons: Teresa of Ávila’s Influence on the Cartesian Skeptical Scenario of Demonic Deception
    Journal of the History of Women Philosophers and Scientists 2 (4): 25-45. 2023.
    Recent research in Baroque Scholastic and early modern meditational exercises has demonstrated similarity between Descartes’s Meditations and St. Teresa of Ávila’s El Castillo Interior. While there is growing agreement on the influence of Catholic meditations on Descartes, the extent of Teresa’s role is debated. Instead of discussing the full extent of Teresa’s influence, this paper concentrates on one example of the considered influence: the skeptical scenario of demonic deception, having clear…Read more

    I offer a novel reading in this dissertation of René Descartes’s (1596–1650) skepticism in his work Meditations on First Philosophy (1641–1642). I specifically aim to answer the following problem: How is Descartes’s skepticism to be read in accordance with the rest of his philosophy? This problem can be divided into two more general questions in Descartes scholarship: How is skepticism utilized in the Meditations, and what are its intentions and relation to the preceding philosophical tradition?…Read more

    Descartes and the Suspension of Judgment – Considerations of Cartesian Skepticism and Epoché
    Proceedings of the XXIII World Congress of Philosophy 70 15-20. 2018.
    In this paper I will argue how Descartes in the First and Second Meditation of the Meditations uses a very clear suspension of judgments or assent that in many ways resembles the epoché of the ancient skepticism, especially that of pyrrhonistic variant. First I show how the pyrrhonistic epoché works and what purpose it was used. After that I show how this Cartesian epoché both resembles and differs from the ancient epoché. My main argument is that Descartes, when using the method of doubt, doesn…Read more

    Can an Atheist Know that He Exists? Cogito, Mathematics, and God in Descartes’s Meditations
    International Journal for the Study of Skepticism 9 (2): 91-115. 2019.
    Descartes’s meditator thinks that if she does not know the existence of God, she cannot be fully certain of anything. This statement seems to contradict the cogito, according to which the existence of I is indubitable and therefore certain. Cannot an atheist be certain that he exists? Atheistic knowledge has been discussed almost exclusively in relation to mathematics, and the more interesting question of the atheist’s certainty of his existence has not received the attention it deserves. By exa…Read more

    Descartes on Will and Suspension of Judgment: Affectivity of the Reasons for Doubt
    In Gábor Boros, Judit Szalai & Oliver Toth (eds.), The Concept of Affectivity in Early Modern Philosophy, Eötvös Loránd University Press. pp. 38-58. 2017.
    In this paper, I join the so-called voluntarism debate on Descartes’s theory of will and judgment, arguing for an indirect doxastic voluntarism reading of Descartes, as opposed to a classic, or direct doxastic voluntarism. More specifically, I examine the question whether Descartes thinks the will can have a direct and full control over one’s suspension of judgment. Descartes was a doxastic voluntarist, maintaining that the will has some kind of control over one’s doxastic states, such as belief…Read more

    Artikkelissa otan kantaa niin sanottuun voluntarismikiistaan Descartesin tahdon käsitykseen ja arvostelmateoriaan liittyen kannattaen epäsuoraa voluntarismia. Käsittelen erityisesti kysymystä voiko tahdolla Descartesin mukaan olla suora kontrolli ihmisen arvostelmasta pidättäytymiseen? Pitkään vallassa olleen tulkintasuuntauksen mukaan Descartesin käsityksessä tahdolla on kyky vaikuttaa doksastisiin tiloihin suoraan, pelkällä tahdon aktilla. Tätä kutsutaan suoraksi voluntarismiksi ja se tarkoitt…Read more

    Mahdollisuus, välttämättömyys ja luodut ikuiset totuudet Descartesin filosofiassa
    In Ilkka Niiniluoto, Tuomas Tahko & Teemu Toppinen (eds.), Mahdollisuus, Philosophical Society of Finland. pp. 120-129. 2016.
    Tässä artikkelissa käsittelen Descartesin ikuisten totuuksien välttämättömyyteen liittyvää ongelmaa. Teoksessa Mietiskelyjä ensimmäisestä filosofiasta (1641–1642) Descartes nostaa esiin käsitteen ikuisista totuuksista, käyttäen esimerkkinään kolmiota. Kolmion muuttumattomaan ja ikuiseen luontoon kuuluu esimerkiksi, että sen kolme kulmaa ovat yhteenlaskettuna 180°. Se on totta kolmiosta, vaikka yhtään yksittäistä kolmiota ei olisi koskaan ollutkaan olemassa. Eräät ajattelemieni asioiden piirteet …Read more
