The Stoics on Impulses, Passions, and Disappearance of Reason - PDF-PowerPoint which I used on 9th May 2024 for the online lecture held at the 8th INTERNATIONAL TRANSDISCIPLINARY SYMPOSIUM BIOETHICS AND APORIA OF PSYCHE, Faculty of Philosophy and Religious Studies, University of Zagreb, Zagreb, 9–10 Mai 2024. I am working on a text corresponding to the PowerPoint. In my inquiry, I shall analyse the Stoic notion of impulse and of passion: the main interest of the study will be dedicated to the Stoic description of the progressive disappearance of reason due to the corresponding progressive domination of negative passions. My investigation will deal with the process of the emergence of the impulses, with the role of the assent to the impulses and with the formation of the passions. The connection of the false assent to the formation of the passions, the influence of the opinion on the false assent, and the consequent dominance of the passions within the soul will be analysed. The centre of the exposition will be represented by the loss of any power formerly possessed by reason: the dominance of the passions in the individual’s soul brings about the complete collapse of reason. I shall then inquire into the difference between negative passions and positive passions. The cognitivist positions of the Stoics and the instruments of liberation from the passions will belong to my study.
