This article discusses Du Châtelet’s challenging claim that entertaining illusions, especially illusions of being esteemed by posterity, is conducive to happiness. It does so by taking a contextualizing approach, contrasting her views with some Epicurean aspects of the views on illusions and happiness in Bernard de Fontenelle and Julien Offray de La Mettrie. I will argue for three claims: (1) Du Châtelet’s comparison between self-related illusions and illusions in the theater is vulnerable to objections deriving from some distinctions that Fontenelle’s (...) poetics draws between the role of illusions in the theater and the role of illusions in real life. (2) Examining Fontenelle’s analysis of the detrimental effects of self-related illusions indicates several respects in which Du Châtelet has underestimated the ambivalent nature of illusions. (3) Du Châtelet’s view that illusions are akin to sensations that are favorable to us problematically generalizes La Mettrie’s insight that some acts of the imagination have a quasi-perceptual nature.

I investigate Du Châtelet's contribution to the concept of time and position the relevance and content of that contribution between Leibniz and Kant. I argue that Du Châtelet advances Leibniz's concept of time by explaining how we form the idea of time in our mind and how time as an ideal being relates to succession in real beings. I show that Du Châtelet, differently to Kant, recognizes the dependency of time in its constitution on succession in "real things" and that (...) her concept of time is in this respect superior to Kant's. With a detailed investigation into Du Châtelet's notion of time in its own right and without prematurely "fitting" it into a defined debate between her contemporaries, I am aiming to reveal her original contribution to an understanding of time. I locate her concept of time in a context that is explicitly philosophical in terms of an investigation into how the idea of time is formed and constituted rather than a physical debate on the nature of time as a phenomenon relating to the movement of bodies.
