My fields of interest essentially encompass the history of modern philosophical thought (17^th and 18^thcenturies) and the philosophy of art and aesthetics, from the 18^th century to the present. My research subjects can be grouped into four themes.

1. The first - and the most important in my past work - concerns the reconstruction of the main issues in 18^th-century philosophical aesthetics. My initial university studies focused largely on the role of aesthetics in Kantian philosophy and the German Aufklärung; I then expanded my analysis to include the French, English and Scottish Enlightenment. Among the questions that interest me in this context are the birth of a specific philosophical discourse on art in the 18^th century; the nature of aesthetic experience and critical judgment; the relationships between ethics and aesthetics; the relationships between passions and artistic experience; the status of fiction; models for explaining invention and creativity; the explanation of paradoxical emotions; and theories of tragic emotion.
    
2. A second research theme concerns the problem of affectivity in modern philosophy and, in particular, the issue of the role of intersubjectivity in the engenderment and communication of passions. To study this question so obviously neglected by historians of the philosophical theories of passions, I start from the "model" of sympathy developed by David Hume and Adam Smith, to inventory the different philosophical explanations of passional life, from Spinoza to Rousseau, and examine their ethical and aesthetic implications.
    
3. I am also interested in the use of fictions in philosophical discourse. I study the rich and diversified use that classical and Enlightenment philosophers make of experiences of thought, of epistemological fictions and fictional and rhetorical devices in discourses aimed at producing truth.
    
4. Lastly, I have undertaken research that should lead, with the collaboration of my colleagues, to the publication and annotation of a selection of major philosophical texts by certain members of the "speculative philosophy" class of the Berlin Academy, including Johann Georg Sulzer and Jean Bernard Merian. Halfway between Leibnizianism and empiricism, the debates of the Berlin Academy, between 1748 and 1780, are an ideal laboratory for following the transformation of the key issues in the philosophical thought of the Enlightenment on the nature of knowledge, representation, action, feelings, etc.
