Helen Hattab

Associate Professor


I am an Associate Professor of Philosophy and expert in late Aristotelian and Early Modern Philosophy and Science.  I have published on the historic transformations that the metaphysical concepts of substance, form, matter and causation underwent in the 16th and 17th centuries.  I have worked most extensively on Descartes’ relation to his predecessors, but have come to focus more and more on the independent interest and merit of arguments on these issues found in competing atomist, naturalist, Platonic, Ramist and Stoic philosophies of this period. Concurrently I have been tracing the defenses and reinterpretations of key Aristotelian philosophical principles by their most influential proponents (e.g., Zabarella, Toledo, Fonseca, Suarez) to reveal how early modern Aristotelianism transformed itself from within.  One long-term research project concerns different senses of the twin methods of analysis and synthesis, and related issues surrounding scientific knowledge of universal attributes/common natures, discussed by16th and 17th logicians and metaphysicians. I am particularly interested in whether/how analysis and synthesis are at work in the ethical and political theories that Thomas Hobbes and Benedict de Spinoza developed in the second half of the 17th century. As part of this larger project, I am writing a book that traces debates about the metaphysical grounding of the universal concepts employed in scientific demonstrations from late 16th century Aristotelian philosophers to Spinoza.


I regularly teach History of Ancient and Medieval Philosophy, History of Seventeenth Century Philosophy and History of Eighteenth Century Philosophy as well as graduate seminars on various Scholastic Aristotelian and Early Modern philosophers.  Recent seminars have included readings from Avicenna, St Thomas Aquinas, John Duns Scotus, Francisco Suarez, Francis Bacon, René Descartes, Thomas Hobbes and Benedict de Spinoza.
