Upcoming events

Logic-related events in Fall 2022

November 3. 14-16, Helsinki Philosophy Colloquium: Øystein Linnebo, “Abstraction and Grounding: between Aristotle and Plato”. Main Building, U3039. Unioninkatu 34.

Abstract: Are there “thin objects” whose existence does not make any substantial demand on the world? In my Thin Objects (OUP 2018) I defend an affirmative answer based on a Fregean form of abstraction. This talk connects two central aspects of the resulting view with the notion of metaphysical grounding. First, every truth about some thin objects is grounded in a truth that does not involve these objects. Second, the notorious “bad company problem” for abstractionism can be solved by insisting that every truth about the desired abstracta be grounded in a truth that is solely about a prior and independently available ontology. I explain how the resulting view is a form of “soft platonism” with some broadly Aristotelian features.

Breaking the glass-ceiling: Gender in science and philosophy.

Over the last couple of decades the gender gap in academia has
significantly narrowed, yet the pace at which progress is taking place
is surprisingly slow. In philosophy, for example, it’s still very much
the case that while the proportions men and women are roughly equal
among undergraduate philosophy students, the number of men increases
disproportionally at the faculty level. Finnish academic philosophy is
no exception. What causes this gap to persist? Why do some fields fare
better than others? Which measures can we take to fill the gap? During
this event we bring together national and international experts to
address these and related questions with a particular focus on the
Finnish context.

The event will be held in Helsinki at Metsätalo, sali 1 / hall 1.
Entrance via Unioninkatu 40 or Fabianinkatu 39.
