*Philosophy of Science Colloquium TALK: James Glover (IVC Fellow)*
Ramsey's Theories (1929)
Philosophy of Science Colloquium
The Institute Vienna Circle holds a Philosophy of Science Colloquium
with talks by our present fellows.
*Date:* 20/11/2025
*Time:*16h45
*Venue:*New Institute Building (NIG), Universitätsstraße 7, 1010 Wien, HS 2i
*Abstract:*
My talk concerns Frank Ramsey’s theory of theories. The literature on
his paper ‘Theories’ (1929) has tended to argue that the
primary-secondary systems model of theories that it presents is (i) such
that ‘the primary’ refers to what is given in experience while the
‘secondary’ refers to theoretical concepts that are not so given, and
(ii) anti-reductionist about those theoretical concepts. I show instead
that the primary-secondary systems model is (i) defined along
explanatory lines (though it may derivatively apply to the distinction
between what is given and what is not) and (ii) reductionist about
theoretical concepts. Along the way, I trace some seldom-noted
influences on the paper from Wittgenstein, Hilbert, Weyl, and Carnap. I
then connect Ramsey’s theory of theories to his late epistemological and
meta-philosophical views, and argue that they exhibit an interesting
degree of agreement with those set out in Carnap’s /Aufbau/. I conclude
that Ramsey’s late views spanning the philosophy of science,
epistemology and meta-philosophy were more continuous with the
scientific philosophy of the Vienna Circle than has been appreciated.
