'Truth and Content'


“Aboutness” is a grand-sounding name for something basically familiar. Books are on topics; portraits are of people; the 1812 Overture concerns the Battle of Borodino. Aboutness is the relation that meaningful items bear to whatever it is that they are on, or of, or that they address or concern.

Brentano made aboutness the defining feature of the mental. Phenomenologists have studied the aboutness-features of particular mental states. Materialists have sought to ground it in teleology or natural regularities. Attempts have even been made, in library science and the theory of information, to operationalize aboutness.

Materialists have sought to ground it in teleology or natural regularities. Attempts have even been made, in library science and the theory of information, to operationalize aboutness.


And yet the notion plays no serious role in philosophical semantics. This is surprising — sentences have aboutness properties, if anything does. One leading theory gives the meaning of a sentence by listing the scenarios in which it is true, or false. Nothing is said about the principle of selection, about how and why the sentence would be true, or false, in those scenarios. Subject matter is the missing link here. A sentence is true because of how matters stand where its subject matter is concerned.

I will be asking, first, how we might go about making subject matter a separate factor in sentence meaning/content, and second, what “directed contents” can do for us in other parts of philosophy.

Trinity Term 2011

John Cooper, (Princeton)

'Ancient Greek Philosophies as a Way of Life' 

The 2011 John Locke Lectures


Philosophy is a demanding intellectual discipline, with many facets: logic, epistemology, philosophy of nature and science, metaphysics, ethics, political philosophy, philosophy of art, rhetoric, philosophy of language and mind. But a long tradition of ancient Greek philosophers, beginning with Socrates, made their philosophies also complete ways of life. For them reason, perfected by philosophy—not religion, not cultural traditions and practices—constitutes the only legitimate authority for determining how one ought to live. They also thought philosophically informed reason should be the basis for all our practical attitudes, all our decisions, and in fact the whole of our lives. In these lectures we examine the development of this pagan tradition in philosophy, from its establishment by Socrates, through Plato and Aristotle, the Stoics, Epicurus, the Pyrrhonian Skeptics, and Plotinus and late ancient Platonism.

The 2011 John Locke Lecture series was held at 5 p.m. on Wednesdays in weeks 1 to 6 of Trinity Term 2011. The lectures were given at the Gulbenkian Lecture Theatre, St Cross Building, Manor Road. The classes took place at the Faculty of Philosophy, 10 Merton Street.

Trinity Term 2010

Professor David Chalmers (ANU)

'Constructing the World'

John Locke Lecture


In Der Logische Aufbau Der Welt, Carnap argued that all truths are definitionally entailed by a very limited class of truths. Most philosophers think that the project of the Aufbau is a failure and that nothing like it can succeed. I will investigate the prospects for an Aufbau-like project, centering around what I call the Scrutability Thesis: all truths are a priori entailed by a very limited class of truths. I will also discuss applications to Carnapian projects in epistemology, the philosophy of language and mind, metaphysics, the philosophy of science, and metaphilosophy.

The lectures took place on Wednesdays, Weeks 2 to 7, of Trinity Term 2010. They started at 5pm, and took place at the Gulbenkian Theatre, St Cross Building, Manor Road.

Trinity 2009

Thomas M. Scanlon (Alford Professor of Natural Religion, Moral Philosophy, and Civil Polity, Harvard) 

'Being Realistic about Reasons'

Abstract: The idea that there are irreducibly normative truths about reasons for action, which we can discover by thinking carefully about reasons in the usual way, has been thought to be subject to three kinds of objections: metaphysical, epistemological, and motivational or, as I would prefer to say, practical. Metaphysical objections claim that a belief in irreducibly normative truths would commit us to facts or entities that would be metaphysically odd—incompatible, it is sometimes said, with a scientific view of the world. Epistemological objections maintain that if there were such truths we would have not way of knowing what they are: we could “get in touch with” them only through some strange kind of intuition. Practical objections maintain that if conclusions about what we have reason to do were simply beliefs in a kind of fact, they could not have the practical significance that reasons are commonly supposed to have. This is often put by saying that beliefs alone cannot motivate an agent to act, but it is better put as the claim that beliefs cannot explain action, or make acting rational or irrational in the way that accepting conclusions about reasons is normally thought to do.

I will argue that all of these objections are mistaken. The idea that there are truths about are reasons for action does face serious problems. But these are normative problems—problems internal to the normative domain, whose solutions, if there are such, must themselves be normative.

The lectures took place on Wednesdays, Weeks 1 to 5, of Trinity Term 2009. They started at 5pm, and took place at the Gulbenkian Theatre, St Cross Building, Manor Road.
