The recent debates about the nature of social freedom, understood in a broadly negative way, have generated three main views of the topic: these represent freedom respectively as non-limitation, non-interference and non-domination. The participants in these debates often go different ways, however, because they address different topics under common names, not because they hold different intuitions on common topics. Social freedom is sometimes understood as option-freedom, sometimes as agency-freedom and the different directions taken by the theories can often be explained by their addressing freedom in one sense, then in another. The non-limitation approach focuses primarily on option-freedom, the non-domination approach on agencyfreedom, whereas the representation of freedom as non-interference seems to spring from a failure to resolve the focus decisively on one target or another.

The rationality of individual agents is secured for the most part by their make-up or design. Some agents, however – in particular, human beings – rely on the intentional exercise of thinking or reasoning in order to promote their rationality further; this is the activity that is classically exemplified in Rodin’s sculpture of Le Penseur. Do group agents have to rely on reasoning in order to maintain a rational profile? Recent results in the theory of judgment aggregation show that under a range of plausible conditions they do. In a slogan: group agents are made, not born.

Philosophy invariably starts with the attempt to spell out ideas and beliefs that we already hold, whether on topics like time or causality, colour or value, consciousness or free will, democracy or justice or freedom. It may go well beyond such pre-philosophical assumptions in its further developments, regimenting them in unexpected ways, revising them on novel lines, even discarding them entirely in favour of other views. But philosophy always begins with the articulation of ordinary ideas and beliefs. This is where its ladder starts. As the name suggests, articulation requires that the ideas and beliefs articulated were already there waiting to be spelled out, and that identifying them is a matter of analysing..
