The thinking of the English school is often viewed as a middle ground between liberal and realist theories. Its theory involves the idea of a society of states existing at the international level. Hedley Bull, one of the core figures of the English school, agreed with the traditional theories that the international system was anarchic. However, he insisted that this does not imply there are no norms (expected behaviours), thus claiming there is a societal aspect to international politics. In this sense, states form an ‘Anarchical Society’ (Bull 1977) where a type of order does exist, based on shared norms and behaviours. Due to its central premise, the English school is often characterised as having an international society approach to IR. This describes a world that is not quite realist and not quite liberal – but rather a world that has elements of both.
Constructivism is another theory commonly viewed as a middle ground, but this time between mainstream theories and the critical theories that we will explore later. It also has some familial links with the English school. Unlike scholars from other perspectives, constructivists highlight the importance of values and shared interests between individuals who interact on the global stage. Alexander Wendt, a prominent constructivist, described the relationship between agents (individuals) and structures (such as the state) as one in which structures not only constrain agents but also construct their identities and interests. His famous phrase ‘anarchy is what states make of it’ (Wendt 1992) sums this up well. Another way to explain this, and to explain the core of constructivism, is that the essence of international relations exists in the interactions between people. After all, states do not interact; it is agents of those states, such as politicians and diplomats, who interact. As those interacting on the world stage have accepted international anarchy as the defining principle, it has become part of our reality. However, if anarchy is what we make of it, then different states can perceive anarchy differently and the qualities of anarchy can even change over time. International anarchy could even be replaced with a different system if a critical mass of other individuals (and by proxy the states they represent) accepted the idea. To understand constructivism is to understand that ideas, or ‘norms’ as they are often called, have power. IR is, then, a never-ending journey of change chronicling the accumulation of the accepted norms of the past and the emerging norms of the future. As such, constructivists seek to study this process.
