According to Alison Assiter, there are four common ideas regarding structuralism that form an ‘intellectual trend’. Firstly, the structure is what determines the position of each element of a whole. Secondly, structuralists believe that every system has a structure. Thirdly, structuralists are interested in ‘structural’ laws that deal with coexistence rather than changes. And finally structures are the ‘real things’ that lie beneath the surface or the appearance of meaning.
