Ricoeur focuses on the importance of symbols and linguistics within hermeneutic phenomenology. For postmodernists, the hermeneutic circle is especially problematic. It is also evident in his own original contributions to hermeneutic and interpretive theory. Hans-Georg Gadamer expanded on these ideas of Heidegger and proposed a complete hermeneutic ontology. This further elaborates the idea of the hermeneutic circle. The reciprocity between text and context is part of what Heidegger called the hermeneutic circle. Traditionalists urged the rejection of this "new hermeneutic". This has been described by other thinkers as being hermeneutic reasonableness. Historically, three hermeneutic approaches have been used among Churches of Christ. Humanities are thus "doubly hermeneutic". In discovering the essence, however, the problem of the hermeneutic circle arises. Aldhelm wrote in elaborate, grandiloquent and very difficult Latin, known as hermeneutic style. Anthony Giddens calls this movement a double hermeneutic. When Barthes identifies an enigma in the text he marks it HER (short for hermeneutic). By contrast, the social sciences are engaged in the double hermeneutic.
