Being textual includes innumerable elements and aspects. Each and every form of text and text in that form of literature embraces and consists of its own individual and personal characteristics; these may include its personality, the individuality of that personality, the popularity, and so on. The textualities of the text define its characteristics. However, the characteristics are also closely associated with the structure of the text (Structuralism). Peter Barry's discussion of textuality notes that "its essence is the belief that things cannot be understood in isolation – they have to be seen in the context of the larger structures they are part of". To form an opinion, criticise, or completely interpret a text one would first have to read the complete literary work as a whole; this enables the reader to make supported judgements on the personality and individuality of the text. The text is always hiding something. Although the reading may define and the interpretation may decide, the text does not define or decide. The text rests as operationally and fundamentally indecidable. Roger Webster frequently uses metaphors of ‘weaving’, ‘tissue’, ‘texture’, ‘strands’, and ‘filiation’ when talking about the structure of texts. He also agrees that "instead, the text is a surface over which the reader can range in any number of ways that the text permits."
