Psychoanalysis, as an approach to literary criticism, is the analysis of the subconscious mind of the author/characters in a literary work. Accordingly, it is an attempt to delve into the depth of the text to discover its various meaning levels, to analyse the causes and impulses of characters’ external/social behaviour, and, thereby, to interpret the work. The approach is mostly based on C. G. Jung’s model of psychoanalysis which holds that the subconscious mind is the source and origin of human’s (social) behaviour. The foundations of the model are subconscious mind and archetypes. Archetypes are the universal, primitive mental patterns and experiences inherited over generations and are latent in human’s inner mind. The most important archetypes are persona, shadow, hero, anima, animus, etc., which appear in conscious mind in different forms, and are represented and reflected in literary works. This article studies archetypes in W. Golding’s Lord of the Flies from the Jungian psychoanalytic view point. The analyses reveal that the tensions and abnormal social behaviour of characters, as representatives of modern man, originate from their psychological abnormality, which, in turn, represents social problems and disastrous life-conditions of modern man.
