This article seeks to explore the metaphor 'darkness and light' and its relevance to education through hauntological study. It draws on the ideas of Derrida and Fisher to reveal that the metaphor functions in binary form and holds significations of truth, goodness and knowledge to subordinate oppositional ideas of darkness. Despite the everyday usage of this metaphor, the subordination of darkness is shown to be less positive than it would appear. Darkness and light also shows itself to be an archetypal metaphor, meaning that it is founded in our depth-experiences of the world and is applicable in many varied contexts, therefore granting it a power to remain in everyday usage. The archetypal nature of this metaphor is uncovered through its utilisation in Plato's 'Allegory of the Cave', thus opening a discussion about how it continues to haunt education today. Broadly, it is the faith in the supposed betterment available through education that is exposed. Finally, in a Derridean manner, this article explores how the metaphor of darkness and light could be overturned in relation to education, thus destabilising a foundational metaphor on which education currently lies.
