The purpose of this paper is to examine the ateleological moment of learning through imitation. In general, we can learn something new through imitating models we are given, which embody the values of our own society, culture and institutions. This means that imitation is understood in terms of the representation or reproduction of original models. In this understanding of imitation, however, the creative aspect of imitation is missed. In relation to this I shall, first, consider learning through imitation in terms of Walter Benjamin's theory of mimesis discussed in his essay, "On the Mimetic Faculty." It begins by examining general understanding of the concepts of experience and writing. Second and third, while reconsidering the idea of imitation, I shall bring out the difference between mimesis and copying, based on Plato and Aristotle, and I shall examine the former, especially its involuntary aspect. Fourth, in order to consider the ateleological moment of learning through imitation as mimesis, I discuss the relation between mimesis and the chance event. Fifth, Benjamin's allegorical "anti-autobiography" entitled "A Berlin Childhood around 1900," which ponders the idea of childhood as otherness is considered in order to explore what is happening in the very moment of writing, driven by the chance event. To conclude, I shall show how the very moment of writing involves an unceasing transformation of the self.
