In Husserl's phenomenology, phenomenological cognition is to be accomplished only when what is seen in the phenomenological reduction becomes expressed in language and described. The aim of this paper is to understand what phenomenological description really is, by discussing the general relationship between 'seeing' and 'expressing'. The research begins with a clarification of the general relationship between 'intuition' and 'expression' as elucidated in Husserl's texts. The author will then try to discuss the relationship between phenomenological intuition and its expression, a relationship which Husserl scarcely considered (Ⅱ). This discussion will lead to a revelation of the function of metaphorical expression in phenomenological description (Ⅲ). Finally, the author will give a clear if paradoxical depiction of phenomenological description of the ultimate and deepest constituting dimension, which would be the final aim of phenomenology.
