It is the aim of this paper to develop the phenomenology of phronesis through a phenomenological interpretation of Aristotle’s theory of phronesis by employing different kinds of phenomenological reductions. In section 1, I will show that phenomenological reduction is identical with a change of attitude and that we have to employ different kinds of phenomenological reductions in order to interpret Aristotle’s theory of phronesis phenomenologically. In section 2, employing different kinds of phenomenological reductions, I will attempt to develop the phenomenological psychology of phronesis through a phenomenological interpretation of Aristotle’s theory of phronesis. In section 3, employing different kinds of intersubjective reductions, I will clarify intersubjective aspects of phronesis. In section 4, adopting these insights, I will try to resolve two of the many difficulties of Aristotle’s theory of phronesis. In section 5, I will conclude with two remarks concerning the future tasks of the phenomenology of phronesis.
