"Phenomenologies are a major stream of philosophy. Our aim with this Handbook is to explore critically and reflexively the plurality of phenomenologies and their becoming in the context of Management and Organization Studies (MOS). We detail in the introduction the genealogy of the phenomenological moment and make a distinction between four streams of phenomenologies: phenomenology as a phenomenological moment, post-phenomenologies, ante-phenomenologies, and non-phenomenologies. Beyond many clichés about phenomenologies, we argue that phenomenologies cultivate critical perspectives, ontologies, and even, for some of them, metaphysics that make them particularly interwoven with other philosophical traditions. We draw implications for MOS as a field."--
