 Some of the most original insights provided by what has also been characterized as “early phenomenology” concern the notion of intentionality, which is the property of some mental states whereby they are directed towards objects and states of affairs. Several members of the Munich and Göttingen circles claimed that there are radically different kinds of intentionality (and, by extension, of intentional acts), which cannot be reduced to a unitary genus. Moreover, these authors fostered our understanding of various forms of intersubjective intentionality by developing insightful theories about social or speech acts, empathy, and collective intentionality.
