  In the years since Husserl, Heidegger, et al. wrote, phenomenologists have dug into all these classical issues, including intentionality, temporal awareness, intersubjectivity, practical intentionality, and the social and linguistic contexts of human activity. Interpretation of historical texts by Husserl et al. has played a prominent role in this work, both because the texts are rich and difficult and because the historical dimension is itself part of the practice of continental European philosophy. Since the 1960s, philosophers trained in the methods of analytic philosophy have also dug into the foundations of phenomenology, with an eye to 20th century work in philosophy of logic, language, and mind.
