[3] Hopkins is best known for his work on Husserl and Jacob Klein, although he has also published on Plato,[4][5] Kant,[6] Heidegger,[7] and Derrida.

Hopkins's general argument is that Heidegger's hermeneutical critique of Husserl's reflective phenomenology of consciousness presupposes the structures of Husserl's phenomenology that are the targets of that critique.

It does so by challenging their common claim that Husserl's is historically determined by the limits of Greek ontology and metaphysics.

[10] His 2011 book, The Origin of the Logic of Symbolic Mathematics: Edmund Husserl and Jacob Klein,[12] compares Klein's largely overlooked Greek Mathematics and the Origin of Algebra (1934 and 1936) with Husserl's concern to provide a philosophical foundation for the formalization of logic and mathematics.
