Idealism/realism: A metaphysical distinction?

In this article, I intend to show, first of all, that the metaphysical neutrality of the Logical Investigations leads to untenable consequences and even threatens the coherence of Husserl's project. In truth, Husserl's distinction between phenomenology and metaphysics and its corollary, the pure and simple exclusion of metaphysical problems - such as that of the reality of the so-called external world - from the field of nascent phenomenology, make it impossible to give a satisfactory form to a problem as central to this new discipline as that of perception. However, my final word will not be on the indissoluble link between the problems that phenomenology poses for itself and those that Husserl would like to be able to “purify” it from the outset. However permeable the boundaries between these two general research directions may be, phenomenology and metaphysics are not equivalent. Phenomenology can even be said to contribute to formulating and solving certain metaphysical problems, starting with the idealism/realism antithesis. It is to this contribution that I will devote the second part of these reflections.
