existence and nothingness

Modern thought reduces existence to a series of appearances that reveal it. The purpose of doing so is to eliminate some of the dualisms that have put philosophers into trouble and replace them with phenomenal monism. Was this attempt successful?

We start from "appearance" and then propose two types of existence: in-itself and for-itself. What is the profound meaning of these two existences? Why do these two kinds of existence belong to ordinary existence? What is the meaning of this existence which contains within itself a completely separate realm of existence? If neither idealism nor realism can explain the relations that in fact serve to unify those realms that are indeed incommunicable, can we come up with any other solution to the problem? How can the existence of phenomena be transphenomenal?

It is to answer these questions that I wrote this book.
