Could there possibly be an edge to existence itself.

Sounds a tad masochistic...

Let me put the question another way, Fresco. Are you a dualist, a monist, or something else?

One member is a non-dualist constructivist

Lets start your labels. There seems to be ...a school drop-out, a street wise ex-bar tender, an amateur intellectual reactionary, a skilled cutter and paster, an obsessive-compulsive,.......anything to add ?

Wait a minute...that first one just texted me to say that he follows Wittgenstein's view that there is no such thing as "private language", so the label "solipsist" is ridiculous.

Of all philosophical positions and forms of speculation known to mankind, solipsism is perhaps the most extreme and paradoxical. The remarkable thing about affirming the existence of the solus ipse as the only known and testable instance and source of existence for the universe is that this affirmation seems to be reached as an extreme logical conclusion of both idealism and empiricism, two otherwise irreconcilable doctrines of thought.

There are few, if any, consistent doctrinaire solipsists in the Western tradition. The best known instances of solipsistic talk (not always accepted as such) are given by George Berkeley and, closer to our days, by Husserl and Wittgenstein.

Solipsism as qualifier is, in philosophical parlance, an insult, and even the suspicion of flirting with it stigmatises one with ignominious guilt. As a consequence, a philosopher contaminated by it, however slightly, will retreat into philosophically more sound positions by trying to deploy his own kind of realism, phenomenological (cum corpore, cum conscientia),transcendental, communicational, empirical, dialectic, scholastic, etc....

The laconic dictum, ‘esse est aut percipi aut percipere,’ [to be is to be perceived (or to perceive)] which summarises the impossible central solipsistic position,...nevertheless haunted several powerful and critical minds, among whom Fichte, Wittgenstein, and Husserl, let alone Husserl’s, progeny: Sartre and Merleau-Ponty.

If you've got anything original to say about "existence" please do. In short Put Up or Shut Up.
