1. Can philosophy “communicate” with others? The question is badly put. The point is not for philosophy to “teach” or “communicate” anything to, e.g., science. Philosophy does not “inform” or even “critique” science. Philosophy opens science. Yet is not philosophy also a deductive, axiomatic structure (i.e., a totality)? Can philosophy thus open itself? Is this not the ethical imperative of reflection (as a colleague of mine says)? Has not this reflection and this opening onto thinking (the thinking of the infinite) been at the heart of philosophy since Socrates? Socratic philosophy has never been, primarily, about “critiquing” or “negating” or even “changing” the world. Philosophy has always been positive, creative of new worlds, other worlds (“otherworldly resonances”).
2. If philosophy is the presentation of what happens or what does not happen, the relevant difference between philosophy and art is that art is precisely irrelevant to what does or does not happen.
3. If I say “Plato” should be treated as a big text composed of his (individual) texts, and thus that Platonic philosophy is fidelity to his concepts—this is a descriptive-normative conception of philosophy. A philosophy that treats the text otherwise can certainly do so, but is this not a naïve philosophy, since the former is the condition of possibility for the latter (naïve) philosophy?
And yet, we face again the problem of the limit: naïveté can never be revealed to itself.
