We’re all familiar with the idea that philosophy operates at a level of discourse than which there is no higher, in some structural sense. What does this claim actually amount to?
First, a clarification: The idea I’m referring to doesn’t denigrate poetry, or fiction, or prayer, or paying compliments, or any other non-discursive uses of language. — J
Interesting discussion.
I certainly recognize that philosophers attempt to address everything and anything that was, is, will be, actually or potentially, in reality and in illusion, for all persons and other things, be they mindless or omniscient Gods or somethings else; and philosophy incorporates logic (math and language), poetry (aphorism), fiction (thought experiments), physical objects and theoretical impossibilities, and more in order to do its work. But that said, there is no need to think of any type of discourse as "higher" or "highest". I think such gradations may actually get in the way of what philosophers are trying to do (so all of the many philosophers in history who placed themselves above, instead of just apart, from the rest of us, were wrong). Philosophy, in a sense, is a leveler of discourse, always relentlessly sifting through the illusory for the reality and trying (mostly failing) to speak of the sifting; philosophy makes all discourse "discourse" and recognizes only a rankings like "valid or invalid" or "true and false".
The subject of the philosopher is everything, just like separately, the subject of the philosopher can instead be anything; but the subject of the philosopher is not just everything or anything over there, it is these things as they relate to or include the relator, the subjective experiencer; everything that is for me, with me, from me, and not for me, but moving away from me, from somewhere else - it is all of these at once that makes the topic of philosophy.
That said, philosophy is the science of scientific thought and language. It is a science. Reason or logical process is nearby, if not thoroughly infused within, every word of the philosopher. It is the discourse on discourse. It is the science of the self-aware being, being self-aware about scientizing.
Philosophy cracks open and destroys everything in its path, from Gods to atoms, in order to see if anything must remain bound, indestructible. It seeks to know what knowing knowledge means.
Philosophy is also born of love and desire, intention and focus, and is creative. This is to say, philosophy is one of the arts. (Maybe discourse on "art" is the highest discourse then?) The poet sees the meadow and builds something new out of it, with words, that can find their way into the minds and hearts of other people (other poets), so that something of the meadow and of the poet might now exist in the words and further in those who cannot see the meadow. Like the poet sees the meadow, the philosopher instead sees "seeing" or "being" or "minding" or "speaking" and builds something new out of it, with words, that can find their way into the minds and hearts of other people (other philosophers), so that something of this "being" or "minding" now exists in the words and further, in those who can only see for themselves.
The philosopher constructs, or creates, something new, in order to reveal to others for the first time in their lives, something that already is.
Philosophy is a doing, and not just the words that are constructed. Priests, poets, politicians, nearly all of us at some point, do philosophy during our lives. But the philosopher proper does philosophy on the philosophic itself; philosophizing is a self-aware activity (which is why it can be skeptical of its own existence).
The philosopher who speaks is conducting a never-ending test on speaking itself; they subject everything to such tests, such as what priests say when they say "God is one" and test what poets say when they say "we have the infinite within us" and test what politicians say when they say "This is the way forward, towards 'the good' and 'the just'." Philosophers must test every word of every sentence before they will say that something has been said at all. Philosophy is a testing (that is the science of it).
But if all of the content and art produced by the philosophers, all of their words, might be empty and hollow (still talking about "everything" as you can see), there is still great value in doing philosophy. Say what you will about the content of Plato, of Kant, of Nietzsche, of Buddha, of Heraclitus, of Wittgenstein, of Russell, of Derrida, of Aristotle, Lao Tsu, Descartes and Hegel..., in doing philosophy, we learn how to think. We learn how to recognize bullshit (illusion) faster. We learn to probe for our own biases and learn ways to shatter them as well as anything can be shattered. We practice logic. We practice clarity in discourse and precision in focus.
Philosophy is rarefied scientizing, in need of no matter, no particular clay, as it carves and molds nonetheless.
In the end, I would say that philosophy is only the highest discourse to those of us who have fallen in love with the mysteries of human experience - philosophy is the only activity, the only discourse, that might requite this love. Physics and biology may in the end satisfy this love, but it would still take the philosopher to notice our philosophy has been mistaken all along, so the philosopher would remain, abandoned and alone. "Desire is the cause of all suffering." So by some accounts, the lovers of wisdom, the philosophers, are the sowers of their own suffering. Seems undeniable, given that after 3,000 years of advances in the science of all things, we still can't say anything about everything.
