And, I made it clear that the fact you can reduce something to a dichotomy doesn't mean it is useful to do so. And yes, we all know you think dichotomies are the basis of everything. Your endless nattering about it, however, is not proof or evidence, and once again you've tried to hijack the discussion so you can preach the gospel of dichotomies.
Yet again, the point was that metaphysics does reduce things to dichotomies, and yet not to monads. And those dichotomies have proved immensely useful as the basis of reality modelling.
It is not my obsessive idea but philosophy's eternal discovery.
I agree that much of western intellectual history has been about an attempt to go one better and reduce to monads.
Heraclitus said all is flux so Parmenides had to say all is stasis. Or at least that is how modern historians like to recreate the to and fro of greek philosophy. Likewise, the atomists said all was substance and Plato said all was form (except he didn't - there was also, dichotomistically, the chora).
Anyway, repeated attempts have resulted in repeated failure. Can you do any better?
Information theory would seem a successful example of modern monadism. It from bit. Wolfram's CAs. Tegmark's infinitude. There is a lot of triumphalism about these ideas. I'm surprised you don't cite actual current examples of monadism. And I would enjoy knocking them down if you did.
I know how distressed you usually are over the inadequacy of ad hominen arguments in the place of reasoned, referenced, debate, so you will be happy to be reminded that the views I put forward are as ancient as civilisation. And they are not a religious belief that is preached but a model of logic that can be backed up by argument and evidence.
The challenge remains. What is a single (monadic) philosophical principle that exists all on its own-some?
Not a triad. That is a hierarchy.
To remind you again of some of the classic dichotomies, they are local~global, discrete~continuous, stasis~flux, chance~necessity, matter~mind, substance~form, atom~void...the list just goes on.
Now where is the similar list of monadic philosophical concepts? That is your challenge.
Otherwise you have to accept dichotomies rule (symmetry breakings rule) and have to start considering why.
Anything less would indeed be faith-based. One would be left making statements unsupported by arguments and evidence.
