The following passage from Biosemiotics by Jesper Hoffmeyer (page 53-54) ... — Janus
...is pretty unreliable.
:)
The way I would look at it is that purpose and form are tied together by what, in modern physics, has become enshrined as the principle of least action. So when Nature has a purpose - an intent to be expressed in an action - there is an optimisation where the shortest path is the one chosen.
This is actually a really mysterious fact - or at least it requires spooky nonlocality because it means that nature picks out the most effective path having considered absolutely every available possibility.
So folk like Aristotle, Plato and Peirce looked at nature and could see something like this at work. Causation involves the holistic settling on some generalised optimal balance.
Plato made finality part of his world of forms. The idea of the good was the light that illuminated all the more particular forms. So goodness - as another way of getting at optimality, balance, effectiveness - was the ultimate purpose of existence. That was the telos.
Aristotle then made the distinction between final and formal cause more explicit. Finality spoke to generality - pure purpose, but now in all its manifest variety - while form became the explicitly particular - and now included the accidents of substance. Instead of one goal, goal-centredness became a thing. And formal cause became - in my view - over-identified with whatever the heck shape something wound up taking.
The idea of necessary form (that which serves the purpose) and accidental form (that which is only purposeful in the sense it doesn't actively prevent the said purpose being achieved) got confused.
Peirce then did take a fully constraints-based/hierarchical view of causation and so had a sufficiently complex model of reality to separate the necessary from the accidental (when it comes to the third thing of the actual).
And then while he stressed "irreversibilty" - a tellic trend in nature - it wasn't about the universal growth of accidents or randomness, but the exact opposite. The purpose of the Cosmos was the universal growth of reasonableness or orderly intelligibility. It was the growth of habits - the constraints that suppress randomness and chaos.
So there are differences and similarities. I prefer to focus on the similarities. What all these guys saw was that there is some kind of holism going on, some kind of downward acting oversight, which causes the Cosmos, the physical world, to be organised by a global optimising principle. The forms that matter take are intelligible because nature can check every possible option to find the most locally effective choice to actualise.
Now this is unmysterious when we think about it as evolution or development. It seems every possibility is being actualised and then either promoted or erased. We can see the optimisation in action.
But current physics - not yet having that kind of "four causes" holism when it comes to picture of reality - is still stuck with a rather hand-waving story on how nature actually implements its least action principle in practice.
With quantum theory for instance, we know that a path integral or sum over histories formalism works. The calculations are correct to umpteen decimal places. But how nature knows to try every path and actualise only the most optimal path (on average - this is a probabilistic story with quantum physics) is the weird and non-local hole in the theory as yet.
Final cause is traditionally understood to be synonymous with final purpose. How can we relate the ideas of "randomness" and "irreversibility" to the idea of 'purpose'? — Janus
Again, purpose does align with irreversibility. It says things are heading towards some end because they are moving away from some beginning. And right from the beginning, they were already headed in that direction.
But Peirce definitely didn't think randomness was the final desire. It was instead the chaotic beginning that reasonableness would leave behind by imposing its logical habits of order.
And even the Heat Death of the Universe can be understood as a state of maximal order, minimal chaos. (Entropy counting is a trickier concept than folk usually realise here.)
The Eastern idea of Karma is often explained as the idea of "cause and effect". Can the idea of Karma be related to the idea of the four causes? — Janus
I think it is related but different.
Eastern philosophy stresses equilibrium balance. So it is a picture of fluctuations or striving settling back towards stillness.
And again this is quite a naturalistic picture. You find it in the organicism of Anaximander or Heraclitus. The only surviving fragment of actual writing from Anaximander is a rather enigmatic comment about cosmic injustices becoming balanced.
So he had a developmental model of the Cosmos - the creation of worlds by the separation of the pure potential of the Apeiron into the hot and the cold, thence the dry and the moist. But this was a Karmic model also in that there was nothing standing in the way of all the separated apeiron simply folding back into itself and returning to its initial untroubled state. Disturbances might erupt - like turbulence in a stream - and then just as easily vanish.
This was also the Buddhist doctrine of dependent co-arising. It is the reason for a cyclic view. Stuff can bubble up and organise to have complex form. But that kind of symmetry-breaking seems perfectly reversible. There is no reason it should persist, except by accident, or because we falsely try to maintain it.
So you have two contrasting metaphysics - even though both are broadly organic and holistic.
And I, of course, find the fact that there is this dichotomy of choices only what one would expect. The actual whole story is triadic. So the equilibrium story, and the tellic story, are like the synchronic and diachronic views of the one metaphysics.
This indeed fits very nicely with the Big Bang/Heat Death cosmology of modern physics. As I mentioned about counting entropy, a problem is that from one point of view, the total entropy of the universe has never changed. It may have cooled, yet it has also expanded. So one thing has been exchanged for another, without changing the sum total.
So from a cross-sectional perspective, the universe is always in thermal equilibrium (if we forget the tiny fraction that is negentropic matter for the moment). But from a longitudinal perspective, the universe is transforming from a chaotic fluctuating beginning to a big silent nothingness of minimal fluctuation.
To sum up, the ancients did look at nature and did see a holistic story. But it gets confusing as there is then a tendency to latch onto one or other of a pair of dichotomous alternatives. Either existence is basically eternal and unchanging - so any eruptions of busy striving will be something temporary, and bound to get cancelled out. Or it is basically striving and transformative - and so there is some actual one-way journey that starts in chaos and winds up in some kind of intelligible perfection (like our good selves even
:) ).
Peirce is the modern metaphysician who finally set out a larger framework - a tradic or hierarchical one - that could incorporate these two alternatives. It could be both a story of holistic equilibrium and a story of a natural growth of purposeful form.
But that kind of ninja metaphysics is hard to wrap your thinking around. Hoffmeyer and his fellow Euro-semioticians are a fine bunch, but they come at semiotics from a broadly linguistic angle. What is central to them is the code duality - the symbol~matter aspect of the story.
The biosemioticians who best understood Peirce - in my view - were those in the US who were the pioneers in applying hierarchy theory to biological science. They were looking at things structurally. So they could recognise straight away how semiotics mapped to that kind of triadic complexity - the kind which is built of pairs of dichotomies, the kind that has both a cross-sectional metaphysics and also an "exactly opposite" longitudinal one.
