Wittgenstein's - Tractatus

Apparently, Wittgenstein walked away from philosophy after publication of the Tractatus. He thought he had solved the problems of philosophy, logic and reality.

In trying to ‘see’ Hodges’ model, in mathematical terms, there may be lessons in Wittegenstein’s approach, both in content and style. Of course, as a non-mathematician, I probably should leave well-alone; and stick to nursing. But that is the problem: from 1987-88 there is a need for a different perspective, even if this is a personal challenge. As with many ‘reviews’ here, we can look at Wittengenstein’s work, reflect upon it, and consider how it relates to the purposes, structures and content of Hodges’ model.

The Tractatus’s first line then, offers a warm welcome.

‘The world is everything that is the case.’ [I]

Making the decision to become a nurse and enrolling as a student makes you an educational and workforce demographic case.

Once a student in the university lecture theatre, you hopefully whether consciously, or not are exposed to the theory – practice gap; as you yearn to be on your first placement. Now it you who is seeking ‘cases’. As we live, and statistics roll and tally, the question of caseness (and categories) is key, one that is carried around even if not always active, recognised as such.

As noted in the previous post, we can for Hodges’ model (and other models, frameworks it must be said) think of ‘case’ as a, or the situation. 

A mathematical approach to Hodges’ model involves looking at things, concepts, people as objects. This includes patients and carers. In terms of a project worthy of pursuing in nursing and other disciplines involved in healthcare, this mathematization presents a non-trivial challenge. A fully-deserved response would be: 'What have you done to the aptitude for care and caring attitude? You've cancelled - subtracted it!' Humour aside:

'In order to know an object, I must know not its external but all its internal qualities.' [2.01231] 

Is this equivalent to us getting to know our patient / client and their socio-political context? 

‘The way in which objects hang together in the atomic fact is the structure of the atomic fact.’ [2.032] 

It is a help that Wittgenstein points to structure (crumbs of understanding are welcome here, as incremental steps). In formulating Hodges’ model we first identify the axes. It is the axes that then provide a space, four domains in total, to frame the objects that we decide; or, as the situation dictates, what concepts are placed in the domains of Hodges' model.

There is a successive series that follows, combining place, space and logic: ‘The proposition determines a place in logical space: the existence of this logical place is guaranteed by the existence of the constituent parts alone, by the existence of the significant proposition.’ [3.4]

‘The propositional sign and the logical coordinates : that is the logical place.’ [3.41]

‘The geometrical and the logical place agree in that each is the possibility of an existence.’ [3.411]

‘Although a proposition may only determine one place in logical space, the whole logical space must already be given by it.
(Otherwise denial, the logical sum, the logical product. etc., would always introduce new elements -in co-ordination.) 
(The logical scaffolding round the picture determines the logical space. The proposition reaches through the whole logical space.)' [3.42]

While Wittgenstein came to view ‘the picture theory of meaning’ as incorrect, as a conceptual framework and diagrammatic resource Hodges’ model is closely tied to this form of representation.

Of course, the logic at work here, is far from mathematical, but there is surely a logic.

'Formal concepts cannot, like proper concepts, be presented by a function.' [4.126]

'There is therefore really a sense in which in philosophy we can talk of a non-psychological I.
The I occurs in philosophy through the fact that the "world is my world'".
The philosophical I is not the man, not the human body or the human soul of which psychology treats, but the metaphysical subject, the limit - not a part of the world.' [5.641] 

'Although the spots in our picture are geometrical figures, geometry can obviously say nothing about their actual form and position. But the network is purely geometrical, and all its properties can be given a priori.

Laws, like the law of causation, etc., treat of the network and not of what the network describes.' [6.35]

There is much more in this work, and much that remains a challenge. Many commentators have written and said in interviews that the Tractatus rewards re-reading and some sentences stay with you for life (The Great Philosophers BBC TV). 

I'm still seeking mine.

v WCCS26: World Conference on Complex Systems 20-22nd April

Day 2 Tuesday 21st April (Revisiting) Keynote Speaker: Abderrazak El Albani - 
Emergence of Intercellular Cooperation: At the Origins of Eukaryotic Complexity
Session Chair: Khawla Tadist

This keynote was fasacinating. As I begin this post on the 100th birthday of Sir David Attenborough, who would have us all see life in the broadest terms, value life and diverse habits, and Earth as our collective and shared home.

Abderrazak El Albani explained the search for LUCA the last universal common ancestor - 3.8 billion years ago. Many dates in the emergence story of humanity, have been progressively pushed back. The first fire, art, languages, our co-habitation and intimate relationships with Neanderthals.

In healthcare, as a practitioner you have to be aware of your scope of practice. At WCCS, scale (as in iv) was ever present across research in complexity, and complex systems. Not just physical size nano-to-mega but temporal too, as we journeyed billions of years. Several of the slides are presented here:

https://www.synchrotron-soleil.fr/en/news/discovery-oldest-macroscopic-planktonic-eukaryotes-contribution-nanoscopium-beamline (with a reference).

There is a video (French): https://www.youtube.com/watch?v=bh3t26cU7xc

I asked a question, which may have been psychological preparation for own presentation to follow. Listening, I could see how the work Abderrazak El Albani and his team are doing, could be readily translated to the search for life on Mars. There has been a 'routine' interchange of planetary material between Earth and Mars over the aeons. Fitting surely that the sedimentary rocks sought lie in  A key lesson, is that light helps us see, but not all lights are equal. Light sources brighter than the sun become incredible scientific instruments. The longevity of the dinosaurs was highlighted, at least 140 million years. There is no comparison with homo sapiens then, even as those dates have been pushed further back in time. Time defeated me as I tried to make the observation that even the dinosaurs did not make it to their first galactic birthday (c.250 million years - and what a carousel). I like the thought (slide) of 'Earth as Memory'. 

What really counted was the expressed concern about what is happening now: in the Anthropocene.

The second keynote:
Nigel Gilbert - Policy in a Complex World: Towards Complexity-Aware Policymaking
Session Chair: Ali Idri 

Was helpful to me, as the dated conundrum of benefits realisation from our technologies, and evidence-based policy still leaves a gap (for me) within the POLITICAL care/knowledge domain of Hodges' model. The illustration/graphic elements of Prof. Gilbert's slides were a brilliant complement to the content:

Prof. Nigel Gilbert - WCCS26 21st April

I wonder if within policy the constant in the equation is continuity and as a quantity it is an unknown? This seems to the case in health policy, across successive governments. You may (also) find this chart informative: https://www.cecan.ac.uk/news/the-visual-representation-of-complexity/

Perhaps, a key factor in complexity is the fact that nothing stays the same, so continuity is nuanced? Michael Quinn Patton's book Developmental Evaluation was noted re. learning while doing. Now I wish I'd held on to Qualitative Research & Evaluation Methods (4th ed.). The discussion of 'obesity system map' and 'whole systems analysis' was appreciated here.*

Since Marrakech and WCCS, I've noticed acknowledgement in the literature that 'research' is currently flooded with AI tools. I'm sure PRSM Participatory System Mapper is a welcome addition, (as noted in iv) tools to facilitate participation are much needed:

Collaborative Creativity

The Participatory System Mapper (PRSM) is an app that makes it easy to draw networks (or 'maps') of systems, working together collaboratively.'

I will definitely check this resource out; and CECAN. After Prof. Gilbert, the next Track included my contribution, which I will return to. Rather distracted, I have a somewhat blurred slide, with: 'The global tensor of educational research is' then headed 'Learning poverty. Being unable to read and understsand a simple text; with points 1-4.'. I'm not sure which presentation this was, but zeroed in on the literacy theme, and the word tensor. Another slide refers to '6. Topological substitution for Success'. I think it is (writing this is helping recall!):

Harvey Spencer Sánchez-Restrepo, Jorge Louçã, Martha Belén Carmona-Soto and Sofialeticia Morales-Garza
Topological Patterns of Academic Success: Insights from Complex Network Analysis

'Always Label Your Axes' - Zazzle.

Before that there was another model, as the next keynote speaker: Chris Bauch demonstrated during the conference wearing a t-shirt:
