Pluralitas non est ponenda sine necessitate

——————————————-

Le rasoir d’Ockham ou rasoir d’Occam est un principe de raisonnement philosophique entrant dans les concepts de rationalisme et de nominalisme. Le terme vient de « raser » qui, en philosophie, signifie « éliminer des explications non nécessaires d’un phénomène » et du philosophe du XIVe siècle Guillaume d’Ockham.

Également appelé principe de simplicité, principe d’économie ou principe de parcimonie (en latin « lex parsimoniae »), il dispose d’une ancienne formulation :

    Pluralitas non est ponenda sine necessitate

    (les multiples ne doivent pas être utilisés sans nécessité)

Dans le langage courant, le rasoir d’Ockham pourrait s’exprimer par les phrases : « L’explication la plus simple est généralement la bonne », ou : « Pourquoi faire compliqué quand on peut faire simple ? » Une formulation plus moderne est que « les hypothèses suffisantes les plus simples doivent être préférées (il faut et il suffit) ». C’est un des principes heuristiques fondamentaux en science, mais ce n’est ni un principe de départ ni un résultat scientifique.

Le principe fait appel à une simplicité en termes de nombre d’entités, de concepts ou d’hypothèses utilisés, et non en termes de complexité de leur combinaison, les deux se contredisant généralement : si vous avez une explication d’un phénomène par la combinaison de deux causes séparées, le principe incite à rechercher une cause unique plus profonde qui serait à l’origine des causes préalablement postulées, ce qui donnera finalement, en cas de succès, une construction plus complexe mais avec un nombre plus réduit d’hypothèses.

One of the interesting thoughts for me which pertains slightly to this blog relates to finding an internally consistent and comprehensive explanation as to the nature of the dreams I have had and which are archived in this blog. I would genuinely be interested to hear any explanation from the psychology / psychiatry profession which attempts to explain the scope of them. This specifically so given my prior training as a scientist and current life context as a relatively socially isolated retired person.

Those dreams which appear to point at previous incarnations can be discounted as merely dreams. There is no need to invoke the hypothesis of reincarnation. But saying things are just dreams is a bit of a handwaving dismissal. It is not entirely satisfactory.

Invocation of the single hypothesis of reincarnation renders explanation easier in context and does not require any complicated theorising as to just why or how come I dream about, inter alia, Buddhist themed, dreams. Inherent in this is a difficulty because it suggests that there needs to be some mechanism of transfer of memory between different lives, different incarnations. It raises the question as to what exactly is the nature of the “thing” which not only reincarnates but which is able to carry memory and recollection in the absence of a biological body. The neuroscientist is likely to prefer a brain and perhaps evolving synaptic scaffold construct to explain memory. Such a thing cannot exist beyond the soft wet matter of living humanity. There is no biological or biochemical hypothesis which can account for the notion of memory transfer between lives. The science fiction writer or scientifically inarticulate new-ager might say, “it is all in the DNA”.  If it were, it is not facile to explain how “Buddhist DNA” found its way to a small valley in the foothills of Snowdon. Yes my mother when tanned could pass for an Indian especially if she wore a bindi. But the DNA explanation does not really wash. My dad was ginger.

The easiest explanation is to blame an overactive imagination on my part which somehow breaks though during sleep. Perhaps there is a part of my deep sub-conscious which wants to be “special” and thereby invents some new DSM-5 type nocturnal mental disorder, the classification of which could be career enhancing for some psychologist or other. I have a form of delusional psychopathy which may or may not be common. After all who in their right mind would make dreams like mine public? Best kept secret to avoid public gaze. We can come up with the Whacko McNutjob persona.

The fact of the dreams and their recall are, at least to me, real. My speculation is that they are not “common or garden”.

This does not require the invocation of significance. I am just some bloke who happens to dream a lot. No biggie…

Provided that they are not significant there is no wider problem or issue.

If however we invoke, even tentatively, a putative wider significance, a gamut of implications might surface. A similarity to mystical vision and quasi-religious imagery can be drawn. In some circles that is significant in terms of context and perhaps faith. The follow on question might be, “why does someone who, was for a short while, deep in the UK based science community have such phenomena?”. This community being the self-assigned debunker of myths and pseudoscience. “Bah!!”

One could say that weird stuff happens, end of story. It  / he is just an anomaly.

The easiest hypothesis is that the hundreds of dreams archived here are all “just some shit that I made up”. The follow on to this is that I must therefore have at least some imagination and persistent inventiveness. One could counter with the deep philosophical argument, “you just can’t make shit like this up!” I am not sure as to what the motive might be for this inventiveness though others could speculate freely. Maybe I am simply an attention seeker. Maybe it is all some big game to make people question the extent and wider applicability of their self-diagnosed omniscience.

For me it is just habit. If I have a dream which I can recall and am lucid in, when I get up of a morning,  I type it up in Word.  I sometimes make a short note on a post it before typing. There are close to 100 dreams in 2025.

I personally have no strong need to pick an explanation and have that as a definite. A part of the art of dreaming is to enjoy the unknown and the partially or poorly explained.

I can see multiple implications which will almost certainly never manifest. Life circumstance does not support these weekly possible trajectories. There is nothing I can do about it.

I could say something groovy…

The coalescence of the dreaming onto and into the physical plane is not easy. Surprisingly little, though nascent in dreaming, makes it through into the “agreed” and “shared” physical plane realties.

He is just a feckless dreamer, head in the clouds…

Each of us make our own versions of reality not all of which are entirely apt.

A Fondness for Thought Experiments

I speculate that many like to “win” an argument and be “right”. Some dread being demonstrably wrong. But the diamond sutra advises against seeking the absolute…

Our schooling demands answers which correspond in alignment to the quasi-consensual mark scheme. I have seen “A” level students marked wrong because, even though their answer was correct and accurate {according to my expert opinion}, it did not comply with the dogmatic mark scheme prepared by the thought police. Straying from the agreed dogma yields a poor grade and can prohibit further education.

There is an ethos to conclude, to be right, and to want to know where one stands. People can seek certitude when in fact there is none. They may misconstrue adamant assertion with accuracy and broad applicability. In fact, over simplification can be very attractive. There is a bit of laziness. Many rely on the imagined omniscience of “they”. If the herd deems it so, then it must be. Individual thinking and the expression thereof can lead to prompt and irrevocable social isolation.

One of things, I like to do is to take some kind of conceptual framework and then apply it to my life, to see if there is any fit. I don’t do this in a quantitative way rather I try it on like a moccasin. If it appears to fit as a thought experiment, I note the fit and then like a child with a sandcastle rub it out. I am really not fussed if I am right or wrong, nor with the quality of fit. I am fluid and don’t need fixed descriptors nor to be corralled by a conceptual framework. I am mindful that were the outcomes of these experiments accurate and those within the framework aware of this, implications might follow. Some of these within the model could be wide ranging.

Some might find this annoying.

“Tell me the answer!!!”

I also like the idea of all or nothing situations in which there is no negotiable middle ground. Herein lies a problem. Whenever I mention that I do not negotiate people immediately see it as a negotiation strategy which it is not. I am not responsible for the perceptions and conclusions of others. If they like to interact transactionally via negotiation, they may transfer their preference onto their interpretation of me. They may see me through their lens, which may have aberration and distortion.

Which model, which thought experiment applies? The answer is quite a few.

It would be very easy to characterise me as a spendthrift quasi-functional alcoholic who threw it all away, and as a result is a socially isolated loser eking out his end of days in self-induced poor health.

This model has only a very local implication and using Occam’s razor, paraphrased:

Entia non sunt multiplicanda praeter necessitatem.

As a model which fits it is the simplest and the best.

Therefore all other models are speculations and by way of embellishment.

People like complexity and may not be satisfied, though it is possible to leave things here with this characterisation. My (our) physical plane life does not impinge beyond a small geographical radius and a set of healthcare professionals. I very rarely travel more than 35km in radius. I have only travelled more than 150km once in six years.

There is no need to invoke any other explanation. I have played with various alternatives.

This then is a nothing situation, a null, a default

There are various other interpretations which may be a tad more grandiose, but although there is a hint of applicability, they are inconsistent with observable circumstance. These interpretations may further be inconvenient. Any model must have use or else it cannot be tested thus a theoretical possibility remains speculation and likely to fade into the mist. There is no point developing a use-less model, when viewed from one angle. Inconvenience is also not a desired property of a model. This can lead to jettison.

Reductionist thinking can limit but it also simplifies.

The thought experiment in the absence of tangible and measurable data often leads back to the null or near null hypothesis, which is the safe conclusion.

We all often unconsciously apply the model or bias which suits us best, which is easiest for us to assimilate and has little inconvenient implication for us.
