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.

Occam’s Razor and Past Life Recall

———————————————————-

Occam’s razor

In philosophy, Occam’s razor (also spelled Ockham’s razor or Ocham’s razor; Latin: novacula Occami) is the problem-solving principle that recommends searching for explanations constructed with the smallest possible set of elements. It is also known as the principle of parsimony or the law of parsimony (Latin: lex parsimoniae). Attributed to William of Ockham, a 14th-century English philosopher and theologian, it is frequently cited as Entia non sunt multiplicanda praeter necessitatem, which translates as “Entities must not be multiplied beyond necessity”, although Occam never used these exact words. Popularly, the principle is sometimes paraphrased as “of two competing theories, the simpler explanation of an entity is to be preferred.”

This philosophical razor advocates that when presented with competing hypotheses about the same prediction and both hypotheses have equal explanatory power, one should prefer the hypothesis that requires the fewest assumptions, and that this is not meant to be a way of choosing between hypotheses that make different predictions. Similarly, in science, Occam’s razor is used as an abductive heuristic in the development of theoretical models rather than as a rigorous arbiter between candidate models.

Last night we watched a 1997 film called “Contact” with Jodie Foster as the main protagonist among a {now} star studded cast. The special effects were naïve by todays’ standards. The film misused the notion of Occam’s Razor; the simplest explanation was that she did indeed travel to a civilisation near Vega. The film argued that this was too convoluted and did not happen whereas the counter explanation of cunning hoax which was way more convoluted and complicated was acceptable and true to the government. A simple inconvenient truth of interstellar travel was rejected in preference for a hyper-complicated adherence to what normal accepted, science and wisdom insisted.

Rules in science are kept, often way past their sell by date, exceptions and first, second and third order corrections terms are added, one must flog the life out of a dead horse rule. “Science” is so conservative that in worshipping at the temple it does not have to get called up to serve in the IDF. Elvis however did national service.

In the blog under the heading “Reincarnation Themed” in the column to the right are collected a number of dreams which are “Ronseal” dreams. A possible explanation is that elements of past life recall are implicated.

It might be possible to come up with some convoluted psychological hypothesis as to why I had these dreams, maybe invoke some DSM-5-TR defined criteria for some disorder or syndrome. It could be an act of creative writing on my part. I could have smoked way too many spliffs as a young man or simply be a tin-foil hat wearing rainbow unicorn jockey. I could be whacko the nut-job, from Loony-Ville Alabama.

The simplest explanation is that they contain elements of past life recall. Occam’s razor therefore suggests that this is more likely.

Unfortunately past life recall is not deemed possible by some.

If history teaches us anything it is that things deemed impossible, and adamantly so, can and do prove feasible. Once it was deemed mad to suggest Cholera was a water born disease. History suggests that the prevailing THEY are often wrong yet vehement and assertive. They refuse to accept that they could be in error. Power must not be yielded to plebs and upstarts.

The self-diagnosis by THEY of their own omniscience is rarely a sound diagnosis.
