How do we measure fitness of a technology startup as a function of time/stage? Rapid positive changes in fitness would be considered value inflection points.

Also, rapid changes in fitness due to new entrants can be easily detected. For example, in the Three Little Pigs story, the appearance of the wolf impacts fitness distribution and as a result changes ROI of house-construction tech.

The word ‘_perceive_’ is, in our common usage, shot through and through
with the notion of cognitive apprehension. So is the word
‘_apprehension_’, even with the adjective _cognitive_ omitted. I will
use the word ‘_prehension_’ for _uncognitive apprehension_: by this I
mean _apprehension_ which may or or may not be cognitive.

Whitehead. Science..., 1925.

If we modeled this prehension as a CT monad we could develop and algebra of prehension, with quantative thresholds that separate the uncognitive and cognitive.

X -> [W, WxY]

Here the operation [W, Wx(-)) is the monad on the type system which is induced by the above adjunction; and this latter function is naturally regarded as a morphism in the Kleisli category of this monad.

The great characteristic of the mathematical mind is its capacity for
dealing with abstractions; and for eliciting from them clear-cut
demonstrative trains of reasoning, entirely satisfactory so long as it
is those abstractions which you want to think about. The enormous
success of the scientific abstractions, yielding on the one hand
_matter_ with its _simple location_ in space and time, and on the other
hand _mind_, perceiving, suffering, reasoning, but not interfering, has
foisted onto philosophy the task of accepting them as the most concrete
rendering of fact.

Thereby, modern philosophy has been ruined.

Apart from recurrence, knowledge would be impossible; for nothing could
be referred to our past experience. Also, apart from some regularity of
recurrence, measurement would be impossible. In our experience, as we
gain the idea of exactness, recurrence is fundamental.

Classification is a halfway house between the immediate concreteness of
the individual thing and the complete abstraction of mathematical
notions. The species take account of the specific character, and the
genera of the generic character. But in the procedure of relating
mathematical notions to the facts of nature, by counting, by
measurement, and by geometrical relations, and by types of order, the
rational contemplation is lifted from the incomplete abstractions
involved in definite species and genera, to the complete, abstractions
of mathematics. Classification is necessary. But unless you can progress
from classification to mathematics, your reasoning will not take you
very far.

The practical counsel to be derived from Pythagoras, is to measure, and thus
to express quality in terms of numerically determined quantity. But the
biological sciences, then and till our own time, have been
overwhelmingly classificatory. Accordingly, Aristotle by his Logic
throws the emphasis on classification. The popularity of Aristotelian
Logic retarded the advance of physical science throughout the Middle
Ages.

It often happens, therefore, that in criticising a learned book of
applied mathematics, or a memoir, one’s whole trouble is with the first
chapter, or even with the first page. For it is there, at the very
outset, where the author will probably be found to slip in his
assumptions. Farther, the trouble is not with what the author does say,
but with what he does not say. Also it is not with what he knows he has
assumed, but with what he has unconsciously assumed. We do not doubt the
author’s honesty. It is his perspicacity which we are criticising. Each
generation criticises the unconscious assumptions made by its parents.
It may assent to them, but it brings them out in the open.

...thought can penetrate into every occasion of fact, so that by comprehending its key conditions, the whole complex of its pattern of conditions lies open before it.
...
Pythagoras was the first man who had any grasp of the full sweep of this general principle.
...
He asked, ‘What is the status of mathematical entities, such as numbers for example, in the realm of things?’ The number ‘two,’ for example, is in some sense exempt from the flux of time and the necessity of position in space. Yet it is involved in the real world. The same considerations apply to geometrical notions—to circular shape, for example.
...
unless you can progress from classification to mathematics, your reasoning will not take you very far.

Accordingly the full universe, disclosed for every variety of experience, is a universe in which every detail enters into its proper relationship with the immediate occasion. The generality of mathematics is the most complete generality consistent with the community of occasions which constitutes our metaphysical situation.

This is a really deep point. Of all the sciences, math is the most internally consistent world: all the way from the most abstract generalizations down to humdrum elementary school arithmetics.

Schopenhauer ventures into math and concludes that space begets geometry, while time begets algebra. He also trashes Euclides theoretical approach; i'll update the post with some quotes later.

«Мифы составляют, говоря буквально, наиболее драгоценное сокровище племени. Они относятся к самой сердцевине того, что племя почитает как святыню. Наиболее важные мифы известны лишь старикам, которые ретиво оберегают их тайну... Старые хранители этих тайных знаний сидят в селении, немы, как сфин- ксы, и решают, в какой мере они могут, не навлекая опасности, доверить знания предков молодому поколению и в какой именно момент эта передача тайн может оказаться наиболее плодотворной...» (Леви-Брюль 262). Мифы — не только составные части жизни, они — части каждого человека в отдельности. Отнять у него рассказ — эти значит отнять у него жизнь.
...
Лишившись мифов, племя было бы не в состоянии удержать свое существование.

...начало этого процесса, процесса перерождения мифа в сказку, сказывается в откреплении сюжета и акта рассказывания от ритуала. ^Момент этого открепления от обряда есть начало истории сказки, тогда как ее синкретизм с обрядом представляет собой ее доисторию.
...
Связь этих обрядов с мифами и связь их обоих со сказкой еще совершенно не исследована.
...
- Из всего сказанного видно, что уже очень рано начинается «профанация» священного сюжета (под «профанацией» понимаем превращение священного рассказа в профанный, т. е. не духовный, не эсотеричёский, а художественный). Это и есть момент рождения собственно сказки. Но отделить, где кончается священный рассказ и начинается сказка, — невозможно.

-- В. Пропп. Исторические корни волшебной сказки.


Rituals recreate myths and give rise to stories, which in turn lead to literature and, in the case of Ancient Greece, result in philosophy. Alternatively or, most likely coincidently, in Ancient Egypt and Babylon, myth and rituals give rise to astrology and mathematics.

“Cultural representations such as Little Red Riding Hood, the Golden Rule, or multiplication tables are, most of the time, considered in the abstract, even though they must be instantiated in mental and public representations in order to play a role in human affairs.. Since representations are recognized in our commonsense ontology, the question arises: What cognitive mechanisms do we have, if any, for drawing inferences about them? ”

“There must be a mindreading module—actually a minds-reading module, with “minds” in the plural—that has the job of managing, in our mental files about other people, what these people have in their men “mental files. No such module, however, could do the job on its own. In order to perform mindreading inferences about the inferences that are performed in other people’s mind, the mindreading module must be linked to a great variety of other inferential modules and use them for updating the information represented in individual files.”

Dan Sperber. “The Enigma of Reason: A New Theory of Human Understanding.”


Fairy tales make mind reading easy. The most popular ones ensure that we know what's on the character' mind at any given time.

upd. actually, it's even more interesting than that. The concept of proof invented by the Greeks, also facilitates mind reading.

...inasmuch as philosophy
is to be
science,
it cannot
borrow its method
from a subordinate science,
such as
mathematics...

On the contrary,
it can only be
the nature
of the content

which is responsible for
movement
in scientific knowledge,

for it is the content’s
own reflection
that first
posits and generates
what that content is.

“IV. (9) 

The understanding 
                   forms positive ideas 
              before 
                  forming negative ideas.

V. (108:10) 

It perceives things not so much under the condition
   of duration as under a certain form of eternity, and in an
   infinite number; or rather in perceiving things it does not
   consider either their number or duration, whereas, in imagining
   them, it perceives them in a determinate number, duration, and quantity.”

По моему скромному опыту, хороших школьных учителей математики очень мало, гораздо меньше, чем хороших учителей других предметов. Интересно, как можно было бы проверить эту гипотезу и обнаружить возможные причины?

В университетах хороших преподавателей математики гораздо больше. Тоже интересно, почему?

We start the video with a joke but later he talks about the difference in modes of explanation and gives a nice illustration how a detailed correct explanation subtracts from understanding, rather than adding to it. Relevance is key.



He also talks about the role of machines (i.e. technology) in philosophy:
