Begriffe / Concepts:
(Z.B. reelle Zahlen, in ihrer Gesamtheit, sind nicht etwas, was real existiert, was man irgendwo vorfindet. Man konstruiert sie einfach.)
(Wir können einen Punkt, einen ausdehnungslosen "Körper", nicht eigentlich anschaulich wahrnehmen. Wir können ihn aber sehr wohl konstruieren.)
-----
According to Kant (?), concepts derive their content either from empirical intuition or from pure intuition, i.e. from formal construction in space and time.
(For example, real numbers, taken as a whole, are not something that really exists, something one might encounter somewhere. They are simply constructed.
We cannot actually perceive a point, an extensionless “body,” through intuition. But we can certainly construct it.)

Der Willensruck:
Betrachten wir zunächst die voll ausgebildeten Willenshandlungen, die eine regelrechte Vorperiode haben. Dann ist für den Willensruck die Abhebung gegenüber der Vorperiode wesentlich. Mögen seine Voraussetzungen auch in den Motivationsabläufen der Vorperiode liegen, er wächst nicht in gleitender Bewegung aus ihnen hervor, sondern springt aus ihnen heraus mit besonderer Deutlichkeit, wenn sich die Vorperiode in langen Kämpfen, Erwägungen und Zweifeln hingeschleppt hatte. Diese hören plötzlich auf, etwas Neues tritt ein - und damit wird das Gefühl der Unrast und Unsicherheit ersetzt durch ein Gefühl der Endgültigkeit, welches - trotz aller miterlebten Aktivität - doch etwas Ruhevolles hat. Diese retrospektive (nämlich vorangegangenen Kampf abschliessende) Seite des Willensrucks nennen wir "Entscheidung". (Genauer wäre "Selbstentscheidung"; denn es gibt auch Entscheidungen ohne eigenes Zutun; so wenn bei einem, vor der Berufswahl stehenden Knaben die verschiedenen sich kreuzenden Neigungen und Wünsche durch ein Machtwort des Vaters zum Abschluss gebracht werden).
Der Ausklang des Willensrucks endlich besteht darin, dass aus dem rein Psychischen (Entscheidung, Entschluss) ins Psychophysische übergegangen wird: dem Körper werden diejenigen Innervationen erteilt, welche die Handlung im Sinne des Entschlusses einleiten: "ImpuIs".<

Anspannung & Entspannung / Tension & Relaxation:
The art lies in regularly fostering tension, while at the same time not overstraining the bow. Whoever fosters periods of tension must also regularly plan for periods of relaxation:

Disziplin & Interesse:
-----
Verbale Stoffe sind in der Regel nicht sonderlich schwer verständlich, anders verhält es sich mit Stoffen aus der Mathematik oder den Computerwissenschaften: Hier kann man sich zwar vorübergehend Zeit nehmen und den subjektiv besonders interessanten Aspekten des Lernstoffs Aufmerksamkeit widmen. Darauf macht es aber Sinn, systematisch vorzugehen, und gerade mühsame und schwer verständliche Aspekte des Lernstoffs hochkonzentriert durchzukauen.

Selbststeuerung / Self-Control:
-----
The lay concept of self-control ultimately states that we can exert a certain guiding pressure on our thinking, perceiving, acting, and feeling. According to this concept, guilt is borne by those who fail to exert this pressure.

Pomodoro-Methode:
William James on Attention (II):
One often hears it said that genius is nothing but a power of sustained attention, and the popular impression probably prevails that men of genius are remarkable for their voluntary powers in this direction. But a little introspective observation will show any one that voluntary attention cannot be continuously sustained, — that it comes in beats. When we are studying an uninteresting subject, if our mind tends to wander, we have to bring back our attention every now and then by using distinct pulses of effort, which revivify the topic for a moment, the mind then running on for a certain number of seconds or minutes with spontaneous interest, until again some intercurrent idea captures it and takes it off. Then the processes of volitional recall must be repeated once more. Voluntary attention, in short, is only a momentary affair. The process, whatever it is, exhausts itself in the single act; and, unless the matter is then taken in hand by some trace of interest inherent in the subject, the mind fails to follow it at all. The sustained attention of the genius, sticking to his subject for hours together, is for the most part of the passive sort. The minds of geniuses are full of copious and original associations. The subject of thought, once started, develops all sorts of fascinating consequences. The attention is led along one of these to another in the most interesting manner, and the attention never once tends to stray away.
In a commonplace mind, on the other hand, a subject develops much less numerous associates: it dies out then quickly; and, if the man is to keep up thinking of it at all, he must bring his attention back to it by a violent wrench. In him, therefore, the faculty of voluntary attention receives abundant opportunity for cultivation in daily life. It is your despised business man, your common man of affairs, (so looked down on by the literary awarders of fame) whose virtue in this regard is likely to be most developed; for he has to listen to the concerns of so many uninteresting people, and to transact so much drudging detail, that the faculty in question is always kept in training. A genius, on the contrary, is the man in whom you are least likely to find the power of attending to anything insipid or distasteful in itself. He breaks his engagements, leaves his letters unanswered, neglects his family duties incorrigibly, because he is powerless to turn his attention down and back from those more interesting trains of imagery with which his genius constantly occupies his mind.
Voluntary attention is thus an essentially instantaneous affair. You can claim it, for your purposes in the schoolroom, by commanding it in loud, imperious tones; and you can easily get it in this way. But, unless the subject to which you thus recall their attention has inherent power to interest the pupils, you will have got it for only a brief moment; and their minds will soon be wandering again. To keep them where you have called them, you must make the subject too interesting for them to wander again. And for that there is one prescription; but the prescription, like all our prescriptions, is abstract, and, to get practical results from it, you must couple it with mother-wit.
The prescription is that the subject must be made to show new aspects of itself; to prompt new questions; in a word, to change. From an unchanging subject the attention inevitably wanders away. You can test this by the simplest possible case of sensorial attention. Try to attend steadfastly to a dot on the paper or on the wall. You presently find that one or the other of two things has happened: either your field of vision has become blurred, so that you now see nothing distinct at all, or else you have involuntarily ceased to look at the dot in question, and are looking at something else. But, if you ask yourself successive questions about the dot, — how big it is, how far, of what shape, what shade of color, etc.; in other words, if you turn it over, if you think of it in various ways, and along with various kinds of associates, — you can keep your mind on it for a comparatively long time. This is what the genius does, in whose hands a given topic coruscates and grows. And this is what the teacher must do for every topic if he wishes to avoid too frequent appeals to voluntary attention of the coerced sort. In all respects, reliance upon such attention as this is a wasteful method, bringing bad temper and nervous wear and tear as well as imperfect results. The teacher who can get along by keeping spontaneous interest excited must be regarded as the teacher with the greatest skill.
There is, however, in all schoolroom work a large mass of material that must be dull and unexciting, and to which it is impossible in any continuous way to contribute an interest associatively derived. There are, therefore, certain external methods, which every teacher knows, of voluntarily arousing the attention from time to time and keeping it upon the subject. Mr. Fitch has a lecture on the art of securing attention, and he briefly passes these methods in review; the posture must be changed; places can be changed. Questions, after being answered singly, may occasionally be answered in concert. Elliptical questions may be asked, the pupil supplying the missing word. The teacher must pounce upon the most listless child and wake him up. The habit of prompt and ready response must be kept up. Recapitulations, illustrations, examples, novelty of order, and ruptures of routine, — all these are means for keeping the attention alive and contributing a little interest to a dull subject. Above all, the teacher must himself be alive and ready, and must use the contagion of his own example.
But, when all is said and done, the fact remains that some teachers have a naturally inspiring presence, and can make their exercises interesting, while others simply cannot. And psychology and general pedagogy here confess their failure, and hand things over to the deeper springs of human personality to conduct the task."

The Status Competition Model of Cultural Production

Selbstverständlichkeiten:
"Selbstverständlichkeiten [werden] eigentlich erst dann auffällig ..., wenn sie nicht mehr in uneingeschränkter Weise Anerkennung finden. Insofern dies der Fall ist, pflegen Gesellschaftsformen ihre Selbstverständlichkeiten sehr energisch zu schützen. Diese erlangen damit Tabu-Charakter, und Vorstöße gegen sie werden entweder als 'verbrecherisch' oder als 'krankhaft' gebrandmarkt, manchmal als 'Hochverrat'."

'Information-Gathering':

On Chunking:
Some 50000 chunks, about the same magnitude as the recognition vocabulary of college-educated readers, may be required for expert mastery of a given field. The highest achievement in scientific disciplines, however, may require a memory store of a million chunks - probably the equivalent of 70 hours of concentrated effort each week for a decade even for a talented student! Without chunking the whole process would be utterly impossible.
Child prodigies and exceptionally early achievers, to quote the title of an interesting book by Radford (1990), seem able to curtail this prodigious expenditure of mental energy; a Mozart, Newton, or Einstein, by combining outstandingly high IQ, special abilities, motivation and creativity may get by with less, and achieve outstanding success at an abnormally early age. But even for them a long period of information acquisition is needed before creativity can emerge to restructure the chunks now available. Because not only do we have to transmute the material in question into chunks, these chunks are themselves tied together with pretty pink ribbons, and the most difficult task of the genius is to undo these ties, and fit the chunks together in a different pattern."

Prospection Theory:

"People think about the future, not primarily as an attempt to predict what is bound to happen, but as a series of points at which events can go in different directions. The future is less a matter of something to be known than something to be shaped and guided amid multiple alternative possibilities."
