Unsere moderne Lebensweise überfordert sehr oft unsere mentalen Kapazitäten. Es ist erstaunlich, mit welcher Klarsicht manche Autoren die Gefahren mentaler ‚Fehlerhnährung‘ (einhergehend mit mentaler Verwahrlosug, mentaler Trägheit und Süchtigkeit) gesehen haben. Zu ihnen gehören Lewis Carroll und Alan Watts. Seit der ‚medialen Überreizung‘ durch permanent mobile Telekommunikation ist alles noch gefährlicher geworden. – Nachfolgend eine paar Auszüge (zur Selbst-Testung und Selbstreflexion empfohlen!):
Lewis Carroll’s entertaining “test” for healthy mental digestion:
„To ascertain the healthiness of the mental appetite of a human animal, place in its hands a short, well-written, but not exciting treatise on some popular subject — a mental bun, in fact. If it is read with eager interest and perfect attention, and if the reader can answer questions on the subject afterwards, the mind is in first-rate working order. If it be politely laid down again, or perhaps lounged over for a few minutes, and then, ‘I can’t read this stupid book! Would you hand me the second volume of “The Mysterious Murder”?’ you may be equally sure that there is something wrong in the mental digestion.“
What about the consequences of serious neglect of the mind?
„……Life depends on the body being fed, whereas we can continue to exist as animals (scarcely as men) though the mind be utterly starved and neglected. Therefore Nature provides that, in case of serious neglect of the body, such terrible consequences of discomfort and pain shall ensue, as will soon bring us back to a sense of our duty: and some of the functions necessary to life she does for us altogether, leaving us no choice in the matter. It would fare but ill with many of us if we were left to superintend our own digestion and circulation. . . . The consequences of neglecting the body can be clearly seen and felt; and it might be well for some if the mind were equally visible and tangible—if we could take it, say, to the doctor, and have its pulse felt…..
………we should set ourselves to provide for our mind its proper kind of food. We very soon learn what will, and what will not, agree with the body, and find little difficulty in refusing a piece of the tempting pudding or pie which is associated in our memory with that terrible attack of indigestion, and whose very name irresistibly recalls rhubarb and magnesia; but it takes a great many lessons to convince us how indigestible some of our favorite lines of reading are, and again and again we make a meal of the unwholesome novel, sure to be followed by its usual train of low spirits, unwillingness to work, weariness of existence — in fact, by mental nightmare.
…..Then, again, though the food be wholesome and in proper amount, we know that we must not consume too many kinds at once. Take the thirsty a quart of beer, or a quart of cider, or even a quart of cold tea, and he will probably thank you (though not so heartily in the last case!). But what think you his feelings would be if you offered him a tray containing a little mug of beer, a little mug of cider, another of cold tea, one of hot tea, one of coffee, one of cocoa, and corresponding vessels of milk, water, brandy-and-water, and butter-milk? The sum total might be a quart, but would it be the same thing to the haymaker?
Having settled the proper kind, amount, and variety of our mental food, it remains that we should be careful to allow proper intervals between meal and meal, and not swallow the food hastily without mastication, so that it may be thoroughly digested; both which rules, for the body, are also applicable at once to the mind.
First, as to the intervals: these are as really necessary as they are for the body, with this difference only, that while the body requires three or four hours’ rest before it is ready for another meal, the mind will in many cases do with three or four minutes.
…..I believe that the interval required is much shorter than is generally supposed, and from personal experience, I would recommend anyone, who has to devote several hours together to one subject of thought, to try the effect of such a break, say once an hour, leaving off for five minutes only each time, but taking care to throw the mind absolutely ‘out of gear’ for those five minutes, and to turn it entirely to other subjects. It is astonishing what an amount of impetus and elasticity the mind recovers during those short periods of rest.
And then, as to the mastication of the food, the mental process answering to this is simply thinking over what we read. This is a very much greater exertion of mind than the mere passive taking in the contents of our Author. So much greater an exertion is it, that, as Coleridge says, the mind often ‘angrily refuses’ to put itself to such trouble—so much greater, that we are far too apt to neglect it altogether, and go on pouring in fresh food on the top of the undigested masses already lying there, till the unfortunate mind is fairly swamped under the flood. But the greater the exertion the more valuable, we may be sure, is the effect. One hour of steady thinking over a subject (a solitary walk is as good an opportunity for the process as any other) is worth two or three of reading only. And just consider another effect of this thorough digestion of the books we read; I mean the arranging and ‘ticketing,’ so to speak, of the subjects in our minds, so that we can readily refer to them when we want them.“
Zum Abschluss noch Alan Watts über die Sucht erzeugende Struktur moderner Lebensweise (1951 geschrieben!):
„The “brainy” economy designed to produce happiness is a fantastic vicious circle which must either manufacture more and more pleasures or collapse –providing a constant titillation of the ears, eyes, and nerve ends with incessant streams of almost inescapable noise and visual distractions. The perfect “subject” for the aims of this economy is the person who continuously itches his ears with the radio, preferably using the portable kind which can go with him at all hours and in all places. His eyes flit without rest from television screen, to newspaper, to magazine, keeping him in a sort of orgasm-without-release through a series of teasing glimpses of shiny automobiles, shiny female bodies, and other sensuous surfaces, interspersed with such restorers of sensitivity — shock treatments — as “human interest” shots of criminals, mangled bodies, wrecked airplanes, prize fights, and burning buildings. The literature or discourse that goes along with this is similarly manufactured to tease without satisfaction, to replace every partial gratification with a new desire.“
