Computational reducibility may well be the exception rather than the rule: Most physical questions may be answerable only through irreducible amounts of computation. Those that concern idealized limits of infinite time, volume, or numerical precision can require arbitrarily long computations, and so be formally undecidable.

In some situations however, when you are deeply with your problem, you feel at home anywhere just thinking about your problem. Some of my best work was done in hotels, on the train, and there's no rule. More important when you think is what goes on inside rather outside. [...] The best thoughts can be nearly everywhere.
Cédric Villani
One of the things that kept most comics from being monthly was that very few artists could produce 24 pages per month. Jack Kirby was very much the exception to the rule, but his towering presence at Marvel started to dictate the whole shape of the industry-and that's where problems set in!
John Byrne
This mutual dependencies no longer the dialectical relationship between master and servant, which has been broken in the struggle for mutual recognition, but rather a vicious circle which encloses both the master and the servant. Do the technicians rule, or is their rule that of the others, who rely on the technicians as their planners and executors?
Herbert Marcuse
The world, and whatever that be which we call the heavens, by the vault of which all things are enclosed, we must conceive to be a deity, to be eternal, without bounds, neither created nor subject at any time to destruction. To inquire what is beyond it is no concern of man; nor can the human mind form any conjecture concerning it.
Pliny the Elder
