Poincaré analyses how the reality of three dimensional Euclidean (or non-Euclidean) space, has been constructed from our daily experiences as a human being with the objects that are most important for us (rigid bodies), and closely around. This does not mean that this three dimensional space is an ‘invention' of humanity. It exists, but the way we have ordered, and later on formalized it, by means of specific mathematical models, does make part of it. In other words, what we call the three dimensional reality of space partly exists in its own and partly exists by the structures that we have constructed, relying on our specific human experience with it.

The natural way of doing this [seeking scientific knowledge or explanation of fact] is to start from the things which are more knowable and obvious to us and proceed towards those which are clearer and more knowable by nature; for the same things are not 'knowable relatively to us' and 'knowable' without qualification. So in the present inquiry we must follow this method and advance from what is more obscure by nature, but clearer to us, towards what is more clear and more knowable by nature. Now what is to us plain and obvious at first is rather confused masses, the elements and principles of which became known to us by later analysis...
Aristotle
Early entry is appropriate when the following general circumstances hold:
- Image and reputation of the firm are important to the buyer, and the firm can develop an enhanced reputation by being a pioneer.
- Early entry can initiate the learning process in a business in which the learning curve is important, experience is difficult to imitate, and it will not be nullified by successive technological generations.
- Customer loyalty will be great, so that benefits will accrue to the firm that sells to the customer first.
- Absolute cost advantages can be gained by early commitment to supplies of raw materials, distribution channels, and so on.
Michael E. Porter
The national character of the three kingdoms was strongly marked in my army. I found the English regiments always in the best humour when we were well supplied with beef; the Irish when we were in the wine countries, and the Scotch when the dollars for pay came up. This looks like an epigram, but I assure you it was a fact, and quite perceptible; but we managed to reconcile all their tempers, and I will venture to say that in our later campaigns, and especially when we crossed the Pyrenees, there never was an army in the world in better spirits, better order, or better discipline. We had mended in discipline every campaign, until at last (smiling) I hope we were pretty near perfect.
Arthur Wellesley, 1st Duke of Wellington
In another moment I had scrambled up the earthen rampart and stood upon its crest, and the interior of the redoubt was below me. A mighty space it was, with gigantic machines here and there within it, huge mounds of material and strange shelter places. And scattered about it, some in their overturned war-machines, some in the now rigid handling-machines, and a dozen of them stark and silent and laid in a row, were the Martians-dead!-slain by the putrefactive and disease bacteria against which their systems were unprepared; slain as the red weed was being slain; slain, after all man's devices had failed, by the humblest things that God, in his wisdom, has put upon this earth.
H. G. Wells
But the projects with which the architects of Russian proletarian architecture present us are not only based on pure imagination, but their construction would, if they were fitted for realization, entail enormous waste of space and materials. The dwelling complex 'Wolkenbügel' [architecture, designed by Lissitzky, with the help of [ w:Emil Roth - Swiss architect, 1924] (assuming that one could live here without either freezing or melting!), shaped like a 4, stands in a very un-constructive way on three legs in which the elevators are located. The latter take up as much space as would one or more skyscrapers. And these 'architects' are to teach the West what architecture is!
