By 1700 all of the familiar members of the [number] system... were known. However, opposition to the newer types of numbers was expressed throughout the century. Typical are the objections of... Baron Francis Masères... in 1759 his Dissertation on the Use of the Negative Sign in Algebra... shows how to avoid negative numbers... and especially negative roots, by carefully segregating the types of quadratic equations so that those with negative roots are considered separately; and... the negative roots are to be rejected.

The Orient that appears in Orientalism, then, is a system of representations framed by a whole set of forces that brought the Orient into Western learning, Western consciousness, and later, Western empire. ... The Orient is the stage on which the whole East is confined. On this stage will appear the figures whose role it is to represent the larger whole from which they emanate. The Orient then seems to be, not an unlimited extension beyond the familiar European world, but rather a closed field, a theatrical stage affixed to Europe.
Edward Said
All things... appear to be made up and produced by the coming together of these elements, so that they have been distributed by nature among an infinite number of kinds of things. Hence I believed it right to treat of the diversity and practical peculiarities of these things as well as of the qualities which they exhibit in buildings, so that persons who are intending to build may understand them and so make no mistake, but may gather materials which are suitable to use in their buildings.

General Systems Theory is a name which has come into use to describe a level of theoretical model-building which lies somewhere between the highly generalized constructions of pure mathematics and the specific theories of the specialized disciplines. Mathematics attempts to organize highly general relationships into a coherent system, a system however which does not have any necessary connections with the "real" world around us. It studies all thinkable relationships abstracted from any concrete situation or body of empirical knowledge.

In life we only try to produce, to win, and enjoy the more we can; in science, to discoverand invent the more we can; in religion, to dominate (or rule over) on the greatest number of people we can; whereas the forming of the character, the further development (or in-dept analysis, "appronfondissement", Fr.) of the faculties of the intelligence ("les facultés de l'intelligence", Fr.), the refinement of the consciousness and of the heart, are considered incidental (or subordinate) things.

We don't believe it's possible to protect digital content ... What's new is this amazingly efficient distribution system for stolen property called the Internet - and no one's gonna shut down the Internet. And it only takes one stolen copy to be on the Internet. And the way we expressed it to them is: Pick one lock - open every door. It only takes one person to pick a lock. Worst case: Somebody just takes the analog outputs of their CD player and rerecords it - puts it on the Internet. You'll never stop that. So what you have to do is compete with it.
