小可最近正在练习LSAT阅读，遇到一个暴难的句子。按照杨鹏老师的方法我分析了该句子，但是百思不得其解。理解完全不到位。请高手指点！ The realities with which this technology is occupied are of another order of actuality, lying altogether within the three dimensions that contain the material universe, and running altogether on the logic of material fact. 全文如下（红色部分的就是我要文的句子，全文从LSAT黄皮书中拷贝过来，没有错误）：

As is well known and has often been described, the machine industry of recent times took its rise by a gradual emergence out of handicraft in England in the eighteenth century. Since then the mechanical industry has progressively been getting the upper hand in all the civilized nations, in much the same degree in which these nations have come to be counted as civilized. This mechanical industry now stands dominant at the apex of the industrial system.

The state of the industrial arts, as it runs on the lines of the mechanical industry, is a technology of physics and chemistry. That is to say, it is governed by the same logic as the scientific laboratories. The procedure, the principles, habits of thought, preconceptions, units of measurement and of valuation, are the same in both cases.

The technology of physics and chemistry is not derived from established law and custom, and it goes on its way with as nearly complete a disregard of the spiritual truths of law and custom as the circumstances will permit. The realities with which this technology is occupied are of another order of actuality, lying altogether within the three dimensions that contain the material universe, and running altogether on the logic of material fact. In effect it is the logic of inanimate facts.

The mechanical industry makes use of the same range of facts handled in the same impersonal way and directed to the same manner of objective results. In both cases alike it is of the first importance to eliminate the “personal equation,” to let the work to forward and let the forces at work take effect quite objectively, without hindrance or deflection for any personal end, interest, or gain. It is the technician’s place in industry, as it is the scientist’s place in the laboratory, to serve as an intellectual embodiment of the forces at work, isolate the forces engaged from all extraneous disturbances, and let them take full effect along the lines of designed work. The technician is an active or creative factor in the case only in the sense that he is the keeper of the logic which governs the forces at work.

These forces that so are brought to bear in mechanical industry are of an objective, impersonal, unconventional nature, of course. They are of the nature of opaque fact. Pecuniary gain is not one of these impersonal facts. Andy consideration of pecuniary gain that may be injected into the technician’s working plans will come into the case as an intrusive and alien factor, whose sole effect is to deflect, retard, derange and curtail the work in hand. At the same time considerations of pecuniary gain are the only agency brought into the case by the businessmen, and the only ground on which they exercise a control of production.
