The fact that the regions of nature actually covered by known laws are few and fragmentary is concealed by the natural tendency to crowd our experience into those particular regions and to leave the others to themselves. We seek out those parts that are known and familiar and avoid those that are unknown and unfamiliar. This is simply what is called 'Applied Science.'
One of the chief inhibitions to human progress arises because of the extreme slowness with which the advances in knowledge become translated into action for the benefit of society as a whole. There is no step more important for the removal of that inhibition than that of providing for intimate contact between the leaders in the fields of pure and applied science.
Now, if doctors were aware that medicine was not a science and that they were pulling what is undoubtedly the largest and most successful confidence trick ever tried the damage would be fairly minimal. But the problem is compounded by the fact that the vast majority of doctors believe the lie that they are taught; they believe that they are scientists, practising an applied science.
There is no such thing as a special category of science called applied science; there is science and its applications, which are related to one another as the fruit is related to the tree that has borne it.
Government is itself an art, one of the subtlest of the arts. It is neither business, nor technology, nor applied science. It is the art of making men live together in peace and with reasonable happiness.
Rather than ennobling the public mind and cementing the social fabric, applied science speedily became the chief weapon of a gross individualism, which was anathema to the frugal and righteous (John Quincy) Adams, the source of enormous fortunes divorced from duty, the instrument of unscrupulous ambition and rapacious materialism. Presently, it came to scar the very of the country which Adams loved, a disfiguring process uninterrupted since his day.
The aims of pure basic science, unlike those of applied science, are neither fast-flowing nor pragmatic. The quick harvest of applied science is the useable process, the medicine, the machine. The shy fruit of pure science is understanding.
The field of scientific abstraction encompasses independent kingdoms of ideas and of experiments and within these, rulers whose fame outlasts the centuries. But they are not the only kings in science. He also is a king who guides the spirit of his contemporaries by knowledge and creative work, by teaching and research in the field of applied science, and who conquers for science provinces which have only been raided by craftsmen.
