In Darwin's time no serious attempt had been made to examine the manifestations of variability. A vast assemblage of miscellaneous facts could formerly be adduced as seemingly comparable illustrations of the phenomenon "Variation." Time has shown this mass of evidence to be capable of analysis. When first promulgated it produced the impression that variability was a phenomenon generally distributed amongst living things in such a way that the specific divisions must be arbitrary. When this variability is sorted out, and is seen to be in part a result of hybridisation, in part a consequence of the persistence of hybrids by parthenogenetic reproduction, a polymorphism due to the continued presence of individuals representing various combinations of Mendelian allelomorphs, partly also the transient effect of alteration in external circumstances, we see how cautious we must be in drawing inferences as to the indefiniteness of specific limits from a bare knowledge that intermediates exist.

The social sciences building at the University of Chicago indeed still bears since it was built 40 years ago on its outside an inscription taken from the famous physicist Lord Kelvin: "When you cannot measure, your knowledge is meager and unsatisfactory." I will admit that that may be true, but it is certainly not scientific to insist on measurement where you don't know what your measurements mean. There are cases where measurements are not relevant. What has done much damage to microeconomics is striving for a pseudo-exactness by imitating methods of the physical sciences which have to deal with what are fundamentally much more simple phenomena. And the assumption that it is possible to ascertain all the relevant particular facts still completely dominates the alternative methods of dealing with our constitutional ignorance, which economists have tried to overcome. This of course, is what has come to be called macroeconomics as distinct from microeconomics.
Friedrich Hayek
The economic policy issues that we debate today-trade policy, inflation, the proper role of government, the eradication of poverty, and the means of raising the rate of economic growth-have been discussed by economists for more than two centuries. Many of today's economic policies-both the good ones and the bad-are the result of the ideas of those past economists. And many of today's debates about economic policy can be understood only by those who have at least some familiarity with the ideas of earlier economists.
The giants of economic science during the past two hundred years have been men concerned with the critical policy issues of their time. They studied the working of the economy in order to advocate better economic policies. But despite their concern with policy, they were not polemicists or politicians but men who sought to persuade their contemporaries in government and in the broader public by analysis and evidence that would meet the standards of professional debate.

Indeed, over the years I have had many a good laugh at the pompous moralism and blatant dishonesty of India's so-called secularists. Their specialty is to justify double standards, e. g. why mentioning murdered Kashmiri Pandits is "communal hate-mongering” while the endless litany about murdered Gujarati Muslims is "secular consciousness-raising”. Sometimes they merely stonewall inconvenient information, such as when they tried to deny and suppress the historical data about the forcible replacement of a Rama temple in Ayodhya by a mosque: given the strength of the evidence, all they could do was to drown out any serious debate with screams and swearwords. But often they do bring out their specific talents at sophistry, such as when they argue that a Common Civil Code, a defining element of all secular states, is a Hindu communalist notion, while the preservation of the divinely-revealed Shari'a for the Muslims is secular. That's when they are at their best.

Our military force at this moment is as efficient in discipline as it is in numbers; and this not only in the regular army, but in the militia, volunteers, and other descriptions of force. We have six hundred thousand men in arms, besides a navy of two hundred thousand. The masculine energies of the nation were never more conspicuous, and the country never at any period of its history stood in so proud and glorious a position, as at present. After a conflict for fifteen years, against an enemy whose power had been progressively increasing, we are still able to maintain the war with augmenting force and a population, by the pressure of external circumstances, consolidated into an impregnable military mass. Our physical strength has risen when it has been called for; and if we do not present the opposition of numerous fortresses to an invader as the continent does, we present the more insuperable barrier of a high-spirited, patriotic, and enthusiastic people.

It is difficult to make a general judgement about genetic modification (GM), whether vegetable or animal, medical or agricultural, since these vary greatly among themselves and call for specific considerations. The risks involved are not always due to the techniques used, but rather to their improper or excessive application. Genetic mutations, in fact, have often been, and continue to be, caused by nature itself. Nor are mutations caused by human intervention a modern phenomenon. The domestication of animals, the crossbreeding of species and other older and universally accepted practices can be mentioned as examples. We need but recall that scientific developments in GM cereals began with the observation of natural bacteria which spontaneously modified plant genomes. In nature, however, this process is slow and cannot be compared to the fast pace induced by contemporary technological advances, even when the latter build upon several centuries of scientific progress.
