“As for more than twenty years my principal work has been devoted to the ancient literature of India, I cannot but feel a deep and real sympathy for all that concerns the higher interests of the people of that country. Though I have never been in India, I have many friends there, both among the civilians and among the natives, and I believe I am not mistaken in supposing that the publication in England of the ancient sacred writings of the Brahmans, which had never been published in India, and other contributions from different European scholars towards a better knowledge of the ancient literature and religion of India, have not been without some effect on the intellectual and religious movement that is going on among the more thoughtful members of Indian society. I have sometimes regretted that I am not an Englishman, and able to help more actively in the great work of educating and improving the natives. But I do rejoice that this great task of governing and benefiting India should have fallen to one who knows the greatness of that task and all its opportunities and responsibilities, who thinks not only of its political and financial bearings, but has a heart to feel for the moral welfare of those millions of human beings that are, more or less directly, committed to his charge. India has been conquered once, but India must be conquered again, and that second conquest should be a conquest by education. Much has been done for education of late, but if the funds were tripled and quadrupled, that would hardly be enough. The results of the educational work carried on during the last twenty years are palpable everywhere. They are good and bad, as was to be expected. It is easy to find fault with what is called Young Bengal, the product of English ideas grafted on the native mind. But Young Bengal, with all its faults, is full of promise. Its bad features are apparent everywhere, its good qualities are naturally hidden from the eyes of careless observers.... India can never be anglicized, but it can be reinvigorated. By encouraging a study of their own ancient literature, as part of their education, a national feeling of pride and self-respect will be reawakened among those who influence the large masses of the people. A new national literature may spring up, impregnated with Western ideas, yet retaining its native spirit and character. The two things hang together. In order to raise the character of the vernaculars, a study of the ancient classical language is absolutely necessary: for from it these modern dialects have branched off, and from it alone can they draw their vital strength and beauty. A new national literature will bring with it a new national life and new moral vigour. As to religion, that will take care of itself. The missionaries have done far more than they themselves seem to be aware of, nay, much of the work which is theirs they would probably disclaim. The Christianity of our nineteenth century will hardly be the Christianity of India. But the ancient religion of India is doomed — and if Christianity does not step in, whose fault will it be?”

“There is, I venture to think, no ground for the ordinarily accepted statement of the relation of philosophy to theology and religion. It is usually said that while^hilosophy is the creation of an individual mind, theology or religion is, like folk-lore and language, the product of the collective mind of a people or a race. This is to confuse philosophy with philosophies, a conmion and, it must be admitted, a not unnatural confusion. But while a philosophy is the creation of a Plato, an Aristotle, a Spinoza, a Kant, or a Hegel, ^hilosophy itself is, like religion, folk-lore and language, a product of the collective mind of humanity. It is advanced, as these are, by individual additions, interpretations and syntheses, but it is none the less quite istinct from such individual contributions. philosophy is humanity's hold on Totality, and it becomes richer and more helpful as man's intellectual horizon widens, as his intellectual vision grows clearer, and as his insights become more numerous and more sure. Theology is philosophy of a particular type. It is an interpretation of Totality in terms of God and His activities. In the impressive words of Principal Caird, that philosophy which is theology seeks "to bind together objects and events in the links of necessary thought, and to find their last ground and reason in that which comprehends and transcends all— the nature of God Himself." Religion is the apprehension and the adoration of the Grod Whom theology postulates.
If the whole history of philosophy be searched for material with which to instruct the beginner in what philosophy really is and in its relation to theology and religion, the two periods or epochs that stand out above all others as useful for this purpose are Greek thought from Thales to Socrates, and that interpretation of the teachings of Christ by philosophy which gave rise, at the hands of the Church Fathers, to Christian theology. In the first period we see the simple, clear-cut steps by which the mind of Europe was led from explanations that were fairy-tales to a natural, well-analyzed, and increasingly profound interpretation of the observed phenomena of Nature. The process is so orderly and so easily grasped that it is an invaluable introduction to the study of philosophic thinking. In the second period we see philosophy, now enriched by the literally huge contributions of Plato, Aristotle and the Stoics, intertwining itself about the simple Christian tenets and building the great system of creeds and thought which has immortalized the names of Athanasius and Hilary, Basil and Gregory, Jerome and Augustine, and which has given color and form to the intellectual life of Europe for nearly two thousand years. For the student of today both these developments have great practical value, and the astonishing neglect and ignorance of them both are most discreditable.”

“It was not, however, a matter of interest to me only with respect to my divisions, since as a member of the Executive Committee, I was a kind of general executive and so had begun to think from the corporate viewpoint. The important thing was that no one knew how much was being contributed — plus or minus — by each division to the common good of the corporation. And since, therefore, no one knew, or could prove, where the efficiencies and inefficiencies lay, there was no objective basis for the allocation of new investment. This was one of the difficulties with the expansion program of that time. It was natural for the divisions to compete for investment funds, but it was irrational for the general officers of the corporation not to know where to place the money to best advantage. In the absence of objectivity it was not surprising that there was a lack of real agreement among the general officers. Furthermore, some of them had no broad outlook, and used their membership on the Executive Committee mainly to advance the interests of their respective divisions.

“…he thinks that peace is, of all things, the best, and that war is, of all things, the worst. Now, Sir, I happen to be of opinion that there are things for which peace may be advantageously sacrificed, and that there are calamities which a nation may endure which are far worse than war. This has been the opinion of men in all ages whose conduct has been admired by their contemporaries, and has obtained for them the approbation of posterity. The hon. Member, however, reduces everything to the question of pounds, shillings, and pence, and I verily believe that if this country were threatened with an immediate invasion likely to end in its conquest, the hon. Member would sit down, take a piece of paper, and would put on one side of the account the contributions which his Government would require from him for the defence of the liberty and independence of the country, and he would put on the other the probable contributions which the general of the invading army might levy upon Manchester, and if he found that, on balancing the account, it would be cheaper to be conquered than to be laid under contribution for defence, he would give his vote against going to war for the liberties and independence of the country, rather than bear his share in the expenditure which it would entail.”

“In the progress of the work he founded a Collegium Biblieum, or Bible club, consisting of his colleagues Melanchthon, Bugenhagen (Pommer), Cruciger, Justus Jonas, and Aurogallus. They met once a week in his house, several hours before supper. Deacon Georg Rörer (Rorarius), the first clergyman ordained by Luther, and his proof-reader, was also present; occasionally foreign scholars were admitted; and Jewish rabbis were freely consulted. Each member of the company contributed to the work from his special knowledge and preparation. Melanchthon brought with him the Greek Bible, Cruciger the Hebrew and Chaldee, Bugenhagen the Vulgate, others the old commentators; Luther had always with him the Latin and the German versions besides the Hebrew. Sometimes they scarcely mastered three lines of the Book of Job in four days, and hunted two, three, and four weeks for a single word. No record exists of the discussions of this remarkable company, but Mathesius says that "wonderfully beautiful and instructive speeches were made."
At last the whole Bible, including the Apocrypha as "books not equal to the Holy Scriptures, yet useful and good to read," was completed in 1534, and printed with numerous woodcuts.
In the mean time the New Testament had appeared in sixteen or seventeen editions, and in over fifty reprints.
Luther complained of the many errors in these irresponsible editions.
He never ceased to amend his translation. Besides correcting errors, he improved the uncouth and confused orthography, fixed the inflections, purged the vocabulary of obscure and ignoble words, and made the whole more symmetrical and melodious.
He prepared five original editions, or recensions, of his whole Bible, the last in 1545, a year before his death.
The edition of 1546 was prepared by his friend Rörer, and contains a large number of alterations, which he traced to Luther himself. Some of them are real improvements, e. g., Die Liebe höret nimmer auf, for, Die Liebe wird nicht müde (1 Cor. 13:8). The charge that he made the changes in the interest of Philippism (Melanchthonianism), seems to be unfounded.”

“Democracy has failed to dampen the right/left ideological schism, which is historically rooted in the early years of separate state creation. And neither the right nor the left is fully able to provide a convincing alternative vision of how democracy in Korean society can robustly develop and thereby enhance its quality. The rightists/conservatives, who continue to retain their predominant power and influence over the state and civil society, still cling to an old-fashioned, outmoded black-and-white ideology derived from the Cold War period. That ideology can no longer provide a political vision and values and norms pertinent to the post-Cold War era as well as a democratized, highly modernized and globalized social environment. Thereby they have failed to play a leading role in enhancing autonomy of civil society vis-à-vis the state, respecting rule of law, and contributing to bringing social integration and inclusiveness.
On the other hand, the leftists have disappointed many people who expected that the entirely new generations which appeared on the political center stage in the course of democratization could play a decisive role in changing Korean politics. In recent years we have witnessed a growing disillusionment with the radical discourses and ideas as well as with their inability to develop a new type of party politics, deal with the socio-economic problems and provide a certain substantive model for ethical life.”

“There is one feature I notice that is generally missing in cargo cult science. … It's a kind of scientific integrity, a principle of scientific thought that corresponds to a kind of utter honesty — a kind of leaning over backwards. For example, if you're doing an experiment, you should report everything that you think might make it invalid — not only what you think is right about it; other causes that could possibly explain your results; and things you thought of that you've eliminated by some other experiment, and how they worked — to make sure the other fellow can tell they have been eliminated. Details that could throw doubt on your interpretation must be given, if you know them. You must do the best you can — if you know anything at all wrong, or possibly wrong — to explain it. If you make a theory, for example, and advertise it, or put it out, then you must also put down all the facts that disagree with it, as well as those that agree with it. There is also a more subtle problem. When you have put a lot of ideas together to make an elaborate theory, you want to make sure, when explaining what it fits, that those things it fits are not just the things that gave you the idea for the theory; but that the finished theory makes something else come out right, in addition. In summary, the idea is to try to give all of the information to help others to judge the value of your contribution; not just the information that leads to judgement in one particular direction or another.”

“Think deeply about this: what are you going to ask of Christ when you are in his Church? You come stepping in softly, seeking quiet under her vaulted roofs (unless, of course, you come out of mere vanity) in order to forget your problems and preoccupations [-] languidly immersing yourself in the majesty of the sacred chorales and in the aromatic clouds of incense: and then to sleep[-] But this is not the peace of Christ. My peace I give you, my peace I leave you. He said My, which is not the peace of this world. But you want to establish the Church in the peace of the world, and that is why the others, when they come, cannot enter without war cries rising from their overwrought lungs. They rebel, filling the temple with blashemous roars, they eject the terrified faithful, who had been half asleep, they insult or kill the ministers at the altar, knock over the altar itself, smash the stone saints, burn the church [-] so it is that she once again becomes, for them, the church of the Christ that died on the cross. [-] This time, do not leave her rebuilding to others. Do not wish to put up sturdier walls for these will not give her a better defense [-] Nor should you ask the rich to contribute too much money for the reconstruction, lest the poor, should receive the benefice with mistrust. Let it be the poor who rebuild her, for then they will do so according to their fashion and only in this way will they love her.”

“I have been aware from the outset (end of January 1959, the birthdate of the second paper in the citation) that the deep analysis of something which is now called Kalman filtering were of major importance. But even with this immodesty I did not quite anticipate all the reactions to this work. Up to now there have been some 1000 related publications, at least two Citation Classics, etc. There is something to be explained.
To look for an explanation, let me suggest a historical analogy, at the risk of further immodesty. I am thinking of Newton, and specifically his most spectacular achievement, the law of Gravitation. Newton received very ample "recognition" (as it is called today) for this work. it astounded - really floored - all his contemporaries. But I am quite sure, having studied the matter and having added something to it, that nobody then (1700) really understood what Newton's contribution was. Indeed, it seemed an absolute miracle to his contemporaries that someone, an Englishman, actually a human being, in some magic and un-understandable way, could harness mathematics, an impractical and eternal something, and so use mathematics as to discover with it something fundamental about the universe.”

“[Neoinstitutional Economics…] theory has made an indispensable contribution in recent times to advances of understanding in this area. But it seems to me that in the economics of institutions theory is now outstripping empirical research to an excessive extent. No doubt the same could be said of other fields in economics, but there is a particular point about this one. Theoretical modelling may or may not be more difficult in this field than in others, but empirical work is confronted by a special difficulty. Because economic institutions are complex, they do not lend themselves easily to quantitative measurement. Even in the respects in which they do, the data very often are not routinely collected by national statistical offices. As a result, the statistical approach which has become the bread and butter of applied economics is not straightforwardly applicable. Examples of it do exist, the literature on the economics of slavery being perhaps the most fully developed - not surprisingly because slavery is an institution that is sharply defined. But to a large extent the empirical literature has consisted of case-studies which are interesting but not necessarily representative, together with a certain amount on legal court cases, which are almost certainly not representative. Is this the best we can do? There is a challenge here on the empirical side to economists to see what is the best way forward.”

“The pattern of sex differences found in our species mirrors that found in most mammals and in many other animals. As such, considerations of parsimony suggest that the best explanation for the human differences will invoke evolutionary forces common to many species, rather than social forces unique to our own. When we find the standard pattern of differences in other, less culture-bound creatures, we inevitably explain this in evolutionary terms. It seems highly dubious, when we find exactly the same pattern in human beings, to say that, in the case of this one primate species, we must explain it in terms of an entirely different set of causes — learning or cumulative culture — which coincidentally replicates the pattern found throughout the rest of the animal kingdom. Anyone who wishes to adopt this position has a formidable task in front of them. They must explain why, in the hominin lineage uniquely, the standard evolved psychological differences suddenly became maladaptive, and thus why natural selection “wiped the slate clean” of any biological contribution to these differences. They must explain why natural selection eliminated the psychological differences but left the correlated physical differences intact. And they must explain why natural selection would eliminate the psychological differences and leave it all to learning, when learning simply replicated the same sex differences anyway. How could natural selection favor extreme flexibility with respect to sex differences if that flexibility was never exercised and was therefore invisible to selection?”
