“Human beings hold two types of theories of action. There is the one that they espouse, which is usually expressed in the form of stated beliefs and values. Then there is the theory that they actually use; this can only be inferred from observing their actions, that is, their actual behavior.”

“I love Turkey. I first traveled there in my early twenties, when I was obsessed by the 1915 Dardanelles campaign. I immediately liked the people — brave, stoical, generous, hospitable and patriotic, if a little inclined to conspiracy theories. I saw Turkey as a model for the region, a successful, Western-oriented Muslim democracy.”

“Whenever I had an opportunity to address the people in different parts of our province, I told them clearly that indeed, I was of the opinion that India should not be divided because today in India we have witnessed the result. Thousands and thousands of young and old, children, men, and women were massacred and ruined. But now that the division is an accomplished fact, the dispute is over. " I delivered many speeches against the division of India, but the question is: has anybody listened to me? You may hold any opinion about me, but I am not a man of destruction but of construction. If you study my life, you will find that I devoted it to the welfare of our country. We have proclaimed that if the Government of Pakistan would work for our people and our country the Khudai Khidmatgars would be with them. I repeat that I am not for the destruction of Pakistan. In destruction lies no good. "Neither Hindus nor Muslims, nor the Frontier, not Punjab, Bengal or Sindh stands to gain from it. There is advantage only in construction. I want to tell you categorically I will not support anybody in destruction. If any constructive programme is before you, if you want to do something constructive for our people, not in theory, but in practice, I declare before this House that I and my people are at your service…”

“The applications of science are inevitable and unquotable for all countries and people today. But something more than its application is necessary. It is the scientific approach, the adventurous, and critical temper of science, the search for truth and new knowledge, the refusal to accept anything without testing and trial, the capacity to change previous conclusions in the face of new evidence, the reliance on observed fact and not on pre-conceived theory, the hard discipline of the mind – all this is necessary, not merely for the too many scientists today, who swear by science, forget all about it outside their particular sphere. The scientific approach and temper or should be a way of life, a process of thinking, a method of acting, associating, with our fellow men. That is a large order and undoubtedly very few if any at all can function in this way with even partial success. But his [Nehru] criticism applies in equal or even greater measure to all the injunctions which philosophy and religion have laid upon us. The scientific temper points out the way along which man should travel. It is the temper of a free man. We live in a scientific age, so we are told but there is little evidence of this temper in the people anywhere or even in their leaders.”

K. R. Narayanan (1920–2005) 9th Vice President and the 10th President of India

“The initial thesis of my enterprise - on the basis of which this entanglement of periodizations is organized by extracting the sense of each - is this following: the science of being qua being has existed since the Greeks - such is the sense and status of mathematics. However, it is only today that we have the means to know this. It follows from this thesis that philosophy is not centered on on ontology - which exists as a separate and exact discipline- rather it circulates between this ontology (this, mathematics), the modern theories of he subject and its own history. The contemporary complex of the conditions of philosophy includes everything referred to in my first three statements: the history of 'Western'thought, post-Cantorian mathematics, psychoanalysis, contemporary art and politics. Philosophy does not coincide with any of these conditions; nor does it map out the totality to which they belong. What philosophy must do is purpose a conceptual framework in which the contemporary compossibilty of these conditions can be grasped. Philosophy can only do this - and this is what frees it from any foundational ambition, in which it would lose itself- by designating amongst its own conditions, as a singular discursive situation, ontology itself in the form of pure mathematics. This is precisely what delivers philosophy and ordains it to the care of truths.”

“All who are weary and heavy laden; all who suffer under injustice; all who suffer from the outrages of the existing bourgeois society; all who have in them the feeling of the worth of humanity, look to us, turn hopefully to us, as the only party that can bring rescue and deliverance. And if we, the opponents of this unjust world of violence, suddenly reach out the hand of brotherhood to it, conclude alliances with its representatives, invite our comrades to go hand in hand with the enemy whose misdeeds have driven the masses into our camp, what confusion must result in their minds! … It must be that for the hundreds and thousands, for the millions that have sought salvation under our banner, it was all a colossal mistake for them to come to us. If we are not different from the others, then we are not the right ones – the Savior is yet to come; and the Social Democracy was a false Messiah, no better than the other false ones! Just in this fact lies our strength, that we are not like the others, and that we are not only not like the others, and that we are not simply different from the others, but that we are their deadly enemy, who have sworn to storm and demolish the Bastile of Capitalism, whose defenders all those others are. Therefore we are only strong when we are alone. This is not to say that we are to individualise or to isolate ourselves. We have never lacked for company, and we never shall so long as the fight lasts. On the essentially true but literally false phrase about a “single reactionary mass,” the Social Democracy has never believed since it passed from the realm of theory to that of practice. We know that the individual members and divisions of the “single reactionary mass” are in conflict with each other, and we have always used these conflicts for our purposes. We have used opponents against opponents, but have never allowed them to use us.”

“The chroniclers of the early Turkish rulers of India take pride in affirming that Qutbuddin Aibak was a killer of lakhs of infidels. Leave aside enthusiastic killers like Alauddin Khalji and Muhammad bin Tughlaq, even the "kind-hearted" Firoz Tughlaq killed more than a lakh Bengalis when he invaded their country. Timur Lang or Tamerlane says he killed a hundred thousand infidel prisoners of war in Delhi. He built victory pillars from severed heads at many places. These were acts of sultans. The nobles were not lagging behind. One Shaikh Daud Kambu is said to have killed 20,000 with his dagger. The Bahmani sultans of Gulbarga and Bidar considered it meritorious to kill a hundred thousand Hindu men, women and children every year….. The rite of Jauhar killed the women, the tradition of not deserting the field of battle made Rajputs and others die fighting in large numbers. When Malwa was attacked (1305), its Raja is said to have possessed 40,000 horse and 100,000 foot.43 After the battle, "so far as human eye could see, the ground was muddy with blood"…. Under Muhammad Tughlaq, wars and rebellions knew no end. His expeditions to Bengal, Sindh and the Deccan, as well as ruthless suppression of twenty-two rebellions, meant only depopulation in the thirteenth and first half of the fourteenth century. For one thing, in spite of constant efforts no addition of territory could be made by Turkish rulers from 1210 to 1296; for another the Turkish rulers were more ruthless in war and less merciful in peace. Hence the extirpating massacres of Balban, and the repeated attacks by others on regions already devastated but not completely subdued….. Mulla Daud of Bidar vividly describes the war between Muhammad Shah Bahmani and the Vijayanagar King in 1366 in which "Farishtah computes the victims on the Hindu side alone as numbering no less than half a million." Muhammad also devastated the Karnatak region with vengeance….. Under Akbar and Jahangir "five or six hundred thousand human beings were killed," says emperor Jahangir. The figures given by these killers and their chroniclers may be a few thousand less or a few thousand more, but what bred this ambition of cutting down human beings without compunction was the Muslim theory, practice and spirit of Jihad, as spelled out in Muslim scriptures and rules of administration.”

“The Prime Minister constantly asserts that the nuclear weapon has kept the peace in Europe for the last 40 years… Let us go back to the middle 1950s or to the end of the 1940s, and let us suppose that nuclear power had never been invented… I assert that in those circumstances there would still not have been a Russian invasion of western Europe. What has prevented that from happening was not the nuclear hypothesis… but the fact that the Soviet Union knew the consequences of such a move, consequences which would have followed whether or not there were 300,000 American troops stationed in Europe. The Soviet Union knew that such an action on its part would have led to a third world war—a long war, bitterly fought, a war which in the end the Soviet Union would have been likely to lose on the same basis and in the same way as the corresponding war was lost by Napoleon, by the Emperor Wilhelm and by Adolf Hitler…
For of course a logically irresistible conclusion followed from the creed that our safety depended upon the nuclear capability of the United States and its willingness to commit that capability in certain events. If that was so—and we assured ourselves for 40 years that it was—the guiding principle of the foreign policy of the United Kingdom had to be that, in no circumstances, must it depart from the basic insights of the United States and that any demand placed in the name of defence upon the United Kingdom by the United States was a demand that could not be resisted. Such was the rigorous logic of the nuclear deterrent…
It was in obedience to it… that the Prime Minister said, in the context of the use of American bases in Britain to launch an aggressive attack on Libya, that it was "inconceivable" that we could have refused a demand placed upon this country by the United States. The Prime Minister supplied the reason why: she said it was because we depend for our liberty and freedom upon the United States. Once let the nuclear hypothesis be questioned or destroyed, once allow it to break down, and from that moment the American imperative in this country's policies disappears with it.
A few days ago I was reminded, when reading a new biography of Richard Cobden, that he once addressed a terrible sentence of four words to this House of Commons. He said to hon. Members: "You have been Englishmen." The strength of those words lies in the perfect tense, with the implication that they were so no longer but had within themselves the power to be so again. I believe that we now have the opportunity, with the dissolution of the nightmare of the nuclear theory, for this country once again to have a defence policy that accords with the needs of this country as an island nation, and to have a foreign policy which rests upon a true, undistorted view of the outside world. Above all, we have the opportunity to have a foreign policy that is not dictated from outside to this country, but willed by its people. That day is coming. It may be delayed, but it will come.”

“Discover the truth through practice, and again through practice verify and develop the truth. Start from perceptual knowledge and actively develop it into rational knowledge; then start from rational knowledge and actively guide revolutionary practice to change both the subjective and the objective world. Practice, knowledge, again practice, and again knowledge. This form repeats itself in endless cycles, and with each cycle the content of practice and knowledge rises to a higher level. Such is the whole of the dialectical-materialist theory of knowledge, and such is the dialectical-materialist theory of the unity of knowing and doing.”

“I don't know. There are many theories about it. The most interesting theory that I've heard so far, which is nothing more than a theory, I can't—think it can't be proved, is that he was warned ahead of time by the Saudis. Now, who knows what the real situation is, but the trouble is that by suppressing that kind of information, you lead to those kinds of theories, whether they have any truth to them or not, and then eventually they get repeated as fact. So I think the president is taking a great risk by suppressing the clear, the key information that needs to go to the Kean commission.”

“The advance of science is not comparable to the changes of a city, where old edifices are pitilessly torn down to give place to new, but to the continuous evolution of zoologic types which develop ceaselessly and end by becoming unrecognizable to the common sight, but where an expert eye finds always traces of the prior work of the centuries past. One must not think then that the old-fashioned theories have been sterile or vain.”

Il ne faut pas comparer la marche de la science aux transformations d’une ville, où les édifices vieillis sont impitoyablement jetés à bas pour faire place aux constructions nouvelles, mais à l’évolution continue des types zoologiques qui se développent sans cesse et finissent par devenir méconnaissables aux regards vulgaires, mais où un œil exercé retrouve toujours les traces du travail antérieur des siècles passés. Il ne faut donc pas croire que les théories démodées ont été stériles et vaines.
