“But are there not reasons against all this? Is there not such a law or principle as that of self-preservation? Does not every race owe something to itself? Should it not attend to the dictates of common sense? Should not a superior race protect itself from contact with inferior ones? Are not the white people the owners of this continent? Have they not the right to say what kind of people shall be allowed to come here and settle? Is there not such a thing as being more generous than wise? In the effort to promote civilization may we not corrupt and destroy what we have? Is it best to take on board more passengers than the ship will carry? To all this and more I have one among many answers, altogether satisfactory to me, though I cannot promise it will be entirely so to you. I submit that this question of Chinese immigration should be settled upon higher principles than those of a cold and selfish expediency. There are such things in the world as human rights. They rest upon no conventional foundation, but are eternal, universal and indestructible. Among these is the right of locomotion; the right of migration; the right which belongs to no particular race, but belongs alike to all and to all alike. It is the right you assert by staying here, and your fathers asserted by coming here. It is this great right that I assert for the Chinese and the Japanese, and for all other varieties of men equally with yourselves, now and forever. I know of no rights of race superior to the rights of humanity, and when there is a supposed conflict between human and national rights, it is safe to go the side of humanity. I have great respect for the blue-eyed and light-haired races of America. They are a mighty people. In any struggle for the good things of this world, they need have no fear, they have no need to doubt that they will get their full share. But I reject the arrogant and scornful theory by which they would limit migratory rights, or any other essential human rights, to themselves, and which would make them the owners of this great continent to the exclusion of all other races of men. I want a home here not only for the negro, the mulatto and the Latin races, but I want the Asiatic to find a home here in the United States, and feel at home here, both for his sake and for ours.”

“Anarchism does not mean bloodshed; it does not mean robbery, arson, etc. These monstrosities are, on the contrary, the characteristic features of capitalism. Anarchism, or Socialism, means the re-organization of society upon scientific principles and the abolition of causes which produce vice and crime.”

“A very eminent writer has observed, that "the conversion of the Gentile world, whether we consider the difficulties attending it, the opposition made to it, the wonderful work wrought to accomplish it, or the happy effects and consequences of it, may be considered as a more illustrious evidence of God's power, than even our Saviour's miracles of casting out devils, healing the sick, and raising the dead." Indeed, a miracle said to have been wrought without any attending circumstances to justify such an exertion of divine power, could not easily be rendered credible; and our author's argument proves no more. If it were related, that about 1700 years ago, a man was raised from the dead, without its answering any other end than that of restoring him to life, Iconfess that no degree of evidence could induce me tobelieve it; but if the moral government of God appeared in that event, and there were circumstances attending it which could not be accounted for by any human means, the fact becomes credible. When two extraordinary events are thus connected, the proof of one established the truth of the other. Our author has reasoned upon the fact as standing alone, in which case it would not be easy to disprove some of his reasoning; but the fact should be considered in a moral view - as connected with the establishment of a pure religion, and it then becomes credible. In the proof of any circumstance, we must consider every principle which tends to establish it; whereas our author, by considering the case of a man said to have been raised from the dead, simpli in a physical point of view, without any reference to a moral end, endavours to show that it cannot be rendered credible; and, from such principles, we may admit his conclusions without affecting the credibility of Christianity. The general principle on which he establishes his argument, is not the great foundation upon which the evidence of Christianity rests. He says, "Notestimony can be sufficient to establish a miracle, unless it be of such a kind, that the falsehood would be more miraculous than the fact which it endavours to prove." Now this reasoning, at furthest, can only be admitted in those cases where the fact has nothing but testimony to establish it. But the proofs of Christianity do not rest simply upon the testimony of its first promulgators, and that of those who were affterwards the instruments of communicating it; but they rest principally upon the acknowledged and very extraordinary affects which were produced by the preaching of a few unlearned, obscure persons, who taught "Christ crucified;" and it is upon these indisuptable matters of ffact which we reason; and when the effects are totally unaccountable upon any principle which we can collect from the operation of human means, we must either admit miracles, or admit an effect without an adequate cause. Also, when the proof of any position depends upon arguments drawn from various sources, all concutring to establish its turh, to select some one circumstance, and atrempt to show that that alone is not sufficient to render the fact credible, and thence infer that it is not ture, is a conclusion not to be admitted. But it is thus that our author has endavoured to destroy the credibiliry of Christianity, the evidences of which depend upon a great variety of circumstances and facts which are indisputably true, all cooperating to confirm its truth; but an examination of these falls not whithin the plan here proposed. He rests all his arguments upon the extraordinary nature of the fact, considered alone by itself; for a common fact, with the same evidence, would immediately be admitted. I have endavoured to show, that the extraordinary nature, as much as the mosst common events are necessary to fulfill the usual dispensations of Providence, and therefore the Deity was then direted by the same motive as in a more ordinary case, that of affording us such assitance as our moral condition renders necessary. In the establishment of a pur religion, the proof of its divine origin may require some very extraordinary circumstances which may never afterwards be requisite, and accordingly we find that they have not happened. Here is therefore a perfect concistencty in the operation of the Deity, in his moral government, and not a violation of the laws of nature: Secondly, the fact is immediately connected with others which are indisputably true, and which, without the supossition of the truth of that fact, would be, at least, equally miraculous. Thus I conceive the reasoning of our author to be totally inconclusive; and the argumentss which have been employed to prove the fallacy of his conclusions, appear at the same time, fully to justify our belief in, and prove the moral certainty of, our holy religion.”

“All knowledge, not only that of the natural world, can be used for evil as well as good: and in all ages there continue to be people who think that its fruit should be forbidden. Does the future wlfare, therefore, of mankind depend of a refusal of science and a more intensive study of the Sermon on the Mount? There are others who hold the contray opinion, that more and more of science and its applications alone can bring prosperity and happiness to men. Both of these extremes views seem to me entirely wrong - though the second is the more perilous as more likely to be commonly accepted. The so-called conflict between science and religion is usually about words, too often the words of their unbalanced advocates: the reality lies somewhere in between. "Completeness and dignity", to use Tyndall's phrase, are brought to man by three main channels, first by the religiouos sentiment and its embodiment of ethical principles, secondly by the influence of what is beautiful in nature, human personality, or art, and thirdly, by the pursuit of scientific truth and its resolute use in improving human life. Some suppose that religion and beauty are incompatible: others, that the aesthetic has no relation to the scientific sense: both seem to me just as mistaken as those who hold that the scientific and the religious spirit are necessarily opposed. Co-operation is required, not conflict: for science can be used to express and apply the principles of ethics, and those principles themselves can guide the behaviour of scientific men: while the appreciation of what is good and beautiful can provide to both a vision of encouragement. Is there really then any special ethical dilemma which we scientific men, as distinct from other people, have to meet? I think not: unless it be to convince ourselves humbly that we are just like others in having moral issues to face. It is true that integrity of thought is the absolute condition of oour work, and that judgments of value must never be allowed to deflect our judgements of fact. But in this we are not unique. It is true that scientific research has opened up the possibility of unprecedented good, or unlimited harm, for manking: but the use is made of it depends in the end on the moral judgments of the whole community of men. It is totally impossible noew to reverse the process of discovery: it will certainly go on. To help to guide its use aright is not a scientific dilemma, but the honourable and compelling duty of a good citizen.”

“Coming back to Iraq, obviously the situation has been getting worse over time, but I think it is still salvageable. We now have a political process going on, and I think if one looks at the place and what's been happening there, one has to marvel at what has been accomplished. There is an old saying, no news is good news, and the media obviously work on the reverse principle: Good news is no news. Most of the good things that have happened have not been reported, but there has been tremendous progress in many respects. Three elections were held three fair elections in which millions of Iraqis stood in line waiting to vote and knowing they were risking their lives every moment that they did so. And all this wrangling that's going on now is part of the democratic process, the fact that they argue, that they negotiate, that they try to find a compromise. This is part of their democratic education.
So I find all this both annoying and encouraging. I see that more and more people are becoming involved in the political process. And there's one thing in Iraq in particular that I think is encouraging, and that is the role of women. Of all the Arab countries, with the possible exception of Tunisia, Iraq is the one where women have made most progress. I'm not talking about rights, a word that has no meaning in that context. I'm talking about opportunity, access. Women in Iraq had access to education, to higher education, and therefore to the professions, and therefore to the political process to a degree without parallel elsewhere in the Arab world, as I said, with the possible exception of Tunisia. And I think that the participation of women the increasing participation of women is a very encouraging sign for the development of democratic institutions.”

“The first duty of a government is to be true to itself. This does not mean perfection, it means a plan to strive for perfection. It means loyalty to ideals. The ideals of America were set out in the Declaration of Independence and adopted in the Constitution. They did not represent perfection at hand, but perfection found. The fundamental principle was freedom. The fathers knew that this was not yet apprehended. They formed a government firm in the faith that it was ever to press toward this high mark. In selfishness, in greed, in lust for gain, it turned aside. Enslaving others, it became itself enslaved. Bondage in one part consumed freedom in all parts. The government of the fathers, ceasing to be true to itself, was perishing. Five score and ten years ago, that divine providence which infinite repetition has made only the more a miracle, sent into the world a new life destined to save a nation. No star, no sign foretold his coming. About his cradle all was poor and mean, save only the source of all great men, the love of a wonderful woman. When she faded away in his tender years from her deathbed in humble poverty, she endowed her son with greatness. There can be no proper observance of a birthday which forgets the mother. Into his origin, as into his life, men long have looked and wondered. In wisdom great, but in humility greater, in justice strong, but in compassion stronger, he became a leader of men by being a follower of the truth. He overcame evil with good. His presence filled the nation. He broke the might of oppression. He restored a race to its birthright.”

“Nothing is more characteristic of the Hegelian system of knowledge than the fact that upon its highest pinnacle, where it becomes knowledge of knowledge, i. e. knowledge knowing of itself, it is impossible for it to have any other content but simply the history of philosophy, the account of its continuing self-exposition, in which all individual developments, coming full circle, can only be stages along the road to the absolute philosophy reached in Hegel himself. But that which knowledge is explicitly upon this topmost pinnacle as the history of philosophy, the philosophy completed in Hegel, it is implicitly all along the line: the knowledge of history and the history of knowledge, the history of truth, the history of God, as Hegel was able to say: the philosophy of History. History here has entered so thoroughly into reason, philosophy has so basically become the philosophy of history, that reason, the object of philosophy itself, has become history utterly and completely, that reason cannot understand itself other than a sits own history, and that, from the opposite point of view, it is in a position to recognize itself at once in all history in some stage of its life-process, and also in its entirety, so far as the study permits us to divine the whole. It is a matter of the production of self-movement of the thought-content in the consciousness of the thinking subject. It is not a matter of reproduction! The Hegelian way of looking is the looking of a spectator only in so far as it is in fact in principle and exclusively theory, thinking consciousness. Granting this premise, and setting aside Kierkegaard’s objection that with it the spectator might by chance have forgotten himself, that is the practical reality of his existence, then for Hegel it is also in order (only too much in order!) that the human subject, whilst looking in this manner, stands by no means apart as if it were not concerned. It is in this looking that the something seen is produced. And the thing seen actually has its reality in the fact that it is produced as the thing seen in the looking of the human subject. Man cannot participate more energetically (within the frame-work of theoretical possibility), he cannot be more forcefully transferred from the floor of the theatre on to the stage than in his theory.”

“Liberty once again must become more important to us than the desire for security and material comfort. Personal safety and economic prosperity can only come as the consequence of liberty. They cannot be provided by an authoritarian government… The foundation for a police state has been put in place, and it's urgent we mobilize resistance before it's too late… Central planning is intellectually bankrupt – and it has bankrupted our country and undermined our moral principles. Respect for individual liberty and dignity is the only answer to government force, force that serves the politically and economically powerful. Our planners and rulers are not geniuses, but rather demagogues and would-be dictators -- always performing their tasks with a cover of humanitarian rhetoric… The collapse of the Soviet system came swiftly and dramatically, without a bloody conflict… It came as no surprise, however, to the devotees of freedom who have understood for decades that socialism was doomed to fail… And so too will the welfare/warfare state fail… A free society is based on the key principle that the government, the president, the Congress, the courts, and the bureaucrats are incapable of knowing what is best for each and every one of us… A government as a referee is proper, but a government that uses arbitrary force to direct every aspect of society threatens freedom… The time has come for a modern approach to achieving those values that all civilized societies seek. Only in a free society do individuals have the best chance to seek virtue, strive for excellence, improve their economic well-being, and achieve personal happiness… The worthy goals of civilization can only be achieved by freedom loving individuals. When government uses force, liberty is sacrificed and the goals are lost. It is freedom that is the source of all creative energy. If I am to be your president, these are the goals I would seek. I reject the notion that we need a president to run our lives, plan the economy, or police the world… It is much more important to protect individual liberty and privacy than to make government even more secretive and powerful.”

“Element had an existence from the time he [God] had. The pure principles of element are principles which can never be destroyed; they may be organized and re-organized, but not destroyed. They had no beginning, and can have no end.... [T]he mind of man — the immortal spirit. Where did it come from? All learned men and doctors of divinity say that God created it in the beginning; but it is not so: the very idea lessens man in my estimation. I do not believe the doctrine; I know better. Hear it, all ye ends of the world; for God has told me so... We say that God himself is a self-existent being. Who told you so? It is correct enough; but how did it get into your heads? Who told you that man did not exist in like manner upon the same principles? Man does exist upon the same principles. God made a tabernacle and put a spirit into it, and it became a living soul.... The mind or the intelligence which man possesses is [co-eternal] with God himself. I know that my testimony is true... Is it logical to say that the intelligence of spirits is immortal, and yet that it had a beginning? The intelligence of spirits had no beginning, neither will it have an end. That is good logic. That which has a beginning may have an end. There never was a time when there were not spirits; for they are [co-eternal] with our Father in heaven.... I take my ring from my finger and liken it unto the mind of man—the immortal part, because it has no beginning. Suppose you cut it in two; then it has a beginning and an end; but join it again, and it continues one eternal round. So with the spirit of man. As the Lord liveth, if it had a beginning, it will have an end. All the fools and learned and wise men from the beginning of creation, who say that the spirit of man had a beginning, prove that it must have an end; and if that doctrine is true, then the doctrine of annihilation would be true. But if I am right, I might with boldness proclaim from the house-tops that God never had the power to create the spirit of man at all. God himself could not create himself.”

“The principle of enslaving human beings because they are inferior, is this. If a man is a cripple, trip him up. If he is old and weak, and bowed with the weight of years, strike him, for he cannot strike back. If idiotic, take advantage of him, and if a child, deceive him. This, sir, this is the doctrine of Democrats and the doctrine of devils as well, and there is no place in the universe outside the five points of hell and |the Democratic Party where the practice and prevalence of such doctrines would not be a disgrace.”

“What mathematics, therefore are expected to do for the advanced student at the university, Arithmetic, if taught demonstratively, is capable of doing for the children even of the humblest school. It furnishes training in reasoning, and particularly in deductive reasoning. It is a discipline in closeness and continuity of thought. It reveals the nature of fallacies, and refuses to avail itself of unverified assumptions. It is the one department of school-study in which the sceptical and inquisitive spirit has the most legitimate scope; in which authority goes for nothing. In other departments of instruction you have a right to ask for the scholar’s confidence, and to expect many things to be received on your testimony with the understanding that they will be explained and verified afterwards. But here you are justified in saying to your pupil “Believe nothing which you cannot understand. Take nothing for granted.” In short, the proper office of arithmetic is to serve as elementary 268 training in logic. All through your work as teachers you will bear in mind the fundamental difference between knowing and thinking; and will feel how much more important relatively to the health of the intellectual life the habit of thinking is than the power of knowing, or even facility of achieving visible results. But here this principle has special significance. It is by Arithmetic more than by any other subject in the school course that the art of thinking—consecutively, closely, logically—can be effectually taught.”
