I've had letters from Chinese scientists at the peak of the SARS epidemic who said the problem is a hybridization between the viruses planted into GMO feed, which is then fed to animals, then the virus jumped from the animals to humans. We're going to see more and more of these kinds of risks. I think the whole issue of the H1N1 virus was the fact that it had genes for three influenza types--human, chicken, pig. All of these crossings are becoming possible because of the crossing of genes across species barriers.

The foxes have holes, and the birds of the air have nests; but the Son of man hath not where to lay his head.

In the present state of society it appears necessary to go back to first principles in search of the most simple truths, and to dispute with some prevailing prejudice every inch of ground. To clear my way, I must be allowed to ask some plain questions, and the answers will probably appear as unequivocal as the axioms on which reasoning is built; though, when entangled with various motives of action, they are formally contradicted either by the words or conduct of men.

Jesus said that God was not the God of the dead, but of the living. And the other life is not, in fact, thinkable to us except under the same forms as those of this earthly and transitory life.

We scarce ever had a prince, who by fraud, or violence, had not made some infringement on the constitution. We scarce ever had a parliament which knew, when it attempted to set limits to the royal authority, how to set limits to its own. Evils we have had continually calling for reformation, and reformations more grievous than any evils. Our boasted liberty sometimes trodden down, sometimes giddily set up, and ever precariously fluctuating and unsettled; it has only been kept alive by the blasts of continual feuds, wars, and conspiracies.

Man's being is made of such strange stuff as to be partly akin to nature and partly not, at once natural and extranatural, a kind of ontological centaur, half immersed in nature, half transcending it.

The possession and the exercise of political, and among others of electoral, rights, is one of the chief instruments both of moral and of intellectual training for the popular mind; and all governments must be regarded as extremely imperfect, until every one who is required to obey the laws, has a voice, or the prospect of a voice, in their enactment and administration.

I asked my guide how it was possible the judicious part of them could suffer such incoherent prating? "We are obliged," said he, "to suffer it, because no one knows, when a brother rises up to hold forth, whether he will be moved by the spirit or by folly. In this uncertainty, we listen patiently to every one. We even allow our women to speak in public; two or three of them are often inspired at the same time, and then a most charming noise is heard in the Lord's house." "You have no priests, then?" said I. "No, no, friend," replied the Quaker; "heaven make us thankful!" Then opening one of the books of their sect, he read the following words in an emphatic tone: "'God forbid we should presume to ordain any one to receive the Holy Spirit on the Lord's day, in exclusion to the rest of the faithful!'

I believe the Indian then to be in body and mind equal to the white man.

Proceeding from ourselves, from our own human consciousness, the only consciousness which we feel from within and in which feeling is identical with being, we attribute some sort of consciousness, more or less dim, to all living things, and even to the stones themselves, for they also live. And the evolution of organic beings is simply the struggle to realize fullness of consciousness through suffering, a continual aspiration to be others without ceasing to be themselves, to break and yet to preserve their proper limits.

Louisiana, as ceded by France to the United States, is made a part of the United States; its white inhabitants shall be citizens, and stand, as to their rights and obligations, on the same footing with other citizens of the United States, in analogous situations.

There is nothing so eternally adhesive as the memory of power.

The great secret of success is to go through life as a man who never gets used up. That is possible for him who never argues and strives with men and facts, but in all experience retires upon himself, and looks for the ultimate cause of things in himself.

The Scientific discourse extracts truths from the errors which surround and oppose it on all sides and in every form; and, by demolition of these opposing views as error, and as impossible to true thought, shows the truth as that which alone remains after their withdrawal, and therefore as the only possible truth:--and in this separation of opposites, and elucidation of the truth from the confused chaos in which truth and error lie mingled together, consists the peculiar and characteristic nature of the Scientific discourse. This method creates and produces truth, before our eyes, out of a world full of error.

Often it is only after immense intellectual effort, which may have continued over centuries, that humanity at last succeeds in achieving knowledge of a concept in its pure form, by stripping off the irrelevant accretions which veil it from the eye of the mind.

Consider the Koran... this wretched book was sufficient to start a world-religion, to satisfy the metaphysical need of countless millions for twelve hundred years, to become the basis of their morality and of a remarkable contempt for death, and also to inspire them to bloody wars and the most extensive conquests. In this book we find the saddest and poorest form of theism. Much may be lost in translation, but I have not been able to discover in it one single idea of value.

I see your vile implication. My only explanation for it is that you are criminally insane.

Genius, in truth, means little more than the faculty of perceiving in an unhabitual way.

Character is destiny.

The Methods of Observation of Quantity in general, are 'Numeration', which is precise by the nature of Number; the 'Measurement of Space' and 'of Time', which are easily made precise; the 'Conversion of Space and Time', by which each aids the measurement of the other. The Idea of Space becomes more clear by studying 'Geometry'; the Idea of Force, by studying 'Mechanics'; the Ideas of Likeness, of Kind, of subordination of Classes, by studying 'Natural History'.

The highest perfection of human life consists in the mind of man being detached from care, for the sake of God.

We are told that a utilitarian will be apt to make his own particular case an exception to moral rules, and, when under temptation, will see a utility in the breach of a rule, greater than he will see in its observance. But is utility the only creed which is able to furnish us with excuses for evil doing, and means of cheating our own conscience? They are afforded in abundance by all doctrines which recognise as a fact in morals the existence of conflicting considerations; which all doctrines do, that have been believed by sane persons. It is not the fault of any creed, but of the complicated nature of human affairs, that rules of conduct cannot be so framed as to require no exceptions, and that hardly any kind of action can safely be laid down as either always obligatory or always condemnable.

What is important is that sex was not only a question of sensation and pleasure, of law and interdiction, but also of the true and the false.

Human rights are not just cultural or legal constructions, as fashionable western relativists are fond of claiming. They are universal values. To deny the benefits of the new regime of rights to other cultures is to patronise them in a way that is reminiscent of the colonial era. If the new regime on torture is good enough for the US, who can say that it is not good for everyone?

For what are they all in their high conceit, When man in the bush with God may meet?

If I find in myself a desire which no experience in this world can satisfy, the most probable explanation is that I was made for another world.

There is no social entity with a good that undergoes some sacrifice for its own good. There are only individual people, different individual people, with their own individual lives. Using one of these people for the benefit of others, uses him and benefits the others. Nothing more.

The power of the people and the power of reason are one.

That man, I declare, is happy whom nothing makes less strong than he is; he keeps to the heights, leaning upon none but himself; for one who sustains himself by any prop may fall.

Ever, as before, does Madness remain a mysterious-terrific, altogether infernal boiling-up of the Nether Chaotic Deep, through this fair-painted Vision of Creation, which swims thereon, which we name the Real.

It is a waste of energy to be angry with a man who behaves badly, just as it is to be angry with a car that won't go. The difference is that you can compel your car to go to a garage, but you cannot compel Hitler to go to a psychiatrist.

The man of virtue makes the difficulty to be overcome his first business, and success only a subsequent consideration.

When I happen to be busy, I never give a moment's thought to the "meaning" of anything, particularly of whatever it is I am doing. A proof that the secret of everything is in action and not abstention, that fatal cause of consciousness.

Make sure that your religion is a matter between you and God only.

Every person is an end in themselves. That's universal. To respect that leads to flourishing. Not respecting it in extremes leads to unnecessary death.

Absurd, irreducible; nothing - not even a profound and secret delirium of nature - could explain it. Obviously I did not know everything, I had not seen the seeds sprout, or the tree grow. But faced with this great wrinkled paw, neither ignorance nor knowledge was important: the world of explanations and reasons is not the world of existence. A circle is not absurd, it is clearly explained by the rotation of a straight segment around one of its extremities. But neither does a circle exist. This root, on the other hand, existed in such a way that I could not explain it. Reflections on a chestnut tree root.

Giving then to matter all the properties which philosophy knows it has, or all that atheism ascribes to it, and can prove, and even supposing matter to be eternal, it will not account for the system of the universe or of the solar system, because it will not account for motion, and it is motion that preserves it. When, therefore, we discover a circumstance of such immense importance, that without it the universe could not exist, and for which neither matter, nor any, nor all, the properties of matter can account, we are by necessity forced into the rational and comfortable belief of the existence of a cause superior to matter, and that cause man calls, God.

Money is therefore not only the object but also the fountainhead of greed.

Macaulay is like a book in breeches...He has occasional flashes of silence, that make his conversation perfectly delightful.

Perhaps the best hope for the future of mankind is that ways will be found of increasing the scope and intensity of sympathy.

Good bye, proud world! I'm going home; Thou art not my friend; I am not thine.

Of all the ways whereby children are to be instructed, and their manners formed, the plainest, easiest, and most efficacious, is, to set before their eyes the examples of those things you would have them do, or avoid; which, when they are pointed out to them, in the practice of persons within their knowledge, with some reflections on their beauty and unbecomingness, are of more force to draw or deter their imitation, than any discourses which can be made to them.

An American cannot converse, but he can discuss, and his talk falls into a dissertation. He speaks to you as if he was addressing a meeting; and if he should chance to become warm in the discussion, he will say "Gentlemen" to the person with whom he is conversing.

The guiding question of Marx's analysis was, How does capitalist society supply its members with the necessary use-values? And the answer disclosed a process of blind necessity, chance, anarchy and frustration. The introduction of the category of use-value was the introduction of a forgotten factor, forgotten, that is, by the classical political economy which was occupied only with the phenomenon of exchange value. In the Marxian theory, this factor becomes an instrument that cuts through the mystifying reification of the commodity world.

Can the children of the bridechamber mourn, as long as the bridegroom is with them? but the days will come, when the bridegroom shall be taken from them, and then shall they fast. No man putteth a piece of new cloth unto an old garment, for that which is put in to fill it up taketh from the garment, and the rent is made worse. Neither do men put new wine into old bottles: else the bottles break, and the wine runneth out, and the bottles perish: but they put new wine into new bottles, and both are preserved.

I appeal to the philosophers of all countries to unite and never again mention Heidegger or talk to another philosopher who defends Heidegger. This man was a devil. I mean, he behaved like a devil to his beloved teacher, and he has a devilish influence on Germany. ... One has to read Heidegger in the original to see what a swindler he was.

'Form' or 'figure' is space limited by boundaries. Space has necessarily 'three' dimensions, length, breadth, depth; and no ethers which cannot be resolved into these.

Now a man need not be very conversant in the writings of Chymists to observe, in how Laxe, Indefinite, and almost Arbitrary Senses they employ the Terms of Salt, Sulphur and Mercury; of which I could never find that they were agreed upon any certain Definitions or setled Notions; not onely differing Authors, but not unfrequently one and the same, and perhaps in the same Book, employing them in very differing senses.
