Probability Quotes

“I teach something called The Law of Probabilities, which says the more things you try, the more likely one of them will work. The more books you read, the more likely one of them will have an answer to a question that could solve the major problems of your life.. make you wealthier, solve a health problem, whatever it might be.”

“It is, I believe, justifiable to make the generalization that anything an organic chemist can synthesize can be made without him. All he does is increase the probability that given reactions will 'go.' So it is quite reasonable to assume that given sufficient time and proper conditions, nucleotides, amino acids, proteins, and nucleic acids will arise by reactions that, though less probable, are as inevitable as those by which the organic chemist fulfills his predictions. So why not self-duplicating virus-like systems capable of further evolution?”

“Some reasonable term ought to be allowed to enable aliens to get rid of foreign and acquire American attachments; to learn the principles and imbibe the spirit of our government; and to admit of a probability at least, of their feeling a real interest in our affairs.”

“If you trace back all those links in the chain that had to be in place for me to be here, the laws of probability maintain that my very existence is miraculous. But then after however many decades, less than a hundred years, they disburse and I cease to be. So while they're all congregated and coordinated to make me, then-and I speak her on behalf of all those trillions of atoms-I should really make the most of things.”

“The certainty that life cannot be long, and the probability that it will be much shorter than nature allows, ought to awaken every man to the active prosecution of whatever he is desirous to perform. It is true, that no diligence can ascertain success; death may intercept the swiftest career; but he who is cut off in the execution of an honest undertaking has at least the honour of falling in his rank, and has fought the battle, though he missed the victory.”

“The representatives of business interests are the men to start this enterprise among our people and bring them to a full realization of the very grave seriousness of this war, to make them feel that we are in this war to win, and the probability is that our entering this war is going to be the deciding factor, and that the burden of the success is going to rest upon the United States.”

“We know the laws of trial and error, of large numbers and probabilities. We know that these laws are part of the mathematical and mechanical fabric of the universe, and that they are also at play in biological processes. But, in the name of the experimental method and out of our poor knowledge, are we really entitled to claim that everything happens by chance, to the exclusion of all other possibilities?”

“Among all the occurrences possible in the universe the a priori probability of any particular one of them verges upon zero. Yet the universe exists; particular events must take place in it, the probability of which (before the event) was infinitesimal. At the present time we have no legitimate grounds for either asserting or denying that life got off to but a single start on earth, and that, as a consequence, before it appeared its chances of occurring were next to nil. ... Destiny is written concurrently with the event, not prior to it.”

“I am convinced that it is impossible to expound the methods of induction in a sound manner, without resting them upon the theory of probability. Perfect knowledge alone can give certainty, and in nature perfect knowledge would be infinite knowledge, which is clearly beyond our capacities. We have, therefore, to content ourselves with partial knowledge - knowledge mingled with ignorance, producing doubt.”

“The incomplete knowledge of a system must be an essential part of every formulation in quantum theory. Quantum theoretical laws must be of a statistical kind. To give an example: we know that the radium atom emits alpha-radiation. Quantum theory can give us an indication of the probability that the alpha-particle will leave the nucleus in unit time, but it cannot predict at what precise point in time the emission will occur, for this is uncertain in principle.”

“The office of science is not to record possibilities; but to ascertain what nature does ... As far as Darwinism deals with mere arguments of possibilities or even probabilities, without a basis of fact, it departs from the true scientific method and injures science, as most of the devotees of the new ism have already done.”

“Saudi Arabian oil production is at or very near its peak sustainable volume (if it did not, in fact peak almost 25 years ago), and is likely to go into decline in the very foreseeable future. There is only a small probability that Saudi Arabia will ever deliver the quantities of petroleum that are assigned to it in all the major forecasts of world oil production and consumption.”

“Further, the same Arguments which explode the Notion of Luck, may, on the other side, be useful in some Cases to establish a due comparison between Chance and Design: We may imagine Chance and Design to be, as it were, in Competition with each other, for the production of some sorts of Events, and may calculate what Probability there is, that those Events should be rather be owing to the one than to the other.”

“In some ways more painful is the fact that their experience appears to be fading from the collective memory of humankind. Having never experienced an atomic bombing, the vast majority around the world can only vaguely imagine such horror, and these days, John Hersey's Hiroshima and Jonathan Schell's The Fate of the Earth are all but forgotten. As predicted by the saying, 'Those who cannot remember the past are condemned to repeat it,' the probability that nuclear weapons will be used and the danger of nuclear war are increasing.”

“Without any doubt, the regularity which astronomy shows us in the movements of the comets takes place in all phenomena. The trajectory of a simple molecule of air or vapour is regulated in a manner as certain as that of the planetary orbits; the only difference between them is that which is contributed by our ignorance. Probability is relative in part to this ignorance, and in part to our knowledge.”

“The theory of probabilities is basically only common sense reduced to a calculus. It makes one estimate accurately what right-minded people feel by a sort of instinct, often without being able to give a reason for it.”

“Once we see, however, that the probability of life originating at random is so utterly minuscule as to make it absurd, it becomes sensible to think that the favorable properties of physics, on which life depends, are in every respect deliberate.... It is, therefore, almost inevitable that our own measure of intelligence must reflect higher intelligence -even to the limit of God.”

“A further aspect I should like to discuss is what I call the practice of infinite escape clauses. I believe we developed this practice to avoid facing the conclusion that the probability of self-reproducing state is zero. This is what we must conclude from classical quantum mechanical principles as Wigner demonstrated”

“Contemporary scholars have little explored the preconditions of genocide. Still less have they asked whether a society's weapons policy might be one of the institutional arrangements that contributes to the probability of its government engaging in some of the more extreme varieties of outrage. Though it is a long step between being disarmed and being murdered - one does not usually lead to the other - but it is nevertheless an arresting reality that not one of the principal genocides of the 20th century, and there have been dozens, has been inflicted on a population that was armed.”

“In a high tech world the cure for the tragic shortcomings and perilous fallacies of human intuition is education, but education in economics, evolutionary biology, probability and statistics - unfortunately most High School and College curricula have barely changed since Medieval times!”

“Most, probably, of our decisions to do something positive, the full consequences of which will be drawn out over many days to come, can only be taken as the result of animal spirits-a spontaneous urge to action rather than inaction, and not as the outcome of a weighted average of quantitative benefits multiplied by quantitative probabilities.”

“My favourite fellow of the Royal Society is the Reverend Thomas Bayes, an obscure 18th-century Kent clergyman and a brilliant mathematician who devised a complex equation known as the Bayes theorem, which can be used to work out probability distributions. It had no practical application in his lifetime, but today, thanks to computers, is routinely used in the modelling of climate change, astrophysics and stock-market analysis.”

“People are entirely too disbelieving of coincidence. They are far too ready to dismiss it and to build arcane structures of extremely rickety substance in order to avoid it. I, on the other hand, see coincidence everywhere as an inevitable consequence of the laws of probability, according to which having no unusual coincidence is far more unusual than any coincidence could possibly be.”

“It may be laid down as a general rule, that their confidence in and obedience to a government, will be commonly proportioned to the goodness or badness of its administration . . . . Various reasons have been suggested in the course of these papers, to induce a probability that the general government will be better administered than the particular governments.”
