A Quote by John Maynard Keynes

It has been pointed out already that no knowledge of probabilities, less in degree than certainty, helps us to know what conclusions are true, and that there is no direct relation between the truth of a proposition and its probability. Probability begins and ends with probability.

It was our use of probability theory as logic that has enabled us to do so easily what was impossible for those who thought of probability as a physical phenomenon associated with "randomness". Quite the opposite; we have thought of probability distributions as carriers of information.

Edwin Thompson Jaynes

Probability and expectation are not the same. Its probability and probability times the pay off.

Nassim Nicholas Taleb

According to theism, if a universe is to have any probability of existing, this probability is dependent upon God's beliefs, desires and creative acts. But the Hartle-Hawking probability is not dependent on any supernatural considerations; Hartle and Hawking do not sum over anything supernatural in their path integral derivation of the probability amplitude.

Quentin Smith

Probability is expectation founded upon partial knowledge. A perfect acquaintance with all the circumstances affecting the occurrence of an event would change expectation into certainty, and leave nether room nor demand for a theory of probabilities.

George Boole

It follows that the word probability, in its mathematical acceptance, has reference to the state of our knowledge of the circumstances under which an event may happen or fail. With the degree of information we possess concerning the circumstances of an event, the reason we have to think that it will occur, or, to use a single term, our expectation of it will vary. Probability is the expectation founded upon partial knowledge.

George Boole

If an event can be produced by a number n of different causes, the probabilities of the existence of these causes, given the event (prises de l'événement), are to each other as the probabilities of the event, given the causes: and the probability of each cause is equal to the probability of the event, given that cause, divided by the sum of all the probabilities of the event, given each of the causes.

Pierre-Simon Laplace

The grand assertion is that you must see the world through probability and that probability is the only guide you need.

Dennis Lindley

The probability that we will get into a car accident is a million times higher than the probability we will suffer as a result of terrorist act.

Pavel Durov

Scientists do not believe in fundamental and absolute certainties. For the scientist, certainty is never an end, but a search; not the ordering of certainty, but its exploration. For the scientist, certainty represents the highest degree of probability.

Ashley Montagu

The true Logic for this world is the Calculus of Probabilities, which takes account of the magnitude of the probability.

James Clerk Maxwell

The risk of an investment is described by both the probability and the potential amount of loss. The risk of an investment-the probability of an adverse outcome-is partly inherent in its very nature. A dollar spent on biotechnology research is a riskier investment than a dollar used to purchase utility equipment. The former has both a greater probability of loss and a greater percentage of the investment at stake.

Seth Klarman

All knowledge resolves itself into probability. ... In every judgment, which we can form concerning probability, as well as concerning knowledge, we ought always to correct the first judgment deriv'd from the nature of the object, by another judgment, deriv'd from the nature of the understanding.

David Hume

The source of Pyrrhonism comes from failing to distinguish between a demonstration, a proof and a probability. A demonstration supposes that the contradictory idea is impossible; a proof of fact is where all the reasons lead to belief, without there being any pretext for doubt; a probability is where the reasons for belief are stronger than those for doubting.

Andrew Michael Ramsay

From principles is derived probability, but truth or certainty is obtained only from facts.

Tom Stoppard

If you get rid of emotion for a minute and think about the threat of terrorism statistically, it's not even there. The probability that you will slip on a wet floor in your bathroom and die is a thousand times higher than the probability of you dying as a result of terrorism.

Pavel Durov

Many modern philosophers claim that probability is relation between an hypothesis and the evidence for it.
