The Veracity Principle
“The Veracity Principle. It is not possible to verify a scientific theory such that it provides absolute certainty for all time. A theory is instead accepted (or even tolerated), on the basis of its ability to survive the tests and meet additional criteria of simplicity, efficacy, utility, explanatory power and less rational, innately human measures such as beauty. Over time the theory becomes familiar and is accepted as ‘true’ or, at least, as possessing a high truth-likeness or verisimilitude. The scientists’ confidence or degree of belief in the theory grows. It is eventually absorbed into the common body of knowledge which forms the current ‘authorized’ version of empirical reality.”

System of Nature
“The present state of the system of nature is evidently a consequence of what it was in the preceding moment, and if we conceive of an intelligence that at a given instant comprehends all the relations of the entities of this universe, it could state the respective position, motions, and general affects of all these entities at any time in the past or future. Physical astronomy, the branch of knowledge that does the greatest honor to the human mind, gives us an idea, albeit imperfect, of what such an intelligence would be. The simplicity of the law by which the celestial bodies move, and the relations of their masses and distances, permit analysis to follow their motions up to a certain point; and in order to determine the state of the system of these great bodies in past or future centuries, it suffices for the mathematician that their position and their velocity be given by observation for any moment in time. Man owes that advantage to the power of the instrument he employs, and to the small number of relations that it embraces in its calculations. But ignorance of the different causes involved in the production of events, as well as their complexity, taken together with the imperfection of analysis, prevents our reaching the same certainty about the vast majority of phenomena. Thus there are things that are uncertain for us, things more or less probable, and we seek to compensate for the impossibility of knowing them by determining their different degrees of likelihood. So it was that we owe to the weakness of the human mind one of the most delicate and ingenious of mathematical theories, the science of chance or probability.”

Search For Truth
“The search for truth is rightly considered the essence of scientific activities, it appears as an important problem to find at least partial criteria of truth and to develop procedures that may enable us to ascertain or negate the truth (or at least the likelihood of truth).”
