“A theory is only as good as its assumptions. If the premises are false, the theory has no real scientific value. The only scientific criterion for judging the validity of a scientific theory is a confrontation with the data of experience.”

“I claim that the success of current scientific theories is no miracle. It is not even surprising to the scientific (Darwinist) mind. For any scientific theory is born into a life of fierce competition, a jungle red in tooth and claw. Only the successful theories survive—the ones which in fact latched onto the actual regularities in nature.”

“The philosophy of science is concerned with how you decide if a scientific finding is correct or true. You have to establish criteria to determine if the finding or theory is valid. Validity is a fundamental problem in the philosophy of science, but the fundamental problem in the philosophy of scientific administration is the question of value.”

Alvin M. Weinberg (1915–2006) American nuclear physicist

Two scientific activities are equally valid if they achieve results that are true. Now, how do you decide which activity is more valuable? The question of value is the basic question that the scientific administrator asks so that decisions can be made about funding priorities. <br class="br"> Interview http://www.ornl.gov/info/ornlreview/rev28-1/text/wbgbar.htm by Bill Cabage and Carolyn Krause for the ORNL Review (April 1995).

“Evangelical atheists preach the need for a scientific view of things, but a settled view does not go with scientific method. If we know anything it is that most of the theories that prevail at any one time are false. Scientific theories are not components of a world-view but tools we use to tinker with the world.”

“The conventional Big Bang theory does not say anything about what caused the expansion. It really is only a theory about the aftermath of a bang. In the scientific version of the Big Bang, the universe starts with everything already expanding, with no explanation of how that expansion started… So the Scientific version of the Big Bang theory is not really a theory of a bang, it's really a theory of the aftermath of a bang.”

“A theory can never be proven absolutely true, therefore there is no end to scientific endeavor. A true scientific theory is always open to be disproved, and the burden of proof is continually placed on the scientist.”

“To say that prediction is the purpose of a scientific theory is to confuse means with ends. It is like saying that the purpose of a spaceship is to burn fuel. … Passing experimental tests is only one of many things a theory has to do to achieve the real purpose of science, which is to explain the world.”
