“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.

Context: 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.
