　　科学”theory” and “fact”
　　when it comes to scienceour wishes and desires ultimately yield to the stubbornness of facts--by whichI mean empirical scientific evidenceand the laws and principles of the physical world. Admittedly,in many cases it is difficult to distinguish between scientific"fact" and mere "theory." History is replete with examples of whatwere considered at one time to be facts, but later disproved as incorrecttheories. Yet it is telling that many such obsolete theories were based on thesubjective inclinations, desires, and wishes of theorists and of the societiesin which the theorists lived. For example, the notions of an Earth-centereduniverse and of linear time and space were both influenced by religiousnotions--that is, by human wishes and passions. As our factual knowledge increased, such theories ultimately giveway.
