The most important thing about science is values

Abstract

ABSTRACT Science is the search for truth about the observable world. But it rests on values. The only thing that can be discovered by observation is the immediate here and now. Otherwise, knowledge about the observable world is based on hearsay, spoken or recorded, about others' observations. Apart from small and fleeting observations, science rests on trust. Our scientific lives and scientific knowledge depend on choosing who and what to trust. Since we can meet only a few scientists at best, we have to decide whether to trust science as an institution. Science is a good bet because its aim is to create truth, perhaps posthumously; truth is its end as well as its means. In today's world, science is vitally important as a check and balance on democratic power and an object lesson for decision-makers. To do good, honest, science is to support democracy in the face of populism.
