Science is, above all, a search for understanding based on a primacy of reason and evidence, with all findings subject to revision in accord with further evidence or more comprehensive explanation. The highest achievement in science is to discover a new or better understanding that can extend or replace an existing one.
The other major systems of organized understanding are ideology and religion. In these systems, understanding derives from what is deemed to be revealed truth, which is unethical even to question. Reason and evidence are subordinated to a supporting role that’s restricted to selected examples that accord with belief. The highest achievement here is not to discover truth, as that is accepted to be known with absolute certainty, but rather to defend such belief from any questioning and to maintain it without change or doubt, regardless of any and all reason and evidence that does not support it.
