A fact, in science, is not a mere fact, but an instance.
It has often and confidently been asserted, that man’s origin can never be known: but ignorance more frequently begets confidence than does knowledge: it is those who know little, and not those who know much, who so positively assert that this or that problem will never be solved by science.
Science adjusts its views based on what’s observed;
Faith is the denial of observation so that belief can be preserved.
