Nowhere in space will we rest our eyes upon the familiar shapes of trees and plants, or any of the animals that share our world. Whatsoever life we meet will be as strange and alien as the nightmare creatures of the ocean abyss, or of the insect empire whose horrors are normally hidden from us by their microscopic scale.
It is a good principle in science not to believe any 'fact'---however well attested---until it fits into some accepted frame of reference. Occasionally, of course, an observation can shatter the frame and force the construction of a new one, but that is extremely rare. Galileos and Einsteins seldom appear more than once per century, which is just as well for the equanimity of mankind.
Interpretation
What this quote means
Scientific principles require that facts be contextualized within existing theories, but groundbreaking observations can challenge and reshape those frameworks.
This quote emphasizes the importance of context in scientific understanding, suggesting that facts should not be accepted in isolation but rather need to be evaluated within a pre-existing theoretical framework. It also highlights the rarity of revolutionary thinkers, like Galileo and Einstein, whose discoveries compel society to re-examine and expand that framework, ultimately leading to significant advancements in knowledge.
