"The improver of natural knowledge absolutely refuses to acknowledge authority, as such. For him, skepticism is the highest of duties; blind faith the one unpardonable sin"

This quote by Thomas Huxley speaks with the value of skepticism in the pursuit of knowledge. He suggests that those who seek to enhance natural knowledge needs to refuse to accept authority as a source of reality. Rather, they must depend on skepticism as a method to examine the credibility of any claims. Blind faith, on the other hand, is seen as an unforgivable sin. This is since it includes accepting something without questioning it, which can lead to incorrect beliefs and an absence of progress. Huxley's quote motivates us to believe critically and to question the info we are presented with, instead of simply accepting it without question. This is an essential lesson for anyone who seeks to improve their understanding of the world.
