It is wrong for a man to say that he is certain of the objective truth of any proposition unless he can produce evidence which logically justifies that certainty.
Thomas HuxleyRead
Every great advance in natural knowledge has involved the absolute rejection of authority.
Interpretation
True scientific progress requires questioning and discarding established authorities.
In this quote, Thomas Huxley emphasizes the importance of skepticism in the pursuit of knowledge. He suggests that significant advancements in science have often come from challenging and rejecting accepted beliefs, rather than merely accepting them based on authority. This appeal to critical thinking encourages individuals to explore and validate ideas independently, leading to deeper understanding and innovation.
In practice
In a classroom discussion about the Scientific Revolution, this quote can inspire students to think critically about established beliefs.

It is the first duty of a hypothesis to be intelligible.
Of the few innocent pleasures left to men past middle life, the jamming of common sense down the throats of fools is perhaps the keenest.
There is no science in this world like physics. Nothing comes close to the precision with which physics enables you to understand the world around you. It's the laws of physics that allow us to say exactly what time the sun is going to rise. What time the eclipse is going to begin. What time the eclipse is going to end.
Carbon has this genius of making a chemically stable, two-dimensional, one-atom-thick membrane in a three-dimensional world. And that, I believe, is going to be very important in the future of chemistry and technology in general.
A physicist is just an atom's way of looking at itself.
There are no black holes in the sense of regimes from which light can't escape to infinity.
Tiny differences in input could quickly become overwhelming differences in output.... In weather, for example, this translates into what is only half-jokingly known as the Butter- fly Effectβthe notion that a butterfly stirring the air today in Peking can transform storm systems next month in New York.
Imagine being able to predict and prevent cancer before it starts. If we gather the world's talent and expertise in a committed, targeted effort, great progress is possible.
