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.

When we see the shadow on our images, are we seeing the time 11 minutes ago on Mars? Or are we seeing the time on Mars as observed from Earth now? It's like time travel problems in science fiction. When is now; when was then?
The scientist who yields anything to theology, however slight, is yielding to ignorance and false pretenses, and as certainly as if he granted that a horse-hair put into a bottle of water will turn into a snake.
Physics filled me with awe, put me in touch with a sense of original causes. Physics brought me closer to God. That feeling stayed with me throughout my years in science. Whenever one of my students came to me with a scientific project, I asked only one question, 'Will it bring you nearer to God?'
When, however, the lay public rallies round an idea that is denounced by distinguished but elderly scientists and supports that idea with great fervor and emotion - the distinguished but elderly scientists are then, after all, probably right.
