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
Nothing great in science has ever been done by men, whatever their powers, in whom the divine afflatus of the truth-seeker was wanting.
Interpretation
True scientific achievements require a genuine desire to seek out the truth.
Thomas Huxley's quote emphasizes that greatness in science is not just about individual intelligence or capability, but rather about an intrinsic motivation and passion for uncovering the truth. Without the divine spark of curiosity and dedication to seeking knowledge, even the most talented individuals may fail to make significant contributions to science.
In practice
In a classroom setting, a teacher could use this quote to inspire students to pursue their scientific interests passionately.

Why is there space rather than no space? Why is space three-dimensional? Why is space big? We have a lot of room to move around in. How come it's not tiny? We have no consensus about these things. We're still exploring them.
Humans are natural-born scientists. When we're born, we want to know why the stars shine. We want to know why the sun rises.
A theory which is not refutable by any conceivable event is non-scientific. Irrefutability is not a virtue of a theory (as people often think) but a vice.
It is foolish to claim, as some do, that emigration into space offers a long-term escape from Earth's problems. Nowhere in our solar system offers an environment even as clement as the Antarctic or the top of Everest.
The reality is the majority of us will not get off this planet. So the long run is, some kind of space exploration has to benefit us here on Earth.
