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
Science is simply common sense at its best.
Interpretation
Science enhances our natural instinct for observation and reasoning.
This quote by Thomas Huxley suggests that the foundation of scientific inquiry lies in our innate ability to apply common sense, observation, and logical reasoning. It implies that science is not just a complex set of rules and concepts, but a refined application of the fundamental principles of thinking that we all possess, urging us to recognize the value of curiosity and rational thought in understanding the world around us.
In practice
During a science fair, I quoted Huxley to emphasize the importance of observation in experiments.

If you take 100 breast-cancer samples, 100 types of cancer have 100 different hallmarks of mutated genes. You could be nihilistic and say, 'Oh, God, we'll never be able to tackle this!' But there are deep, systematic, organizational principles at work in all that diversity.
All physical systems can be thought of as registering and processing information, and how one wishes to define computation will determine your view of what computation consists of.
We can allow satellites, planets, suns, universe, nay whole systems of universes, to be governed by laws, but the smallest insect, we wish to be created at once by special act.
For anyone inclined to caricature environmental history as 'environmental determinism,' the contrasting histories of the Dominican Republic and Haiti provide a useful antidote. Yes, environmental problems do constrain human societies, but the societies' responses also make a difference.
All illnesses have some heredity contribution. It's been said that genetics loads the gun and environment pulls the trigger.
That is the way of the scientist. He will spend thirty years in building up a mountain range of facts with the intent to prove a certain theory; then he is so happy with his achievement that as a rule he overlooks the main chief fact of all-that all his accumulation proves an entirely different thing.
