We must reason in natural philosophy not from what we hope, or even expect, but from what we perceive.
Humphry DavyRead
Nothing is so dangerous to the progress of the human mind than to assume that our views of science are ultimate, that there are no mysteries in nature, that our triumphs are complete and that there are no new worlds to conquer.
Interpretation
The quote warns against the complacency that can come from believing we have fully understood science and nature.
Humphry Davy's quote emphasizes the importance of humility in the pursuit of knowledge. He cautions that when we assume our current scientific understanding is final, we close ourselves off to new discoveries and possibilities, stifling the progress of our intellect and the exploration of nature's mysteries. Acknowledging that there is always more to learn encourages continuous inquiry and advancement.
In practice
During a lecture on scientific progress, this quote can highlight the importance of ongoing research.
We must reason in natural philosophy not from what we hope, or even expect, but from what we perceive.
Every discovery opens a new field for investigation of facts, shows us the imperfection of our theories. It has justly been said, that the greater the circle of light, the greater the boundary of darkness by which it is surrounded.
The whole language of nature informs us, that in animated beings there is something above our powers of investigation; something which employs, combines, and arranges the gross elements of matter - a spark of celestial fire, by which life is kindled and preserved, and which, if even the instruments it employs are indestructible in their essence, must itself, of necessity, be immortal.
The progression of physical science is much more connected with your prosperity than is usually imagined. You owe to experimental philosophy some of the most important and peculiar of your advantages. It is not by foreign conquests chiefly that you are become great, but by a conquest of nature in your own country.
Geology, perhaps more than any other department of natural philosophy, is a science of contemplation. It requires no experience or complicated apparatus, no minute processes upon the unknown processes of matter. It demands only an enquiring mind and senses alive to the facts almost everywhere presented in nature. And as it may be acquired without much difficulty, so it may be improved without much painful exertion.
To me there never has been a higher source of honour or distinction than that connected with advances in science. I have not possessed enough of the eagle in my character to make a direct flight to the loftiest altitudes in the social world; and I certainly never endeavored to reach those heights by using the creeping powers of the reptile, who in ascending, generally chooses the dirtiest path, because it is the easiest.
Evolution is as much a fact as the heat of the sun.
Climate Change is a national security issue. We found that climate instability will lead to instability in geopolitics and impact American military operations around the world. People are saying they want to be perfectly convinced about climate science projections. But speaking as a soldier, we never have 100 percent certainty. If you wait until you have 100 percent certainty, something bad is going to happen on the battlefield.
There's no tradition of scientists knocking down the Sunday school door, telling the preacher, That might not necessarily be true. That's never happened. There're no scientists picketing outside of churches.
Computer science is no more about computers than astronomy is about telescopes.
I am not deeply involved in Australian politics but I know there are prime ministers, governments around the world who are not acting responsibly in relation to climate change.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
