Everything in nature is the result of fixed laws.
Charles DarwinRead
I would give absolutely nothing for the theory of Natural Selection, if it requires miraculous additions at any one stage of descent.
Interpretation
Darwin expresses skepticism about Natural Selection if it relies on miraculous events during evolution.
In this quote, Charles Darwin emphasizes his belief in Natural Selection as a natural and gradual process, asserting that if it requires any miraculous interventions or additions at any point in the evolutionary history, then he would not value the theory. This reveals his commitment to empiricism and the idea that scientific explanations should be based on observable natural phenomena rather than supernatural or miraculous events.
In practice
During a science lecture on evolution, this quote can be used to emphasize the importance of empirical evidence.
Everything in nature is the result of fixed laws.
The highest possible stage in moral culture is when we recognize that we ought to control our thoughts.
I am quite conscious that my speculations run beyond the bounds of true science....It is a mere rag of an hypothesis with as many flaw[s] & holes as sound parts.
We cannot fathom the marvelous complexity of an organic being; but on the hypothesis here advanced this complexity is much increased. Each living creature must be looked at as a microcosm--a little universe, formed of a host of self-propagating organisms, inconceivably minute and as numerous as the stars in heaven.
I have called this principle, by which each slight variation, if useful, is preserved, by the term of Natural Selection.
we are always slow in admitting any great change of which we do not see the intermediate steps
[Bacteria are the] dark matter of the biological world [with 4 million mostly unknown species in a ton of soil].
Exxon, one of the companies that has spent tens of millions of dollars denying climate change, denying any responsibility to deal with, taking government subsidies on a massive scale, now their ads are all about, 'Oh, we want a clean future. We're looking at clean energy and all that stuff.'
Tell me why the stars do shine, Tell me why the ivy twines, Tell me what makes skies so blue, And I'll tell you why I love you. Nuclear fusion makes stars to shine, Tropisms make the ivy twine, Raleigh scattering make skies so blue, Testicular hormones are why I love you.
Working out another system to replace Newton's laws took a long time because phenomena at the atomic level were quite strange. One had to lose one's common sense in order to perceive what was happening at the atomic level.
We have no right to assume that any physical laws exist, or if they have existed up until now, that they will continue to exist in a similar manner in the future.
We know more about the movement of celestial bodies than about the soil underfoot.
