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
Reply when questioned on the safety of the polio vaccine he developed: It is safe, and you can't get safer than safe.
If you think about the impact of climate change, [it should be how] a doctor would deal with the problem. A scientific hypothesis is tested to absolute destruction, but medicine can't wait. If a doctor sees a child with a fever, he can't wait for [endless] tests. He has to act on what is there. The risk of delay is so enormous that we can't wait until we are absolutely sure the patient is dying.
Rising carbon price is essential to 'decarbonize' the economy - to remove the nation towards the era beyond fossil fuels.
Without theory, practice is but routine born of habit. Theory alone can bring forth and develop the spirit of invention. ... [Do not] share the opinion of those narrow minds who disdain everything in science which has not an immediate application. ... A theoretical discovery has but the merit of its existence: it awakens hope, and that is all. But let it be cultivated, let it grow, and you will see what it will become.
Economic and technical imperatives - not any preconceived directives - will keep propelling the process of energy transition.
My practise as a scientist is atheistic. That is to say, when I set up an experiment I assume that no god, angel, or devil is going to interfere with its course; and this assumption has been justified by such success as I have achieved in my professional career. I should therefore be intellectually dishonest if I were not also atheistic in the affairs of the world. And I should be a coward if I did not state my theoretical views in public.
