Everything in nature is the result of fixed laws.
Charles DarwinRead
One general law, leading to the advancement of all organic beings, namely, multiply, vary, let the strongest live and the weakest die.
Interpretation
Darwin's quote highlights the principle of natural selection where organisms adapt and evolve, leading to survival of the fittest.
This quote by Charles Darwin encapsulates the core concept of natural selection, which posits that in nature, organisms that can adapt to their environment are more likely to survive and reproduce. This process leads to the gradual evolution of species as they multiply and vary over generations, while those that cannot adapt face extinction. It underscores the importance of adaptability and resilience in the natural world.

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
I don't expect that the million will ever be won, simply because there is no confirming evidence for any paranormal claims to date.
It is not a simple matter to differentiate unsuccessful from successful experiments. . . .[Most] work that is finally successful is the result of a series of unsuccessful tests in which difficulties are gradually eliminated.
If your economy grows [by] 4 percent, you ought to reduce child mortality 4 percent.
The shelves of many evangelicals are full of books that point out the flaws in evolution, discuss it only as a theory, and almost imply that there's a conspiracy here to avoid the fact that evolution is actually flawed. All of those books, unfortunately, are based upon conclusions that no reasonable biologist would now accept.
Science, as everyone knows, is responsible, moderate, unsentimental, and otherwise good.
I often say that when you can measure what you are speaking about, and express it in numbers, you know something about it; but when you cannot measure it, when you cannot express it in numbers, your knowledge is of a meagre and unsatisfactory kind.
