Everything in nature is the result of fixed laws.
Charles DarwinRead
Why, if species have descended from other species by insensibly fine gradations, do we not everywhere see innumerable transitional forms.
Interpretation
Darwin questions the lack of observable transitional forms if evolution occurs through gradual changes.
In this quote, Charles Darwin is reflecting on the theory of evolution, specifically addressing a potential challenge to the idea that species evolve gradually from one form to another. He points out that if this gradual change is true, one would expect to find many transitional forms in the fossil record, yet their absence raises important questions about the completeness of our understanding of evolutionary history.
In practice

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
First, it is necessary to study the facts, to multiply the number of observations, and then later to search for formulas that connect them so as thus to discern the particular laws governing a certain class of phenomena. In general, it is not until after these particular laws have been established that one can expect to discover and articulate the more general laws that complete theories by bringing a multitude of apparently very diverse phenomena together under a single governing principle.
Evolution is a process of constant branching and expansion.
Scientific understanding is often beautiful, a profoundly aesthetic experience which gives pleasure not unlike the reading of a great poem.
Scientific theories tell us what is possible; myths tell us what is desirable. Both are needed to guide proper action.
We scientists have fantasies of being uniquely qualified to make great discoveries. Alas, reality is cruel: most of us are replaceable. For the vast majority of scientific contributions, if scientist X hadn't achieved it that year, scientist Y would have achieved the same result or something very similar soon thereafter.
It turns out your conscious mind - the part you think of as you - is really the smallest part of whatβs happening in your brain, and usually the last one in line to find out any information.
