Everything in nature is the result of fixed laws.
Charles DarwinRead
To suppose that the eye, with all its inimitable contrivances for adjusting the focus to different distances, for admitting different amounts of light, and for the correction of spherical and chromatic aberration, could have been formed by natural selection, seems, I freely confess, absurd in the highest possible degree.
Interpretation
Darwin expresses skepticism about the evolution of the eye through natural selection due to its complexity.
In this quote, Charles Darwin conveys his belief that the intricate design of the eye, with its various sophisticated features for focus, light adjustment, and correction of visual distortions, cannot reasonably be attributed to the process of natural selection. He finds the notion absurd, reflecting on the remarkable complexities of biological structures that challenge simplistic evolutionary explanations.
In practice
This quote can be used in a discussion about the intricacies of biological systems in a biology class.
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
C'este donc par l'étude des mathématiques, et seulement par elle, que l'on peut se faire une idée juste et approfondie de ce que c'est qu'une science.
As a physicist, I've always found cosmology to be a rational elixir; it distances me from ordinary concerns.
Each of these [bacterial] species are masterpieces of evolution. Each has persisted for thousands to millions of years. Each is exquisitely adapted to the environment in which it lives, interlocked with other species to form ecosystems upon which our own lives depend in ways we have not begun even to imagine.
It is the first duty of a hypothesis to be intelligible.
The Secretary of Hygiene or Physical Culture will be far more important in the cabinet of the President of the United States who holds office in the year 2035 than the Secretary of War.
We have this very clean picture of science, you know, these well-established rules with which we make predictions. But when you're really doing science, when you're doing research, you're at the edge of what we know.
