The highest possible stage in moral culture is when we recognize that we ought to control our thoughts.
Charles DarwinRead
Everything in nature is the result of fixed laws.
Interpretation
Nature operates according to consistent and predictable principles.
In this quote, Charles Darwin emphasizes that all phenomena in nature are governed by immutable laws. This perspective encourages a scientific understanding of the natural world, where everything from the smallest organisms to the largest ecosystems develops according to observable rules, highlighting the importance of studying these laws to comprehend the complexities of life.
In practice
In a science class, when discussing the principles of ecology, this quote can highlight the importance of understanding natural 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
I am not the least afraid to die
Nature abhors a vacuum, and if I can only walk with sufficient carelessness I am sure to be filled.
The greatest delight which the fields and woods minister is the suggestion of an occult relation.
This is suicidal... our home is the biosphere. That's a very thin layer of air, water and land where all life exists. It's fixed, it can't grow, and yet we cling to this idea that the economy can grow forever. And it must. Well, it can't.
what sets wilderness apart in the modern day is not that it's dangerous (it's almost certainly safer than any town or road) or that it's solitary (you can, so they say, be alone in a crowded room) or full of exotic animals (there are more at the zoo). it's that five miles out in the woods you can't buy anything.
He got out of bed and peeped through the blinds. To the east and opposite to him gardens and an apple-orchard lay, and there in strange liquid tranquility hung the morning star, and rose, rilling into the dusk of night the first grey of dawn. The street beneath its autumn leaves was vacant, charmed, deserted.
The industrial processes in use today were developed at a time when no one had to consider what the environmental impact was. Who cared? But making ecological concerns matter to a company's bottom line will help it do the research and development that will reinvent everything we buy.
