Everything in nature is the result of fixed laws.
Charles DarwinRead
On seeing the marsupials in Australia for the first time and comparing them to placental mammals: “An unbeliever . . . might exclaim 'Surely two distinct Creators must have been at work'”
Interpretation
Darwin suggests that the existence of marsupials and placental mammals may imply a complex design in nature.
In this quote, Charles Darwin reflects on the diversity of life he observed, particularly the differences between marsupials and placental mammals in Australia. He implies that such distinct forms of reproductive biology might lead one to believe in multiple creators rather than a single evolutionary process, highlighting the complexity and wonders of natural selection and adaptation.
In practice
In a lecture on evolutionary biology, I would quote Darwin to illustrate the complexity of life.
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
What we observe as material bodies and forces are nothing but shapes and variations in the structure of space.
Based on the science, you can make somewhat clear statements: The number of people who can survive on six hours of sleep without impairment is zero.
The trouble is that the hockey stick graph become an icon and deniers reckoned if they could smash the icon, the whole concept of global warming would be destroyed with it.
Science predicts that many different kinds of universe will be spontaneously created out of nothing. It is a matter of chance which we are in.
I love science, and it pains me to think that so many are terrified of the subject or feel that choosing science means you cannot also choose compassion, or the arts, or be awed by nature. Science is not meant to cure us of mystery, but to reinvent and reinvigorate it.
There could be more to the universe than the three dimensions we are familiar with. They are hidden from us in some way, perhaps because they're tiny or warped. But even if they're invisible, they could affect what we actually observe in the universe.
