Whoever wishes to acquire a deep acquaintance with Nature must observe that there are analogies which connect whole branches of science in a parallel manner, and enable us to infer of one class of phenomena what we know of another. It has thus happened on several occasions that the discovery of an unsuspected analogy between two branches of knowledge has been the starting point for a rapid course of discovery.
Interpretation
Understanding nature requires recognizing connections between different scientific fields.
William Stanley Jevons emphasizes the importance of observing analogies across various branches of science. By identifying these connections, one can leverage knowledge from one area to gain insights into another, often leading to significant discoveries and advancements in understanding natural phenomena.
In practice
In a scientific conference discussing the relationship between physics and biology, a speaker might use this quote to emphasize interdisciplinary collaboration.
It is clear that Economics, if it is to be a science at all, must be a mathematical science ... simply because it deals with quantities... As the complete theory of almost every other science involves the use of calculus, so we cannot have a true theory of Economics without its aid.
Value is the most invincible and impalpable of ghosts, and comes and goes unthought of, while the visible and dense matter remains as it was.
If two scientists are giving their papers at a symposium, and one of them is just naturally better at talking to the public or talking to a group of people, that scientist is liable to get more attention - in fact, I'm told that they do get more attention - than the one who's a little more stiff about it. Well, that's not good for science.
Crash programs fail because they are based on theory that, with nine women pregnant, you can get a baby in a month.
The history of science shows that theories are perishable. With every new truth that is revealed we get a better understanding of Nature and our conceptions and views are modified.
The notion of superhumans is using bioengineering and artificial intelligence to upgrade human abilities. If they use the power to change themselves, to change their own minds, their own desires, then we have no idea what they will want to do.
I was taught over and over again that the accumulation of random mutations led to evolutionary change - led to new species. I believed it until I looked for evidence.
Thanks to farm subsidies, the fine collaboration between agribusiness and Congress, soy, corn and cattle became king. And chicken soon joined them on the throne. It was during this period that the cycle of dietary and planetary destruction began, the thing we're only realizing just now.
