Amidst the vicissitudes of the earth's surface, species cannot be immortal, but must perish, one after another, like the individuals which compose them. There is no possibility of escaping from this conclusion.
Charles LyellRead
When the aggregate amount of solid matter transported by rivers in a given number of centuries from a large continent, shall be reduced to arithmetical computation, the result will appear most astonishing to those...not in the habit of reflecting how many of the mightiest of operations in nature are effected insensibly, without noise or disorder.
Interpretation
The quote highlights the vast and often unnoticed impacts of natural processes over time.
Charles Lyell's quote emphasizes the significance of geological processes such as erosion and sediment transport by rivers, suggesting that many profound changes in nature occur subtly and gradually, without drawing attention to themselves. It serves to remind us that some of the most powerful natural phenomena unfold quietly and require thoughtful reflection to appreciate their magnitude and impact on the landscape and environment.
In practice
In a speech about environmental conservation, one might use this quote to illustrate the importance of recognizing gradual changes in nature.
Amidst the vicissitudes of the earth's surface, species cannot be immortal, but must perish, one after another, like the individuals which compose them. There is no possibility of escaping from this conclusion.
Never was there a dogma more calculated to foster indolence, and to blunt the keen edge of curiosity, than the assumption of the discordance between the former and the existing causes of change.
The question now at issue, whether the living species are connected with the extinct by a common bond of descent, will best be cleared up by devoting ourselves to the study of the actual state of the living world, and to those monuments of the past in which the relics of the animate creation of former ages are best preserved and least mutilated by the hand of time.
Science is the tool of the Western mind and with it more doors can be opened than with bare hands.
To set foot on the soil of the asteroids, to lift by hand a rock from the Moon, to observe Mars from a distance of several tens of kilometers, to land on its satellite or even on its surface, what can be more fantastic? From the moment of using rocket devices a new great era will begin in astronomy: the epoch of the more intensive study of the firmament.
An alleged scientific discovery has no merit unless it can be explained to a barmaid.
Nothing has tended more to retard the advancement of science than the disposition in vulgar minds to vilify what they cannot comprehend.
We should've asked China to be a portion of the space station. We should've worked out ways that we can... just give away the technology that we have that puts things up into space, with cooperation up above the atmosphere that's needed to help each other.
In the end, a theory is accepted not because it is confirmed by conventional empirical tests, but because researchers persuade one another that the theory is correct and relevant.
