Gravel Quotes (3 quotes)
[Overfishing—] it’s not just that we’re taking too many out, it’s how we’re doing it. We are wiping out their nurseries, … [because some huge boats] … bottom trawl … [with] nets that 50 years ago you’d have to lift when you came to coral reefs or rocks or nooks and crannies. Now they’re so sophisticated and so heavy, the equipment, and the boat’s so powerful they can just drag right over the coral reefs and the rocks and the nooks and crannies, and turn them into a gravel pit. … The trouble is those are the nurseries. That’s where the little fish hide and get bigger and get big enough for us to eat.
From transcript of PBS TV interview by Tavis Smiley (28 Mar 2011).
About thirty years ago there was much talk that geologists ought only to observe and not theorise; and I well remember some one saying that at this rate a man might as well go into a gravel-pit and count the pebbles and describe the colours. How odd it is that anyone should not see that all observation must be for or against some view if it is to be of any service!
Letter to Henry Fawcett (18 Sep 1861). In Charles Darwin, Francis Darwin, Albert Charles Seward, More Letters of Charles Darwin (1903), Vol. 1, 195.
No anatomist ever discovered a system of organization, calculated to produce pain and disease; or, in explaining the parts of the human body, ever said, this is to irritate; this is to inflame; this duct is to convey the gravel to the kidneys; this gland to secrete the humour which forms the gout: if by chance he come at a part of which he knows not the use, the most he can say is, that it is useless; no one ever suspects that it is put there to incommode, to annoy, or torment.
The Principles of Moral and Political Philosophy (1785), Vol. 1, 79.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
