Swift Quotes (10 quotes)

But in nothing are swifts more singular than in their early retreat. They retire, as to the main body of them, by the tenth of August, and sometimes a few days sooner: and every straggler invariably withdraws by the twentieth, while their congeners, all of them, stay till the beginning of October; many of them all through that month, and some occasionally to the beginning of November. This early retreat is mysterious and wonderful, since that time is often the sweetest season in the year. But, what is more extraordinary, they begin to retire still earlier in the most southerly parts of Andalusia, where they can be no ways influenced by any defect of heat; or, as one might suppose, defect of food. Are they regulated in their motions with us by failure of food, or by a propensity to moulting, or by a disposition to rest after so rapid a life, or by what? This is one of those incidents in natural history that not only baffies our searches, but almost eludes our guesses I
In Letter to Daines Barrington, (28 Sep 1774), in The Natural History and Antiquities of Selborne (1789), 278.

Have you ever observed a humming-bird moving about in an aerial dance among the flowers—a living prismatic gem that changes its colour with every change of position— … its exquisite form, its changeful splendour, its swift motions and intervals of aλrial suspension, it is a creature of such fairy-like loveliness as to mock all description.
In Green Mansions: A Romance of the Tropical Forest (1916),

I was taught that the way of progress is neither swift nor easy.

Men fear thought as they fear nothing else on earth more than ruin more even than death. Thought is subversive and revolutionary, destructive and terrible, thought is merciless to privilege, established institutions, and comfortable habit. Thought looks into the pit of hell and is not afraid. Thought is great and swift and free, the light of the world, and the chief glory of man.

Nature! … She creates needs because she loves action. Wondrous! that she produces all this action so easily. Every need is a benefit, swiftly satisfied, swiftly renewed.—Every fresh want is a new source of pleasure, but she soon reaches an equilibrium.
As quoted by T.H. Huxley, in Norman Lockyer (ed.), 'Nature: Aphorisms by Goethe', Nature (1870), 1, 10.

Our plenteous streams a various race supply,
The bright-eye Perch with fins of Tyrian dye,
The silver Eel, in shining volumes roll’d,
The yellow Carp, in scales bedropp’d with gold,
Swift Trouts, diversified with crimson stains,
And Pykes, the Tyrants of the wat’ry plains.
In poem, 'Windsor Forest', collected in The Works of Mr. Alexander Pope (1718), 51.

See with what force yon river’s crystal stream
Resists the weight of many a massy beam.
To sink the wood the more we vainly toil,
The higher it rebounds, with swift recoil.
Yet that the beam would of itself ascend
No man will rashly venture to contend.
Thus too the flame has weight, though highly rare,
Nor mounts but when compelled by heavier air.
De Rerum Natura, second book, as quoted in translation in Thomas Young, A Course of Lectures on Natural Philosophy and the Mechanical Arts (1845), 12.

Talent, in difficult situations, strives to untie knots, which genius instantly cuts with one swift decision.

The swift metamorphosis and the onward march of civilization, sweeping ever westward and transforming and taming our wilderness, fills us with a strange regret, and we rejoice that parts of that wilderness will yet remain to us unchanged

Carl Sagan Thumbnail 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. (1987) -- Carl Sagan
