Weeds Quotes

A Man of Knowledge like a rich Soil, feeds
If not a world of Corn, a world of Weeds.
In Poor Richard's Almanack (1739).

Here are a few things to keep in mind the next time ants show up in the potato salad. The 8,800 known species of the family Formicidae make up from 10% to 15% of the world's animal biomass, the total weight of all fauna. They are the most dominant social insect in the world, found almost everywhere except in the polar regions. Ants turn more soil than earthworms; they prune, weed and police most of the earth's carrion. Among the most gregarious of creatures, they are equipped with a sophisticated chemical communications system. To appreciate the strength and speed of this pesky invertebrate, consider that a leaf cutter the size of a man could run repeated four-minute miles while carrying 750 lbs. of potato salad.
From book review, 'Nature: Splendor in The Grass', Time (3 Sep 1990).

If Darwin were alive today the insect world would delight and astound him with its impressive verification of his theories of the survival of the fittest. Under the stress of intensive chemical spraying the weaker members of the insect populations are being weeded out… . Only the strong and fit remain to defy our efforts to control them.
Science quotes on:  |  Astound (3)  |  Chemical (72)  |  Control (93)  |  Charles Darwin (284)  |  Defy (5)  |  Delight (51)  |  Effort (94)  |  Entomology (5)  |  Impressive (11)  |  Insect (57)  |  Intensive (7)  |  Population (71)  |  Remain (77)  |  Spray (4)  |  Strong (47)  |  Survival Of The Fittest (34)  |  Theory (582)  |  Verification (20)  |  Weak (36)

City Aphorisms, Second Selection (1985).
Science quotes on:  |  Difference (208)  |  Flower (65)  |  Know (321)  |  Nature (1029)

Nothing is so beautiful as spring—
When weeds in wheels, shoot long and lovely and lush;...
'Spring' (1877), reprinted in Gerard Manley Hopkins and Michael White (ed.) Some Poems of Gerard Manley Hopkins, (1945), 7.
Science quotes on:  |  Beauty (171)  |  Long (95)  |  Lovely (4)  |  Lush (2)  |  Shoot (10)  |  Spring (47)  |  Wheel (13)

Parkinson's Law is a purely scientific discovery, inapplicable except in theory to the politics of the day. It is not the business of the botanist to eradicate the weeds. Enough for him if he can tell us just how fast they grow.
Parkinson's Law or the Pursuit of Progress (1958), 15.
Science quotes on:  |  Botanist (16)  |  Business (71)  |  Discovery (591)  |  Enough (6)  |  Eradication (2)  |  Growth (111)  |  Law (418)  |  Parkinson’s Law (4)  |  Research (517)  |  Sufficiency (13)  |  Tell (67)  |  Theory (582)

Ploughing deep, your recipe for killing weeds, is also the recipe for almost every good thing in farming. … We now plough horizontally following the curvatures of the hills and hollows, on the dead level, however crooked the lines may be. Every furrow thus acts as a reservoir to receive and retain the waters, all of which go to the benefit of the growing plant, instead of running off into streams … In point of beauty nothing can exceed that of the waving lines and rows winding along the face of the hills and vallies.
In letter (17 Apr 1813) from Jefferson at Monticello to Charles Willson Peale. Collected in The Jefferson Papers: 1770-1826 (1900), 178-180.

Revenge is a kind of wild justice; which the more man’s nature runs to, the more ought law to weed it out.

The logical feebleness of science is not sufficiently borne in mind. It keeps down the weed of superstition, not by logic but by slowly rendering the mental soil unfit for its cultivation.
In 'Science and Spirits', Fragments of Science for Unscientific People (1871), 409.
Science quotes on:  |  Cultivation (23)  |  Feebleness (2)  |  Logic (187)  |  Mental (57)  |  Rendering (6)  |  Science (1699)  |  Soil (51)  |  Sufficiency (13)  |  Superstition (50)  |  Unfit (9)

We cannot hope to fill the schools with persons of high intelligence, for persons of high intelligence simply refuse to spend their lives teaching such banal things as spelling and arithmetic. Among the teachers male we may safely assume that 95% are of low mentality, el se they would depart for more appetizing pastures. And even among the teachers female the best are inevitably weeded out by marriage, and only the worst (with a few romantic exceptions) survive.

Weeds function as an unseen tax on the crop harvest.
From 'War on Weeds', Science (19 Apr 1946), 103, No. 2677, 465.

What is a weed? A plant whose virtues have not yet been discovered.
From Lecture delivered at the Old South Church (30 Mar 1878), published as a booklet, Fortune of the Republic (1878), 3.
Science quotes on:  |  Discover (115)  |  Plant (173)  |  Virtue (55)

What is a weed? I have heard it said that there are sixty definitions. For me, a weed is a plant out of place.
In Flowering Earth (1939), 156. Note that this definition was in use before Peattie was born, for example “the true definition of a weed is ‘a plant out of place’” appears in Alex Brown, The Coffee Planter's Manual (1880), 121.
Science quotes on:  |  Definition (152)  |  Place (111)  |  Plant (173)

What would the world be, once bereft
Of Wet and Wilderness? Let them be left,
O let them be left, wilderness and wet;
Long live the weeds and the wilderness yet.
'Inversnaid' (1881), reprinted in Gerard Manley Hopkins and Michael White (ed.) Some Poems of Gerard Manley Hopkins, (1945), 16, stanza 4.
Science quotes on:  |  Left (13)  |  Wet (5)  |  Wilderness (28)


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
