Leg Quotes (13 quotes)

A leg of mutton is better than nothing,
Nothing is better than Heaven,
Therefore a leg of mutton is better than Heaven.
Aphorism 21 in Notebook C (1772-1773), as translated by R.J. Hollingdale in Aphorisms (1990). Reprinted as The Waste Books (2000), 35.

I always keep two legs going, with one trying to reach ahead.

I can say, if I like, that social insects behave like the working parts of an immense central nervous system: the termite colony is an enormous brain on millions of legs; the individual termite is a mobile neurone.
In Late Night Thoughts on Listening to Mahler's Ninth Symphony(1984), 224. Note: Spelling “neurone&rdwuo; [sic].

I find in the domestic duck that the bones of the wing weigh less and the bones of the leg more, in proportion to the whole skeleton, than do the same bones in the wild duck; and this change may be safely attributed to the domestic duck flying much less, and walking more, than its wild parents.
From On the Origin of Species by Means of Natural Selection; or, The Preservation of Favoured Races in the Struggle for Life (1861), 17.

In 1906 I indulged my temper by hurling invectives at Neo-Darwinians in the following terms. “I really do not wish to be abusive [to Neo-Darwinians]; but when I think of these poor little dullards, with their precarious hold of just that corner of evolution that a blackbeetle can understand—with their retinue of twopenny-halfpenny Torquemadas wallowing in the infamies of the vivisector’s laboratory, and solemnly offering us as epoch-making discoveries their demonstrations that dogs get weaker and die if you give them no food; that intense pain makes mice sweat; and that if you cut off a dog’s leg the three-legged dog will have a four-legged puppy, I ask myself what spell has fallen on intelligent and humane men that they allow themselves to be imposed on by this rabble of dolts, blackguards, imposters, quacks, liars, and, worst of all, credulous conscientious fools.”
In Back to Methuselah: A Metabiological Pentateuch (1921), lxi

It was on the 25th November 1740 that I cut the first polyp. I put the two parts in a flat glass, which only contained water to the height of four to five lignes. It was thus easy for me to observe these portions of the polyp with a fairly powerful lens.
I shall indicate farther on the precautions I took in making my experiments on these cut polyps and the technique I adopted to cut them. It will suffice to say here that I cut the polyp concerned transversely, a little nearer the anterior than the posterior end. The first part was thus a little shorter than the second.
The instant that I cut the polyp, the two parts contracted so that at first they only appeared like two little grains of green matter at the bottom of the glass in which I put them—for green, as I have already said, is the colour of the first polyps that I possessed. The two parts expanded on the same day on which I separated them. They were very easy to distinguish from one another. The first had its anterior end adorned with the fine threads that serve the polyp as legs and arms, which the second had none.
The extensions of the first part was not the only sign of life that it gave on the same day that it was separated from the other. I saw it move its arms; and the next day, the first time I came to observe it, I found that it had changed its position; and shortly afterwards I saw it take a step. The second part was extended as on the previous day and in the same place. I shook the glass a little to see if it were still alive. This movement made it contract, from which I judged that it was alive. Shortly afterwards it extended again. On the following days I .’ saw the same thing.
Mémoires, pour servir à l'histoire d'un genre de polyps d'eau douce à bras en forme de cornes (1744), 7-16. Trans. John R. Baker, in Abraham Trembley of Geneva: Scientist and Philosopher 1710-1784 (1952), 31.

March 24, 1672. I saw the surgeon cut off the leg of a wounded sailor, the stout and gallant man enduring it with incredible patience without being bound to his chair as usual on such painful occasions. I had hardly courage enough to be present. Not being cut off high enough, the gangrene prevailed, and the second operation cost the poor creature his life.

Several times every day I observed the portions of the polyp with a magnifying glass. On the 4th December, that is to say on the ninth day after having cut the polyp, I seemed in the morning to be able to perceive, on the edges of the anterior end of the second part (the part that had neither head nor arms), three little points arising from those edges. They immediately made me think of the horns that serve as the legs and arms of the polyp. Nevertheless I did not want to decide at once that these were actually arms that were beginning to grow. Throughout the next day I continually observed these points: this excited me extremely, and awaited with impatience the moment when I should know with certainty what they were. At last, on the following day, they were so big that there was no longer any room for doubt that they were actually arms growing at the anterior extremity of this second part. The next day two more arms started to grow out, and a few days later three more. The second part thus had eight of them, and they were all in a short time as long as those of the first part, that is to say as long as those the polyp possessed before it was cut. I then no longer found any difference between the second part and a polyp that had never been cut. I had remarked the same thing about the first part since the day after the operation. When I observed them with the magnifying glass with all the attention of which I was capable, each of the two appeared perceptibly to be a complete polyp, and they performed all the functions that were known to me: they extended, contracted, and walked.

The centipede was happy quite, until a toad in fun
Said, 'Pray which leg goes after which?'
That work'd her mind to such a pitch,
She lay distracted in a ditch, considering how to run.
Pinafore Poems in Cassell's Weekly (1871). In Steven Vogel and Rosemary Anne Calvert Life's Devices (1988), 254.

The ten most important two-letter words in the English language: “if it is to be, it is up to me.” …
[Remember] the African parable of the sparrow who while flying through the sky heard a clap of thunder. He fell to the ground with his two little legs sticking up.
An eagle flying nearby saw the sparrow and asked “Hey, man, what’s happening?”
Replied the sparrow, “The sky is falling down.”
Mocked the eagle, “And what are you going to do, hold it up with those two little legs of yours?”
Replied the sparrow, “One does what one can with what one has.”
In address, to the Economic Club of Detroit (14 Jan 1990), 'Where Do We Go From Here?' on the massiechairs.com website.

We think of something that has four legs and wags its tail as being alive. We look at a rock and say it’s not living. Yet when we get down to the no man’s land of virus particles and replicating molecules, we are hard put to define what is living and what is non-living.
From interview, 'The Seeds of Life', in The Omni Interviews (1984), 4.

What can be more curious than that the hand of a man, formed for grasping, that of a mole for digging, the leg of the horse, the paddle of the porpoise, and the wing of the bat, should all be constructed on the same pattern?
In Origin of Species (1869), 516.

You cannot make a man by standing a sheep on its hind-legs. But by standing a flock of sheep in that position you can make a crowd of men.

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
