Navigate Quotes (3 quotes)

One will weave the canvas; another will fell a tree by the light of his ax. Yet another will forge nails, and there will be others who observe the stars to learn how to navigate. And yet all will be as one. Building a boat isn’t about weaving canvas, forging nails, or reading the sky. It’s about giving a shared taste for the sea, by the light of which you will see nothing contradictory but rather a community of love.
From the French, “Celui-là tissera des toiles, l’autre dans la forêt par l’éclair de sa hache couchera l’arbre. L’autre, encore, forgera des clous, et il en sera quelque part qui observeront les étoiles afin d’apprendre à gouverner. Et tous cependant ne seront qu’un. Créer le navire ce n’est point tisser les toiles, forger les clous, lire les astres, mais bien donner le goût de la mer qui est un, et à la lumière duquel il n’est plus rien qui soit contradictoire mais communauté dans l’amour.” In Citadelle (1948), Sect. 75, 687. An English edition was published as “Wisdom of the Sands.” The translation in the subject quote is given the website quoteinvestigator.com which discusses how it may have been paraphrased anonymously to yield the commonly seen quote as “If you want to build a ship, don’t recruit the men to gather the wood, divide the work and give orders. Instead, teach them to yearn for vast and endless sea.”

The most advanced nations are always those who navigate the most.
In 'Society and Solitude: Civilization', The Prose Works of Ralph Waldo Emerson (1870, 1880), Vol. 3, 14.

There is more evidence to prove that saltiness [of the sea] is due to the admixture of some substance ... It is this stuff which makes salt water heavy (it weighs more than fresh water) and thick. The difference in consistency is such that ships with the same cargo very nearly sink in a river when they are quite fit to navigate in the sea. This circumstance has before now caused loss to shippers freighting their ships in a river. That the thicker consistency is due to an admixture of something is proved by the fact that if you make strong brine by the admixture of salt, eggs, even when they are full, float in it. It almost becomes like mud; such a quantity of earthy matter is there in the sea.
[Aristotle recognised the different density of fresh (river) or salty (sea) water. He describes an experiment using an egg (which sinks in fresh water) that floats in a strong brine solution.]

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
