“Wisdom tolerates blustered opinions, the better to dismiss them later with discovery.”

“Sketches of mad skies spilling stars caught in spiraling gyres, diagrams for constructing sextants tall as a man and armillary spheres to mimic the motion of the cosmos. He decides that he must have all of it, that he will cram the little observatory with maps and charts, clocks and compasses, and instruments for bringing the sky nearer.”

“Is this not the very thing that drives an adventurous man to navigate uncharted oceans, to traverse continents and mountains, to pilot virgin estuaries and hidden coves—this promise of inscribing a name steadfast upon what he finds? There are few parcels of earth left to be claimed; yet even as the known world shrinks, the heavens grow ever more infinite. An explorer of the skies need never leave his home or fret over the swiftness of other expeditions; he might give whatever name he chooses to any new thing that wanders into his view.”

“But if watching the sky is to be his duty, how should he begin? Now and then he has spotted one of the five bright planets or recognized a constellation, but he knows little about the turning of the heavens. When he contemplates the great distances between this and that, and the vast multitude of solitary objects spread over the celestial dome, he cannot fathom how one goes about searching for what is yet unknown.”

“It is only the sudden and unpredictable appearance of comets that spoils the immutable celestial sphere.”

“It is one of the great blessings of youth, this guiltlessness, the source of gentle sleep and peaceful days.”

“The basis of English law is as simple as this: If you would know the future’s shape, look to the past.”

“The heavens are too immense, too beautiful and varied, to fit into the mind of any one deity; the murmured creeds of fathers and sons are no match for the astronomer’s gasp.”

“Her calculations have always held the utmost accuracy, but mathematics alone will not be enough to guide her; she must learn to trust in chance and, if need be, in accident.”

“What has been his cause for searching the heavens day and night, for testing the limit of his reach hour by hour like a man trapped inside an expanding balloon? The reasons were as various as the days they consumed: to grasp the workings of the universe, to find something more beyond earth's fretful compass, to put his name to a discovery and secure fame's immortality, to be able to point to a map and proclaim simply: here I am.”
