Fortress Quotes (4 quotes)

It so happens that the work which is likely to be our most durable monument, and to convey some knowledge of us to the most remote posterity, is a work of bare utility; not a shrine, not a fortress, not a palace, but a bridge.
Writing upon the opening of the Brooklyn Bridge, New York.
'The Bridge as a Monument', Harper's Weekly (26 May 1883), 27, 326. In David P. Billington, The Tower and the Bridge: The New Art of Structural Engineering (1983), 17.

No one in his senses, or imbued with the slightest knowledge of physics, will ever think that the earth, heavy and unwieldy from its own weight and mass, staggers up and down around its own center and that of the sun; for at the slightest jar of the earth, we would see cities and fortresses, towns and mountains thrown down.
Universae Naturae Theatrum (1597). In Dorothy Stimson, The Gradual Acceptance of the Copernican Theory of the Universe (1917), 45.

This sceptred isle,…
This fortress built by Nature for herself…
This precious stone set in the silver sea,
Which serves it in the office of a wall
Or as a moat defensive to a house,
Against the envy of less happier lands,
This blessed plot, this earth, this realm, this England.
In Richard II, Act 2, Scene 1.

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
