Filament Quotes (4 quotes)

From thus meditating on the great similarity of the structure of the warm-blooded animals, and at the same time of the great changes they undergo both before and after their nativity; and by considering in how minute a portion of time many of the changes of animals above described have been produced; would it be too bold to imagine that, in the great length of time since the earth began to exist, perhaps millions of ages before the commencement of the history of mankind would it be too bold to imagine that all warm-blooded animals have arisen from one living filament, which THE GREAT FIRST CAUSE endued with animality, with the power of acquiring new parts, attended with new propensities, directed by irritations, sensations, volitions and associations, and thus possessing the faculty of continuing to improve by its own inherent activity, and of delivering down these improvements by generation to its posterity, world without end!
Zoonomia, Or, The Laws of Organic Life, in three parts (1803), Vol. 1, 397.

A noiseless, patient spider,
I mark’d, where on a little promontory, it stood, isolated;
Mark’d how, to explore the vacant, vast surrounding,
It launch’d forth filament, filament, filament, out of itself
Ever unreeling them—ever tirelessly speeding them.
In 'A Noiseless Patient Spider', Broadway: A London Magazine (1868), reprinted in Leaves of Grass (5th ed., 1871, 1888), 343.

It is therefore proper to acknowledge that the first filaments of the chick preexist in the egg and have a deeper origin, exactly as [the embryo] in the eggs of plants.

Men that looke no further than their outsides thinke health an appertinance unto life, and quarrell with their constitutions for being sick; but I that have examined the parts of man, and know upon what tender filaments that Fabrick hangs, doe wonder what we are not alwayes so; and considering the thousand dores that lead to death doe thanke my God that we can die but once.
Religio Medici (1642), Part I, Section 44. In L. C. Martin (ed.), Thomas Browne: Religio Medici and Other Works (1964), 42.

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
