River Quotes (5)
Eratosthenes declares that it is no longer necessary to inquire as to the cause of the overflow of the Nile, since we know definitely that men have come to the sources of the Nile and have observed the rains there.
Proclus on Plato Timaeus, Vol. 1, 121.8-11 (Diehl). Quoted in Morris R. Cohen and I. E. Drabkin, A Sourcebook in Greek Science (1948), 383.
Once established, an original river advances through its long life, manifesting certain peculiarities of youth, maturity and old age, by which its successive stages of growth may be recognized without much difficulty.
'The Rivers and Valleys of Pennsylvania', The National Geographic Magazine, 1889, 1, 203.
The proof given by Wright, that non-adaptive differentiation will occur in small populations owing to 'drift', or the chance fixation of some new mutation or recombination, is one of the most important results of mathematical analysis applied to the facts of neo-mendelism. It gives accident as well as adaptation a place in evolution, and at one stroke explains many facts which puzzled earlier selectionists, notably the much greater degree of divergence shown by island than mainland forms, by forms in isolated lakes than in continuous river-systems.
Evolution: The Modern Synthesis (1942), 199-200.

The sea is the source of water and the source of wind; for neither would blasts of wind arise in the clouds and blow out from within them, except for the great sea, nor would the streams of rivers nor the rain-water in the sky exist but for the sea ; but the great sea is the begetter of clouds and winds and rivers.
Quoted in Arthur Fairbanks (ed. And trans.), The First Philosophers of Greece (1898), 69, fragment 11.
Who, of men, can tell
That flowers would bloom, or that green fruit would swell
To melting pulp, that fish would have bright mail,
The earth its dower of river, wood, and vale,
The meadows runnels, runnels pebble-stones,
The seed its harvest, or the lute its tones,
Tones ravishment, or ravishment its sweet,
If human souls did never kiss and greet?
That flowers would bloom, or that green fruit would swell
To melting pulp, that fish would have bright mail,
The earth its dower of river, wood, and vale,
The meadows runnels, runnels pebble-stones,
The seed its harvest, or the lute its tones,
Tones ravishment, or ravishment its sweet,
If human souls did never kiss and greet?
Endymion (1818), bk. 1, l. 835-842. In John Barnard (ed.), John Keats. The Complete Poems (1973), 129.
