Famous quotes containing the words hour and/or direction:
“Around, the night drops swiftly down
Its veils; does not condemn
Or praise the different actions done.
The hour that strikes across the town
Caresses all and injures none
As sleep approaches them.”
—Philip Larkin (1922–1986)
“That reality is ‘independent’ means that there is something in every experience that escapes our arbitrary control. If it be a sensible experience it coerces our attention; if a sequence, we cannot invert it; if we compare two terms we can come to only one result. There is a push, an urgency, within our very experience, against which we are on the whole powerless, and which drives us in a direction that is the destiny of our belief.”
—William James (1842–1910)
