Famous quotes containing the words optical, mark and/or sense:
“People who have realized that this is a dream imagine that it is easy to wake up, and are angry with those who continue sleeping, not considering that the whole world that environs them does not permit them to wake. Life proceeds as a series of optical illusions, artificial needs and imaginary sensations.”
—Alexander Herzen (1812–1870)

Near where the charter’d Thames does flow,
And mark in every face I meet
Marks of weakness, marks of woe.”
—William Blake (1757–1827)
“Books, the oldest and the best, stand naturally and rightfully on the shelves of every cottage. They have no cause of their own to plead, but while they enlighten and sustain the reader his common sense will not refuse them. Their authors are a natural and irresistible aristocracy in every society, and, more than kings or emperors, exert an influence on mankind.”
—Henry David Thoreau (1817–1862)
