Famous quotes containing the words optical and/or pulse:
“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)
“While our pulse beats and we feel emotion, let us put off the business. Things will truly seem different to us when we have quieted and cooled down. It is passion that is in command at first, it is passion that speaks, it is not we ourselves.”
—Michel de Montaigne (1533–1592)
