What is life but the angle of vision? A man is measured by the angle at which he looks at objects. What is life but what a man is thinking of all day? This is his fate and his employer. Knowing is the measure of the man. By how much we know, so much we are.
Ralph Waldo Emerson (May 25, 1803 April 27, 1882) was a famous American essayist and one of America's most influential thinkers and writers.
