The most immutable barrier in nature is between one man's thoughts and another's. — William James. American philosopher and psychologist (1842–1910)
The greatest discovery of my generation is that a human being can alter his life by altering his attitudes of mind.
There is only one thing a philosopher can be relied upon to do, and that is to contradict other philosophers.
Human beings, by changing the inner attitudes of their minds, can change the outer aspects of their lives.
