It is curious to reflect on how history repeats itself the world over. Why, I remember the same thing was done when I was a boy on the Mississippi River. There was a proposition in a township there to discontinue public schools because they were too expensive. An old farmer spoke up and said if they stopped the schools they would not save anything, because every time a school was closed a jail had to be built.
It's like feeding a dog on his own tail. He'll never get fat. I believe it is better to support schools than jails.

The Johns Hopkins University certifies that John Wentworth Doe does not know anything but Biochemistry. Please pay no attention to any pronouncements he may make on any other subject, particularly when he joins with others of his kind to save the world from something or other. However, he worked hard for this degree and is potentially a most valuable citizen. Please treat him kindly.

The power of mathematics rests on its evasion of all unnecessary thought and on its wonderful saving of mental operations.

There are two ways to slide easily through life; to believe everything or to doubt everything. Both ways save us from thinking.
