A man’s worth is measured by the worth of what he values.
— Marcus Aurelius
Straight and Crooked Thinking
Straight and Crooked Thinking is a most marvellous book, written by
Robert H. Thouless, and first published in 1930. I wholeheartedly recommend it, and think it should be required reading for young people the world over, especially for those who have trouble reading past some language that may be considered to have 'aged like milk'.
