"I seem to be thinking rationally again in the style that is characteristic of scientists. However, this is not entirely a matter of joy as if someone returned from physical disability to good physical health"

This quote by John Forbes Nash, Jr. speaks with the concept of gaining back mental clearness and stability. Nash is expressing his relief at being able to think logically once again, in the way that is characteristic of scientists. However, he also acknowledges that this is not completely a cause for pleasure, as if someone had recovered from handicap to good physical health. This recommends that Nash has actually experienced a period of psychological instability, and is now eased to be able to believe clearly again. The quote speaks to the concept of mental health being simply as essential as physical health, and the difficulty of recovering from mental illness. Nash's words are a suggestion that mental health should be taken seriously, and that healing is possible.
