There is no genius without a mixture of madness.

No great genius has ever existed without some touch of madness.

There is no genius free from some tincture of madness

Genius always gives its best at first; prudence, at last.

Nothing is so wretched or foolish as to anticipate misfortunes. What madness is it to be expecting evil before it comes.

The display of grief makes more demands than grief itself. How few men are sad in their own company.
