Madness is somewhere between chaos and having a dream.

Madness is something rare in individuals — but in groups, parties, peoples, and ages, it is the rule.

When life itself seems lunatic, who knows where madness lies? Perhaps to be too practical may be madness. To surrender dreams, this may be madness ...Maddest of all is to see life as it is and not as it should be.

Madness is to think of too many things in succession too fast, or of one thing too exclusively.
