Having once hung out with wordsmiths at the bar in a previous life, it's true, there is a good period of time where their brains are on fire and are some of the best raconteurs going. In fact when I think of my literary hero, Dylan Thomas, who pissed his life away in a pint bottle, he seemed to have no problem at all maintaining his genius for a good stretch of time while four sheets to the wind. But with all of them there is a tipping point where what was once wildly entertaining just becomes plain sad.
Lovers and madmen have such seething brains,
Such shaping fantasies, that apprehend
More than cool reason ever comprehends.
The lunatic, the lover and the poet
Are of imagination all compact:
One sees more devils than vast hell can hold,
That is, the madman: the lover, all as frantic,
Sees Helen's beauty in a brow of Egypt:
The poet's eye, in fine frenzy rolling,
Doth glance from heaven to earth, from earth to heaven;
And as imagination bodies forth
The forms of things unknown, the poet's pen
Turns them to shapes and gives to airy nothing
A local habitation and a name.
Such tricks hath strong imagination,
That if it would but apprehend some joy,
It comprehends some bringer of that joy;
Or in the night, imagining some fear,
How easy is a bush supposed a bear!
