to represent the life of a blade of grass

One of the essays in my 2nd year Typography class is FT Marinetti's  Distruction of Syntax.  I've always had mixed feelings about Marinetti.

Last year one of my students pulled a beautiful segment from it:

...to represent the life of a blade of grass, I say, 'Tomorrow I'll be greener.'

I feel I'd only spoil that with an image, so there it is. Isn't it lovely? This is the full quote for context: The imagination without strings, and words-in-freedom, will bring us to the essence of material. As we discover new analogies between distant and apparently contrary things, we will endow them with an ever more intimate value. Instead of humanizing animals, vegetables, and minerals (an outmoded system) we will be able to animalize, vegetize, mineralize, electrify, or liquefy our style, making it live the life of material. For example, to represent the life of a blade of grass, I say, ‘Tomorrow I’ll be greener.’
