Re-examine all that you have been told. - Walt Whitman

A perfect writer would make words sing, dance, kiss, do the male and female act, bear children, weep, bleed, rage, stab, steal, fire cannon, steer ships, sack cities, charge with cavalry or infantry, or do anything that man or woman or the natural powers can do.

"We descend upon you and all things — we arrest you all;
We realize the soul only by you, you faithful solids and fluids;
Through you color, form, location, sublimity, ideality;
Through you every proof, comparison, and all the suggestions and determinations of ourselves.

You have waited, you always wait, you dumb, beautiful ministers! you novices!
We receive you with free sense at last, and are insatiate henceforward;
Not you any more shall be able to foil us, or withhold yourselves from us;
We use you, and do not cast you aside — we plant you permanently within us;
"We fathom you not — we love you — there is perfection in you also;
You furnish your parts toward eternity;
Great or small, you furnish your parts toward the soul.

We don't read and write poetry because it's cute. We read and write poetry because we are members of the human race. And the human race is filled with passion. So medicine, law, business, engineering... these are noble pursuits and necessary to sustain life. But poetry, beauty, romance, love... these are what we stay alive for.
