Ever since we crawled out of that primordial slime, that's been our unifying cry: "More light." Sunlight. Torchlight. Candlight. Neon. Incandescent. Lights that banish the darkness from our caves, to illuminate our roads, the insides of our refrigerators. Big floods for the night games at Soldier's field. Little tiny flashlight for those books we read under the covers when we're supposed to be asleep. Light is more than watts and footcandles. Light is metaphor... Light is knowledge. Light is life. Light is light.

I guess what I'm trying to say is I don't think you can measure life in terms of years. I think longevity doesn't necessarily have anything to do with happiness. I mean happiness comes from facing challenges and going out on a limb and taking risks. If you're not willing to take a risk for something you really care about, you might as well be dead.

It's no accident that the church and the graveyard stand side by side. The city of the dead sleeps encircled by the city of the living.

As a scientist, I am not sure anymore that life can be reduced to a class struggle, to dialectical materialism, or any set of formulas. Life is spontaneous and it is unpredictable, it is magical. I think that we have struggled so hard with the tangible that we have forgotten the intangible.

Trees like to have kids climb on them, but trees are much bigger than we are, and much more forgiving.

We hold in our hands, the most precious gift of all: Freedom. The freedom to express our art. Our love. The freedom to be who we want to be. We are not going to give that freedom away and no one shall take it from us!

Let's not kid ourselves. Whatever we diagnose, most patients, if they don't die, get well by themselves. Our job is mainly to try to make them feel better; do no harm.
