"DATA:
I have a question, sir. What is death?
PICARD:
You've picked probably the most difficult of all questions, Data.
Some explain it by inventing gods wearing their own form... and argue that the purpose of the entire universe is to maintain themselves in their present form in an Earth-like garden which will give them pleasure through all eternity. And at the other extreme, assuming that is an "extreme," are those who prefer the idea of our blinking into nothingness with all our experiences, hopes and dreams only an illusion.
DATA:
Which do you believe?
PICARD:
Considering the marvelous complexity of our universe, its clockwork perfection, its balances of this against that... matter, energy, gravitation, time, dimension, pattern, I believe our existence must mean more than a meaningless illusion. I prefer to believe that my and your existence goes beyond Euclidian and other "practical" measuring systems... and that, in ways we cannot yet fathom, our existence is part of a reality beyond what we understand now as reality."
