There's a System?

What if this is all we get? What if this firefly's existence is really all that's been gifted to us, and when we blink out tomorrow, that's it. Eternity's simply a fairytale we tell ourselves to stay sane. And because it paints a pretty picture; takes the sting out of 'the end.' Maybe there's no real point to anything we do beyond scratching out the most basic of subsistences. What's the point of building the tallest building, the fastest car, the deadliest missile? And the point of society creating this ideal and then creating the people to fulfill it? I mean, cosmically speaking, what's it all about?

And more importantly, if this is really all we've got, why am I inside reading 'Culture and Social Thought in the Depression Years,' when it's a gorgeous day outside?
