Albert Camus wrote that the only serious question is whether to kill yourself or not.
Tom Robbins wrote that the only serious question is whether time has a beginning and an end.
Camus clearly got up on the wrong side of the bed, and Robbins must have forgotten to set the alarm.
There is only one serious question. And that is:
Who knows how to make love stay?
Answer me that and I will tell you whether or not to kill yourself.
Answer me that and I will ease your mind about the beginning and the end of time.
Answer me that and I will reveal to you the purpose of the moon.

-Tom Robbins, from Still Life With Woodpecker
