Somewhere, something incredible is waiting to be known.

Since, in the long run, every planetary society will be endangered by impacts from space, every surviving civilization is obliged to become spacefaring — not because of exploratory or romantic zeal, but for the most practical reason imaginable: staying alive.

Except in pure mathematics, nothing is known for certain (although much is certainly false).

We live on a mote of dust suspended in a sunbeam

If we are not able to ask skeptical questions, to interrogate those who tell us that something is true, to be skeptical of those in authority, then, we are up for grabs for the next charlatan (political or religious) who comes rambling along.

Nothing disturbs me more than the glorification of stupidity.

My wonder button is being pushed all the time.
