Cosmos

by Carl Sagan

The universe revealed by the relentless error-correcting mechanism of science was to him infinitely preferable to the untested assumptions of traditional belief.

For Carl, the “spiritual” had to be rooted in natural reality.

Nature does not reveal her mysteries once and for all. —Seneca, Natural Questions, Book 7, first century

The Cosmos is all that is or ever was or ever will be.
