"It is a mercy that we walk through the world half-blind to the reality of time and transience, or we would be walking through it in tears — through the immense cathedral of time that Earth is, with its neatly lined pews of geologic strata holding the history of life, which is the history of loss. And yet the very fact that any one life exists against the cosmic odds of eternal night and nothingness is miracle enough — a triumph of the possible over the probable, a concatenation of chemistry and chance gilded with wonder."  --Maria Popova
