secularists do not sanctify any group, person, or book as if it and it alone has sole custody of the truth. Instead, secular people sanctify the truth wherever it may reveal itself—in ancient fossilized bones, in images of far-off galaxies, in tables of statistical data, or in the writings of various human traditions. This commitment to the truth underlies modern science, which has enabled humankind to crack the atom, decipher the genome, track the evolution of life, and understand the history of humanity itself.
