If ever a title explained the book, this certainly fits the bill:
The Best Nonreligious Quotes Ever by Christine Pierce and Kevin Reedy is a compilation of quotations on the topics of hope, love, purpose, kindness, death, etc.
Unlike other quotation collections on those subjects, none of the statements in this book mention or refer to God.
It’s refreshing to see intelligent and memorable lines that you can cite in a speech or essay — all of which are secular.
Even better is that the collection quotes outspoken atheists (Richard Dawkins, Salman Rushdie) and atheist bloggers (Greta Christina, Noell Hyman) along with the usual celebrities (Ralph Waldo Emerson, Aristotle, Warren Buffett).
This is a book that’ll be even better in a couple years when a newer, larger edition comes out.
In the meantime, it’s a nice little collection of several hundred quotations. You can see some samples here as well as more about the authors — two people who ended up with Master’s degrees in Theology before deciding they were non-religious
