Book: Atheism in Five Minutes
Chapter: 2. What Is the Difference Between "Atheism", "Agnosticism", "Nonreligion" and "Secular"?
Blurb:
This chapter introduces three terms—“agnosticism,” “nonreligion,” and “secular”—which are entangled with the concept of “atheism” before mapping their similarities and differences in different contexts. The take-home message throughout should be that difference is in the eye of the beholder and depends on who is utilizing the terms and for what purpose.
