Summary
This quote suggests that atheism is more of a superficial belief or expression rather than a genuine conviction rooted in one's core values or beliefs. It implies that many individuals may claim to be atheists verbally, but their innermost beliefs or instincts may still harbor a sense of spirituality or a belief in something beyond the material world. In essence, it proposes that there may be a disparity between what someone claims to believe and what they truly hold in their heart.
