Summary
This quote suggests that atheism demonstrates a certain level of intellectual strength, but it has its limitations. While rejecting the existence of a higher being can showcase independent thinking, it implies that there may be a limit to the intellectual rigor imposed by complete atheism. This could imply that acknowledging the possibility of something beyond what is comprehensible might require a different kind of strength or open-mindedness. Thus, the quote proposes that atheism displays mental strength up to a certain extent, but beyond that, other perspectives might be necessary for deeper understanding.
