It has long been observed that an atheist has no just reason for endeavoring conversions; and yet none harass those minds which they can influence with more importunity of solicitation to adopt their opinions. In proportion as they doubt the truth of their own doctrines, they are desirous to gain the attestation of another understanding, and industriously labor to win a proselyte; and eagerly catch at the slightest pretense to dignify their sect with a celebrated name.

The point
Atheists paradoxically work to convert others despite doubting their own doctrines, seeking validation through others' assent to their beliefs.
