[M]y suggestion is that every independent Atheist group adopt the same, single motto: "Veritas Omnia Vincit", which in its antiquity is not copyrighted, and can speak for any godless/atheist philosophy. Having a UNIFYING image to present to the religious world would give each and every group, Atheist Alliance, Secular Humanism, Freethought Society, far more perceived power, strength in numbers, yet allowing for individuality necessary to different regional turns of mind.
All the different christian groups can sport the same "cross" as an insignia. VERITAS OMNIA VINCIT, declaring that Truth Conquers All, is a non-combative, clearly stated stand on integrity. ... I sincerely believe that it is counterproductive for atheists to lack a visible identity, even though each atheist bases the rationalist philosophy of life on different experiences in different cultures. However, Veritas Omnia Vincit applies.
Do you think that atheists need to be united by a single slogan? If so, would the above work or do you think that there might be something better out there? Add your thoughts to the comments here or join the ongoing discussion in the forum.
