A
meta-meme which confers
resistance to a wide variety of
memes (and their
sociotypes), without conferring
meme-allergies. In its purest form, tolerance allows its host to be repeatedly exposed to rival memes, even
intolerant rivals, without active
infection or meme-allergic reaction. Tolerance is a central
co-meme in a wide variety of
schemes, particularly "
liberalism", and "
democracy". Without it, a scheme will often become
exo-toxic and confer meme-allergies on its hosts.
Since schemes compete for finite belief-space, tolerance is not necessarily a virtue, but it has co-evolved in the ideosphere in much the same way as co-operation has evolved in biological ecosystems.
