which confers resistance
to a wide variety of meme
s (and their sociotype
s), 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 scheme
s, 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.
