Special Issue of the journal Akadeemia dedicated to Juri Lotman

For human thought all that exists is that which falls into any of its languages. Thus, for instance, purely physiological processes such as sexual contact or the impact of alcohol on the organism represent physical and physiological realities. But it is precisely these examples which manifest an essential law: the more distant by its very nature this or that domain is from the sphere of culture, the more effort is applied to introduce it into this sphere.
