Currently the agriculture based on biotechnology is developing very dynamically, similarly to organic farming system. While considering different aspects of co-existence between GM and non-GM products (both conventional and the organic ones) it should be taken into account that no form of agriculture, neither conventional or organic nor the GMO based, should be excluded, and that the ability to maintain diversified agricultural production system is a precondition for providing a high degree of choice for consumers. In this context co-existence between GM and non-GM products has a big impact on both economic and market issues. However, a modified management system within the whole value supply chain is necessary to secure proper conditions for the co-existence between GM and non-GM products. In case of some food and feed products this chain has already been international in its scope. Although the co-existence between GM and non-GM products is determined by economic factors, the attitudes of consumers towards these products should be considered a key issue of development of value supply chains based on different agricultural systems.

In the 'Logical Investigations' Husserl claims that language and experience are structurally connected. But descriptions and reasons justifying this claim are not sufficient. For Husserl linguistic meanings are in fact the guidance for his descriptions of acts of cognition. The structural similarity of language and experience is therefore presupposed.

The author takes Merleau-Ponty's theory to show that the fact that we are living in the world of persistent things with constant features is a result of spontaneous normalization. There are some perceptual norms which decide on creation of typical subjective structures, and due to these structure we experience things as categorised or classified, for example like cats, dogs, trees, people, etc. Therefore Merleau-Ponty's theory can be helpful to explain the origin of the so-called prototype effect, and throw light on relation between the structures of experience and linguistic categories. Experience's orientation on optima, perception's constants, is evidenced in studies on sensory perception and also memory. Attractive, creating a class character of the constants (prototypes) has been emphasised. The prototypes created in the immediate experience create an intentional space, in which each interpretation takes place; they give a measure of all we perceive, see, create, think, etc. Dynamical character of the orientation on prototype makes a basis of the assumption: any actual prototype realisation is only relative, relational, and asymptotic, and linguistic categories (the conceptual structure of our mind) based on prototypes are relative also. The author emphasis that some more detail analyses would question a need of sharp distinction of linguistic and extra-linguistic knowledge, because regularities of categorisation processes, manifested in the meanings of terms denoting natural kinds, are the regularities of the perceptual processes and language. In this way the role of language as one and only determinant of the structure of experience may be limited.
