Taking into account the research conclusions in social and natural sciences, gastropoetics as a research method allows to examine a literary text in-depth revealing the causal relationships and nuances of the psychological portrayal of characters, as well as analyse semantic pluralism providing more diverse interpretation opportunities of a literary text. In Andrejs Upīts’s novel “Bread” (Maize, 1914) the portrayed passengers of the third class train wagon are a micromodel of Western society, where food, sharing the food or its denial precisely reveal the hierarchic structure of community and the differences in social stratification, as well as human behavioural principles, which are based on the tradition that has evolved over thousands of years and can also be cross-compared with the behavioural principles observable among animals. Other aspects include the social undermining of certain social groups, for instance, older people, children, foreigners, as well as the marginalisation of these groups denying them the freedom of choice or action, equal rights, etc. Upīts in his novel constructs a social situation of a small community, accurately revealing the hierarchic structure, as well as collaboration and relationship models of the community.
