[5] Members of SAT are involved in socialist, anarchist, peace, trade union, anti-nationalist, feminist and environmental activities, among others.
The following declaration of aims became part of the Statute at the foundation of SAT in 1921, and remains valid to this day: "a) to utilise the international language Esperanto for the class aims of the worldwide working class; b) to promote mutual relations among members in the best and most worthy way possible, in order to instill in them a strong sense of human solidarity; c) to instruct, educate and enlighten the members in such a way as to make them the most capable and best of the so-called internationalists; d) to serve as an intermediary in relations among organisations using other languages but having aims analogous to those of SAT; e) to be an intermediary and supporter in the creation of an Esperanto literature consisting both of translations and original texts, and which reflects the ideal of our association."
In 1928 it was further clarified in the following addendum: "SAT, an educational and cultural organisation rather than an overtly political one, tries to induce its members to be understanding and tolerant of the political and philosophical schools or systems that lie at the base of the various workers' parties that are oriented toward class struggle and of trade-union movements; it seeks, by means of comparison of facts and ideas and by means of free discussion, to enable its members to avoid the dogmatisation of the teachings they encounter in their particular milieus.
In short, SAT constantly applies a rationally elaborated language on a worldwide scale in order to aid in the creation of intellects that think rationally and are able to compare accurately, understand correctly and assess ideas, theses and tendencies in such a way as to render them capable of electing independently the path they believe most direct or most expedient to the end of liberating their class and guiding the human race towards a level of civilisation and culture that is as advanced as possible."
The decision-making structure of SAT is, in theory, close to the organisational base, to the extent that all congress decisions should become valid only after a referendum.
The main feature of these meetings is the visit of Esperanto-speaking lecturers from abroad (e.g. from Cuba, Germany, the Netherlands, Belgium, and other countries).
SAT's publishing cooperative also produces a variety of books, some of them of an educational nature, such as the Plena Ilustrita Vortaro, the most comprehensive Esperanto dictionary, as well as socially engaged literary works.
