By 1930, Estable developed The Plan Estable, which called for teaching the scientific method as a learning tool in primary school. Through Estable's plan, the scientific method was adopted into the curricula of Natural and Applied Sciences. That same year, Estable presided over the First International Congress of Biologists in Montevideo, as president of The Uruguayan Society of Biologists. In the 1930s, Estable was appointed professor of biology at schools of law and medicine. He also received an honorary degree from the
University of Santiago, Chile. In 1948, he presided over the first Latin American Scientists Congress, organized by
UNESCO and
WHO. In 1959, he was given the title of Honorary Professor of
Universidad de Montevideo. In 1962, he was awarded the
Legion of Honour, the highest French order of merit. In the same year, Italy awarded him an honorary position as a member of The Medical Academy of Rome. According to Estable, scientific research, artistic creation, or philosophical reflections should offer the possibility of living with dignity in civil society. Further, he proposed that the scientist, the artist, and the philosopher all fulfill essential societal and national functions. Therefore, it is the responsibility of the elected public officials to promote these professions and create adequate conditions for them to execute their work. == Personal life ==
