ERNEST

EVOLUTIONIST: A "trial and error" method that keeps what works.
PRAGMATIC: Knowledge is used to fulfill goals and satisfactions: "Meaning is use".
SELF-ORIENTED: An "unsupervised learning" that may however use pedagogical situations.
LEARNING: A knowledge acquisition that participates to the agent's development.
CONSTRUCTIVIST: as opposed to "Platonist", knowledge is not "discovered" but "constructed".
BOTTOM-UP: higher-level goals are constructed to better fulfill lower-level inborn satisfactions.
