The document discusses the evolution of the concept of lifelong education from adult education. It notes that adult education has been at the heart of developing lifelong education as a theoretical framework and providing flexible learning opportunities. The key contributions of adult education to lifelong education include developing a theory of andragogy to help maturing learners, providing non-traditional study programs that are self-directed and convenient for part-time learners, and retraining teachers to serve as facilitators for self-directed learners. Adult education is seen as central to advancing the goal of preparing all individuals to be engaged in lifelong learning and inquiry.
