Ivan Illich said this quote
“ Schools are even less efficient in the arrangement of the circumstances which encourage the open-ended, exploratory use of acquired skills, for which I will reserve the term liberal education. The main reason for this is that school is obligatory and becomes schooling for schooling's sake: an enforced stay in the company of teachers, which pays off in the doubtful privilege of more such company. Just as skill instruction must be freed from curricular restraints, so must liberal education be dissociated from obligatory attendance. Both skill-learningand education for inventive and creative behavior can be aided by institutional arrangement, but they are of a different, frequently opposed nature. ”
