Mary Everest Boole,
Preparation of the Child for Science
(1904)
“ Sabbath, Jubilee, Holy Days, Holidays, mean, in fact, time to renew our force for future work by getting our relations with unseen forces, with nature, with man, and even with tools, more true, more perfectly harmonious, more elastic and easy than is possible while the conscious mind is acting on the relation. Begin therefore as early as you can to set up in the child's mind what one may call a Sabbatical rhythm in science; a clear distinction between the time when he is being taught by man and the time when he is free to investigate or experiment as he pleases. ”
