Thomas Campbell Foster, Popular Science Monthly (1884)
“ Hence all such care of self as is shown by attention to bodily health, by the careful culture of personal good qualities, by just apportionment of time to personal requirements, and so forth, may be regarded as of the nature of duty. In such degree as pleasure, recreation, change of scene, quiet, and the like, are necessary for the maintenance or improvement of the health, the care to secure these, so far from being held to be a concession to self, should be esteemed a most important point in "the whole duty of man." ”
