"Those truly natural wants, which reason alone, without some other help, is not able to fence against, nor keep from disturbing us. The pains of sickness and hurts, hunger, thirst, and cold, want of sleep and rest or relaxation of the part weary'd with labour, are what all men feel and the best dispos'd minds cannot but be sensible of their uneasiness; and therefore ought, by fit applications, to seek their removal, though not with impatience, or over great haste, upon the first approaches of them, where delay does not threaten some irreparable harm. The pains that come from the necessities of nature, are monitors to us to beware of greater mischiefs, which they are the forerunner of; and therefore they must not be wholly neglected, and strain'd too far. But yet the more children can be inur'd to hardships of this kind, by a wise care to make them stronger in body and mind, the better it will be for them."
