Enquire within upon everything

2040. Crying. If we Inquire into the Cause which produces the crying of infants, we shall find that it seldom originates from pain, or uncomfortable sensations, for those who are apt to imagine that such causes must always operate on the body of an infant, are egregiously mistaken; inasmuch as they conceive that the physical condition, together with the method of expressing sensations, is the same in infants and adults. 2041. Difference. It requires, however, no demonstration to prove that the state of the former is essentially different from that of the latter. 2042. Power. In the First Year of Infancy, many expressions of the tender organs are to be considered only as efforts of manifestations of power. 2043. Exertions. We observe, for instance, that a child, as soon as it is undressed, or disencumbered from swaddling clothes, moves its arms and legs, and often makes a variety of strong exertions; yet no reasonable person would suppose that such attempts arise from a preternatural or oppressive state of the little agent. 2044. Exercise. It is therefore equally absurd to draw an unfavourable inference from every inarticulate cry; because, in most instances, these vociferating sounds imply the effort which children necessarily make to display the strength of their lungs, and exercise the organs of respiration.
