There are one or two other features about “cruelty” and the mental conditions leading to and arising from it, which, however uncanny and troubling, should be carefully considered when public opinion is roused in regard to its repression. Among these is the fact that the word is freely applied to the mere infliction of pain without consideration of the question as to whether there is a guilty mind determining it. Storms and frosts are called “cruel” by poetic license; but it is probably quite wrong to call a cat or a tiger cruel. These animals take pleasure in playing with their prey, as they would with an inanimate ball or mechanical toy. There is no reason to suppose that they are conscious of the infliction of pain or take pleasure in pain as pain. And so it must happen sometimes with thoughtless human beings who disregard the pain which they cause, when eagerly engaged in “sport” or in the pursuit of some all-absorbing and consuming purpose. The whole subject of cruelty is a distressing one, but should not on that account be misapprehended or dealt with wildly and blindly. Twenty-five years ago a Royal Commission sat which was appointed to inquire as to what restrictions, if any, it was desirable to place upon the practice of making experiments on animals for physiological and medical purposes. As a result of its labours an Act of Parliament was passed which made definite regulations for the purpose of preventing unqualified persons from indulging in reckless experiments on animals. There were stories circulated by the agitators then--as there are now--to the effect that medical students perform horrible and painful operations (vivisections, as the agitators term them,) on live animals in secret or with the connivance of their teachers. It was proved twenty-five years ago that these stories were false. At the same time an elaborate law was passed to satisfy the emotional persons misled by the agitators, which made it necessary for an experimenter (1) to have a licence (dependent on a certificate as to his competency); (2) that he should use anæsthetics; and (3) that experiments should only be carried out in licensed laboratories.
