Some years ago the attempt was made to obtain the view of animal experimentation held by certain classes of intelligent men and women. One view of the practice is that which regards it merely as a method of scientific research, with which morality has no more to do than it would have in determining in what direction a telescope should be pointed by an astronomer, or what rocks a geologist should not venture to touch. A statement embodying the views of those who favour unrestricted vivisection included affirmations like these: "Vivisection, or experimentation upon living creatures, must be looked at simply as a method of studying the phenomena of life. With it, morality has nothing to do. It should be subject neither to criticism, supervision, nor restrictions of any kind. It may be used to any extent desired by any experimenter--no matter what degree of extreme or prolonged pain it may involve--for demonstration before students of the statements contained in their textbooks, as an aid to memory,....or for any conceivable purpose of investigation into vital phenomena.... While we claim many discoveries of value,....yet even these we regard as of secondary importance to the freedom of unlimited research." This is the meaning of free and unrestricted vivisection. Its plainness of speech did not deter very distinguished physiologists and others from signing it as the expression of their views. One can hardly doubt that it represents the view of the physiological laboratory at the present day. Sixty years ago this view of vivisection would have found but few adherents in England or America; to-day it is probably the tacit opinion of a majority of the medical profession in either land. One may question whether any similar change of sentiment in a direction contrary to reform has ever appeared since Civilization began. We shall endeavor to show, hereafter, to what that change is due. Absolutely opposed to this sentiment are the principles of what is known as "antivivisection." According to this view, all vivisection is an immoral infringement upon the rights of animals. The cruelties that accompany research will always accompany it, until all scientific experimentation upon animals is made a criminal offence. From a statement of opinion giving expression to this view, the following sentences are taken:
