"There will come a time when the world will look back to modern vivisection in the name of science as they now do to burning at the stake in the name of religion."
"Animals themselves cannot plead their cause, and those who plead it for them have no obvious financial or other selfish interest in the issue, although many may have “vested” their emotions in it. When we turn to special gain from maintaining existing practices, special loss if they were to be changed, we find a large number of groups whose views might be discounted. Butchers, furriers, hunters, cattlemen, chicken farmers, scientific experimenters on animals would, unless compensated, all have to suffer significant personal loss if we were to change our practices. They cannot therefore be expected to see the moral issue without the distortion of special interest. The scientists might claim that in their case their own interest coincides with a universal human interest, but I think the butcher and the furrier could make a similar claim[.]"

Animal testing, also known as animal experimentation, animal research, and in vivo testing, is the use of non-human animals, as model organisms, in experiments that seek answers to scientific and medical questions. This approach can be contrasted with field studies in which animals are observed in their natural environments or habitats. Experimental research with animals is usually conducted in un

"To what extent do we have a right to torture animals? … Experiments are torturing animals, lets say. Thats what they are. So to what extent do we have a right to torture animals for our own good? I think thats not a trivial question."
"In concluding these papers, I hope I may be permitted to offer a few words in favour of anatomy, as better adapted for discovery than experiment. … Experiments have never been the means of discovery; and a survey of what has been attempted of late years in physiology, will prove that the opening of living animals has done more to perpetuate error, than to confirm the just views taken from the study of anatomy and natural motions."
"As the main work of civilisation has been the vindication of the rights of the weak, it is not too much, I think, to insist that the practice of Vivisection in which this tyranny of strength culminates is a retrograde step in the progress of our race—a backwater in the onward flowing stream of justice and mercy, no less portentous than deplorable."
"At present ... the difference between an animal-experimenters laboratory and a torture chamber is often imperceptible from his victims point of view."
"How fortunate we didnt have these animal tests in the 1940s, for would probably not have been granted a licence, and possibly the whole field of antibiotics might never have been realised."
