Yet another monument, dedicated to the animals 'sacrificed' on the altar of science is at the University of Guelph, in Ontario. This site is unique in the fact that an annual memorial service is conducted which recognizes the impact animals have made in the lives of human beings. A plaque at the stone marker reads: "In recognition of the animals used by the University of Guelph community in support of excellence in teaching and research" (p.223-5).
But alas, as interesting as these monuments are, their very existence is a kind-of contradiction. Such people acknowledge that these creatures are sentient, and 'human-like' (in the fact that we can extrapolate their test results). If these characteristics are scientifically accepted, then it remains to be seen how such creatures can be used against their wills (non-consenting). This is the moral problem with using these kinds of animals in experiments.
In a way, the existence of monuments actually deter a moral advancement in our treatment of animals, as they teach us that, yes, animals are worthy of our gratitude and sympathy, but, in the same breath, we are justified in using them as a means solely to our ends.
