“I have been opposed to vivisection for many years; not just because it is unbelievably barbaric and unforgivably cruel but also because it is worthless, wasteful, inaccurate, uninformative and dangerously misleading. The cruelty is indefensible and an affront to human dignity, but in a desperate attempt to justify their evil practices many vivisectors still claim that what they do helps save human lives. They are lying. The truth is that animal experiments kill people and animal researchers are responsible for the deaths of thousands of men, women and children every year; they are also directly responsible for a massive amount of human suffering.”

“Total abolition [of vivisection] … will be achieved sometime, when the conduct of humanity toward all that breathes and suffers shall be governed by ideas of altruistic equity.”
