Charles Richet used animals to verify his research on anaphylaxis. Read his Nobel Lecture on how dogs were used in his experiments. However, with his acquired spirit world insight, this is his statement today:
Use of Animals in scientific research/experiments
I deeply regret the suffering I inflicted upon animals in my scientific medical research. I was not aware of the implications that I brought into being. Animals are, as we all are, God’s creations, and the suffering that you inflict upon an animal, inflict upon a Creation of God, will be your suffering when you have the spirit world insight, as I genuinely have today. We love animals; we love human beings; we love God’s creations, the true nature of life itself. To my colleagues, I would say: use other methods to obtain good results in your scientific research. We are all one. What you do to one specimen, you do to all. It is impermissible to inflict suffering on any of God’s creations.
