It is inexcusable for scientists to torture animals; let them make their experiments on journalists and politicians.
All life is an experiment. The more experiments you make the better.
All my time not devoted to my master’s service was spent either in prayer, or in making experiments in casting different things in moulds made of earth, in attempting to make paper, gunpowder, and many other experiments, that, although I could not perfect, yet convinced me of its practicability if I had the means.
Most of the time, those who use animals in experiments justify that use by pointing to alleged benefits to human and animal health and the supposed necessity of using animals to obtain those benefits.
Most importantly, I agree that the truth of these matters should be determined by interpretation of scientific evidence – experiments, fossil studies and the like.
Chemistry, until my childhood, not that long ago, was regarded as a calculating device. Because you couldn’t reduce to physics. So it’s just some way of calculating the result of experiments. The Bohr atom was treated that way.
When, as an undergraduate, I began experiments on these slime molds in 1940, only one other person, Kenneth Raper, was working on them at that time. In fact, he discovered the model species Dictyostelium discoideum, which is the species used in the majority of the experimental work today.
Experimental economics is about conducting experiments: bringing economics into the laboratory or creating controlled conditions in the field that allow us to understand better what we are seeing in less controlled circumstances.
