Scientists should not do animal testing if there is any alternative, but subject to that, I would support it on grounds of the medical benefits.
Animals, whom we have made our slaves, we do not like to consider our equal.
Medical science has proven time and again that when the resources are provided, great progress in the treatment, cure, and prevention of disease can occur.
Michael J. Fox
As soon as you concern yourself with the 'good' and 'bad' of your fellows, you create an opening in your heart for maliciousness to enter. Testing, competing with, and criticizing others weaken and defeat you.
