Ethical Considerations 
To use either human or non-human animals for purposes that are not in their own 
interests is both ethically unjustifiable and , in the long run, counter-productive.

Fortunately, there are many who, while deeply and appropriately concerned for the

primary concern.

One cannot intelligently assess vivisection in isolation from animal exploitation in other 
areas of human life: for food, furs, leather, in so-called sports, in movies, in the wild. 
Vivisection, properly seen , is simply one variation on the cultural theme of animal 
sacrifice.

The use of any particular animal— say, a sheep— in medical research is more important 
than its use as lamb chops.
