The term "dumb beast" suggests a degree of intemperate, presumptive superiority over other life forms that may well be ill-advised considering that one day our mortal bodies will be food for worms and microbes, which see us as such "dumb beasts" as well! Is it not better that we humble ourselves and be respectful of life, as we all emanate from one and the same spirit whatever our form may now be, or that of others!
