not cavil with the statement that man should put reasonable limits to the amount of suffering he inflicts, and confine this within as narrow a range as possible—always requiring for the death or suffering inflicted some tangible advantage.
Moreover, if the question should be raised as to whether such advantage will result, the ordinary man will as a rule, where the matter lies beyond his personal ken, take expert opinion before intervening.
He will, for instance, be prepared to be so guided in connexion with such questions as whether disease could, if more knowledge were available, be to a large extent prevented and cured; as to how far animal experiments would contribute to the acquirement of that knowledge; and as to how far the physical suffering which might be involved in these experiments can be minimised or abolished.
But not every man is prepared to fall in with this programme of inflicting physical suffering for the relief of physical suffering.
