All Things Considered
resistance were not only not opposite, but were the same thing. They are the same contemptible thought that conquest cannot be resisted, looked at from the two standpoints of the conqueror and the conquered. Thus again teetotalism and the really degraded gin-selling and dram-drinking have exactly the same moral philosophy. They are both based on the idea that fermented liquor is not a drink, but a drug. But I am specially certain that the extreme of vegetarian humanity is, as I have said, akin to the extreme of scientific cruelty—they both permit a dubious speculation to interfere with their ordinary charity. The sound moral rule in such matters as vivisection always presents itself to me in this way. There is no ethical necessity more essential and vital than this: that casuistical exceptions, though admitted, should be admitted as exceptions. And it follows from this, I think, that, though we may do a horrid thing in a horrid situation, we must be quite certain that we actually and already are in that situation. Thus, all sane moralists admit that one may sometimes tell a lie; but no sane moralist would approve of telling a little boy to practise telling lies, in case he might one day have to tell a justifiable one. Thus, morality has often justified shooting a robber or a burglar. But it would not justify going into the village Sunday school
