sweating and fleecing one's fellow-men come under this category.

_Then_ would come the evils which arise out of purveying physiological
and psychological refreshments and excitements, which are, according
as they are indulged in temperately or intemperately, grateful and
innocuous, or sources of disaster and ruin. The evils which are
associated with the drink traffic and the betting industry are typical
examples.

_Finally,_ there would come into consideration the evils of death or
physical suffering deliberately inflicted by man upon man with a view
to preventing worse evils. The evil of war would come under this
category. In this same category might also come the much lesser evil
of punitive measures inflicted upon criminals. And with this might be
coupled the evil of killing and inflicting physical suffering upon
animals for the advantage of man.

We may now consider how the rational legislative reformer would in
each case go to work.

He would not start with the assumption that it _must_ be possible by
some alteration of the law to abolish or conspicuously reduce any of
the afore-mentioned evils; nor yet with the assumption that, if a
particular alteration of the law would avail to bring about this
result, that alteration ought necessarily to be made. He would
recognise that many things which are theoretically desirable are
unattainable; and that many legislative measures which could perfectly
well be enforced would be barred by the fact that they would entail
deplorable unintended consequences.
